Based on my understanding of how (some) ancient Greeks understood how vision works. A light is implanted in each eyeball, allowing a beam to be transmitted in order to see in the dark. Not sure about how its powered, or the ramifications of the heat a light will probably generate, or how to turn it on / off. Someone else can figure out that stuff. I just think it would be cool to have beams of light come out of our eyes.-- snarfyguy, Dec 16 2001 Raytracer implant.

He touches a contact on one of his back teeth with his tongue and the outer cells of his retina emit a soft light.
