Why do people squint their eyes when they can't see? Wouldn't that just make it less space to see out of?

Actually no, here is a very good example....\n\nFocus on something across the room......\nNow, take a piece of paper and poke a very tiny pin hole in it and look through the pin hole and the same object.\n\nEverything will be much clearer.\n\nIt's kind of how old telescopes and spyglasses worked.

They've seen something they shouldn't have seen and they can no longer close their eyes.  I know what you mean, it's scary isn't it!

they mostly do that so they don't have to look at the crowd, coaches, or opponent.  It helps them regain and focus, if they were looking around they may loose their composure or get looks of disappointment.

I am amused by your question.  I don't think this is always the case for all people. Some religions can enlighten people too and can bring about additional awareness of their everyday environment rather than produce ...THE FOG. lol\n\nPersonally, I'd rather get through the day with my eyes open. You don't always see everything you'd like to but it's better than not experiencing any of it!

Its something to do with the eyes I think. Sorry I cant give any further info.

well at night, your other senses arent as useful as your sight so. at night your eye sight doesnt get better but when it looks at movement it reacts with a more exagerrated appearance

Well fist off what the lens(glasses) does it help direct the light rays, so they can fall on the retina.\n\nIn "nearsightedness", the rays fall short of the retina (back of the eye where theres cones and rods-that helf see lights and colors). So nearshighted people need glasss that will help to make the rays so "CONCAVE" lens are used these help direct the rays to directly to the retina, these lens .\nNearshighted people either have eye balls that are to long or there eye ball lens is to fat (convex), so they only see near objects clearly. the light rays are nneded to be spread out befor they reach the eye the glasse dos this.\n\n\nFarsightedness- persons only see far objects clarely but not nar objects, this is because there eye ball is to short of there eyeball lens are to thin(concave)  (use diagram lins bellow)\nSo the ray incoming are needed to fucos on the retina, So CONVEX lenses bring these rays toger so thay can fall on the retina

actually not wearing your glasses will make your eye sight worse. My friend started out with a slight vision problem but because she thought wearing glasses was dumb she put it off for years, now she can't see ten feet in front of her with out wearing her glasses, how cool is that? Go to the doctor he will be able to tell you if it is from fatigue or an actual problem.

u see darkness because light isn't present. Not whether is it possible to look at nothing.

Squinting serves two purposes: it improves eyesight by defining objects that are out of focus, and it cuts down on brightness from sources of glare, however, squinting halves the normal number of times a person blinks per minute, which could lead to  eye strain, irritation, tearing and an irritating but treatable condition called dry eye.

So they can see more clearly to answer silly questions

Must be the perspective. They should actually look smaller (further away) because of the extra distance the light travels from the muscles to the mirror to your eyes.

because they want their eyes to be bigger and not so tight!!

Your eyes will NOT pop out!  It is simply a protective reflex.  There is so much going on: abdominal contraction, sharp burst of air from the lungs, lunging movement that the body closes the eyes automatically to protect them.

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

Squint, like you squint with ur eyes? Do u wear glasses? Alot of people who can't see well will squint. Only laser surgery can correct a vision problem if u don't want to wear glasses or contacts.
