ELI5: Why squinting appears to improve your vision.
gpt
Because you may have some form of **astigmatism/Farsightedness** (common eye problem) Whats happening is way to much light is entering your eye and your eyes all like *Whooo dude slow down with all this information im not perfect you know!* as a result you tend to get distorted vision. 
When you squint your actually allowing less light or **information** into your eye so your eyes all like *Whoooo brooo i can see this as im only processing a little bit of info, i can totally handle that! But your going to lose things like quality of depth but lets go with it!!* 
I hope this answers your question :)
