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.
I immediately thought about that, my first go at it started with a big glitchy rapidly-flashing ball right in the middle of the screen. (Not sure if it should be like that? iOS safari, iOS16.0) Kind of the worst case scenario.
This just gave me an idea for a browser extension.
How would that work?
The screen would flash anytime you clicked with your mouse.
and also whenever you least expect it
And a mute button.
