How colorblind people see the world
Everyone's heard about colorblindness, a
significant number of global celebrities such as Bill Clinton, Keanu Reeves, Mark Zuckerberg, and even Prince William are known to be color blind.
But do you know what color blindness is? Color blindness, also known as color vision deficiency
Is not a disease, but to decrease the ability to see color or differences in color.
Approximately every one in twelve men and one in 200 women are affected by it.
So there's a high probability that someone you know, a neighbor, or a co student is colorblind.
There are four different types of colorblindness, each of them provides deficiency in different color shades
For a person with normal vision it is hard to imagine what it is like to be colorblind
And how people like this see the world.
Which color do they see? Do they see any at all? What does it mean not to be able to see red and so on?
That is why we at bright side prepared a visual comparison of all color blindness types and put them together for your better understanding.
Let's have a look together
People with normal vision usually see the world around them in these colors
However people with Deuteranopia, the first type of color blindness see the same picture like this
Deuteranopia is the most common form of colorblindness.
of men suffer from it and in many cases don't even realize it
It's clear from the photo that the colors have lost some of their brightness especially with regard to green and red
And people with protanopia see these pencils like this.
Protanopia is a less widespread form of colorblindness
Only around 1% of men experience it. All shades of green and red
appear somewhat faded and blue and yellow shades remain virtually unchanged
The third type of color blindness is Tritanopia, and they see colors like this. Though a very rare type of colorblindness,
Tritanopia affects both men and women to an equally small degree
Those who experience it see the world in greenish pink tones
The last type is total colorblindness. It is hard to imagine,
but it exists. However, only a small percentage of people are affected by it.
Only 0.00003% of the whole world's population.
And now let's have a look at the straight comparison.
How about a piece of fruit, normal vision?
Tritanopia. And together, impressive, isn't it?
Now traffic lights, it is widely known that people with color vision deficiency can have difficulties while driving.
By looking at these pictures you will understand why.
Here is normal vision
This is protanopia
And that's tritanopia
and together again. Quite an eye-opener.
A popular soda label, normal vision.
Tritanopia. Together. My world will never be the same.
What about a rainbow? Rainbow with normal vision.
Together. So Richard of York gave battle in vain. Indeed.
Street traffic. Look at the street car. Normal Vision.
And now the final example.
Frida Kahlo was a Mexican Painter in the first half of the 20th century.
Was she ever thinking about how her paintings could be seen by colorblind people? Well we don't know about Frida.
But you are going to see it right now.
Are you still with us? Then here are some historical facts for you.
Colorblindness as a vision deficiency was discovered by English chemist, John Dalton after he realized that he was color blind himself.
In 1798 he published the first scientific paper related to the subject which was called
Extraordinary Facts Relating to the Vision of Colors. Due to his immeasurable amount of input into the research of
colorblindness the general condition has been named after him and known as Daltonism though as
Wikipedia states in english this term is now used only for Deuteranopia.
