Abnormal colour vision, also termed as colour blindness, is the inability to differentiate between certain hues of colour. Patients with colour blindness may not be able to recognise the difference between red and green, or blue and yellow.
Colour blindness can be an inherited condition, males are more likely to be affected in this way. Certain diseases of the eye and medications may also cause abnormal colour vision. The most common symptoms of colour blindness include:
- Difficulty in seeing certain colours
- Difficulty in differentiating shades of the same colour
Colour blindness can go unnoticed as the symptoms are usually mild. However, it can be detected when your child starts learning about colours for the first time. Your ophthalmologist can also diagnose colour blindness with routine eye examinations. Currently, there is no treatment for this condition.
