Can compound eyes see detail?

Resolution: Not every aspect of compound eyes is superior to our vision. While humans can make out tiny details, insects' resolving power is small by comparison. Details get lost even if they are close up, and the world is mostly perceived in outlines.

What is the disadvantage of compound eyes?

Compound eyes generally have only a short range of detail vision. They are very near-sighted, and can see clearly only a few millimeters in front of them with any degree of fine resolution. On the other hand, the near-sightedness of insects is so extreme that they can see detail where we would need a microscope to see.

What is the difference between superposition and apposition compound eyes?

occurrence in insects This is called an apposition eye. In the eyes of insects that fly at night or in twilight, however, the pigment can be withdrawn so that light received from neighbouring facets overlaps to some extent. This is called a superposition eye.
