COMPUTER-GENERATED SCREENING TEST FOR COLORBLINDNESS.

Two new technique that test color vision using motion stimuli have allowed us to exploit optokinetic nystagmus as a response measure. We are now able to screen for colorvision deficits in adults and in nonverbal infants by observing their eyes as they watch a computer-controlled TV display. It was shown that the relative contribution of red and green cones to the luminance channels is already in place within the first few months of life.
