So I have a concussion. Was told I probably didnt.

The problem is - my eyesight - the too bright lights. Nobody said "keep off your computer for a few days" And I was too out of it too figure that out myself. So I spent far too much time staring at screens. That's on me. So the brightness continues. Hopefully its not going to last.

My advice is: Whatever you do - stay away from the damn computer for a few days.
