Chances are, you know someone who’s colour blind. Have you ever wondered what the world looks like through their eyes?
Here is your chance to have a peek. It’s really quite cool, and you can even choose the type of colour blindness you’d like to view.
There are many different causes for colour blindness, and it can be genetic. Most of the genes involved in colour vision are found on the X chromosome, meaning that men are more likely to be colour blind than women.
Interestingly, one study suggests that about 1% of women have a fourth colour cone, as opposed to the normal 3, and this makes them tetrachromats. They have a fourth cone in between red and green, giving them an increased ability to differentiate colours.
This is all rather speculative at the moment, as it seems that human tetrachromats have yet to be confirmed.
