SUMMARY

Watching blinking lights, such as those from computer screens and TVs, can induce headaches and seizures in individuals with pre-existing seizure disorders. The flickering occurs at frequencies of 60-80 Hz, which may lead to discomfort due to persistence of vision and the brain's response to rapid oscillation. Sensitivity to blinking lights varies among individuals, meaning not everyone experiences adverse effects from computer monitors.

PREREQUISITES
  • Understanding of seizure disorders and their triggers
  • Knowledge of visual perception concepts, particularly persistence of vision
  • Familiarity with screen refresh rates and their impact on visual comfort
  • Basic awareness of neurological responses to visual stimuli
NEXT STEPS
  • Research the effects of screen refresh rates on visual comfort
  • Explore the relationship between flicker frequency and seizure induction
  • Investigate methods to reduce eye strain from blinking lights
  • Learn about the neurological mechanisms behind visual discomfort
USEFUL FOR

Individuals with seizure disorders, eye care professionals, neurologists, and anyone interested in the effects of screen usage on health.

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.
