The tapetum lucidum (Latin: "bright tapestry", plural tapeta lucida) is a layer of tissue in the eye of many vertebrate animals. It lies immediately behind the retina. It reflects visible light back through the retina, increasing the light available to the photoreceptors. This improves vision in low-light conditions, but can cause the perceived image to be blurry from the interference of the reflected light. The tapetum lucidum contributes to the superior night vision of some animals. Many of these animals are nocturnal, especially carnivores that hunt their prey at night, while others are deep sea animals. Despite it being present in some primates, the human eye has no tapetum lucidum, hence no eyeshine. Read Less
