Don't look at the Sun!

Update 5 June 2012: Over the next few hours the planet Venus will transit the Sun. This will be visible from many parts of the Earth. Remember to observe with safe solar filters. You can also view the whole thing online via LCOGT, The Royal Astronomical Society or NASA Edge.

Every time there is a solar eclipse you will find astronomers warning you to never look directly at the Sun. Even more importantly, you should not look at the Sun through a telescope unless you have a professional solar filter that covers the front of the telescope. Why?

The Sun is very bright and by focussing the light onto the back of your eye (the retina) with or without a telescope, you are putting a lot of energy (both optical light and infra-red) onto a tiny area. At some point in your life you may have tried to set paper on fire using a magnifying glass, so just think about that being done to the back of your eye. It isn't nice. Even more scarily is the fact that the retina of your eye does not have pain receptors, so you will not even feel the damage being done. It may not even become apparent until later.

Last year, I decided to try to demonstrate just how dangerous looking at the Sun is. Luckily, I am too sensible to use my own eye for this purpose, so I decided to use a green grape instead. It is round and squishy, so vaguely resembles an eyeball. However, a grape doesn't have its own lens to focus the light onto the back of it ,so I reckon it should fare better than a human eye. Anyway, not knowing exactly what to expect, I used some pliers to hold the grape at the focus. For the first few seconds not a lot appeared to be happening. If it was your eye there in place of the grape, you would be cooking your retina in an irreversible way. Anyway, I was slightly suprised a few seconds later when the sunlight had burnt through the outer layer of the grape and hot grape juice squirted out. It sprayed the eyepiece. I made a rather poor quality movie of this, complete with the sound of sizzling grape. If you click on the image you should be able to see it (WARNING: 2.1MB MOV file). The result is not good.

Not only do you blind yourself, but you may damage the optics of your telescope. So, remember folks, NEVER LOOK DIRECTLY AT THE SUN. If you want to observe the Sun, check out the SOHO website or find someone with a solar telescope. You have been warned.

Comments: Don't look at the Sun!

"Not only do you blind yourself, but you may damage the optics of your telescope."

You're telling me, that eyepiece still smells of burnt sugar!

Seriously, the heat could destroy coatings on your eyepieces and cause lenses to crack. If you ever buy a telescope that comes with an eyepiece-mounted solar filter, throw it away as it could well destroy your vision if you use it. They may reduce the light in the optical part of the spectrum so that the Sun appears dark, but they generally still let through infra-red light which will cook your eyeball very quickly.

Hey Stuart, you made the bad astronomy blog! There is a very lively discussion going on over there.

I will now use this article in my standard warnings when discussing solar observation.

I must admit that when I first started out, I used the eyepiece filter that came with my chinese refractor. After reading a few articles in astronomy magazines, I rapidly changed to eyepiece projection. WHich has the added advantage that many people can watch with you. It was a hit for the transit of Venus.

I know! I wondered what was happening to my weblogs as the number of readers suddenly increased by a factor of about 150 since this morning. Everyone seems very shy though.

Posted by Stuart on Thursday 06th Oct 2005 (22:26 UTC)

I came over from Bad Astronomy. I'm very impressed by your experiment, but sorry about the eyepiece of your telescope. The price one must pay for scientific endeavour!

I guess you have never played with a magnifying glass and ants. *pop* *sizzle*.

Found by way of j-walkblog. I will be back. And I'm not shy.

That was a cool video! I have never looked directly at the sun with or without a telescope. And thanks to you i never will. I already have bad vison and i dont want it to be any worse!

thanks!!!!!!!!!!

Posted by Alex V. on Friday 30th Dec 2005 (19:42 UTC)

cool video!! im never looking at sun now. thanks for warning me Stuart!!!!!!!! i dont want to hurt my eyes!!!

Posted by avery on Friday 30th Dec 2005 (19:48 UTC)

If you have never looked directly at the sun,you have obviously never driven down a road when the sun is low in the sky.You can't look away,or you could have an accident

The reason it is dangerous during an eclipse is because your eye responds to the average light level ,which is low,& opens its aperture wide.the very narrow but intense light from the small part of the sun which is visible can freely reach the eyes internals

Posted by Bryan Wheeler on Saturday 28th Jan 2006 (14:41 UTC)

so your saying by looking at the sun you can go blind for ever?

E-mail me back

Posted by Andrew on Wednesday 13th Sep 2006 (14:53 UTC)

Andrew, what I'm saying is that looking at the Sun directly is dangerous to your eyeballs. Looking at it though a pair of binoculars or a telescope is even more dangerous.

Posted by Stuart on Thursday 14th Sep 2006 (16:59 UTC)

how dangerous is it tho out of 1 out of 10

Posted by Andrew on Friday 15th Sep 2006 (23:13 UTC)

never ever ever! look directly at the sun and i tell you this from experience. i have looked directly at the sun and now my vision is distorted. i cant see numbers very well anymore and i will never be able to see a straight line again; it will always have a bulge in it. when i close my eyes i can actually see the hole that i burned into the retinas of my eyes by staring at the sun so never under any circumstance look directly into the sun.

