Like a mirror at the back of the eye, the tapetum lucidum reflects light back onto the retina, increasing the light that hits it. The tapetum lucidum, a structure common to animals that hunt after dark, gives cats their superior night vision. Human eyes don't have this layer. A cat's eyes glow thanks to its tapetum lucidum. ... That light-reflecting surface, called the tapetum lucidum, helps animals see better in the dark. When light enters the eye, it's supposed to hit a photoreceptor that transmits the information to the brain, Powell explains A cat's vision is similar to a human who is color blind. They can see shades of blue and green, but reds and pinks can be confusing. ... Night vision — Cats can't see fine detail or rich color, but have a superior ability to see in the dark because of the high number of rods in their retina that are sensitive to dim light The truth is that cats cannot see in absolute darkness any more than we can. However, they are much better adapted than humans for seeing in low levels of light. ... Third, cats have an extra "mirror" layer at the back of the eye behind the retina, which means that the incoming light has two chances to hit the rods,..

The truth is that cats cannot see in absolute darkness any more than we can. However, they are much better adapted than humans for seeing in low levels of light. ... Third, cats have an extra "mirror" layer at the back of the eye behind the retina, which means that the incoming light has two chances to hit the rods,.. Lighter eyes, such as blue or green eyes, have less pigment in the iris, which leaves the iris more translucent and lets more light into the eye. This means that light-eyed people tend to have a slightly better night vision than dark-eyed people..
