'Vision through my aging eyes' revisited.

A variety of age-related changes occur in the visual system of older adults who are free from identifiable eye disease. Normal aging of the eye can affect visual functioning in older adults, and a variety of psychophysical tests have documented some of these effects. Dr. Meredith Morgan, a distinguished optometric educator, describes many of these changes in his editorial "Vision Through My Aging Eyes." In this article, an overview of several common anatomical, physiological and psychophysical changes which occur in the eye with normal aging is provided, and specific observations made by Morgan are discussed in terms of this information.
