This is a fun article but, what if you don't have eyes?

Interesting question. Perhaps there is an alternative way to perform 'Proof of Personhood'. However, any backdoor could ultimately be hacked.

I googled how often it is to be born without eyes, and it It turns out to be more common than I expected; there are approximately 1 in 20,000 cases in live births. This means you'd expected roughly 15,000 individuals in the US alone.
