The sight of the tiger is during the day similar to the human one but tendentially better. If one carries out the same arrangement for sight at night, one already receives very other results. However, that ought nobody seriously surprises. The sight of the tiger is at night as good about 6 times as that of the human being. These effect lets itself at the inner one with a peculiarity the tiger's eye explain. A brightly reflecting cell shift is meant it is (tapetum lucidum) that in the vein skin Aug imbedded and the light, which one already the net head happened has on, it flings back on itself. The light becomes diffuse through this effect, in the direction of the sending object back, scattered and made the background luminescence of the reflectors known us that we also know of house cats. This is to be observed of course at night only directly, there during day this diffuse luminescence, by the high light potential of the environment, is covered although it is also it there available.

In addition to this fact, the so-called darkness adaptation must also be addressed. A pigment by the name of rhodopsin is responsible for the sensitivity to light of the rod-shaped cells in mind. The organism is without vitamin A to but not to produce it ably, what a night-blindness involves in the case of vitamin A-lack.

The eye of the tiger contains more rod-shaped cells than pegs. That why is indeed very well the basis a tiger bright-dark-differences can recognize but the spectral color sight not all of so well developed is. DA itself the "Fovea centralis" they are for instance in the middle of the visual field is also sight sharp only in this middle is possible (it applies to every mammalia).

Considered objectively is to be localized more importantly it also a booty animal, in addition to the distance appraisal, also in the case of darkness as the color the skin or its review to recognize!!!
