Weird Fact: Statistically, 1 in 12 white men are colorblind.
But that doesn’t mean they view the world like black-and-white TV. There are varying degrees of color deficiency and most people suffer from the weakest form called Deuteranopia.
These people just can’t tell the difference between red and green. So they have to be extra aware of the position of the lights at traffic signals – or risk causing an accident. And if a dichromat were strolling through a lush green forest, the scenery would look a rather bland tan or gray.
So what causes color blindness?
The human eye has red, blue and green cones on the retina at the back of the eye, which makes you sensitive to all the colors of the rainbow. The majority of color blind people don’t have the right combination of cones, usually because of a genetic fault.
This is why color blindness affects more men than women, and why it can be prevalent in small island communities who have a limited gene pool.
How do you know if you’re color blind?
Many people don’t find out until the school nurse gives them this classic color deficiency test:
If you think you may be color blind – don’t worry. Most people have the weakest version of this condition which is easy to cope with once you know about it.
And, remember, you can’t miss what you never had 😉
