Your eye has a converging lens, so if you ever played with magnifing glass you know the effect of such lens. It concentrats all the light in one dot, which is on the back of the retina.

You are asking to get burned without it, let alone the worse things that could come from it later in life. WEAR THE SUNTAN LOTION!

Ha ha ha ha! Good God! It is only bad for your eyes if you are sitting on the roof of the vehicle while in motion.\n\nI don't know where that idea came from but to put your mind at ease, your eyes are constantly moving, and do so to compensate for movement of the body, when walking for example, other wise our vision would be like looking through a shaky hand held video camera. The same goes for when we are in a moving environment such as a car or a bus.\n\nI assure you that your eyes will not fall out nor will your hair grow curly if you eat the crust on the bread.

Hi !  Alan here.  Red-Head ....\n\nI've spent half of my summers as a kid torched like a lit match.  Ruined both Carribean cruises that my parents brought me along on (heck I was like 12 and 14 at the time and would really rather have gone when I was 20-something).\n\nThere have since, as an adult, been innumerable float trips in shiny silver canoes ... you get burned from the top and the bottom.\n\nWell, it wasn't the threat of skin cancer or anything like that.  It was honestly, just the pain. Period.\n\nYeppers ... I wear sun screen now and put in on the kids whenever we go out for extended time in the summer sun.\n\nI hate rubbing that stuff on me or anyone else (I actually eat popcorn with chop-sticks so as to not get my finger greasy ... I know, major-weird) ... still, it's made for whole lot more enjoyable vacations for the past 10 years or so !

sun has huge amt of hydrogen atom which under the high temp. undergo nuclear fussion reaction to produce helium ion with emission of huge amount of light & heat......so becoz of this light it always shine...& bcoz of that heat the nuclear reaction keep to continue......

too much sand blowing around, plus with the direct sun, you wont be able to see your screen anyways.  i would not take mine to the beach.  \n\nplus, youre at the beach...watch the hot bodies instead!

Only if the wax in your wings melt if you fly too close to the sun...seriously though...there have been cases where people mix it with spirits and go on a binge...serious complications...it is a stimulant.

well first of all i think it depends on your surrondings. if you;re in a polluted city area then it might have caused the water in ure eyes. secondly, if you put any sort of eye makeup, you should probably was ure eyes and i'm sure ull be fine. Also, use some eyedrops, Visine maybe.

Maybe get it checked out by an optician.  If your pupils are dilated in strong sunlight you could be getting damage to the inside oif the eye...;

Exposure to sunlight can (obviously) cause burns.  Over time, over-exposure can lead to cancer, as harmful solar radiation causes mutations in the DNA of your skin cells.  Sunight can also burn your retinas by being magnified by the lenses within your eyes.  Blindness can occur.\n\nOn the bright side, without sunlight we would all die by freezing to death.  If we could somehow survive that, we would then all die because without the sun, plants could not take carbon dioxide out of the air and create oxygen for us to breathe.  Sunlight is also needed in the production of vitamin D in our bodies.  Strangely, vitamin D helps against overproduction of cells, which is cancer!\n\nSunlight can both create AND prevent cancer!  You gotta love our sun!

i do, and i actually went to the eye doctor today.  he said it isnt good because the solution has preservatives in it that arent made to be in your eye at all times.  like if you put your contact in and it has some solution, your eye washes that away after a few minutes.  the answer is no

That's because Septra is an antibiotic that can make you more sensitive to sunlight.  That means that you're more likely to get a sunburn or a photoreaction wherein your skin burns more easily than you normally would.

Dear hot ...\n\nI do that, too.\nI have always wondered why.\n\nI once heard someone say it has to do with the way the light affects your optical nerve.

The sun 'burns' hydrogen and turns it into helium and lots and lots of light and heat and other kinds of radiation. It's a giant unshielded nuclear fusion reactor, and it's only 93,000,000 miles away...don't forget your sunscreen.
