How is the vision of the compound eye in insects different from human vision?

Compound eyes that are found in arthropods are basically like an array of tiny eyes you and I are used to. Each little "eye" is armed with its own lens, cornea, and photoreceptor cells.
The vision provided by these complex eyes offer a much larger field of vision than humans are used to. They also allow for the eye to notice movement much better.
The disadvantage is that these eyes don't produce much resolution. That is, an insect may see everything with a tremendous amount of detail close up. But just inches away, everything appears as a blur.

∙ 13y agoExcellent question, in most arthropods (generic term is "bugs" but is inaccurate) there is an example of an eye called a "compound eye" which consists of a central point that uses many dozens to thousands of hexagonal interlocking lenses that view the entire scenery around the eye, somewhat like when you put a clear marble at the end of a tube and look at a room. Other arthropods, like most Spiders, use "simple eyes" which are single-lensed eyes, very close in comparison to human eyes, that each register separate information, thus the need for many of them. The only part visible of these eyes is the protective coating, which prevents the actual eye (that moves) from harm. The combination of the two eyes on any given arthropod is extremely rare.

How is the vision of insects and arachnids different?
Most spiders have four pairs of simple eyes, usually grouped into two or three rows, an arrangement that gives them a wide field of vision. Insects have one pair of compound eyes, each made up of individual hexagonal-shaped facets and each facet has its own optic nerve. Their compound eyes allow them to see all around themselves without moving, and this ability makes them very sensitive to seeing any nearby movement.

Will the computer take the place of human vision by 2020?
I dought that computers will ever take place of human vision because if a human can see he doesnt need a computer to do it for him. on the other hand, it is possible that it will inhance vision or cure blindness, but the year cannot be entirely predicted
