Compound eyes are composed of a great number of facets. Below each facet is an individual light gathering structure called an Ommatidium. The facet on an ommatidium acts as a cornea. Like our own cornea this serves to focus the light. The focused beam moves through a crystalline matrix and shines on Retinula Cells which convert it to an electrical impulse. This impulse can be carried to the brain for interpretation. The brain is able to put all these tiny pictures together into a mosaic. While a compound eye cannot register the fine detail of our own eyes, it is particularly good at detecting and following motion.
