To explain: The presence of light-reflecting material in eyes of nocturnal carnivores maximizes the degree to which light excites photoreceptors and also causes the perceived image to be blurred.
Introduction: Nocturnal animals refer to animals that are awake and active during the night. They have good night vision, keen senses of smell, touch, and hearing. They consist of a layer of cells tapetum lucidum behind their retina. It reflects light back through the eye. This enables them to see in dim light or dark.
