It is wrong to think that color blind can only see white and black. The reason is, there are many types of color blindness, from those who cannot see the colors blue, red, yellow, to green. In fact, there are very few cases of people who can only see white and black. Most of them are unable to see red and green. Now, there are special glasses for people with color blindness. What are you like?
Glasses for people who are color blind
Color blind glasses are for those of you who experience partial color blindness, especially red and green. Glasses are designed with a special colored lens which can help to better distinguish red and green colors.
Keep in mind that these glasses cannot cure your color blindness because this problem is a congenital disease. However, color blind glasses can help you to see a wide spectrum of colors more accurately. There are several types of glasses that can be used, namely:
1. EnChroma
It is the most famous color blind eyewear product from California today. According to EnChroma, the lack of color vision ability occurs due to an abnormal overlap of light waves in people with color blindness.
These color waves are not properly captured by the cone cells, the cells in the nerves of the eye that function to see color. This is where EnChroma lenses come into play, they help to reduce the overlap of those abnormal light waves. So people with color blindness can see more of the spectrum of light that the eye could not properly perceive before.
Apart from the various videos of EnChroma's successes that were viral in the mass media, there is still a lot of controversy regarding the capabilities of these eyeglass lenses. One study involving 10 adults with red-green color vision disorders found improvements in color vision only occurred in two people. So further research is needed before we can mention EnChroma lenses as a means of improving color vision.
2.Color Correction System (CCS)
Not much different from EnChroma's color blind glasses, CCS also uses special filters to help improve color vision. CCS is specially designed to meet individual needs and filters can also be used on contact lenses.
Does that mean that with the help of these filters a person with color blindness can see colors like a normal person? Of course not, red and green color vision gets better just when wearing glasses and still can't distinguish the color spectrum as well as normal people. The filter will also not work if worn by those with total color blindness.
So, to find out which glasses are suitable for you, you should consult a doctor. The reason is, these glasses must also be adjusted to the condition of your eye lenses, whether you need an additional minus, plus, or cylinder lens.
