There are many things that we may take for granted, and one of those is our sense of sight. We try to take care of it regularly, going to have our vision checked and wearing corrective lenses if necessary. There are some people, however, who have problems with their vision and there is nothing that can be done about it. They are colourblind, and they see the world around them differently than most people do.
Colourblindness is not all that uncommon. It affects approximately 8% of men and 0.5% of women. In most cases, a person who is colourblind will be able to see colour but they have an inaccurate perception of what it looks like. Very few people who are colourblind see in black and white. The following will help you to have a greater understanding of how people with colourblindness see the things you see.
This is a person with normal vision
Deuteranomalia is a common form of colourblindness and in most cases, a person doesn’t even realise they have a problem. It affects the brightness of colours, especially red and green.
Protanopia affects approximately 1% of men. All shades of red and green appear to be faded. Blue and yellow shades remain unchanged.
Tritanopia is a rare form of colourblindness. People who have it see the world in greenish pink tones
Only 0.00003% of the worlds population has total colourblindness.
