Color blindness is something that can happen at a young age or later on develops as the person ages. Someone who has this deficiency will not be able to distinguish one color from another or may not be able to see an image clearly on a background.
This could be genetic or is caused by an injury in the optic nerve or retina. The person may not be able to distinguish between red and green in the beginning or blue from yellow and studies have shown that this can get worse over time.
However, there are more patients who get this deficiency because of heredity and it happens more often to men than women. Some people may be partial meaning, the individual will not be able to discern some colors while this could be complete for others but such cases are very rare.
The part of the eye that allows people to distinguish one color from the other is the photoreceptor. Those who don’t have problems identifying the pigments are known as trichromats while those that do are called anomalous trichromats.
Color blindness also affects how someone sees a graphic image. A normal person may see a number in the background while those who have this problem don’t. The sad part is that there is still no treatment or cure for this deficiency.
Since many only suffer from mild symptoms of this problem, scientists have come up with a way to make this work. This is done by using a spectrum graphic analyzer that can aid the person in seeing things better.
The first thing this machine will do is transform more than 16 million colors into a smaller figure to about 256. This is also used in graphic pictures on television and any other object that the person sees.
Then, the individual will have to learn the colors and in time get to see an object more or less the way someone with normal vision can.
This device is the first step of many that will be taken to help those who are suffering from color blindness. Hopefully a surgical procedure can be developed just like how doctors are able to help patients with cataracts see again.
Spectrum graphic analyzers are not only used to help patients who are color blind. This is also used to record video and audio. The individual can download this into the computer and then review the recorded footage.
