The photoreceptors of the cockroach consists of a pair of compound eyes at the dorsal surface of the HEAD. Each eye is formed of about 2000 simple eyes called the ommatidia (singular: OMMATIDIUM), through which the cockroach can receive several images of an object. This kind of vision is known as mosaic vision with more sensitivity but less resolution.
