The feline pupil can open about three times as wide as the human pupil, thus letting in as much light as possible at the hunting times of dawn and dusk. The feline eye also has about three times the number of rods (the receptors that are sensitive to light) than we have.

But just letting more light into the eye is not enough--the cat's eye also has a special reflective layer at the back called the tapetum ludium that reflects light not absorbed by the retina when it first enters the eye, and gives it a second chance to be interpreted.

These two adaptations of the feline eye make the cat's night vision 40-50 percent better than ours. They also mean that when the cat's eye is illuminated by a camera flash or by a car headlight at night the eye glows fluorescent when the light bounces off the reflective area. The principle is put to good use in the reflective studs used on roads to show motorists the way at night (actually sometimes called "cats' eyes")
