Color Vision deficiency could be acquired too. Certain drugs prescribed for arthritis, depression, heart disease, high blood pressure, diabetes, multiple sclerosis, and some liver diseases can significantly affect color vision either temporarily or permanently. Continued use of aspirin can also alter color perception. Excessive use of tobacco and alcohol can have similar effects. Many industrial chemicals can permanently alter your color vision.
Certain eye diseases such as glaucoma, cataract and most eye problems affecting the retina or nerve pathways to the brain can give gradually impair your appreciation for colors. Overall blurring of near or distance vision, or gaps in the field of vision may also alter color vision perception.
Since color vision changes can be an early sign of a disease or a side effect of prescribed medication, it is important that you consult an ophthalmologist if you are experiencing any changes in your color vision. It is noteworthy that unlike inherited color deficiency, both men and women are at equal risk for the acquired color vision problems and only one eye is affected at a time.
