Hypertelorism is an abnormally increased distance between two organs or bodily parts, usually referring to an increased distance between the orbits (eyes), or orbital hypertelorism. In this condition the distance between the inner eye corners as well as the distance between the pupils is greater than normal.
The eyes of an animal with monocular vision are positioned on opposite sides of the animal's head, giving it the ability to see two objects at once. This is usually most commonly seen with prey animals, as the reason why their eyes are placed on either side of their head is to make it easier for them to look out for predators, which usually ...
In animals with forward-facing eyes, the eyes usually move together. The grey crowned crane, an animal that has laterally-placed eyes which can also face forward. Eye movements are either conjunctive (in the same direction), version eye movements, usually described by their type: saccades or smooth pursuit (also nystagmus and vestibulo-ocular ...
Nocturnal animals (for example, tarsiers) and animals that live in open landscapes have larger eyes. The vision of forest animals is not so sharp, and in burrowing underground species (moles, gophers, zokors), eyes are reduced to a greater extent, in some cases (marsupial moles, mole rats, blind mole), they are even covered by a skin membrane.
They have large triangular compound eyes that are spaced very far apart and have over 4000 individual facets. [8] When light bounces off a highly-reflective layer called the tapetum lucidum at the back of their eyes, it makes them appear to glow. [8]

The eyes are positioned on the top of the head, and the fish floats at the water surface with only the lower half of each eye underwater. The two halves are divided by a band of tissue and the eye has two pupils, connected by part of the iris. The upper half of the eye is adapted for vision in air, the lower half for vision in water.

The angle, or amplitude, of eye movement in chameleons is very large for a vertebrate [1] and the eyes move independently of each other. [2] This allows a chameleon to watch an approaching object while simultaneously scanning the rest of its environment. [1] Chameleon eyes protrude laterally from the head, giving the lizard panoramic sight. [2]
