Can you blur your vision on command or do anything else somewhat unusual?

By “on command” I mean literally just make your vision blurry, like you’re pulling a muscle in eyes or something to make it do that. I can do this and for some reason it feels easier to visually convey emotions, like finding a blind kitten and removing all the gross stuff that’s preventing them from seeing. It does not hurt in any way and I’ve been doing it for years so there’s no need to worry. All I’m doing is basically censoring what I can see. It’s kind of hard to describe how it feels though. The feeling is distinct yet very subtle, similar to when you can sense something is wrong but you don’t know what. This also helps me to distinguish colors.
