Hi there,

Colour blindness is when someone can't see colours in the same way others can. It's often called "colour vision deficiency", and is sometimes shortened to CVD. It affects about 1 in 12 men and 1 in 200 women, so it's much more common to be colour blind if you’re a boy.

Most people who are colour blind aren’t affected by it. It's not classed as a disability in the UK and often people don't realise they’re colour blind until they take a test. There are different kinds of CVD and so it might affect you in different ways. Some people might struggle if there are certain colours close together - like coloured writing on a different colour background.

To find out if you have CVD you need to see your optician for an eye test. It's not part of the normal eye test so you'll need to tell them that you want to test for colour blindness specifically. Eye tests are free if you’re under 16 (or under 19 if you're still in full time education). The test is fast and you’ll know at the end of the appointment if you have CVD or not.

Once you have found out if you have CVD you might want to get in touch with the RNIB or visit Colour Blind Awareness for more information and support.

It could help to talk about this with an adult you trust if you are worried, or Childline counsellors are always here to listen. You can also use the message boards to get support from other young people who may be colour blind.

Thanks for your letter, I hope this has helped.
