I saw a lof of warning screen from video games with that flashing effect thing, why is it dangerous? And how harmful will it be for anyone with epilepsy if they keep playing games with those effects days by days?

Photosensitive epilepsy can be triggered by any flashing lights. Games. Movies. A strobe light of any kind, really, is a risk to epileptics due to it being one of many potential triggers for seizing.

(Seizing, otherwise known as epileptic fits, comes in various forms of varying degrees of intensity and can be triggered by anything from high stress to flashing lights).

Edit: Also, it might not even take days. Depending on the form of epilepsy flashing lights will potentially pose an immediate danger.

the processing of light/dark contrast can cause misfires. enough of them or the frequency or both can cause the brain to “freak out” for lack of a better term and seize. I’m a third and my son is a fourth generational epileptic in our family.

There are some games I can play that he can’t and visa verse. I could play Diablo 2, he couldn’t because of the lightening effect. He can play D3, I can’t because of the hit box flash on mobs.

I went back to Atari games for fun and I swear I have no idea how I’m still alive.

One of the tests for activity and sensitivity is resting in a dark room while being “hit” with different frequency and intensity of flashing light.

Other common triggers are stress, lack of nutrition and sleep deprivation while some less common are smells, noises and fast motion which categorizes with blinking/flashing light or stark, repetitive contrast change.
