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

You’ll experience trouble seeing things far away in the first place if your iris has trouble closing to focus the light onto your retina. Glasses do this for those of us who have that problem. Squinting sort of replicates what a pinhole camera does, and at the cost of some light not coming in, helps focus the light from the object you’re looking at correctly. You can make some rudimentary ‘glasses’ by taking your index finger and curling it up against your thumb so that just a little bit of light comes through, then look through it. It takes a little practice to get the hole the right size and to find the distance it needs to be from your eye (pretty close though) but that will give the same effect.
