Why does squinting your eyes help you focus?

changes the shape of the lens on your eye by letting the eye muscles exert more force.

sorry guys, but its not because your eye changes shape. lol
it has something to do with the amount of light being let in around a certain area. Back around the time glasses were being invented, some guy made glasses that were actually just solid figures with a tiny pinhole in the middle that you would look through and because of that it had a squint effect for your eyes and things "seemed" clearer just like when you squint your eyes. Sorry i didnt look it up, and provided no evidence, but i remember learning about it in this bioligy class.

Because you have astigmatism. Your eye is shaped more like a football and squinting corrects that problem (to a degree). I have almost 20/20 vision when I squint, so I can pass any eye test, but I need glasses otherwise.

Eye need to be focussed for clear vision. The image falls on an area called MACULA of each retina. . The lens in each eye, Iris of both eyes are to adjust to a fixed shape. For that one has to suint.
