Is squinting bad

Answer 1

Squinting does not harm your eyesight. Rather, when someone has slightly weakened eyesight, objects will appear slightly out-of-focus. Squinting is a natural response to try to clear vision. Essentially, squinting narrows your field of vision by reducing the area you are looking at, allowing your eyes to focus more clearly on what is still in your vision.

People often think squinting causes bad eyesight, because initial vision damage is very weak, almost unnoticeable, but the body automatically tries to correct it by squinting. By the time damaged has increased to a point where it's noticeable, it may seem to squinting caused the damage, rather than the other way around.