Posted by Faith L. on Saturday 16th Sep 2006 (00:53 UTC)

my god and you where looking at the sun for 5 or 10 minits?

i am geting a telescope soon i hope so i am just trying to find out all i can about it

but wat if its not a sunny day?

Posted by Andrew on Sunday 17th Sep 2006 (13:56 UTC)

Andrew, I'll echo Faith's comments that you should do your best not to stare at the Sun. You should certainly not look at it through a telescope unless it is a proper solar telescope with good quality filters on the front to reduce the amount of light going into it. The reason it is dangerous is that the Sun is VERY bright and so much light falling on the back of your eye is very likely to damage the sensitive cells in it.

Generally, if you are getting a normal telescope you will not be looking at the sky during the day so it isn't too much of an issue. Of course there are some occassions when you would want to use a telescope during the day but I suspect those will be sunny days (you don't see much that is astronomical when it is cloudy!). If you do observe during the day, just make sure that you steer well clear of the Sun.

Posted by Stuart on Sunday 17th Sep 2006 (15:09 UTC)

no dont ever look directly at the sun, I did it when i was younger and i went deaf.

Posted by david on Wednesday 08th Nov 2006 (16:29 UTC)

im realy worried about myself. i have an observitory OCD which makes me want to look at things and igzamine them. im worried that i might be overpowered by the sensation and start looking at the sun directly, even using the special methods to protect your eyes wont work cos my complex mind will just say "but what would it look like directly?" i have poor vision now possibly from excessive use of the computer and dont wish to damage my eyes further, i may have climpsed the sun up to 20 times since i was born =O

Posted by jamie on Sunday 12th Nov 2006 (20:26 UTC)

Jamie, try not to worry too much. If you do happen to glance at the Sun with your own eyes you should look away again as quickly as you can and blink a few times. (If there are any optometrists out there reading this they may be able to add some better advice here).

Of course, a much bigger problem would be looking at the Sun with some kind of telescope/binoculars. The best thing to do in that case is never to put a telescope in a situation where you can accidentally look at the Sun through it.

Posted by Stuart on Sunday 12th Nov 2006 (23:26 UTC)

ok, i was also wondering if this only aplys to the sun? i have powerfull disco lights in my room as my regular lighting, and i wasnt sure if this could do any damage. any advice please? thanks for the tips stuart, i tend to find that glimpsing the sun is a common accident, aspecially when the sun is dim and i dont realys its there when looking up. usually when its bright my light sensetive eyes make it impossible to see properly so i couldnt look at the sun anyway :P

i also heard that sun glasses that dont have the national safety mark are actually even worse for the eyes because they make the pupils bigger to let in more light, but dont protect from UV rays courses more damage =\

Posted by jamie on Wednesday 15th Nov 2006 (19:16 UTC)

on a cloudy? hmmmm...well i'll tell you that my uncle and i watched a partial eclipse of the sun on dec 25, 2000 (i think it was 2000) and we saw the whole thing through the clouds perfectly and even took some excellent pictures all through the clouds. on that day the clouds were just thick enough so that we could see the eclipse without the glare and just thin enough so the we could see every detail of the eclipse. it was awesome! however if you were to look at the sun through a telescope you would definitely do terrible damage to your eyes because its heat and light are magnified many times so whatever you do please please please dont use a telescope to look at the sun.

Posted by Faith L. on Friday 17th Nov 2006 (22:05 UTC)

lol that should be "on a cloudy day?"

Posted by Faith L. on Friday 17th Nov 2006 (22:07 UTC)

is it possible to look directly at the sun??? for more than 5 seconds???

Posted by benn9 on Sunday 26th Nov 2006 (23:57 UTC)

Benn9, it is possible but you will most likely do serious damage to your eyes. I would STRONGLY recommend that you didn't look at the Sun for any length of time.

Posted by Stuart on Monday 27th Nov 2006 (09:15 UTC)

i have hade eye problem for a few years ..when i look at writing the bit in the middle i cant see so if the word i was looking at was qwerty all i see is qwe ty..i have had tests they caNT FIND ANYTHING UP WITH THEM .I HAVE BEEN LOOKING ON THE NET FOR SIMPTOMS ..I AM 100% SURE ITS BEEN THE SUN .ARE THEY any treament for it

Posted by john on Tuesday 05th Dec 2006 (17:24 UTC)

John, this isn't the right place to ask for medical advice. If I were you I would contact an optometrist or opthalmologist and perhaps check out the Royal National Institute for the Blind's pages on low vision.

Posted by Stuart on Wednesday 06th Dec 2006 (09:52 UTC)

I should be blind according to this then.

I looked directly into the Sun today for more then an hour. I've spent as many as 3 hours in a row looking directly into the Sun. I've been looking every chance I can for the last 13 years.

