Blocks unfocused : Squinting cuts out some of the light that is not properly focused on the retina. It might cause wrinkles, but it won't hurt your vision. Your vision may degrade over time due to age, not due to squinting.

Changing eyeball: The maneuver compresses the eyeball some and lengthens the distance between the eye lens and the focus spot in the back.This is a simple way to improve nearsightedness. A better choice would be a proper eye exam and glasses if needed.

I agree, and a "pinhole" effect with squinting helps to see better by eliminating the peripheral defocused rays of light thereby allowing the more central rays to focus more clearly on the retina.

Pinhole effect: If you are nearsighted squinting will cause a pinhole effect, which will allow you to focus on light rays that pass directly through the center of the cornea and lens, thus eliminating some of the light rays that are not in focus on your retina. You might need a thin pair of glasses for your best vision, especially for driving at night.

Narrowing the pictur: By squinting you narrow the picture to a finer point.When you look with an open eye you are looking at a wider picture.So it is due to decrease focal area you are looking through.This is done to compensate for vision problem, glasses will help.
