What is color blindness?
Color blindness occurs when problems with the eye's color-sensing pigments make color differentiation difficult or impossible. Most colorblind individuals cannot tell the difference between red and green. While this color blindness is less prevalent, differentiating yellows and blues can be difficult. The severity of the condition varies. You can only see in monochrome or black and white if you are entirely colorblind, a condition called achromatopsia. This syndrome, however, is quite uncommon. Most individuals with color blindness see the following colors on color charts rather than the reds, greens, and teals that others can see- yellow
- Grey
- Beige
- Blue
What are the types of color blindness?
There are three types of color blindness:
Protanopia:
People with protanopia have difficulty distinguishing between red and green colors. It is because they have an absence or a malfunction of the red cone cells in their eyes.Deuteranopia:
People with deuteranopia have difficulty distinguishing between red and green colors. It is because they have an absence or a malfunction of the green cone cells in their eyes.Tritanopia:
People with tritanopia have difficulty distinguishing between blue and yellow colors. It is because they have an absence or a malfunction of the blue cone cells in their eyes. It's important to note that color blindness can range from mild to severe and affect each person differently. Additionally, some people may have a combination of these types of color blindness. The most common form of color blindness is red-green color blindness, which affects about 8% of men and 0.5% of women of Northern European descent.
