Like us, Sumatran tigers have forward facing eyes, this allows for binocular vision as each eye's field of vision overlaps, creating a three dimensional image. Binocular vision allows tigers to accurately assess distances and depth which is extremely useful for maneuvering within their complex environment when stalking their prey.

Tigers also have more rods (responsible for visual acuity for shapes) in their eyes than cones (responsible for color vision) to assist with their night vision. The increased number of rods allows them to detect movement of prey in darkness, where color vision would not be possible.

Also assisting their night vision are their tapetum lucidum, a structure at the back of their eyes, behind the retina. This mirrorlike structure reflects light (that has not already been absorbed by the eye) back into the eye a second time to help produce a brighter image. The tapetum lucidum causes their eyes to glow at night, when a light is shone on them.

In general, cats require only about 1-6 the light humans require to see!
