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.

It can be reversed by irrigating the eye with hypertonic saline which osmotically draws the excess water out of the eye. When, for example, looking out of the window in a moving train, the eyes can focus on a 'moving' tree for a short moment (through smooth pursuit), until the tree moves out of the field of vision. Cone cells, conversely, need high light intensities to respond and have high visual acuity. night vs. Therefore, for any detailed visually guided tasks on which
The differences are useful; apart from enabling sight in both dim and light conditions, humans have given them further application. Jumping spiders have simple eyes that are so large, supported by an array of other, smaller eyes, that they can get enough visual input to hunt and pounce on their prey.