I've looked into the Sun from a very young age.

I'm 49 now and getting a little far sighted but no noticable damage from looking into the sun.

I don't reccomend it if you think it will blind you. What you believe come into existance.

But like smoking cigerets, not everyone gets cancer from it.

Oh don't look.

I don't mean to sound like I'm saying to do it.

But I can. Want witnesses? I Got them. Lots

Peace

Posted by Jesus on Wednesday 13th Dec 2006 (07:33 UTC)

Jesus, I really don't believe that your statement is factually correct. However, even if I was to assume that it was, I think that it is very dangerous to make such statements. Despite your claim that you "don't mean to sound like I'm saying to do it" that is certainly what it will encourage. I do not understand what you wish to accomplish by this.

The analogy with cigarettes doesn't really work. Smoking gives you a statistical chance that you could damage a cell in such a way that it reproduces uncontrollably (i.e. cancer). However, allowing large amounts of sunlight direct into your eyes for some time will raise the temperature at the back of your eye. Heating up cells to high temperatures is a very sure way to kill them.

I have a final question. Why would you spend so long looking directly at the Sun over many years?

My son was at school, during break time he decided to stare at the sun for 2 minutes. When he got back home he was watching tv and he kept saying there was something wrong with the colour, he kept seeing pink, then hour later more colours! will this have a long term damage on his eyes?

Posted by marie on Tuesday 23rd Jan 2007 (17:06 UTC)

I would seek medical advice if I were you. It will not have done his eyesight any good and it may have caused long term damage. You should take him to an optician for an eye examination. I hope he turns out to OK.

Posted by Stuart on Tuesday 23rd Jan 2007 (18:54 UTC)

Ever since I learned the dangers of looking at the sun, I have done my best to avoid it over the years. I am OCD so you can imagine how careful I have tried to be. However, playing baseball there were times that I had to stare directly into the sun many times in order to catch pop flys. Today, I walked out without my sun glasses. I came up to a traffic light and had no choice but to look directly into the sun in order to see when the light turned green. The sun was directly behind the signal so I literally had to look directly into it to see when I could go. I am freaking out because I probably looked right at it for about 2 seconds straight. It was so bright that I quickly looked away each time that I glanced up at it. I am worrying myself sick that I may have permaently damaged my eyes. My eyes seem to be working though as of now. Could someone tell me if I should worry about this? If it had done serious damage, would I already know it or could it show up at a later time?

Posted by Glen on Wednesday 07th Feb 2007 (01:08 UTC)

Glen, as far as I know it can take hours to a day or two to see the effects of damage from looking at the Sun. If you are worried, go see an optician or other eye specialist.

Posted by Stuart on Wednesday 07th Feb 2007 (09:50 UTC)

I've already watch directly the sun. The sky was clear, I looked at the sun directly for at least 2 minutes. I didn't feel any pain, and over a year later I don't notice any change in my vision, it is still as perfect as it was. But I don't recommend you attempting this. ( at the moment I was in a very conscious state of mind, and I believed that if I was to look at the sun it would not impair my vision ; seems I was right though )

Posted by Philippe on Monday 19th Feb 2007 (07:30 UTC)

Philippe, out of interest, where was the Sun in the sky (how high above the horizon) at the time?

Posted by Stuart on Monday 19th Feb 2007 (07:48 UTC)

Put your head 45 degrees backward and look straight. That's approximately where the sun was. Not absolutely sure though... But I can tell it was very very bright in the eyes.

i was a a tripper for many years and no longer trip so i have permanent visuals now the sun gives off so many beutifull colors itself it is very hard for me not to look right at at and my girlfriend catches me staring at it and smacks me on the back of the head i cant help it there must be some way to see it without the harmful rays hurting my eyes someone please reply

Posted by scott on Monday 14th May 2007 (16:44 UTC)

Scott, get yourself some eclipse viewing glasses. Make sure they have a CE mark (or equivalent) so that you know they are safe. If you have a lot more money to spend, buy yourself a solar telescope. Both of these methods let you look directly at the Sun but cut out a huge amount of the light to make it safe.

Posted by Stuart on Monday 14th May 2007 (17:13 UTC)

I remember looking at the sun for the briefest of moments when we had the best UK solar eclipse many years ago.

The pain at the time was not good, and I wished I had not done it.

Hi, I drive alot around 6:30, 7:00 PM. I drive the same way every day (to get home) and every time I do it, the sun is always right in front of the car, next to stop lights, etc. I am really frightened about what this could be doing to my eyes. I am wearing a pair of pretty cheap sunglasses, but feel I need more protection. Please advise. thanks

I really am worried about this. email me, ajsellaroli@gmail.com

Posted by AJ on Friday 14th Sep 2007 (19:43 UTC)

AJ, the thing to do in this sort of situation is to limit the amount of light (optical and UV) getting to your eyes. The simplest thing to do is what I do and pull down the sun shade (the thing with the mirror on it attached to the roof over the drivers seat). You can angle that to block the sun but still see some of the road.

