What Do Color Vision Defectives Say About Everyday Tasks?

Re: Is screening for congenital colour vision deficiency in school students worthwhile?

“…After all, a good proportion of people with defective colour vision admit that they have problems distinguishing the colour of signals and seeing brake lights. 4 Likewise with education. While abnormal colour vision is highly unlikely to be a major determinant of educational achievement, there is believable anecdotal evidence it can mystify the colour vision defective school child, when colour is used as a tool of communication in classroom learning.…”

“…Almost all people with abnormal colour vision experience problems with colour in everyday life and it does affect career choice and cause problems at work for nearly 50 per cent of dichromats and about 25 per cent of anomalous trichromats. 4 Ramachandran, Wilson and Wilson 1 concede that people with abnormal colour vision may benefit from knowing they have abnormal colour vision and being given some informed advice on its consequences for them. I am inclined to agree with them that school screening of colour vision may not be the best vehicle for this.…”

Structural and functional correlates in color vision deficiency

“…21 In dichromats, the missing class of cones may be replaced by rods. In anomalous trichromats, the cones are known to be dysfunctional but there is no documentation of structural changes in retina in subjects with CVD.…”

“…The mean age of the cases was 25 years (21-30) and the mean age of controls was 24.4 years (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). The median visual acuity for the fourteen eyes, from seven patients with CVD, used for correlation analysis was logMAR 0 or 20/20 Snellen equivalent.…”
