The Lucidum tapetum is a layer of tissue at the back of the eye of many animal vertebrates. retina it reflects visible light back through the retina, increasing the light available to the photoreceptors, The tapetum lucidum contributes to the superior night vision of some animals. Similar adaptations occur in some species of spiders, although these are not the result of a tapetum lucidum. Most primates, including humans, lack a tapetum lucidum, and compensate for this by perceptive recognition methods.
