Tigers' Eyesight

Tigers' Eyesight


The night vision of tigers is six times better than humans.

Like the average house cat, tigers have an adaptation that reflects any light to the retina. This means the night vision of a tiger is quite remarkable and six times better than that of a human.

Called the tapetum lucidum "bright carpet" this reflective layer is located at the back of the eye.

Any light not absorbed by the rods and cones is mirrored back to these eye parts a second time; this allows more light to be absorbed. This, along with a high number of rods, gives many animals the ability to see in very low-light conditions. It does not mean that cats can see any better in total darkness than humans can. There must be a degree of light for this adaptation to work.
