Caption: Fly compound eye lenses, coloured scanning electron micrograph (SEM). A compound eye consists of many rounded lenses known as ommatidia. Each ommatidium is a simple eye that sends a signal to the fly's brain. All the signals are combined by the insect's brain to form a mosaic view of the world. The image seen is not very sharp but good at detecting movements. Between the lenses are hair-like structures called interommatidial bristles (two are seen here, at centre and centre left). Magnification: x1400 when printed at 10 centimetres across.
