At least for me, I notice that when I squint, my vision becomes sharper. I don’t know if this is a common thing, but I’m curious as to why it happens
In: Biology
From what I understand, it is redirecting or focusing the light entering your eye to the fovea, the part of your eye, located in the center of the retina in the back of your eye, in which the cones are located. These cones are responsible for differentiating between the colors of light. Because of this, if light is not focused on the fovea, the image you see isn’t as sharp.
Glasses help focus the light on the fovea if your eye is no longer able to fully do this on its own. Squinting does a similar thing, but not the same. When you squint, you limit the light entering your eye to be more centered on the pupil, which means that the light can only enter from a more direct approach. Because the light is entering at a more direct approach, most of the light that is entering your eye is now focused on the fovea, which means you now see a sharper image.
