Colour-blindness is a condition that is often mistaken and not understood properly. In my blog I will talk about colour-blindness and the specific geography of it. Are certain areas more linked to this disability than others?
Colour-blindness in the Northern European region is commonly divided by gender. Typically, 8% of males will be affected while only 0.5% of females are. This is due to the hereditary nature of the condition. The genes responsible for Colour Vision Deficiency (CVD) are found on the X chromosome which is why men are more susceptible.
Colour-blindness is split into three categories. Protanomaly is a reduced sensitivity to red light. Deuteranomaly likewise, is reduced sensitivity to green light and tritanomaly is related to blue light. Typically deuteranomaly is the most common form of the condition.
It is estimated that 1 in 40,000 people worldwide are born with achromatopsia. This can either be complete or incomplete version. If complete, the person will have no vision of colour at all, but just see in black, grey and white.
All of these variants of this condition are supposed to vary depending on the region and other local factors. That is what I will be talking about.
