Research Abstract

1. We evaluated the ability of congenitally color-defective persons in discriminating among red, yellow and green traffic lights using LED. We built two traffic light systems. Incandescent light bulbs were housed in one and LEDs in other. The two systems were presented to 5 normal persons and 18 color-defective persons as test subjects. Out of 18 color-defective persons, 11(61.0%)gave false answers both for LED and incandescent lights. The incidence of false answers was greater for red and yellow by LED than by incandescent lamp.
2. We tested the ability to read letters on the tri-LED display of 5 healthy subjects and 51 subjects with congenital color deficiency and compared the results obtained in the subjects with congenital color deficiency for those who passed the Panel D-15 and those who failed. Of the 51 subjects with congenital color deficiency, 46(90.2%)made errors. Those who failed the Panel D-15 made more errors than those who passed it.
3. We tested 51 congenitally color-defective persons regarding the ability to distinguish colors of characters written on the blackboard with color chalks. A total of 37 out of 51 color-defective persons(72.5%) gave false answer.
4. Of the 16 subjects with congenital color deficiency were examined using the large field Panel D-15 (8°and 10°) to evaluate the improvement of color sensitivity with the large field Panel D-15. Of the 16 subjects, 5(31.3%) were improved with the 8° field and 8(50.0%) were improved with the 100 field Panel D-15.
5. We evaluated the ability of subjects with congenital red-green deficiency to distinguish colors of printed objects in the textbooks using of elementary schools. We checked 324 textbooks. The results showed that the congenitally red-green defective pupils might have difficulty in distinguishing some colors of printed objects in the textbooks.
