Why does squinting (or looking through a small hole) improve your vision?
It's more of a physics question than a biology one, but this is why. When your eye is completely open, there is light coming in from several angles, many, many angles. However, your poor eyes take these angles and mess with them, so your vision goes blurry.
The Short Answer
It's more of a physics question than a biology one, but this is why. When your eye is completely open, there is light coming in from several angles, many, many angles. However, your poor eyes take these angles and mess with them, so your vision goes blurry. When you look through a small hole, then less light is entering your eye at once. As a result, even if the light is being redirected, it's not being scattered or blurred as much, so you can see clearly. Some Youtuber did a great, ELI15 video on it, but unfortunately I cannot find that video.
