When an animal's eyes are positioned on the sides of its head, this is called monocular vision. This gives the animal the ability to see two objects at once. It is seen in animal species that tend to be prey of other species.Monocular vision is different from binocular vision, in which the eyes are positioned on the front if the head. Binocular vision is seen in predatory species, as it gives these animals greater depth perception and better ability to track their prey.

Butterflies and bees have the best color vision, they can see even ultraviolet colors (and even we can't see those!)
They are generally positioned to allow an animal to see as much of the area round it as possible - this can only be achieved if they are set apart. In predatory species this all round vision is restricted to forward vision where the eye spacing allows for stereoscopic vision enabling the animal to judge distances very well.
They need it find prey or hide from predator's.
The vision tester is just another type of furniture you can put in your house. It has no special purpose, as you cannot do anything with it.
