Comparison of the incidence of colour blindness between sections of Libyan and Indian populations.

ABSTRACT

Incidence of Red-Green colour blindness was studied in a Libyan population and was then compared with the same in two samples of Indian population. The incidence of the Red-Green colour defect was found to be 2.209% amongst the males and 0.0% amongst the females in the Libyan study. However, the incidence was only 1.841% amongst the ethnic Libyan males. This incidence was comparable with those reported from other African countries like Congo and Uganda. The incidence of Red-Green colour defect amongst the Indian males was found to be 2.295% while it was 0.840% amongst the Indian females.
