- How it Works
March 13, 2021
Most people with color blindness inherit the deficiency at birth. However, it is possible to become color blind later in life.
While genetic color blindness is most common in men, acquired color blindness affects both genders equally. If you notice any changes in your color vision, you should speak with your doctor as soon as possible because this could be a sign of a serious condition.
Ocular diseases, neurological issues, or metabolic disorders can be the cause of acquired color blindness. Additionally, there are medications used to treat systemic issues that can also cause changes to color vision. For instance, those taking the drug Plaquenil, which is used to treat rheumatoid arthritis, should have their color vision tested at their yearly eye exam.
Ocular diseases that can lead to color blindness include glaucoma, macular degeneration, and retinitis pigmentosa. Neurological issues that affect the eyes in this manner include Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, and strokes. Chronic illnesses can also cause acquired color blindness including diabetes, liver disease, and chronic alcoholism.
Sudden color blindness, especially in one eye, can be due to issues with the optic nerve. A traumatic eye injury could be the cause, or it could be due to something called optic neuritis.
Optic neuritis is an inflammation of the optic nerve which generally causes pain when the eye moves. It can also cause blurred or dimmed vision and loss of color vision. People suffering from optic neuritis may notice that the color red starts to look grayer, and there may be a blurred spot in their central vision. Optic neuritis tends to affect only one eye at a time, but it is possible for the other eye to later develop optic neuritis as well.
