The reflective tapetum lucidum is responsible for the glowing eye effect seen in photographs.
Tigers have night vision estimated to be about six times better than that of humans. A reflective layer behind the retina called the tapetum lucidum amplifies available light. In dense rainforest at night, this adaptation turns near-total darkness into navigable terrain. Their pupils also dilate widely, maximizing light intake. This advantage allows them to hunt crepuscular and nocturnal prey effectively. When humans require artificial light, tigers operate in natural shadow. Darkness becomes their strategic ally.

For prey species, night offers little safety. The predator’s enhanced vision eliminates the advantage of low visibility. Combined with stealth and explosive speed, nocturnal hunts become highly efficient. This sensory superiority reflects millions of years of evolutionary refinement.
Yet artificial lighting from roads and settlements alters nocturnal behavior patterns. Prey may shift activity, disrupting predator-prey balance. Expanding human presence compresses dark zones essential for tiger hunting success. The erosion of true darkness threatens a sensory system optimized for night dominance.
