Similarities and differences between human and compound eyes
Similarity
- both have lenses
- have light sensitive cells allow eye to collect data that is interpreted by brain to form images
Differences
| Character | Human eye | Compound eye |
| Field of view | Narrow | Wide because it covers a big part of the head |
| Number of visual unit | One per eye | Many (omatia) per eye |
| Regulation of light into the cell | Light is regulated by iris | Does not regulate light |
| Visual acuity | High visual acuity due to high density of sensitivity cells in the retina | Low visual acuity due to
(i) low density of light sensitive cells (omatidia) (ii) small lenses leading to high diffraction of light (iii) have small brains that cannot interpret detailed images. |
| Critical flicker frequency | Low | High |
| Color vision | Distinguish between colors | Not all compound eyes can distinguish between colors |
