Photopic temporal contrast sensitivity for healthy eyes of observers 65 years old and older is compared with retinal-illuminance-matched younger eyes. The are significantly less sensitive frequencies between 10 45 Hz. Although there a slight shift to slower flicker rates in the mean function observers, this trend not statistically significant, suggesting that relatively little loss resolving power visual system aging. These preliminary results from an ongoing study aging
