Is there a way to limit vision?

I want to create a custom character that has limited vision  if he doesn't have glasses equipped. Is there a way to make part of the screen darker, even during the day?

Probably. All you'd need to do is have an overlay, of sorts. Like the bloodover effect you get when you get hurt. I'd show you but I don't know how to do it.
