i know this might not be the right forum to be asking this, but lately I have been trouble reading with both eyes open. my eyes gets tired very easily and the centre of my forehead is red and I keep having to take naps. when i look myself in the mirror it seems magnified as well as perception is off. also when glance at my speedo while i drive, it's a little blurry. sometimes when I walk through shopping aisles, things seem to pass by as they are going too fast. does anyone share this feeling? I've been to optometrist a few times recently but non of them mentioned anything. from my own research, i have uncovered something called convergence insufficiency. does anyone know anything about that?
