The Anatomy of the Compound Eye

The Anatomy of the Compound Eye

The “pixels” of a compound eye are called ommatidia.

Each has a lens system that focusses light on a dense column of microvilli, called a rhabdom.

The microvilli contain photo-sensitive molecules.

Eight photoreceptors in each ommatidium contribute microvilli to the rhabdom.

They are surrounded by a pigment cell screen.
