My 13 year old son has a strange visual disturbance. He says his field of vision brightens for a few seconds then returns to normal, kind of like increasing the brightness on a computer monitor. He also says he has mild headaches. He never complains about them, says they dont really bother him. He thought the visual brightening was normal, like ringing ears so never mentioned it to me before so he's had them for at least a year i believe. THey happen about twice a week. Took him to his pediatrician who found nothing wrong with him, (except his vision is slightly worse than before) so refered us to a pediatric eye specialist. Have an appt in 2 weeks.
He has a little trouble seeing far away so has glasses but rarely uses them. He also plays computer games a lot and the nintendo gameboy. Maybe it's eyestrain? He is also going through a growth spurt. Maybe hormones?
