Introduction
Congenital red-green color weakness cannot be corrected, but colored glasses may help. Acquired color weakness can usually be corrected by treating the underlying disease, which often leads to improvement. Individuals with congenital color weakness can wear tinted lenses that transform previously indistinguishable color patterns into recognizable ones. Acquired color weakness can generally be corrected through treatment of the primary condition.

Red-green color weakness is generally caused by genetic factors or abnormalities in the color-processing nerves of the eye, resulting in poor ability to distinguish between red and green hues. It can be either congenital or acquired. Congenital cases are typically inherited, with red-green deficiency being the most common type. While congenital color weakness cannot be cured, wearing special tinted glasses can help transform previously indistinguishable color patterns into recognizable ones.
Acquired color weakness is usually caused by certain eye diseases such as fundus lesions, retinal disorders, or cataracts. It is important to actively treat the primary condition. Patients should promptly visit an ophthalmologist at a hospital. In most cases, treating the underlying disease can correct the red-green color deficiency. For example, cataract-induced color vision loss requires cataract extraction surgery. Additionally, red-light stimulation therapy may be used under medical guidance, with a reported cure rate of 35%.
It is recommended that individuals with red-green color weakness exercise extra caution when driving. Wearing color-correcting glasses can enhance contrast between red and green colors. Genetic testing is also advisable to understand one's hereditary background, which can guide family planning decisions and help prevent passing the condition to future generations.