As the year progresses this should be less of a problem because the Sun will set at a different time and in a different place.

HOW ABOUT IF ONE LOOKS DIRECTLY AT THE SUN FOR A FEW SECONDS, WITHOUT THE TELESCOPE,ONLY WITH YOUR BARE EYE.DOES ONE GO BLIND?

Posted by ADRIAN on Friday 04th Jan 2008 (04:13 UTC)

When IÃ¢â„¢m a little child a have a weird hobby sometimes in the morning or at daylight I like to see a sun with my bare eyes without any filers and I like it a lot even some time my tears dropping a lot, because after several minutes you will be different colors like rainbow and itÃ¢â„¢s very interesting. Right now IÃ¢â„¢m 35 and my eyes still ok without using any glasses.

Posted by yan on Monday 14th Apr 2008 (02:13 UTC)

I was lighting a piece of wood using a lens. I focused the lens on the wood and watched it make the wood start smoking. This took about a minute. After that, I noticed that my eyesite had a transparent orange circle no matter what I looked at.

Looking directly at the sun focal point on the wood is very dangereous and I should have wore snow blind glasses.

The orange cicles went away in about an hour but I don't know if my retinas are damaged

Anybody care to discuss this.

Posted by Mary Roach on Wednesday 30th Jul 2008 (11:00 UTC)

i looked at the sun for about ten seconds or so and later that evening when i looked at lights ie,candles and lit bulbs the light emitted was PINK.i had a very strange evening lol. vision is back to normal now though thank goddness.

what if you look into the rays when you use a magnifying glass and u see the light from the sun going through the glass when your trying to burn something

Posted by hihihihi on Sunday 10th Aug 2008 (14:37 UTC)

Recently, I was informed of the benefits of looking directly at the morning (rising) sun. Apparently, one should do so without one's spectacles. Also after a minute or so, one should focus on the area immediately above the sun, that is, not looking into the core of the sun. This practice apparently has its benefits and I was asked to visit the website www.sunyoga.info. But now I am confused - is it good or not good to look at the sun. Can somebody please advise?

I've looked at the sun a lot of times directly, it leaves a weird glowing circle in your eye but goes away after about 1 minute, now I see a tiny purple dot wherever I look, but Its hard to know its there unless I'm staring at something,

if you want to know what the circle looks like, look into a light without a lampshade(Not an energy saver one!) then look around

Posted by guy on Friday 07th Nov 2008 (18:28 UTC)

when i was 7. me and my friends used 2 look at the sun i used 2 see people as purple. i used 2 look at the sun for like 5-20seconds this was at break time around 10:25am. but it went after a few mins. for some reasons i can look at really bright lights longer then most people without pain. im now 12 will this cause any problems like when im an adult and stuff. (also i never look at the sun any more and when i used 2 look at the sun i quit after a month or so. and i used 2 look at it once a week or so.)

Posted by Ikram on Wednesday 24th Dec 2008 (18:27 UTC)

Ikram, I'm not a medical doctor or an optician so can't say if you'll have long term damage. As I say above though, there are no pain receptors in your retina so you wouldn't feel it even if you were causing damage there.

Posted by Stuart on Thursday 25th Dec 2008 (02:38 UTC)

Is it bad to look at the sun reflecting off something? The sun is reflecting off the concrete floor behind me and i can see it on the computer screen. Will that damage my vision?

Posted by Jonathan on Wednesday 31st Dec 2008 (18:59 UTC)

Ok so i have this thing (OCD i think) where i keep on looking at the sun. I look at it probably for about 2 seconds every day and sometimes longer. I am very scared that i will permanently damage my vision, so how long do you think it would take to blind you? Is it just as bad to do glances instead of direct staring at the sun? Also i have heard that sunglasses make it worse because your pupils dilate and it still lets in light.

Posted by Comrie on Monday 19th Jan 2009 (19:13 UTC)

I was at the Griffith Observatory in LA a couple hours ago. There was this one exhibit where sunlight from the telescope is reflected onto this plate so it can read the spectrum. My silly girlfriend told me it was cool to look up into the telescope. I looked up, and it was the power of the sun directed onto my eyes. I immediately looked away; it was probably no more than 1/2 a second of looking. Immediately afterwards, they had a dull ache. Since then, I've been having a hard time focusing on objects and trying to read really strains my eyes. Is this only temporary? Does anyone have any info? Am I screwed?

Posted by Bucky on Monday 09th Mar 2009 (02:23 UTC)

ery Interested in this post :Comrie on Monday 19th Jan 2009!!!

I have exactly the same problem. Can remember growing up having comulsions to stare at the sun but it would come and go so it didn't bother me to much. The last 5 years it's got worse and can only link this to OCD. Are quick glances at the sun bad for eyes. Still fear for my eyesight as sometimes stare at the sun for longer. This is really worrying me and dont know how i can get over it. Even have facinations with staring into bright lightbulbs. Have mentioned this to friends but as they can't relate they just laugh as if im not serious. Does anyone know how this comes about as its got so much worse. Please help me and offer some advice please. I have always been fit and healthy bar this very debilitating thing which is making me extremely stressed as dont want to loose my sight! ps...im not crazy!!!

