Is there a particularly dear person around you who is color blind?
And you are often sad because of his/her color blindness?
Whenever you choose a gift for him/her, are you careful to avoid colors/patterns that he/she is not sensitive to?
Colorblind people often encounter some embarrassing moments in their lives.
For example, when his favorite “gray” t-shirt is actually green.
Or when crossing the street and can’t properly judge the traffic lights and has to follow the footsteps of others.
Now, thanks to the advancement of technology, there are special glasses for color-blind people to help them see more of the missing colors.
This may be the best gift for color blind people.
As people with normal visual systems, it is hard for us to appreciate the moment when a color-blind person puts on Enchroma or Pilestone’s color-blind corrective glasses.
However, unlike normal gifts, you need to know enough about the types of color blindness when you are helping your family or friends to choose color blindness corrective glasses as a gift.
We’ll try to help you understand the types of color blindness and how color blindness corrective glasses work with a brief description.
What is color blindness
There are three types of vertebral cells in our retina that are responsible for perceiving the three colors of light: red (L-cells), green (M-cells), and blue (S-cells). The brain synthesizes the signals from the three vertebral cells and combines them into a colorful array of colors.
Most people have all three types of cone cells working properly.
However, there are many people who have one or two vertebral cells that do not work properly due to congenital or late damage, and these are the colorblind.
On average, 1 in 12 men and 1 in 200 women have a visual defect.
Types of color blindness
Severe color blindness
Severe color blindness is a condition in which all three vertebral cells lose their ability to perceive, so that no color signals are transmitted to the brain.
People who are severe color blindness see the world as if they were watching a black and white movie.
Red-green color blindness
This is the most common type. It means that the red or green vertebrae are not working properly. As a result, the perception of red or green is affected.
For example, in cases where the red vertebrae are not working properly, the world is seen as yellowish or greenish. (Protan Color Blindness)
And if the green vertebrae are not working properly, the world is seen as reddish or yellowish. (Deutan Color Blindness)
Blue-Yellow Blindness
When the blue vertebrae are not working properly, it is called blue-yellow blindness, also known as Tritan Color Blindness.
People with blue-yellow color blindness cannot recognize true blue. The world looks greenish to the blue-yellow blind eye.
So we now know that color blindness is when the three vertebral cells have varying degrees of malfunction.
This results in a loss of the ability to “balance” colors and therefore the inability to perceive colors correctly.
How color blindness correction glasses work
First we need to be clear that color blindness corrective glasses are not a treatment for color blindness.
They work by using a special coating on the lenses to help color blind people “balance” the three colors to a certain extent.
Secondly, and very importantly, color corrective glasses are not effective for all color blindness.
And, while special coatings can help “balance” colors by suppressing or enhancing certain types of light before it enters the eye, they are not effective for everyone.
This is because each person’s vertebral cells work differently or are damaged to a different degree, resulting in differences.
Who are color blindness correction glasses for?
Current color blindness correction glasses are mainly for people with red-green color blindness (Protan, Deutan) and to a lesser extent, blue-yellow color blindness (Tritan).
Even then, a degree of perception of a specific color is required.
For example, a protan type person is most effective with protan type glasses if he/she has some perception of red, just to a lesser degree than green and blue.
The reason is that the protan coating enhances the transmission of red wavelength light and suppresses green and blue light to a certain extent, so that the three color signals reaching the brain are balanced.
If you are choosing color blindness corrective glasses as a gift, make sure that he/she only has a weak perception of a certain color, not a complete lack of perception of that color.
What color blindness corrective glasses are available？
You may have noticed that there are already several brands of color blindness corrective eyes available on the market.
However, taking into account the results of all users, only Enchroma and Pilestone color blindness correction glasses are currently the most effective. Please make your choice between these two brands.
It should be noted that according to the comparison results, people with the same type of color blindness show different results wearing the two brands of glasses. For some people Enchroma’s color correction works, while for others Pilestone works better.
This is because they use different coatings and people have different perceptual abilities, so there is no set pattern of matching.
We recommend the following for you to choose from:
In addition to the fact that the effect of wearing them varies from person to person, there is also a small difference in their prices. Enchroma is more expensive, while Pilestone is easier to accept.
In addition, both Enchroma and Pilestone have color blindness correction glasses for children.
Conclusion
For people with color blindness, color blindness correction glasses are undoubtedly the best gift. It’s just a pity that not many people seem to know about these products.
To some extent, it has to do with how much attention we pay to the lives of people with color blindness. And we also have the concept that this disease is untreatable.
And most people with color blindness don’t have much sense to change because they are used to a world of color deviation since birth.
However, many people with color blindness who have used color blindness corrective glasses have had their lives dramatically changed.
Especially when they see the colorful world for the first time, the shock and delight touches everyone’s heart.
So, if one day you wish to give an impressive gift to a person with color blindness, color blindness corrective glasses are definitely worth trying.
How many times in our lives do we have the opportunity to make a difference in someone’s life?
