Can Cataracts Cause Color Blindness?

Cataracts commonly affect elderly people as clouding occurs on the lens of the eye. The clarity of vision is lost due to the condition. While it most often affects aging, there are rare occasions when it strikes younger people and even children. Too much exposure to the sun, injury to the eye, use of certain medications, and allergic reactions may play a role in the development of the disease. In addition to blocking light waves and making it difficult to see, color blindness can result as well.

As light enters the eye, it is fractured by a cataract. As the cataract worsens, the quality of vision is dramatically reduced to the point of legal blindness if nothing is done to remedy the condition. Everything loses definition due to this troubling disease. Colors will no longer be clear and it will become more difficult to identify different hues. Shadows and outlines will also become difficult to discern.

Cataracts generally begin with the appearance of halos around lights at night. As it progresses, a person will experience a dulling of the vision, and colors are affected as well. During the aging process, the cornea of the eye may begin to yellow, resulting in a problem with seeing colors properly, especially blue or violet shades. When this condition is compounded by cataracts, color vibrancy and all aspects of vision are affected. If a person has never experienced color blindness and suddenly has a problem with seeing colors, this is an indicator of a cataract or other underlying conditions that should be examined by an eye doctor. Parkinson’s Disease, Epilepsy, Kallman’s Syndrome, and Leber’s Hereditary Optic Neuropathy are other conditions that may cause problems with color perception. An eye doctor or physician will be able to help a patient to discover the root of the problem, pinpointing cataracts, or exploring other possibilities.

There are a variety of ways to address the difficulties caused by cataracts. Surgery is generally the main solution. Most patients will be able to see colors clearly again after cataracts have been effectively treated through an operation. However, if there is still a problem with identifying colors properly, there are a few other possible remedies. Colored contact lenses may help in discriminating between different colors. The use of glasses is also helpful in eliminating glare, improving the clarity and vibrancy of different colors. Individuals with cataracts should seek medical attention for relief.