Posted by Zak on Monday 16th Mar 2009 (19:18 UTC)

Around the equator early in the morning the Sun is massive but orange-red... like a previous comment it is impossible to avoid while driving. But based on the grape experiment this shouldn't be a problem since its orange-red the light isn't intense (compared to bright white high in the sky). There is no natural reflex to look away from it. Such a reflex is designed to protect you so would it be correct that it is safe since your body doesn't deem it a threat? Shining a bright desk light in a pitch black room seems to be more injuring. Also playing sports like tennis you are 'forced to look at it'. I tend not look at the actual sun's circle but try to focus on the ball/sky near it. I don't play anymore but it happened alot. While serving you are looking at it for a good 5seconds per serve. What are the implications of that?

Posted by Wade on Wednesday 01st Apr 2009 (16:32 UTC)

The light is passing through a lot more atmosphere when viewed on the horizon but I wouldn't like to guarantee anything.

It isn't safe to assume that because the body doesn't react you are safe. The body doesn't protect you from a build up of carbon monoxide or from a lack of oxygen; in both these cases you can die but your body doesn't really give you a warning.

Posted by Stuart on Wednesday 01st Apr 2009 (18:41 UTC)

so if you did brief glances at the sun over a a span of like 2 weeks that equaled 20 seconds would that be as bad as staring at the sun for 20 straight seconds.

Posted by Comrie on Thursday 09th Apr 2009 (01:54 UTC)

I looked at the sun when there was an eclipse in 1977 uk started to realise there was a permanent dot in my eye with swirly colours in can block out letters completely especially against a white background the optician said she can actually see the hole in my retina i looked at it for about two minutes on and off so be warned NEVER look at the sun makes me realise what a stupid fourteen year old I was especially as i skived school to look at it

Posted by ian on Tuesday 30th Jun 2009 (08:52 UTC)

okay the only reason I found this article is because i'm doing some research because of my own stupidity. Yesterday i was laying by the pool and the sun was right above me so I opened my left eye and looked directly at it for no more then 20 or 30 seconds. Anyway today i've got a blind spot in my left eyes vision about the size of the sun in the sky that it was yesterday. So I got first hand experience that it is extremely dangerous to look at it. I'm only worried is this going to be permanent blind spot in my eye or is it temporary, trying to find an answer before I go see an eye doctor tomorrow.

Dave, you'll get the best advice from your eye doctor than from me. I hope it isn't permanent.

Hi, I'm trying to find some serious and scientific facts abot whether staring at the sun is dangerous or not.

That's because I used to stare at the Sun as a kid whenever I wanted to. Then someone told me not to do it, that it's dangerous and scared me about it.

It was only a few years ago that I stared at the Sun again, after many years. The problem was that I was feeling sick and I was sure that I'd faint. Slowly everything was becoming dark around me and I was losing consciousness. Then I turned my head to the Sun and stared at it until the darkness went away.

Anyway I'd be very very angry if it turned out that it's not so dangerous at all. Because, as a kid, I wasn't afraid of the Sun, I liked my "staring sessions". And now that I'm reading about all these people here in the comments who still stare at the sun, I feel cheated. I believe in science and I believe scientists but now I'm kinda starting to feel as if some uberreligious commander told me: "Don't stare at the Sun, it's the devil that will take your soul". If scientists are prepared to just lie and proclaim uninvestigated facts as total truths, then I have no more reason to believe them as I would have to believe in ghosts, gods and other mumbojumbo. PLEASE people, do some studies, test, whatever...but get your facts straight. Just because something sounds logicall doesn't mean it's true.

I'd say that for some people, staring at the Sun is dangerous and for some it is not! So if you have a need to look at it and had that need since you were a kid, maybe your eyes are ok with it. Btw I have a perfectly healthy sight.

Hi everyone out there...fact, staring at the sun is dangerous...but haven't we all been in a situation where we have been exposed to the sun...whether at dawn or dusk it is unavoidable and certainly would have damaged our eyes by now...are you telling everyone from your fears and comments here that staring for a few seconds at the sun will actually cause permanent damage to the whole human race, c'mon we are all exposed to the sun everyday in every way, if you just glanced for a few seconds that will not hurt you at all, we have all done it at some time in our lives, just don't stare for prolonged periods and use common sense...peace

Hello,

A while back, say a month or so ago, I went upstate to visit my friend. We generally catch the sunrise from atop a residential hill that overlooks the bay. That morning I swear I stared at the sun for 20 minutes. It was very low on the horizon, as it had just risen. But I've been very worried that I might end up blind one day because of it. I don't have any noticeable damage to my vision...yet. But who's to say that in 20 years I won't be blind because of it.

