Does squinting actually help us see better or is it another brain trick?

In: Biology

It does. Smaller gap allows less light thought which makes it easier for the eyes to focus.

it does help. a smaller aperture on your eyes results in less light, but also in a sharper image as it reduces “spherical abberations”.

you don’t need to squint, you can also make a small home with your fingers.
