Is our eye more complex than compound eyes? if so then why does ourr eye detect only 3 colours whereas that of a mantis shrimp detect more than that? |
| Answer» N insect COMPOUND eye has the capability to see color if it contains corresponding sensor cells, most insects can only see light and dark. A few, like bees, see more colors than humans, but they don't have the additional qualities of vividness and shading,e. The visual acuity of compound eyes depends on the number of ommatidia in the eye and their size. For the eyes of vertebrates, visual acuity depends on the DENSITY of light-sensitive cells in the retina. Dragonflies have one of the highest-quality compound eyes with 30,000 lenses per eye. Birds of prey, such as BUZZARDS, have up to 1 million sensor cells per square millimeter. The eyes of these birds have two to three times the acuity of human eyes, but the acuity of a human eye is still about 100 times better than that of the BEST insect compound eye. | |
