Color Blindness: Why Are Men More Likely To Acquire It?

When it comes to color blindness, genetics have been found to play a significant role. Men have also been found to have a higher risk of having it.

Color Blindness Explained

Typically, the human eye is capable of seeing different colors based on various light wavelengths. In the visible spectrum, several colors are present. However, not everyone has the capacity to see colors the same way.

Color blindness refers to a condition wherein a person is unable to see colors in a traditional manner. This is due to the fact that some nerve cells, or cones, in the eyes are missing or do not properly function. People with color blindness may experience difficulties in distinguishing certain shades or colors and perceiving color brightness.

People with a certain degree of color blindness typically experience difficulty seeing greens and reds.

Why Do Men Have a Higher Risk of Color Blindness?

The condition can develop with age or alongside certain conditions. However, in most cases, color blindness is hereditary. Genetics is known to be the most common contributing factor behind color blindness.

The red-green color deficiency gene is typically transferred through the X chromosome.

While males are typically born with one X and one Y chromosome, the red-green color deficiency gene passed through an X chromosome may likely result in a certain degree of color blindness.

On the other hand, females have two X-chromosomes. Hence, this red-green deficiency gene must be present on both X chromosomes from both parents for color blindness to result.

As red-green color blindness is the most prevalent type, the principles of genetics imply that mothers may likely pass the gene to their male children.

Other color blindness forms could be hereditarily passed down. However, other deficiencies, such as blue-yellow color blindness, are linked to chromosomes that are not affected by sex. There are also cases where color blindness could be acquired through different injuries or illnesses over the course of one's life.

Other risk factors for color blindness include multiple sclerosis, diabetes, Alzheimer's disease, glaucoma, retinal detachment, age-related macular degeneration, some medications, including hydroxychloroquine, brain injuries, eye injury or trauma, certain tumors, age, and being white.

Managing Color Blindness

For those born with color blindness, adaptability may not be an issue. Congenital color blindness is determined prior to birth. Hence, in such a case, the eyes' rods and cones do not have the physical capacity to recognize particular colors. This incapacity could be inconvenient or even dangerous.

For instance, traffic lights typically have yellow, green, and red lights. People with color blindness typically learn light positions that signify the "stop" or "go" signal in their area.

In some cases, contact lenses or special glasses could aid with color vision supplementation.
