Why Dog Eyes Glow at Night
Posted by Clare Bristow
Have you ever noticed your dog's eyes glowing at night, and wondered why they do that?
At the back of their eyes dogs have a mirror-like layer of cells called the tapetum lucidum.
The job of the tapetum lucidum is to improve your dogs vision in dim light, and it does this by reflecting light back to the retina.
The more light the retina receives the more information it has to work with to translate that light into images (that's a very simplistic version of how our eyes work!).
So when your dog's eyes are glowing, what you're seeing is light being reflected by the tapetum lucidum.