The Sun literally is the most amazing thing in the solar system, without it, we'd all be without life. I don't know what I was thinking, I guess I forgot (or no one ever told me) that looking at the sun was a bad idea. I figured that was only during eclipses. No idea where the logic was in that... but nonetheless, I really hope that I don't go blind one day.

I'm going to assume that if there were any damage, I would be aware of it. Unless I'm just an idiot and can't tell that my own vision is distorted.

Posted by Brandon on Wednesday 04th Nov 2009 (11:15 UTC)

I use to stare at the sun when i was a kid, now I am wondering if it did hurt my eyes, I am noticing damage and I use to be able to see better, plus I see little floters, now. almost like I can see thought a microscope and my normal vision at the same time, I belive this is me seeing the bad things in my eye, I have done it recently as well. this is why I looked this up. I am making ir filters for my camera. and thought I could use it to look at the sun, but I guess not I was on the hoya ir filters web page and they told me not to use the filter to look at the sun, it will still hurt my eye, and you can hardly see thought a band pass filter, I am talking about a filter with a pass around 700 nano meters to like 1000 nano meters.

I find these comments really interesting. Personally I look at the Sun all the time. It usually turns a bluish color and when I look away I can see a pink circle where the Sun used to be. This effect goes away in usually a few seconds, or occasionally a minute or two after I look away. I currently do not have any problems and I find it hard to believe that I will develop serious problems later in life. I think this is because generally, I look at the sun when it's high in the sky which means it's a brighter day and our apertures (pupils) are smaller to allow less light to come in. The same effect occurs at sunrise/sunset because since there is so much light, that light doesn't actually damage our eyes as much. I do, however agree with not staring during an eclipse since the every thing is darker meaning our pupils are open wider. Also, I want to thank you for your video because that illustrates how dangerous it could be to look through a lens. I have experienced this once when I looked through binoculars at the sun. It was extremely intense, so I looked away after less than half a second, and I was instantly aware of the possible damage I could have done had I looked longer (I could actually feel heat on my eye). But, generally, I think people are overreacting when they think they will go blind by looking at the sun with their naked eye for just a few seconds. I think your body's natural reflexes will help save you some damage.

Posted by Amir on Friday 13th Nov 2009 (07:32 UTC)

P.S.

I recently (a couple years ago) passed an eye exam with flying colors, so I know that I haven't done any damage to my eyes to date.

Also, I have to disagree with your comparison about carbon monoxide. It's a different situation entirely, The molecule is more attracted to red blood cells than oxygen so the gas actually sort of tricks the blood into thinking it's O2 and once they bond it's too late. But with the eye, our body is actually designed to counter the amount of light by making the pupil smaller. (like a camera automatically makes its aperture smaller when there is a really bright light. What is dangerous, and thus comparable to the carbon monoxide is an eclipse. Like I said before, because the surrounding area is dark, our pupils dilate to enable us to see things. The extremely bright nature of the sun will damage your eyes. So in a sense, our eyes are "tricked" during an eclipse, but not during everyday viewing since our eyes are designed to adjust. I don't recommend staring for a long time at the sun because eventually the rays do burn a hole in the retina, causing permanent damage. Staring for just a few seconds won't do permanent damage, although it may damage it a little, the retina can correct the issue.

hi i live in ireland near knock. you might have heard about the recent apparitions there of mary. Many have claimed the see the sun dancing in the sky.

i wasnt in knock but on the day of the apparition at 3.00 the time mary was suppose to appear i was walking to the shop,when i just clanced at the sun that exact monment i couldnt believe my eyes ,it was spining on uts axis and moving in a zig zag pattern towards the earth,it was changing colours. it wasnt bright but a small disc and was easy to look at it. i stared at it for a half an hour,also there was another woman there who stared at it for the same time period.

after that my eyes were completly fine. A month past and i was walking to the shop again at 9.00 in the morning, this time the sun appeared to be much brighter than the first time but again was spining and moving in a zig zag pattern..shocked again i rang my friends who also seen it.it was happening all day and when we were travelling in the car i would stare at it for a while and look away.

later that day i had a blind spot in both eyes, i cant make out peoples faces far away and i find it difficult to read. im also suffering from bad head aches. ive been in the hospital all week , and they took photograghs from the back of my eye.they told me ive burned the retina in my eye badly. they were shocked at the effects and seemed to be angry at what was going on in knock.

they said that the sun does not spin ,its your eyes playing tricks.

I still believe something is happening with the sun,i have never seen such a thing in my life. why hasnt any astronmists noticed this before...thousands have witnessed it but only in holy places. like megjagory ..fatima ..knock. im not saying its a holy phenonemon. but i do think the sun is 'dancing' as people call it.

the doctor says that my eyes might heal themselves im hoping that this bind spot will get better as im very distressed over it.

i would not recommend to look at the sun under any circumstances!!...do not look at the sun dancing in the sky...you dont want a blind spot trust me!

