Age-related changes of color visual acuity in normal eyes.

ABSTRACT:

Purpose

To evaluate the age-related change in color visual acuity (CVA) in normal eyes.

Methods

In total, 162 normal eyes (162 subjects, women: 52, men: 110, age range: 15-68 years) with best-corrected visual acuity (BCVA) ≥20/13 were enrolled. Fifteen colors from the New Color Test (chroma 6) were applied to Landolt "C" rings, white point D65 was applied as background, and a luminance of 30 cd/m2 was set for both the rings and the background. These rings were used to measure the chromatic spatial discrimination acuity as the CVA value, while changing the stimulus size. Correlations of the CVA value of each color and age were evaluated. Mean CVA values of all 15 colors (logarithm of the minimum angle of resolution) were compared between age groups in 10-year increments.
