They need only about one-sixth of the light needed by humans. Cats’ eyes also have a mirror-like structure called the tapetum lucidum that reflects incoming light, intensifying the excitation of ...

The tapetum lucidum is also useful to fish, dolphins and other aquatic animals, because it helps them see better in murky, dark water.

The tapetum lucidum is a reflective membrane located behind the retina. It reflects visible light that has already passed through the retina, sending it back through the retina a second time.

The blue tapetum lucidum of a reindeer is optimized to selectively reflect blue and UV light onto the retina, helping the reindeer to see better in dim winter conditions.

When the Tapetum lucidum adjusts the increased fluid pressure in the eye, the eye colour changes to blue. This adjustment makes their eyes 100 to 1000 times light sensitive.

So, eyeshine is a visible effect of having a tapetum lucidum. And it’s a useful adaptation that allows animals to see at night or in low-light conditions, enhancing their visual sensitivity by as much ...

The tapetum lucidum is also useful to fish, dolphins and other aquatic animals, because it helps them see better in murky, dark water. In land animals, the tapetum is found in the top half of the eye ...
