How common is it and who does it affect? Colour blindness can develop later in life and affect men and women equally. What changes would someone notice?
What underlying conditions can cause acquired colour-blindness? Dry AMD - the light-detecting cells of the retina gradually die leading to loss of the central part of the patient's vision the part of the vision we use for reading, driving or when recognising faces.
Dry AMD can come on gradually and can get worse slowly over the years. These treatments are still experimental and are not yet ready to be used in clinic patients. In wet AMD, fragile blood vessels grow into the retina damaging the light-sensing photoreceptor cells. This can happen over days or weeks and patients can suddenly develop vision related symptoms such as altered colour vision, distortion or blurred vision. When should I see an eye doctor?

An accident resulting in severe trauma to the eye or a stroke that affects parts of the brain can lead to the development of a color vision deficiency. Antibiotics, high-blood pressure medications, and medications used to treat nervous disorders can potentially create a color vision deficiency over time. Industrial or environmental chemicals can create color blindness.
Carbon monoxide or chemicals that contain lead are some common contributors. Color blindness is commonly known as a genetically inherited deficiency. However, chronic illness, severe accidents, medications, and contact with chemicals are all additional ways you can become color blind. Skip to main content. Search form Search Website. Genetics The most common way color blindness develops is through genetics.
This is known as "red-green" colour vision deficiency. It's a common problem that affects around 1 in 12 men and 1 in women. In rare cases, some people have trouble with blues, greens and yellows instead.
This is known as "blue-yellow" colour vision deficiency. Ask for a colour vision test at an opticians if you think you or your child may have a colour vision deficiency, particularly if it started suddenly or is getting worse. Colour vision tests do not usually form part of the routine NHS eye test , but you can specifically ask for them.
There are a number of online tests using similar techniques that may help detect a possible problem, but it's best to have a proper test at an opticians if you have any concerns about your colour vision. Most people get used to it over time, it will not normally get any worse, and it's rarely a sign of anything serious.
Overall, many people with a colour vision deficiency have few, if any, difficulties. They can do most normal activities, including driving.
There's currently no cure for inherited colour vision deficiency, although most people are able to adapt to it over time. Visit Colour Blind Awareness for more information and advice about living with colour vision deficiency.
If your colour vision deficiency is caused by an underlying condition or a medication, your symptoms may improve by treating the cause or using a different medicine.
