Night vision

Night vision is the ability to see in low light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range. Humans have poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum.

Darkness....No Parents

A compound found in many deep-sea dwelling creatures that allows them to see in the dark has been injected into a man's eyes. He showed marked improvement in seeing distance and determining shapes in the dark. Super cool!
