How common is photosensitive epilepsy?

This is when seizures are triggered by certain rates of flashing lights or contrasting light and dark patterns.

Around 1 in 100 people has epilepsy and of these people, around 3% have photosensitive epilepsy. Photosensitive epilepsy is more common in children and young people (up to 5%) and is less commonly diagnosed after the age of 20.

So 3% of 1% is... 3 in 10 000, or 1 in ~3.5k people. That's... much more widespread than I'd suspect.

Common enough.

I wonder if a much better solution than warnings would be something at the OS level analyzing the screen and fading out contrast or something any time it detects flashing patterns that could trigger epilepsy.

iOS has recently added that feature for video sources

I think much more common after one visits this site.
