I'm trying to find the name of this particular phenomenon, so I can research it. When I'm looking at things, only a tiny spot is in focus and everything else is blurred. So if I'm reading, I'm only "seeing" a couple of letters at a time. Or if I'm looking at someone, their eyes are in focus and their lips aren't.
Searching for "narrow area of focus" and similar just gives me photography advice or stuff on *mental* focus. Has anyone got a name for it?
