The mechanism or process by which the optics of the eye adjust to maintain an image in focus on the retina as the object’s distance from the eye changes. It is the ability to change the focal length of the eye lens. The focal power of the eye is highest during childhood and the young adult years. It gradually declines with age and after the age of 40 the lens nucleus rigidity clinically decreases accommodation. The sclerotic nucleus becomes unable to bulge anteriorly and adjust its anterior curvature as before.
