Colour Blindness

Colour blindness is a genetic condition. People with this condition have few or no cones in their eyes for recognizing different colours.

Colour blindness is a genetic condition. People with this condition have few or no cones in their eyes for recognizing different colours. The average person has 3 different types of cones for differentiating between red, blue, and green. Depending on which cones you lack, the colours you have trouble distinguishing will vary.


Red-Green Colour Blindness

Red-green colour blindness means just what it sounds like–difficulty seeing red and green colours. Orange, a color that is similar to red, is also difficult to distinguish for people with red-green color blindness.  For those who suffer from this type of color-blindness, blue and yellow stand out more.


Blue-Yellow Colour Blindness

This is a rare type of colour blindness wherein people have trouble telling the difference between blue and green, and yellow and violet. The cones for the colour blue are less sensitive or missing in people who have this disorder.

Complete Colour Blindness

Finally, people with complete colour blindness are missing all the cones in their eyes. They see the world in black, white, and gray. Many people become completely colour blind due to accidents or neurological injuries. However, there are people who inherit an extremely rare genetic disorder that causes their body to not make cones. 

If you think you might be colour blind, it’s a good idea to go see your doctor. He/she will administer tests and determine which type of colour blindness condition you have. And don’t worry if you do have some form of colour blindness. The condition affects 1 in 12 men and 1 in 200 women. So, you’re not alone.
