Heterochromia

Those who have heterochromia are usually born with the disorder. Heterochromia is a mutation which changes the melanin level of each eye, giving you two different colored eyes. A few famous people who have such a mutation include David Bowie, Henry Cavill, Jane Seymour, Robert Downey, Jr., Benedict Cumberbatch, and Kate Bosworth.

A lifetime worth of eyelashes measures HOW MUCH?!

Backwards and Upside Down

The images of which our eyes send directly to our brains are actually sent in the way we don’t think. They are sent backwards and upside down. Although we see everything clearly and the right way up, our brain interprets it the opposite. Freaky.
