Colour Blindness

What is colour blindness? Actually, that can be quite misleading If you have colour blindness, it means you see colours differently than most people. It occurs because some of the colour-sensitive cells in the eyes, called cones, are either missing or do not work properly.

Red-green colour blindness is the most common type of colour deficiency. Also known as deuteranopia, this is most likely a congenital condition, meaning that you’re born with it. Most common in men it affects 6% of the UK male population. Because women have two X chromosomes and can overcome the handicap of one, men have only one and are therefore more often affected.

When you have a look at the colour spectrum of a deuteranopic person you can see that a variety of colours look different than in a normal colour spectrum. Whereas red and green are the main problem colours, there are also for example some grey, purple and a greenish blue-green

which can’t be distinguished very well.

This is also known as trichromatism. In all, it’s estimated that the human eye can see 10 million different variations of these colours.

Deuteranopia is a type of red-green colour blindness characterized by the inability to distinguish red and green pigments. Protanopia is another type of red-green colour deficiency. Both are primarily caused by recessive genes in the X chromosome.


Red-green colour blindness is the most common form of colour blindness

It’s about 8% of the UK population suffers from colour blindness

Most of the time, colour blindness makes it hard to tell the difference between certain colours. Usually, colour blindness runs in families. There’s no cure, but special glasses

People with colour vision deficiency CVD find it difficult to identify and distinguish between certain colours. Most people with colour vision deficiency have difficulty distinguishing between shades of red, yellow and green.

What can be done?

The filters (EnChroma glasses) are designed to increase the separation between colour channels to help people with colour blindness see colours more vibrantly, clearly and distinctly.

FL-41 A rusty rose colour that is usually tinted to darkness of 50%. It has been found useful in reducing eyestrain, tension headaches and migraine. It is thought that indoor lighting contains flickering blue light. This filter blocks about 80% of that component.

So colour-blindness glasses don’t “fix” colour blindness, but they can make it easier for people — colour-blind or not — to tell colours apart. It should be noted that because there are different types of colour blindness, for some people, these glasses won’t do anything at all.
