Abstract

Lateral chromatic aberration was measured in the right eyes of four adult observers as the physical misalignment between perceptually aligned short-and long-wavelength targets. The magnitude of aberration generally increased with retinal eccentricity but remained less than 10arcmin within 40 deg of the fovea. At 60 deg, lateral chromatic aberration increased to approximately 30 arcmin but was reducible by refractive correction in the two observers retested. The results are consistent with previous reports of a sizable region of reasonably good optical quality extending into the retinal midperiphery. Within this region, lateral chromatic aberration approximates the average spacing between adjacent retinal cones, indicating that it does not substantially limit peripheral color vision.

Differences in physical misalignment of perceptually aligned targets under heterochromatic conditions as a function of retinal eccentricity. The data represent lateral chromatic aberration corrected for constant errors. Positive values indicate misalignments to the right, and negative values indicate misalignments to the left. All subjects showed the reverse of expected direction of lateral chromatic aberration at the fovea. Data in the nasal retina are for four subjects. Data in the temporal retina are for three subjects. Symbols for subjects: squares, MH; circles, MJ; upright triangles, UO; inverted triangles, JV. Open and filled symbols represent measurements without and with refractive correction, respectively. Dashed line is the predicted amount of lateral chromatic aberration on a computer-simulated wide-angle model eye with the axial point taken to be at 5-deg nasal retina.

Retinoscopically determined corrections for white light are plotted against retinal eccentricity. Separate corrections are provided for vertical and horizontal meridians (open and filled symbols, respectively) to illustrate extent of astigmatism observed with retinal eccentricity. Individual subjects’ data are represented by same symbols as in Fig. 2.

Group-mean data for lateral chromatic aberration (solid lines) are compared with spatial visual parameters (dashed lines). Filled circles represent group means for the temporal retina. Open circles represent group means for the nasal retina. Lower dashed line shows average intercone spacing, adapted from Ref. 37. Upper dashed line shows receptive-field size increase with retinal eccentricity, adapted from microelectrode data.36
