why does squinting help us see better?

The lens of your eye is a refractive lens. If you use a camera lens as an analogue, the higher the f-stop (the smaller the aperture), the less spherical aberration. In other words, fewer light rays to scatter. The result is a clearer picture. Squinting may act on the eye in the same manner.
