THE HUMAN EYE VS THE COMPOUND EYE
"Visual Acuity- insects only contain 7 to 11 sensory cells and for dragonflies which consist of 30000 ommatidia (which is considered the highest) has only While humans already contains 175000 sensory cells per square meters alone. This allows human eyes to detect greater spatial resolution.
Contrast- In dim light, an optical system needs to collect more light in order to see clearer. In general insects especially those diurnal ones are limited by the small apertures of each ommatidium in the compound eye, hence detect weak contrast especially in bright daylight or dim light. .
Colors- Color vision in humans depends upon the three types of opsins- red, green, blue. Most insects can see ultraviolet and see the plane of polarization of light ."-
