World Vision Day is celebrated at the initiative of WHO on the second Thursday of October to draw attention to problems and people who have vision problems.
According to some data, today more than 285 million people have problems, and, according to doctors, many could have been avoided if appropriate assistance had been rendered to the person on time.
Of course, there are diseases that can be treated, and there are only those that can be tried to compensate for: color blindness, or color blindness - one of them. And, nevertheless, today there are attempts to control this - EnChroma glasses
The lack of color vision was first revealed in 1798 by John Dalton, on whose behalf they named this ailment. Despite the description of the feelings associated with the disease, attempts to somehow convey the perception of the surrounding world, it is difficult for an ordinary person to understand color blindness.
Trying to systematize and summarize the learning experience, doctors note the following.Color blindness
is often the inability to distinguish between certain shades of colors, and the most common type of blindness is the nondiscrimination of red-green shades. Rare forms of complete color blindness are characterized by the ability to see only black and white and gray shades.
Loss of sensitivity can be hereditary and acquired. In the latter case, as a rule, the color ceases to distinguish one eye, in the case of the genetic one, both. Light-sensitive cones in the retina, which are responsible for broadcasting color information, stop doing this and people in the place of indistinguishable colors can see a neutral gray color.
Non-hereditary forms of color blindness can be caused by trauma or diseases, among which there are:
- macular degeneration
- Alzheimer's disease
- Parkinson's disease
- multiple sclerosis
- chronic alcoholism
- sickle cell anemia
Also of the reasons:
Cure is impossible
- The use of drugs against cardiovascular diseases, drugs for high blood pressure, infections and psychological disorders
- Accidental contact with chemical fertilizers and certain other substances.
To date, there are no tablets against color blindness, and this lack of perception can only be compensated for, both with and without special glasses.
For the convenience of recognition, you can resort to the help of relatives and friends to mark certain things and objects. Also, some tend to remember the order of things, rather than their color, for example, the order of colors at a traffic light, etc.Glasses
One way to compensate for the disease can be special lenses. Considering that the most common type is nondiscrimination of red and green hues, they took it up.
One of the pioneers in this area is X-Chrom lenses
. They were created for people with an acquired form of color blindness, who had a loss of sensitivity in only one eye.
The lenses, as written on the official website, were not treated at all, but they facilitated the perception of some colors, enhancing the shades on the non-dominant eye. However, the majority of tests showed that improving results with the help of X-Chrom was obtained only during clinical tests, while in the natural environment lenses did not help orient much.
This is also an achievement, of course, but rather of an informational nature.EnChroma
One of the most high-profile and, perhaps, unique projects of recent times, about which all major publications wrote.
The video about how an adult man sees color for the first time, virally scattered across the network and scored over 1 million views in a month, and this is touching!
Examples of how EnChroma works in pictures are also quite quickly scattered across the network, and spread with extraordinary trepidation.Without glasses | With glassesBut is everything simple and universal?
Yes and no. The authors of the project claim that EnChroma works in 80% of cases, enhancing color perception. A special strip on the glass captures the color, pushing the cones apart and distributing photons between them.What cones and photons?
As explained, all people in the eye have three cones that are responsible for “recoding” colors for the brain: red, green, and blue.
Blue is considered to be independent, but red and green can “mix”. 10 photons “land” on red color, 100 photons - on green, and yellow color will dominate in the picture, whereas with equal distribution it would be “correct”.
Thus, the secret of the lenses is in the filter, which is able to separate the cones overlapping each other, helping people suffering from a weak distinction between red and green colors
In addition to enthusiasm, there is criticism. Some people are suitable, some are not, and this is a natural process, but you can also take a lot of useful information from critical reviews.
For example, about how the "addictive" to the glasses. The point is that instant results are not available to everyone and, on average, it takes an average of 15 minutes to an hour and a half to “adjust the vision” and adapt to the lenses. Drastic changes in most cases also do not have to wait, the perception returns gradually.
They do not cure! Some users disappointedly noted that they hoped that the glasses would have a stimulating effect, but this is not so: while the glasses are on the nose, the color discrimination is improved as soon as the glasses are removed, everything is as before.How to buy
EnChroma glasses with lenses are sold, including in Russia. In our catalog there
are several models, but there is an opportunity to choose an individual frame for the lenses. Pleasure is not the cheapest - from 30,000 rubles.
How the purchase process takes place, you can learn more from telephone operators: since the thing is extremely individual, there are some peculiarities.
