Color blindness in women is rare and is usually caused by eye injuries, acquired diseases, or medication side effects. Genetic mutations are the most common cause of color vision impairment in men, but only a tiny percentage of women inherit color blindness this way. Medical conditions, aging, injuries, and addictions can also cause color blindness in women.
Color blindness in women is rare, especially when considering color blindness inherited from genetic mutations, the most common form of color vision impairment. Few women who suffer from color vision deficiency do so because of the same genetically inherited mutations that cause color blindness in men. Instead, most color blindness in women is the result of eye injuries, acquired diseases, or medication side effects.
There are rare cases of color blindness in women linked to genetic mutations, albeit in a tiny percentage. Deficiencies related to color recognition are most often associated with inherited sex-linked genetic disorders, which are disorders associated with mutations in the X or Y sex chromosomes. Genetic impairment of color perception results from a defective or mutated X chromosome. To have the hereditary variety of color blindness, an individual must inherit defective X chromosomes from a parent. As for color blindness in females, this would require both parents to pass on similarly defective X chromosomes, a statistical rarity.
Genetic abnormalities and sex-related disorders are the typical cause of color blindness in men, but not necessarily in women, according to statistics compiled from numerous studies. Color blind women are much more likely to have acquired conditions that cause color blindness. Based on statistical data and documented cases, color blindness in women typically occurs sometime after birth. Injuries to the retina, certain types of diseases, and adverse drug reactions are more likely to cause color blindness in women than inherited genetic disorders.
For example, some medications used to treat rheumatoid arthritis have been linked to acquired color blindness in both men and women. Hydroxychloroquine is one such arthritis drug with a known link to acquired color blindness. Similarly, some heart medications such as digoxin can cause color vision problems if there are too many drugs in your system or if you overdose. Where drug toxicity is a suspected cause, color blindness may be transient depending on the severity and appropriateness of the initial diagnosis and treatment.
Similarly, medical conditions such as glaucoma and other eye diseases can also cause color blindness in women just as easily in men. Macular degeneration, complications of diabetes, multiple sclerosis, and cataracts, along with many other medical conditions, can also cause color blindness in women. Aging has also been linked to problems with the visual cortex in both men and women, which can lead to color blindness in some elderly patients, regardless of gender.
Injuries and certain addictions can also cause color blindness in women. Accidents that damage the actual eye or areas of the brain associated with vision can affect whether or how colors are perceived. Tobacco poisoning and alcoholism have been linked to vision damage resulting in color blindness and other vision problems. Malnutrition and certain eating disorders that result in malnutrition can, in some patients, lead to color vision problems. Whether a patient’s color blindness is permanent depends on the cause, appropriate treatment when warranted, and the patient’s overall health.
