A simple eye is one single eye. A compound eye is an eye made up of thousands of little eyes, all seeing the same thing.
A wasp has three simple eyes -- called ocelli -- on the top of its head. These are in addition to the two compound eyes.the compound eyes are the wasp's organs of vision; the ocelli don't form images and help the insect orient while in flight.
Centipedes have simple eyes, also known as ocelli, which are photoreceptor organs that can detect light and dark but do not form images like compound eyes.
A spider eye typically has multiple simple eyes (called ocelli) that can detect light and dark, while a fly eye has complex compound eyes composed of many individual lenses that can detect motion and detail. Spider eyes are more focused on detecting movement and prey, whereas fly eyes are specialized for navigating and avoiding obstacles during flight.
A bee has five eyes – two large compound eyes and three smaller simple eyes. The compound eyes are used for detecting motion, light intensity, and color, while the simple eyes help with orientation and navigation.
