Hi, I don't know what this is supposed to do, but I get pretty bad migraines and loading the page made me feel extremely strange almost immediately so I closed it.

I would check to make sure this can't trigger migraines or seizures. Maybe it's just me, but also, please double check.

Its supposed to show you how big of a radius your eye can focus on at a time, as we age the radius shrinks.

Edit: seems like there isn't enough research to suggest the latter. Apologies
