Retina: layer of visual receptors covering the back surface of the eyeball d. v.

Accommodation of the lens: adjust the focus of the lens for objects at different distances d. vii. Fovea: central area of the human retina; adapted for detailed vision; greatest density of receptors and more of the cerebral cortex is devoted to analyzing input from the fovea than input from other areas: vision disorders e. i.
