Colour blindness is a vision problem in which differentiating between blue and yellow or red and green becomes difficult.
It is caused when one or more of the light-sensitive cells found in the retina of the eye respond to certain colours differently than how people without this condition see those colours.
It is an inherited condition and impacts males more than females.
If there is a change in your vision you may be subjected to colour blindness. Sometimes people affected by this problem would be able to see no shades of certain colours while others they would be able to see may all look exactly the same.
Furthermore, colours may become less bright than before making them seem dull.
This condition can be mainly observed when toddlers are being taught the different colours. It would seem that they can face this problem because they would be unable to associate certain colours with appropriate objects.
However, children can learn that whatever colour they see is called the name they have been told even though they might see a colour different than what the others see.
Moreover, children who suffer from this deficiency in school are not treated any differently, it isn’t believed to be an impairment or disability which causes them further problems.
High school students aren’t properly advised as to which career options may suit them and which choices may be tough for them to pursue. In the likelihood that they suffer from color blindness, they surely have access to limited career options.
Around 1 out of 12 males and 1 out of 200 females are thought to be colour blind.
The effects of colour vision deficiency can be mild, severe and intense it varies from person to person.
If colour blindness has been inherited the condition might be the same of the person during their whole life.
Moreover, there are many diseases which can lead to colour blindness as well if the nerves have been damaged or due to an accident the retina gets affected.
A simple age factor such as increasing age may cause colour deficiency, also when people grow old they find it difficult to see things, sometimes they loose their vision and/or become gradually colour blind.
Furthermore, there are three main types of colour blindness that exist today:
Red or Green
The first type of colour blindness is when the difference between red and green is hard to tell.
Yellow or Blue
In the second type, the person has difficulty between yellow and blue as they appear similar.
Black or White
The third type is known as achromatopsia, in this the person cannot see any colour at all and to them everything is black or white. However, this type of condition is rare.
Famous personalities such as Bill Clinton [American politician] has this condition and finds it difficult to distinguish between red and green whereas Mark Zuckerberg [creator of Facebook] is red green color blind.
In some cases, glasses or lenses can be recommended by doctors to improve the vision and ability to see certain colours.
To treat this deficiency, gene therapy may be required and maybe repairing of the damaged chromosomes as well.
No exact scientific method has been identified which completely cures colour blindness even though researchers are working to find out some treatments for the condition.
People fail to believe that colour blindness is an impairment and disability just like all the others which is one of the reasons why effective research for it’s cure has not been pursued.
