The Truth Behind Being Colour Blind

 

How many of us taken for granted our ability everyday to identify and see a  plethora of colours and hues? Taking in a vibrant rainbow, a milky colourful sunset or sunrise, or even clothes shopping…being able to identify a variety of colour is essential to our everyday world.

 

For some individuals – they live in a very different reality. Being colour blind is different for every person who identifies having it. While those who are colour blind take in the world differently, there are ways to adapt and make life easier. While our curiousity has us finding some interesting facts about being colour blind, we can’t help but appreciate our full colour vision a little bit more than we usually do.

 

15 interesting facts you never knew about being colour blind…

  1.  More commonly found in men – stats show 1 in 12 males vs the 1 in 200 females are affected by the vision deficiency.

  2. There are three types of colour blindness, the most common is red-green, the other is blue-yellow and the last, complete colour blindness where no colour is detected at all.

  3. Red-green and blue-yellow colour blindness is actually more accurately known as “colour vision deficiency’.

  4. Of those who are diagnosed with being colour blind, 99% of them have red-green colour blindness.

  5. Much like baldness – colour blindness is linked to the mother’s genetics. This hereditary deficiency is passed on the 23rd chromosome which is the X sex chromosome.

  6. If a female is colour blind, it is almost a guarantee any or all of her male born children will be colour blind. On the flip side, if it is the father who is colour blind he will not pass his vision deficiency to his sons.

  7. There are various degrees of colour blind ranging from mild to severe – and it can be as individual as the person with varying abilities to distinguish hues and colours.

  8. Those who have a strong colour blind deficiency might only be able to detect 20 hues of colour apart while a full colour vision person can detect 100+ hues differently.
