Colour Vision Deficiency (CVD) or colour blindness affects 3 million people in the UK, making up about 4.5% of the entire population.
Most people with CVD have protanopia or deuteranopia, affecting red and green light perception, respectively. Tritanopia, which affects the perception of yellow and blue light, is less common. About 1 in 30,000 people have monochromacy, which means they can’t see colours at all and see everything in shades of grey ranging from black to white.
Having CVD can affect a worker’s ability to perform certain tasks. If an employee’s colour vision is important for the purpose of safety, then the HSE says that colour vision testing is critical in deciding on their fitness for such tasks.
This online Colour Blind Test can help users detect if they have CVD. It shows images depicting circles of apparently random colours and sizes and asks users to identify numerals in patterns in them. Earning a perfect score on this test can help serve as evidence of perfect colour vision, whereas failing the test can indicate a degree of colour blindness.
Due to the difference in colour perception on-screen compared to in-person, accurate results cannot be fully guaranteed. If this test leads you to believe that you might have a degree of colour blindness, you should see a licensed optician for a formal diagnosis.

While this online test can help you check if you have colour blindness, it is not a substitute for a professional medical examination.
