The literature regarding aging and visual performance is discussed. A sample population of 102 individuals over the age of 49 completed the Pacific Sports Visual Performance Profile, a test battery which measures several aspects of visual performance. The major purpose of this study was to establish normative data for an older population on clinically measurable visual abilities associated with overall visual function. This test has previously been normed for separate groups of elite athletes and a "non-athletic" population of younger adults. Statistical comparison of the younger adults and the older adults reveal significant differences between the groups for many of the individual tests administered, with the differences being such that the younger adults had higher levels of measured visual performance in every case. Areas of difference included visual sensitivity, accommodation/vergence, depth perception/eye teaming, central visual recognition, central and peripheral response time, eye-hand coordination, anticipation timing, and split attention performance.
