Daltonism has different degrees of involvement and it is not always easy to notice if your child has this condition. In any case, it affects the male gender more. For a girl to be colourblind, her father must be colourblind, and her mother must contain a colourblind gene, but not necessarily be colourblind herself.

The reason for this is that the colourblind gene is on the X chromosome. Since women have 2 X chromosomes, as long as they have one healthy one, they will not be colourblind. As men only have one X chromosome, inheriting a colourblind X chromosome from his mother will make him colourblind.

At school, children begin to learn colours. In this learning stage we must be alert to detect if your child tends to confuse colours or not clearly distinguish them. Ninety percent of colour-blind individuals, "have trouble distinguishing red and green". This is the first step in detecting the disorder.

You can play with your child and find out if he or she is colour-blind. For example, we can play with the colours of fruits and ask: what colour is this pear? What colour is this apple? And check if your child confuses the colours. When playing, your child will be more relaxed and we can check for colour-blindness more easily.
