Chromatic contrast sensitivity for all 20 subjects as a function of chronological age for (L - M)-varying stimuli. Solid squares represent data from individually adjusted fundamentals conditions, and open circles represent data from standard fundamentals conditions. Data from the four spatial frequencies are plotted in different panels. The dashed line across the bottom of each panel represents a sensitivity corresponding to the maximum contrast achievable for these stimuli under these conditions.
