Colours add meaning to our otherwise dull and boring life. They have the power to affect our emotions and psychology. We also use colours to interpret information such as signs and lights. Abnormal colour vision may affect virtually all facets of modern human life. Such individuals with colour vision deficiency or colour blindness find it difficult to see or identify some colours. Even though the condition is called colour blindness, technically it is not a form of blindness. Instead, it is a deficiency to see colours such as blue and yellow or red and green.

What are the symptoms of colour vision deficiency in children?

Generally, colour blindness that’s inherited can be diagnosed during childhood itself. Basically, when your child is unable to identify or recognise blue and yellow, or red and green colours, it is the first sign that your child may be colour blind. The child may have an inability to separate things by their colour. So, as a parent, you should look for signs of colour vision deficiency when your child is still learning to name the colour of objects. You can take these tests to identify colour blinddess.

Other than that, sudden or gradual loss of colour vision can indicate an underlying health problem, such as cataracts.

What causes colour blindness?

Conor blindness is mostly a genetic condition, meaning it is passed down from parents. However, in few cases, colour vision problems can also be acquired later in life due to diseases such as Alzheimer’s, Parkinson's Disease, etc., or trauma that causes brain or optic nerve / retinal damage or exposure to toxins. 

As mentioned above, red-green colour vision deficiency is the most common inherited type and is generally found in men as the vision deficiency gene is linked to the X-chromosome.
