I’ve had bad vision since I was in middle school, but being that young it could have been much earlier without me knowing. I believe I came across this phenomenon when I was trying to read something on the board while in the back of the classroom which is pretty much the only situation it has ever come in handy. I rarely ever do it now that I’m an adult with contacts/glasses, but I’ve never met anyone else that is able. It’s not really a conversation topic so I thought I’d ask my fellow friends in the bad vision club if they are also finger pushers! For reference I’m at and always have had -2.25 in both eyes and was told it came from a big growth spurt.
