I know what red eye is. We're not talking about a regular red eye, which is - well, red. I might be wrong, but I've seen ONE red eye pic in this thread. We were talking about a different effect, and it's far from it.

It's the same effect, is what I mean. The reflective effect of the tapetum lucidum is the direct equivalent of red eye. Both can be caused and captured by flash photography.

Yeah, but humans do not possess that substance

Yeah, I know. It's weird that his eyes reflect that color.

Here is an explanation for why Dave's eyes glow I think. It's that weird tapetum thingy... The tapetum lucidum (Latin: "bright carpet") is a reflecting layer immediately behind, and sometimes within, the retina of the eye of many vertebrates (though not humans); it serves to reflect light back to the retina, increasing the quantity of light caught by the retina. This improves vision in low light conditions, but can cause the perceived image to be blurry from the interference of the reflected light. It is therefore primarily found in nocturnal animals with good night vision, such as cats. In various species, the tapetum lucidum is responsible for the equivalent of the red-eye effect in humans. In flash photographs, the eyes frequently appear to be glowing in one of a wide variety of colors including blue, green, yellow and pink. Bottlenose dolphins and dogs also have a tapetum lucidum. The tapetum works roughly on the interference principles of thin-film optics, as seen in other reflective tissues such as butterfly wings (see Blue Morpho). However, different species have different types of structured tissue that lead to different mechanisms of reflective interference (Ollivier 2004). Known tapetum structures include: Retinal tapetum in teleosts, crocodiles, marsupials and fruit bats. Choroidal guanine tapetum in elasmobranchii. Choroidal tapetum cellulosum in carnivores, rodents and cetacea. Choroidal tapetum fibrosum in cows, sheep, goats and horses. en.wikipedia.org/wiki/Tapetum_lucidum

I can't say David is evil, he's human like the rest of us, just because he's got long teeth and striking eyes doesn't mean he's some sort of odd male. I believe the eyeliner makes him look cool.
