New Why Do Animals Eyes Glow In The Dark
Pics. However, to know why they glow in the dark, we need to take a general look at vision in cats. The reason cats can see is because light reflects off objects into the cornea of their eye.

Cat with glowing eyes, mattes, wikimedia commons although cats' eyes appear to glow in the dark, they are actually reflecting ambient light due to a reflective surface behind their retinas called the tapetum lucidum. I was so impressed by how many kids were able to figure out why the pupil changes and make good predictions about why eyes glow. Humans don't, and neither do some other primates.
Often the eyes give off a glow at night that is easily recognizable.
After doing so, it crosses the pupil and iris which increase or decrease in size according to the amount of light passing through. The red eye that shows up in flash photography, usually when you are trying to preserve memories of sentimental family moments, is a reflection of the light off the blood vessels contained in the human retina. This layer of tissue does not dissipate after death, so an animals eyes will still reflect the light after it died. Why do cat's eyes glow different colors?
