Perhaps you've heard the term 'colour blindness' and are wondering what it is. Well, colour blindness is the inability to see certain colours in what's considered a 'normal' way. People who are colour blind will confuse some colours and they will not see some colours as brightly as people with regular vision. People who are colour blind usually inherit the abnormality and have it from birth. It can also be due to brain or eye damage.
Types of colour blindness
There are 3 types of colour blindness:
Red–green colour blindness
Red-green colour blindness is the most common form of colour blindness. It is usually inherited and mostly affects males. It means you find it hard to tell reds from greens.
Blue–yellow colour blindness
Blue-yellow colour blindness is less common than red-green colour blindness and affects only about 1 in 20 people with colour blindness. It means you find it hard to tell blues from yellows. It affects both men and women.
Complete colour blindness
If you have this, you don’t experience colour at all. Complete colour blindness is extremely rare.
If you suspect you or someone you know is colour blind, it's best to seek a medical opinion as soon as possible. It's especially important for parents to be aware of colour blindness in children, as an early detection is better than a late detection. The most common way to diagnose colour blindness is through an image-based exam that displays illustrations of coloured dot patterns.
