ELI5: Why does squinting help your vision?
gpt
Works like a pinhole camera. Basically, blur happens to things based on distance, if you're looking at something close, far things will be blurred, if you're looking at something far, close things will get blurred. By reducing the area of where light enters your eye, you are squeezing together the light, meaning all the distance info gets smushed, allowing you to see things further away more clearly, this effect is greatly amplified for those that wear glasses (like me).
