How long can you stare at the sun before your eyes get damaged?

It is safer to look at the sun during total eclipse than directly at it. The trouble is you look at it longer and there is where the trouble is.  It is NEVER safe to look at the sun anytime, except indirectly.

This depends on what you mean by the question.  If the Sun suddenly stopped shining, there would be a delay of some 500 seconds, or 8 minutes and 20 seconds, before the effect would be noticed.\n\nIf the Sun's fusion reactions were suddenly stopped, it would take millions of years for the Sun to cool.  Exactly how long it would take for the outside to stop shining depends on a lot of factors, including how well heat is transported between the inside and the surface, but estimates I've seen are around a few hundred thousand years before the Sun is visibly different.  If the Sun's nuclear furnace turned off tomorrow, measurement of sunlight would not detect that fact for many thousands of years.

I've heard that blue eyes are more sensitive to sunlight than other colors.  I would also imagine that sunlight can do at least some damage to eyesight, otherwise we wouldn't need UV-protection sun glasses

Try to take at least six hours of sleep in a day and in addition before going to bed massage your both eyes at the same time for 10-15 minutes with a mild cold slices of cucumber. This will relax your eyes and at the same time will initiate the process to cure the bagginess and darkness of your undereye areas. You will see the results in one week.

Slap yourself pretty hard where you think you are sunburned. If it hurts so band you fall to the floor then you have sunburn. Hey, it's works.

close your eyes for at least 15 minutes, go to an eye Doctor and see if you damaged your eyes, and don't do it again.

well if you dont have sensitive skin i would say no longer than 15 minutes tops! if you have very fair/ light skin that is sensitive I would say no longer than 8-10 minutes it can be painful if you burn! and be sure to use tanning lotions the can help prevent burning

it depends on the fine partcles of water through which the light rays pass.if the condition is simulated it can remain for quite some time.

No that will not cause astigmatism. lol    It is common for blood vessels to break with intense straining as in vomiting, constipation, etc.  No teatment makes it look or get better except time. It takes 2-3 weeks for the redness to resolve completely.

Here's a good rule of thumb:  if prolonged exposure doesn't give you a sunburn, the UV light probably isn't going to damage your eyes.

The intensity of the light burns your retina.

You are never supposed to stare directly at an eclipse.  It can hurt your eyes.  Most site I have seen it can make you go blind. Other sites said differently.

Give your eyes some time to heal!!! LASIK isn't like getting a freaking haircut. LASIK is a surgery and it can take up to 6 months to get your best vision. Also, don't expect your eyes to heal at the same rate. Each eye will heal independently and most patients notice one eye is always better than the other. Also normal.Just remember, no one walks around with only one eye opened.

It's not visible at any time, because from September 23 – October 22, the sun is in it, so you can't see it.  Your best chances of seeing it are in the early evening about four months before then, around June or July.

it can put extra strain on your eyes trying to look at a screen. but if you have pleny of lights on and can clearly see whats on the screen it should be alright. another thing that could end up hurting your eyes is keeping them open too long while staring. eyes will get overly dry and over time that can lead to more serious eye sight problems. keep good care of your eyes.. there the only ones you got!

I would see a derm. and see what they say.   I had some really bad sun damage on my face once and it scarred me up and the dr. gave me retin-a which improved the scars so much they are hardly even visible.    It took about 4 months of this to see a difference.
