Why do animals eyes light up in certain colours when shone at with a torch/light?
Many especialy night active animals have a layer of reflective tissue behind the light sensing cells at the back of the eye. That allows them to caputer more light in their light sensing cells. Additionaly that makes the eyes act as a retroreflector (meaning they will reflect light back paralell …
The Short Answer
Many especialy night active animals have a layer of reflective tissue behind the light sensing cells at the back of the eye. That allows them to caputer more light in their light sensing cells. Additionaly that makes the eyes act as a retroreflector (meaning they will reflect light back paralell to the incomming light) like in the bottom image here: _URL_0_ . The color comes from the tissue that surrounds the lightsensing cells absorbing some of the light.
