Different kinds of light sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark, while more complex eyes can distinguish shapes and colors. The visual fields of some such complex eyes largely overlap, to allow better depth perception, as in humans; and others are placed so as to minimize the overlap, such as in rabbits and chameleons.

The intensity of light (e. It lets light through without refraction, helps maintain the shape of the eye and suspends the delicate lens. Having two eyes is an added complication, because the brain must point both of them accurately enough that the object of regard falls on the fovea. The differences are useful; apart from enabling sight in both dim and light conditions, humans have given them further application. One form is broken down by the particular EM wavelength
This gives humans a highly detailed central vision, allowing reading, bird watching, or any other task which primarily requires looking at things. The iris, between the lens and the first humour, is a pigmented ring of fibrovascular tissue and muscle fibres. It can be reversed by irrigating the eye with hypertonic saline which osmotically draws the excess water out of the eye.[12][14][15] The choroid contains
