Understanding The Full Spectrum Of Color Blindness

We have found different ways through which an individual can be color blind, and the rarest types of them results in seeing black and white.

When an individual suffers from color blindness, the condition is called monochromacy. The condition is rare, and only one in 33,000 people has it. In most of the cases, the color blindness is for a few colors. Understanding color blindness is a bit complex, and let us take you walk through here.

Read the following and later when you visit your eye specialist in Abu Dhabi, the haze around color blindness will go away.

The basics of color vision


Before you understand color blindness, you need to know how color vision works. One step in this vision process is when the light hits the photoreceptors in our eyes. These receptors are of two types: rods and cones. Rods can distinguish between the amount of light we see, while cones help us detect different colors.

A person with normal color vision will have three types of cones absorbing light from different parts of the spectrum. Blue cone to process short wavelengths, green to process medium wavelengths, and red for long ones.

Color blindness is the result of the mutation of the chromosome. Women have two X-chromosomes, while men have only one. That is why one in a dozen men has this condition but only one in 200 women suffers from the disease.

Types of color blindness

When all the three types of cones are present, the condition is called trichromacy, and this is how the vision is set right. However, it can go wrong when some of the cones misfire, which results in limited vision.

  • Red-green color blindness is the most common, and it happens when the green or red or both the cones misfire.
  • A less common type of color blindness is blue-yellow color blindness, when the relevant cones are missing.
