Colour blindness usually involves the inability to distinguish between shades of red and green. The condition is often inherited. Other causes include certain eye diseases and medications. More men than women are affected. Most colour-blind people are able to see things as clearly as other people but are unable to fully ‘see’ red, green or blue light.
HOW IS COLOR BLINDNESS DIAGNOSED?
Ophthalmologists use the Ishihara colour test to diagnose colour blindness. For children who have not yet learnt to read, symbols are used in the Ishihara test. Another test is the Farnsworth-Munsell 100 hue test.
