Does anyones eyes hurt after using the iPad for a long amount of time? My eyes begin to hurt when Ive been using my iPad for a while. I don't know if it has to do with the brightness or what, I've tried to turn down the brightness but it doesn't seem to help too much. Does anyone know how to maybe prevent this? Does an anti-glare screen protector help at all, maybe it has something to do with how glossy the screen is because I know on my mom's laptop I can use it much longer without my eyes beginning to hurt.
