Ommatidia is the structure in the eye of the Limulus that contains a small lens, located directly over a visual receptor. The Limulus eye is made up of hundreds of these Ommatidia. The Limulus eye has been used for research on lateral inhibition because its receptors are large enough so that stimulation can be applied to individual receptors.
