fovea

fovea (fovea centralis) A shallow depression in the retina of the eye, opposite the lens, that is present in some vertebrates. This area contains a large concentration of cones with only a thin layer of overlying nerves. It is therefore specialized for the perception of colour and sharp intense images. The clarity is enhanced when light is focused on the foveae of both retinas simultaneously. See binocular vision.

fovea (pl. foveae)
1. A small depression or pit.

2. In the retina of most diurnal vertebrates, a shallow depression that contains cones but no rods, and has no blood vessels or layer of nerve fibres between the cones and the incoming light.
