Quick answer
What is Colour blindness?
Colour blindness (colour vision deficiency) is difficulty telling certain colours apart, most commonly reds and greens, and less often blues and yellows. It happens when the colour-detecting cells in the retina do not work in the usual way.
- How it is treated: Inherited colour blindness cannot be cured and usually needs no treatment, as most people adapt well and it does not affect their health or the clarity of their vision.
- Self-care: Practical strategies help: using labels and patterns as well as colours, colour-identifying apps and tools, good lighting, and letting schools or employers know where colour-coding matters.
- When to seek help: Inherited colour blindness usually needs no medical treatment; an optician can confirm it with a colour vision test.
What it is
Colour blindness (colour vision deficiency) is difficulty telling certain colours apart, most commonly reds and greens, and less often blues and yellows. It happens when the colour-detecting cells in the retina do not work in the usual way. The most common form is inherited and present from birth, affecting far more males than females because of the way it is passed on, and it does not change over time. Less commonly, colour vision can be affected later by eye conditions, some medicines, or other health problems. Despite the name, it is not a form of blindness and does not affect the sharpness of vision — most people with it see clearly and simply perceive some colours differently. It can occasionally cause practical difficulties (for example with certain colour-coded tasks or careers) and is picked up with specific colour vision tests.
How it is treated
Inherited colour blindness cannot be cured and usually needs no treatment, as most people adapt well and it does not affect their health or the clarity of their vision. The focus is on practical support and awareness: knowing about the condition helps with tasks that rely on colour, and there are strategies and tools (such as labelling, using patterns as well as colours, and apps) that help. Certain tinted lenses or filters help some people distinguish colours better in some situations, though they do not restore normal colour vision. For children, letting schools know can help with colour-coded learning materials. If colour vision changes later in life (rather than being lifelong), this is assessed, as it may indicate an underlying eye or health condition that needs attention. Awareness is the main "treatment" for the common inherited form.
