What is the advantage of monocular vision?
A
provide a narrow field of vision
B
able to form three dimensional image
C
field of vision overlap greatly
D
able to detect enemies coming from any direction
Explanation: 

Detailed explanation-1: -It enables them to respond more quickly upon visually sensing a threat, such as seeing a predator. Monocular vision enables animals to see more than one plane of vision since their eyes works separately. As a result, they can see different objects at the same time.

Detailed explanation-2: -Through the interaction of the two eyes, the binocular visual performance is in certain respects, including acuity and contrast sensitivity, better than monocular, which may be of significance in particular when visual conditions are close to threshold.

Detailed explanation-3: -Monocular visioned animals are generally herbivorous and are prey animals, with their eyes on both the sides of their heads (for 360 degree vision). E.g., lizards, horses, bats, rabbits, small birds, and fish.

Detailed explanation-4: -Monocular cues provide depth information when viewing a scene with one eye. When an observer moves, the apparent relative motion of several stationary objects against a background gives hints about their relative distance.
