If you think you have black eyes, there's a 99.99999% chance you're wrong

Your irises are really very dark brown, which you'll see under bright lights

Truly pitch black eyes are the rarest eye color in the world

It's caused by a rare genetic condition called aniridia, where people are missing the irises of their eyes

It significantly affects their vision, with many aniridia patients being legally blind
