Fly's eye. Coloured scanning electron micrograph (SEM) of a fly's (order Diptera) compound eye. The eye is made up of numerous visual units,known as ommatidia. Each ommatidium consists of an outer cuticle covering a lens,beneath which is a group of light-sensitive cells known as the retinula. Nerve fibres from the retinula converge onto the optic nerve,relaying visual signals to the brain. The image seen by a fly is thought to be a mosaic image,poorly focused but good at detecting movements | |
