Colour Vision Deficiency affects around three million people in the UK — roughly one in twelve men, and one in two hundred women. Most live with it quietly, without ever being properly assessed.

Often called colour blindness, the condition is usually inherited and means certain shades — most commonly reds and greens — appear muted, confusing, or indistinguishable from one another. It does not stop people living. It simply changes the way they see the world, often without them realising how much.

The impact can be quieter than people expect. Children adapt before they know what they are adapting to. Adults learn to ask others which shirt matches, which wire to choose, whether the meat is cooked through. Capable people are quietly ruled out of careers in aviation, electrics, design, medicine and the emergency services — not because of talent, but because of colour.

For generations, there was no real solution. Today, there is.

ColourOn lenses are MHRA-registered Class I medical devices, engineered specifically to aid colour discrimination. Worn like any prescription eyewear, they selectively filter the wavelengths of light the eye struggles to separate — giving the brain the contrast it needs to see colour with new clarity.

The difference is often immediate. Reds emerge from browns. Greens lift away from greys. Clothes, food, screens, signage, sport, faces, fabrics — the world simply arrives in fuller resolution.

At ColourOn UK, we work with a growing network of accredited Centres of Excellence — qualified opticians who properly understand colour vision, and the people living with it.

If you, your child, or someone you love has spent years working around colour, now is the moment to do something about it.

See every colour. Every thread.
