I was wondering, I have heard that watching a blinking light can give you a head ack and a seizure. Why does that happen because our computer screens and tvs, are just blinking lights. They blink at about 60-80 times a second.

Blinking lights don't give you seizures, but they can INDUCE a seizure in someone with a pre-existing seizure disorder.

They can also hurt your eyes, but I'm not exactly sure why. It could be due to persistence of vision and your brain's attempt to deal with the fast oscillation. And it is frequency dependent, and different from person to person, so not everyon experiences it with computer monitors.
