Colour Blind Awareness Day


Is my child colour blind?

Many parents contact us to ask this or a similar question, so if you think your son or daughter might be colour blind, read on….!

Children with colour blindness can face many challenges in their everyday lives. Watch our video here for a little insight into how they might be affected in school.

If you have a son he will have a 1 in 12 chance of being colour blind

BUT if colour blindness runs in your (the mother’s) family there is a much higher chance that your boys will be colour blind, especially if the grandfather (mother’s father) is/was colour blind. If this applies to your family then you should have your children screened for colour vision deficiency as soon as possible. Girls are much less likely to be colour blind (1 in 200 chance) and to inherit red/green colour blindness girls must have a colour blind father.

Most parents of colour blind children don’t know that they have a colour blind child and in most cases the child won’t realise either. This means a positive diagnosis can come as a shock to everyone. Parents should not feel guilty if they find out late in the day (once their boy or girl is about to sit GCSEs!) that their son or daughter is colour blind.

We’ve created factsheets for Parents specific to children of different ages because at different ages colour blind children face different challenges. Download our Parents’ advice sheets here:

Don’t feel guilty if you suddenly discover your child is colour blind because…..

colour blind children are very clever at hiding their colour blindness!

Even if children have had eye tests with opticians, colour blindness is unlikely to have been picked up because colour vision testing is not part of the standard NHS eye test. This means many opticians don’t bother to test children for colour blindness.

Often parents mistakenly think that because they were tested when they were at school, their own children will have been screened for colour blindness in primary school too. Sadly, testing has been phased out long ago by most Local Education Authorities so it is highly unlikely that your children will have been screened at school.

A recent study of 1,300 schoolchildren, undertaken by Colour Blind Awareness found that whilst approximately 75% of the pupils had been to an optometrist to have their eyesight tested, only 20% had ever had a colour vision deficiency test.

All this means that if you suspect colour blindness in your child (and if they are over 5 years old) there is a reasonably stong chance that they might have a colour vision deficiency, even if they have already had an eye test.

If you’ve ever noticed your child’s creations have colour s which might not be ‘correct’ like the one below, then there’s a reasonable chance they could have colour vision problems.

However, if you have a younger child (under 5) who seems to be slower at learning colours than you would like – DON’T PANIC! First read this article from Scientific American magazine then try to re-think the way you present colour information to see if that improves progress. If your child is still struggling with some colours – especially confusing blues with purples or reds with greens/oranges/browns then it is more likely they might be colour blind.
