Many of us go throughout our days experiencing life in every shade of colour imaginable, watching colours outside change as the seasons pass or even something as simple as getting the full experience from movies and videos. It is hard to imagine having limited colour vision.
Even without realising it, many people throughout the world are colour blind, with estimates placing the number somewhere around 300 million people who are affected across the globe.
In simple terms colour blindness is when someone is unable to see colours in the way that most people with normal vision can. In most cases, people affected by colour blindness only have a select range of colours that are impossible for them to see.
Colour blindness is usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women.
So how does colour blindness work? You have two different types of cells known as “rods” and “cones.” While rods are responsible for detecting light and dark, your cones are the ones that detect different colours in the light hitting your eyes.
The light that normally touches your eyes is seen as white or containing every colour within it. When this light enters your eye, different cones are used to detect three different colours—red, blue, and green—at which point can then be translated into every colour imaginable when combined in the right way.
Sometimes your cones may overlap, meaning that your red and green cones are not able to do their job properly, leaving you with a muddled view of reds and greens, but leaving your blue vision undisturbed. Since there are different combinations of colours that can be created, there are also various types of colour blindness, including red-green, yellow-orange, green-brown, pink-grey, blue-yellow, or blue-purple.
There is currently no cure to correct colour blindness, however Pilestone Africa is here, giving everyone the chance to experience life in full colour while wearing Pilestone glasses.
The lenses we’ve developed selectively filter out certain light wavelengths at the point where your different coloured cones overlap, removing any sort of confusion your brain has while trying to differentiate colours. This leaves you with lenses that give you the full ability to see the true colours of the world.
Although you will not have the same colour vision without our glasses, while using them, any symptoms of colour blindness will disappear, leaving you with a full view of every colour the world has to offer. Have you ever asked yourself the question: ‘’am I colour blind?’’. Well, if you suspect yourself or a loved one might have a type of colour blindness, our expertly crafted colour blindness test is here to help answer whether or not that is true.
