why do animals have eye shine
Answer by Niko Bruchev. Confidence votes 11. Some animal's eyes shine in the dark because of the presence of the tapetum lucidum* in the choroid layer (the middle layer) of the eye. This layer helps to reflect light, presumably allowing them to see better in the dark.This is why most animals which could be considered nocturnal have noticeably shinier eyes than, for example, humans, who do not have any evidence of the tapetum lucidum* in their choroid layer.his layer helps to reflect light, presumably allowing them to see better in the dark.
