I believe the actual terminology for this is called "persistance of vision"\n\nIn loose terms, it's very much like when you stare at the black dot on the green apple for 15 seconds, then close your eyes, then with your eyes closed you see a white spot and a red apple.\n\nsee : http://en.wikipedia.org/wiki/Persistence_of_vision

its a beleif that its a bad omen when the left eye jups but its just a belief. In reality there is no such reason it actually happens due to nervousness or weakness.

I don't think so. I also had the PRK (the one that hurts so much) last summer and now I still do my high school sports like crosscountry, track and tennis. I'm feeling fine and after the many check ups, they say that you can do anything you want like reading, watching tv, and exercise. I don't think it will be harmful to the eyes at all.

It can be very freaky when this happens. I suffer from it myself sometimes when I am stressed or tired. There is no cure that I know of that will get rid of it. but I find if I gently rub the area it calms down after a while.\nBasically it is just a muscle spasm. We get it sometimes in other parts of the body all the time but don't necessarliy notice. \nTo put your mind totally at ease, pop to your local optician. They will be able to check the health of not just your eye but your blood pressure and other health issues too.............. unbelievable but true. The eyes tell us so much!!\nIt may be that you have slight eye strain too. You may need to have a pair of low prescription glasses which will aid your vision and take the stress from your eyes. \nHave a couple of days away from the computer if you can. or make sure you take lots of breaks away from it. This can sometimes cause slight strain if you are sat too close or for a long period of time.\n\nGood luck

Yes, they can actually droop enough to impair vision.  If this happens, it can be surgically corrected.

Yes, there is an operation in which they detach and reattach the muscles that move the eye. It is a very simple and quite common procedure, however you may have a type of lazy eye that is more akin to epilepsy and this is brought on by stress or fatigue. The operation is probably covered by most health insurance.

I'm not quite sure but of course, droopy eyelids can definitely occlude some part of your vision.

I swear I saw a guy take his eyeball, still attached, out of it's socket, then put it back in. I would not reccomend it though, as if you mess up your retina, your eyesight is gone in that eye.

Actually it's not good for you as excessive rubbing with too much pressure can cause your eyeball to change it's shape resulting in vision problems (even just a slight change in the shape can cause this).  Why do some people's brains make drugs, alcohol, or cigarettes feel good?  Not real sure there is an answer for that.  My guess, because we as human beings naturally tend to like things that aren't all that good for us.  Especially when we know it isn't good for us.  LOL.  Or it could be that rubbing them causes your eyes to produce more tears thus clearing debris (bacteria, dirt, etc) that is irritating the eye out of the eye.  Just a guess.\nOh and your eyes have a natural defense against most bacteria/fungi that would get into your eyes (tears, which are used to flush these things as well as others from your eyes.  If I"m not mistaken your tears are slightly acidic which kills a lot of organisms that would get into your eyes.  I might be wrong on that though, they might be slightly basic.  Whatever, the pH level of your tears has something to do with it)  That said, it is a good idea to wash your hands before touching your eyes or any other part of your face.

Wow. I don't believe someone asked this.\nMy ex-husband had this problem everytime he went outside.\nIt was years before a doctor didn't look at him like he was nuts and gave him a real answer.\n\nApparently there is a nerve that runs across the bridge of the nose.  In most people it is located such that there is no problem.  In other people the nerve is only millimeters in a different location.\n\nWhen he went out into the sun the squinting of his eyes due to the sudden increase in light irritated that nerve and caused a sneeze reaction.\n\nHope that helps.  My ex is still nuts, but that's another story! lol

Yes, it's absolutely possible and there are several causes.  One main group of causes could be overaction of your lacrimal (tear) glands.  Another could be that your tears aren't draining properly (maybe due to obstruction in your tear ducts).  If this has become a problem for you, you really should see an eye doctor to find out what the cause of it is and what can be done about it.

First of all, eye color can change with age. Second, it's more complicated that the simple brown / blue description that they give in high school biology class. So I suspect that the answer is yes.
