3. The adjustment of the eye for various distances whereby it is able to focus the image of an object on the retina by changing the curvature of the lens.

These three actions constitute the accommodation reflex. The ability of the eye to accommodate decreases with age. Synonym: ocular accommodation; visual accommodation See: illustration