Posted by marie-clare on Friday 27th Nov 2009 (16:02 UTC)

Marie-clare, why do you think the object or effect you were looking at was the Sun?

Posted by Stuart on Friday 27th Nov 2009 (16:28 UTC)

yes definitely was the sun no doubt about that!

Posted by Marie clare on Saturday 28th Nov 2009 (12:40 UTC)

Sorry, I wasn't asking if you were convinced that it was the Sun. I was wondering what it was about it that made you decide that it was the Sun?

Posted by Stuart on Saturday 28th Nov 2009 (18:03 UTC)

when it stopped spining it returned to its original position and we could not look at it any more as it was too bright. what else could it be...and since it was what i was looking at that burned the retina in my eyes...im assuming it was the sun!

Posted by Marie-clare on Sunday 29th Nov 2009 (02:17 UTC)

i agree with many comments on this board reason im reading intosuch things is because abouta year ago my eye sight started deteriating i told my optiction he said it was something called floaters and there was nothing he could do it was "normal" well in anger afew days later i looked at the sun twice both times 3 seconds each after i have had likelines in my vision cant see in the dark ect so i go to the hospital and he said after all this they could of done something about my condition so ive demaged my sight forever for no reason... moral of the story dont risk looking at the sun if you cant handle the damage it will have done that i will and you wouldhave to live with for ever.. Gc

this is extremely useful information for astronomers. however for people with office jobs this might be important too.

Posted by jen on Tuesday 08th Dec 2009 (02:03 UTC)

These comments are actually quite interesting. A lot have said that after staring at the sun for a few seconds, and then looking away, they see a pink circle in their sight in the same position as the sun used to be.

This happens to me as well - whenever I look at a powerful lamp for, say, 5 seconds, and then look away, closing my eyes tightly, I see a pink/purple circle form where the bulb was in my vision. It fades away quite quickly though - after around 3 seconds it would be gone.

What I'm trying to say is, what's with all the pink??

Posted by Stephan on Saturday 12th Dec 2009 (18:22 UTC)

once i looked at the sun directly just because my sister told me. we both looked at it for several seconds and then all looked green and sort of blurry. i didn't know it was dangerous.

maybe that's why i use glasses right now.

Posted by fernando on Wednesday 30th Dec 2009 (05:15 UTC)

i dont think looking at the sun at evening when it is about to set can hurt your eyes.. it looks bright orange..its not even feelng hot at that time and even no spots can be seen even if we look at it for a long time..infact it looks perfectly round and in a 3D effect...if spots cannot be seen after looking at it at that time how can it damage the eyes?just my experience...well not recommended at all in the hours between...

Posted by vinod on Monday 04th Jan 2010 (03:28 UTC)

The colored spot on your eye is called an "afterimage." Afterimages happen when the color-sensitive cells on the back of your eye get bombarded with a lot of colored light that stimulates them heavily. For some time afterwards, they will keep giving false reports that they're seeing a color, even if they really aren't. Eventually, they calm down. That's where the pink or green spots are coming from.

An afterimage doesn't mean your eyes have been damaged all by itself; it's easy to get them, even from light sources that aren't all that bright compared to something like the Sun (or the beam of a laser pointer, which focuses about the same amount of light on a given spot as the Sun does- ask someone with a physics degree to do the math if you don't believe me).

Very bright light (like direct sunlight or the beam of a bright laser pointer) *can* cause real, permanent eye damage. You won't feel any heating or pain, because there aren't any nerves inside your eyeballs to pick up the pain. You just burn out patches of cells.

How much exposure it takes to cause damaging burns on the eye is a tough question. It's best to avoid looking at anything that intense at all, but if your child looks at the Sun for a few seconds or something it doesn't mean they're going to go completely blind. Staring into the Sun for minutes or hours, on the other hand, is foolish and self-destructive.

Posted by Simon_Jester on Saturday 09th Jan 2010 (05:01 UTC)

Stuart:

How about in the morning, when the sun is just rising? On some days in Hawaii, we have "vog" (volcanic haze) that makes the sun appear very round, very red/orange, and has no blaring sunrays. It's like the sun on the Japanese flag. Could I glance then?

Thanks!

My Name is Rosemary, and I did something foolish when I was 11 years old. I am now 22 years old..

Ã‚Â¨

I looked at the sun with a binoculars, for a while. When I came back to the house, the lightbulb was pink. I was so foolish , but now I am curious about eye damage.

I can see things perfectly. I have never needed glasses....

I am worried about the damage caused.

How long does it take for damage to show? Years?

In what ways would the damage present itself?

Strange, when I was 6 or 7 I looked directly at the sun. And if anything unless I am mistaken I feel that since that day i have better eye sight.

Posted by DAN on Saturday 08th May 2010 (09:19 UTC)

I have also spent hours staring at the sun. As a child, it felt sooo good. Like it was tickling my brain. I did it almost every day. Now, though, at age 28, it does not feel good and I rarely (maybe once a year) do it. Supposedly the Yogi who doesn't eat or drink gets nourishment from the sun. Part of my wants to scream a skeptic roar but another part is irresistibly interested.

