Have you ever asked yourself, “Why does that green look more like brown?” or “Why do others see colours I don’t?” You may have colour vision deficiency, commonly known as colour blindness.
At The JHB Eye Lady, we help patients every week who are just discovering how colour perception affects their lives—especially in school, driving, or choosing clothing.
How to Test for Colour Blindness
One quick and effective way to screen for colour vision issues is the Ishihara Colour Blind Test. Try it online here:

This test uses patterns made of coloured dots to detect red-green or blue-yellow deficiencies. But for a comprehensive, accurate diagnosis, an in-practice test is always recommended.
What Causes Colour Blindness?
Colour blindness is usually inherited and affects 1 in 12 men and 1 in 200 women. It can also develop from eye disease, injury, or medication side effects.
Can It Be Treated?
While there’s no cure, specialised lenses and glasses can enhance contrast and colour distinction for some types of colour blindness. We offer advice and solutions for daily life and safety.
