deuteranomaly and protanomaly
terms used for people who suffer from red-green colourblindess and have trouble distinguishing between reds, greens, browns and oranges. They also commonly confuse different types of blue and purple hues.
I had friends at school that used glasses that created a tint to their vision helping them to read whilst having dyslexia. Apparently the use of a different colour of paper/text could increase some people’s ability to read more easily. It’s quite incredible that colour can have such a big effect on, not just your appreciation and understanding of the world around, you but can also benefit the way you learn and even allow you to read easier than a monochrome page. The thought of a life without colour makes me incredibly sad. When I was younger I used to think that the world used to be black and white. I hated when it was a grey day, I would look at old family photo albums filled with black and white photos of grandparents, and even parents, and I used to get sad thinking that they had to live in such a grey world.
The two types of light-sensitive cell within the retina that process colour are called the rods and cones, the rods work in low-light condition, such as at night time, whereas cones work in the daytime in high level light conditions. There are three types of cone cells, each having a different sensitivity to wavelengths of light; one perceives blue light, an other red light, and the last green light.Your brain then interprets the signals from the cones cells so that you can see the colour of the object. The red, green and blue cones all work together allowing you to see the whole spectrum of colours. The exact physical reasons behind colour blindness are still being researched but it is believe to be caused by faulty rods and cones.
I found these really funky glasses that have lenses which alleviate colour blindness, by enhancing colours but without compromising colour accuracy. EnChroma lenses solve the problem by the use of an optimal filter that targets specific photopigments, using some protected/patented method they are able to filter and cut out and sharp wavelengths of light allowing the enhancement of specific colours. They do this by separating the overlapping red and green cones, improving the difference in these colours for people who struggle to differentiate. Literally incredible. The technology for this was created and designed through research into the genetics behind colour blindness along and looking into various anomalies related to photopigments. Seeing, and seeing in colour, is something I totally take for granted on a daily basis. Colour blindness is something most sufferers are born with, imagine being gifted with something like being able to see colour.
