Vision

Human vision like that of other primates has evolved in an arboreal environment.In the densecomplex world of a tropical forest, it is more important to see well than to develop an acutesense of smell. In the course of evolution members of the primate line have acquired largeeyes while the snout has shrunk to give the eye an unimpeded view. Of mammals only humansand some primates enjoy color vision.The red flag is black to the bull. Horses live in amonochrome world. Light visible to human eyes however occupies only a very narrow band inthe whole electromagnetic spectrum.Ultraviolet rays are invisible to humans though ants andhoneybees are sensitive to them. Humans have no direct perception of infrared rays unlikethe rattlesnake which has receptors tuned into wavelengths longer than 0.7 micron. The worldwould look eerily different if human eyes were sensitive to infrared radiation.Then instead ofthe darkness of night, we would be able to move easily in a strange shadowless world whereobjects glowed with varying degrees of intensity. But human eyes excel in other ways. Theyare in fact remarkably discerning in color gradation. The color sensitivity of normal humanvision is rarely surpassed even by sophisticated technical devices.
