1. To isolate the blue cones of the normal eye, blue sine-wave gratings were superimposed on a bright yellow background. Threshold contrasts for resolution of the gratings were then determined.2. Under these conditions visual acuity for high contrast gratings on four normal subjects was on the average 0.31 min(-1). This is about a factor of 6 lower than grating acuity under optimal conditions.3. The contrast sensitivity of two subjects who lack the normal red and green receptor mechanisms was… CONTINUE READING
