Can lights trigger vertigo?
Furthermore, high contrast lighting, broken or malfunctioning lights, and/or visually “busy” environments can also be disorienting and lead to vertigo and other vestibular issues—notably for those who suffer from visual or motion-sensitive vertigo.
Why do blinking lights cause seizures?
Certain patterns of light — flashing bright lights at particular frequencies — synchronize cells within the visual cortex. If the neurons then fire through their networks at too high a level, they can recruit other neurons into a hyper-synchronous discharge. That’s what happens in the brain during a seizure.