At school when i was younger 3-4 years ago , i was doing stupid shit with the guys the one who look longer at the sun...and honestly it wasnt hard at all to look at it(even if i got blue eyes) and keep looking....for.....geez..30-45seconde for sure yeah im pretty sure around that. and i did that alot of time! like....min5-6 time???8-9maximum

im pretty sure and aware that it wasnt good but honestly it i could erase that i would so badly i dont think i noticed the damage YET im wearing glasse dailyfulltime too...

One thing is sure!

Don't Look At The Sun!!!

ITS BAD FOR YOU'RE PRECIOUS EYES!!!

Posted by Max on Tuesday 15th Jun 2010 (07:50 UTC)

Just so you know... there is a meditative practice calles "solar gazing" where practitioners dileberately look straight into the sun with the naked eye. It is typically practiced when the sun is relatively low on the horizon. I've done it many, many times without any damage... I still have perfect eyesight. So the old adage of "don't ever look into the sun" is not exactly correct. More info here: http://mintaka.sdsu.edu/GF/vision/Galileo.html.

When I was a little kid my mother told me not to stare into the sun. So once when I was six I did.

At first the brightness was overwhelming, but I had seen that before. I kept looking, forcing myself not to blink, and then the brightness began to dissolve. My pupils shrunk to pinholes and everything came into focus and for a moment I understood.

The doctors didn't know if my eyes would ever heal. I was terrified, alone in that darkness. Slowly, daylight crept in through the bandages, and I could see. But something else had changed inside of me. That day I had my first headache.

Posted by Maximillian Cohen on Sunday 19th Sep 2010 (06:52 UTC)

I have only looked at the sun for one or two seconds at a time so i have never had any problems and hope I never do. To everyone out there, NEVER LOOK AT THE SUN! It is VERY DANGEROUS!!!

I look directly into the sun for prolonged periods of time with no ill effects. I will provide video or photographic proof if disputed. hi to the guy above - fellow sun drinker. We must have the same DNA.

I agree - believe it will do damage and it will. Otherwise enjoy the sensory overload of photons.

My Story goes like this!

Here is my story As a word of Warning I cannot stress the fact to say like as the author stated NEVER EVER LOOK AT THE SUN AT ALL FOR ANY REASON IF you do WEAR SUPER PROTECTIVE SHADES when for example going to the beach if through a telescope go to day sun party were lots of astronomers look at the sun with special filters Etc. I will Tell my story now and Please If you are reading this Pay close attention. Because I'm very serious.

When I was small I knew that my life would be about astronomy as I have always Been VERY Passionate about it. At the age of 10 I was very into astronomy and I asked my dad If I could get a telescope. He said yes. So we headed of to a department store And got myself a 50mm Plastic Refractor. The days went by and I was happily viewing planets and the moon.

One day I thought What the heck I can View the Sun if I put A black plastic bag over the eyepiece! It was the dumbest thing I ever did. I looked one second and saw a little of the sun but the bag ripped and the sunlight came through and my quick reflexes pulled me away. I saw it for a sec and 1 Second makes a big difference. Years later at 16 years old I started to see blurry. I needed glasses. 3 Years later and I'm 19 I was stupid once more! about 2 days ago I decided hmm I can make a 60mm Refractor and Stack Planetary Filters to darken the sun out! And thats what I did. I viewed it and Well It was ok. 2 Days later and I think That IR rays from the sun have come through. I can see fine of course But my eyes started hurting.

I put Eye Droplets in my eye and I feel better now. My Story goes to show that While it may look harmless Please don't Do it. I WILL NEVER EVER LOOK AT THE SUN EVER AGAIN. My next plan is to get SOLAR BAADAR SAFETY Film to put over my scopes BUT I will not look through it I will use a camera to do the work for me! I hope in the coming months and weeks that my eyes get better. I feel That its going to be ok. But I also feel that I may have done some damage. I see none yet But I will treasure my eyes from now On its a lesson learned and am glad I can still see. That is why I have decided to be an astronomer as well. My eyes have shown me amazing things. Its the 1 Human Body part that we All need to really function well. So stay safe! thank you For reading my story. And Happy Halloween All!

Thank you for posting the video! I've always been kind of curious and have battled with this part of my personality every time there is a solar eclipse. I'd think "just once? A quick peak?". But the sight of the charred "bullethole" in that grape has made me lose any remaining appetite for sun-gazing.

I have starred at the eclips of the sun whenever it accured. The first one that I starred at was in the summer of 1961 or 1962 or 1963. Never took my eyes off of it till it was complete. I didn't feel anything different in my eyes during that time or after. Later in my life I starred right at another eclips of the sun from start to finish. I can't remember what year that was. Maybe in the summer of 80's?

What would the systems be?
