Colour blindness causes you to see colours differently from most people. In most cases, colour blindness makes it difficult to distinguish between some colours. Colour blindness usually runs in families.
This condition has no cure, but special contact lenses and glasses can help. Most people with colour blindness can adjust and have no issues with everyday tasks.
The most common colour blindness makes telling the difference between green and red difficult. Another type of colour blindness makes it difficult to differentiate blue from yellow. People with complete colour blindness do not see any colour, but this type of colour blindness is rare.
The inability to see colours like others is the main symptom of colour blindness. If you are colour blind, you may experience difficulty seeing:
Colour blindness symptoms are usually mild, making them barely noticeable. Since we often get used to how we see colours, many people who are colour-blind remain unaware of it.
People with serious cases of colour blindness may experience other symptoms, like sensitivity to light and nystagmus (quick side-to-side eye movements).
Women have a lower risk for colour blindness than men. Your risk of colour blindness is higher if you:
Consult your eye doctor if you think you have colour blindness.
Diagnosing colour blindness may be difficult as children may try to hide their colour blindness. However, being colour-blind may make reading off a chalkboard and other activities more difficult, so getting your child tested is important.
If you have a family history of colour blindness or your child seems to have trouble learning colours, testing the child is necessary. Your child can get tested at school or at the child's eye doctor.
Genetics is the most common cause of colour blindness, meaning you can get it from your parents. Colour blindness can also occur due to damage to the eye or brain and may worsen as you grow older, usually due to cataracts.
An eye doctor can perform a simple test to check if you are colour-blind. During this test, the eye doctor will show you a circle of several coloured dots. The circle has a shape inside made of dots, like a squiggly line, a letter or a number. It is easy to see the dots if you aren't colour-blind, but people with colour-blindness may find it difficult to see them.
Colour blindness passed down in families has no cure, but most people can adjust. Children with colour blindness will need help carrying out some classroom activities, and adults cannot do some jobs like graphic design or being a pilot. However, colour blindness doesn't always cause serious problems.
If you have colour blindness due to other health problems, your doctor will recommend treatment. If you are taking any medicine that causes colour blindness, your doctor may adjust your dosage or suggest taking another medicine.
If your colour blindness causes problems with daily tasks, some devices and technology can help. They include:
Special glasses and contact can help people with colour blindness differentiate between colours.
Visual aids, apps and other technology can help people living with colour blindness. For example, you can take a photo with an app on your mobile device and tap on the part of a photo to find out the area's colour.
You can discuss your options with your eye doctor. These tips may help:

I had an absolutely wonderful experience doing Lasik at this clinic. Their entire staff was extremely professional and courteous throughout the entire process.
My surgeon was wonderful, made me feel entirely at ease before and during surgery. Highly recommended.
Laser eye surgery, now glasses free after 23 years! :)
I have always thought about laser, I have worn glasses for 23 years. I was very anxious, worried about the what ifs. I had an appointment with Dr Mani, he explained everything to me and I decided to go ahead with the surgery. It was so fast, Dr Mani did remind me to be patient and I think this is very important. I am now glasses free and hoping this will continue! After care was good, a week after surgery I was concerned and Dr Mani invited me down to check my eyes to be sure all was ok. Thank you
LASIK with Dr. Mani
I had LASIK surgery with Dr. Mani. It was painless, smooth, and everything went well. The staff and Dr. Mani are all friendly and will answer all questions asked. Will recommend 100%! Thank you!
I had a great experience performing my laser eye surgery at Optimal Vision Clinic. All the staffs are very helpful, co-operative and supportive throughout the treatment process. On the first call, they explained the entire procedure in details and gave necessary instructions at every stage. My eye surgeon made me feel comfortable and relaxed before and during the procedure. Aftercare was done properly with a thorough check-up of my eyes. I would like to recommend this clinic to everyone!
Very happy and impressed with the highly professional care and service I’ve received at the Optimal Vision clinic. Dr Mani is so professional, and he explained everything about Laser surgery and answered all my questions. The surgery was quick and almost completely painless. My eyes have healed perfectly and quickly. I would highly recommend this clinic.
My husband had been experiencing discomfort in his left eye since July and was seen by various doctors/consultants even at the Queen Mary’s hospital but no abnormalities were found.
This week Dr. Mani discovered the fault which happened to be Retina detachment with three tears.
Dr. Mani’s preciseness and his perfectionist attitude to attention to details, detected the source of the main issue and saved my husband’s eye. We feel utterly grateful and can not recommend him enough for his excellence.
