Glasses To Make Color Blind See – In recent years, videos of color-impaired people showing their first experiences of seeing the world in color have gone viral. In these videos, color blind people are often given corrective glasses and end up changing lives. Corrective glasses allow people with color defects to finally see the world in full bloom. There is currently no cure for color blindness, so these glasses are the next best solution. But how do color blindness corrective glasses work?
Color blindness impairs vision by reducing the depth and vividness of certain colors. Cone photoreceptors, often called cones, are located in the retina of the eye and are responsible for color perception based on their sensitivity to light. The three types of color-sensing cones are red, blue, and green, and are responsible for sending wavelengths to the brain for interpretation. People often experience color blindness as difficulty seeing red and green. This is a result of the similarity between the wavelengths that detect green light and red light, making it difficult for the brain to distinguish between the two colors.

Prescription glasses use a light filter inside the lens to differentiate and enhance color vibrancy, depth and detail. This filtering prevents overlapping wavelengths of red and green, which usually confuse the brain and cause distortions. Then the brain will be able to correctly distinguish the colors that fall on top of each other. These glasses cannot change the condition of the complete absence of photoreceptors, but they are an excellent solution for the color blindness associated with the deficiency.
Enchroma Glasses For Colour Blind People: They Really Work
In short, color-blocking corrective glasses improve light filtering by blocking overlapping wavelengths, allowing people with this deficiency to see vivid and full colors. With this technology, people suffering from color blindness can now enjoy sight. Studies have shown that while they change the perception of colors already perceived, they do not restore normal color vision.
Glass scientist Donald Macpherson accidentally invented Chroma glasses. He initially sought to develop lses to protect and assist surgeons during laser procedures.
The image above shows a normal scene through normal ls and the bottom shows the same scene through Chroma ls.
The information focuses on the most common color vision deficiency caused by the red and green cone cells of the retina that respond to light. To eliminate overlapping wavelengths of light, there is an optical material called a notch filter, which can remove specific wavelengths of light where they overlap, resulting in a simplified color gradation. The glasses block certain wavelengths to create a clearer separation of different color signals so they can be better calculated by the brain. Signal separation allows most colorblind people to distinguish between colors, but glasses have little effect on the 20% of colorblind people who are severely colorblind.

A 2017 study of 23 men between the ages of 20 and 25 showed that Cx-14 chroma Cx-14 ls discriminates between the blue and purple regions of the visible spectrum. This prompted participants with normal color vision to experience a tritan defect while wearing ls.
In a later study involving t people with genetic defects (nine men and one woman aged 19 to 52), Chroma Cx-14 filters had no significant effect on the vision of colorblind people and “improved error rates in only two people. “.
In 2018, Chroma lse research showed that they help colorblind people see the same colors differently because the color filter changed the way colors appear in their eyes.
The researchers found that the effect of using Chroma glasses is similar to glasses, where the use of colored filters changes the user’s perception and increases the contrast between colors, for example, for shooting or hunting. The study found that Chroma glasses showed no improvement in the Ishihara and Farnsworth-Munsell 100 color tests.

A 2020 UC Davis Health Eye Cter study in collaboration with the French Institute of Stem Cells and Brain INSERM found that Chroma improved color vision for those with the most common types of red-gray vision. The study showed that the color change effect remained even after the glasses were removed. Autumn is approaching and with it comes a beautiful change of scenery. The leaves are starting to turn beautiful yellow, gold and red colors. But millions of people cannot see these colors. It is estimated that there are 300 million color blind people in the world.
WAFF 48 News checked out a company called EnChroma that says it can give people the gift of color vision with certain types of glasses. The company offered to ship the glasses to us for free. We posted a message on Facebook asking for volunteers to try the glasses.
Ryan Fannell was one of our volunteers. He is a Decatur firefighter and paramedic with Cullman EMS. We caught up with him and his family at the Huntsville Botanical Garden to try out these glasses.
“Everything has more red. Should these bricks be red? This is definitely different. It’s very bright and vibrant. It’s like my life in (HD) high definition,” Fannell said.

Funnel’s reaction was amusing and the EnChroma sunglasses worked for him. His wife said she can now help him choose clothes for his daughter.
Our next volunteer was Darrin Jurado, Graphic Designer and Technical Director at WAFF 48. He also tried on the glasses.
“Wow, everything is so colorful. This is red. Everything is very vivid. When I wear them everything is bright and I like it,” said Jurado.
According to Jurado, the glasses gave him headaches over time, and he occasionally took them off to rest his eyes. I talked to her a few days later and she said she doesn’t wear them every day.

Jurado and Fannell found positive as strong protons. Protans are people with protanoma, a form of red-green color blindness.
An EnChroma representative says the glasses help separate the red and green cone signals, making them more vivid and clear.
For Raytheon engineer Bob Pratico, his wife surprised him with such glasses a few years ago.
“I was excited! I went out on the deck at Green Mountain where there were green trees and blue sky. I couldn’t believe how green everything was. I just stood there in awe and wondered if the world really looked like this,” added Pratiko.

Meanwhile, Jurado and Fannell tested open sunglasses and EnChroma closed sunglasses. I mean, the reaction was much stronger with the sunglasses and they noticed a bigger difference.
Their price ranges from 200 to 400 dollars. So if you’re going to spend the cash, I’d go for the sunglasses.

Being color blind, McKinley “Mac” Erves never knew what he was missing. But on Monday afternoon, her friends showed her a whole new world when they gave her a special color-blind gift for her 22nd birthday.
Types Of Color Blindness
Her honest and sweet reaction to the glasses that changed her life instantly went viral.
“I have no words,” Herves said. “It made me feel so good that they actually went out of their way and remembered and did it when I never expressed how much I wanted glasses for myself.”
As of Tuesday night, his Twitter video had more than 150,000 likes and dozens of positive responses.
“I’ve just mentioned that I want tinted glasses and my friends are trying to get me a pair for my birthday to show how much they love me – and I couldn’t ask for anything better. I wouldn’t mind People calling me bro!!!” Erves wrote in his post.
How Color Blind Corrective Glasses Work
I almost never mentioned that I wanted tinted glasses and the fact that my friends went out of their way to get me a pair for my birthday, how much they loved my ass, and I called better people. I didn’t ask them to leave Iraq. my brothers!!! pic.twitter.com/0BKOeftxYC — Mac (@maciavelli_) January 4, 2021
In the video, Herves is seen exclaiming as he walks down his hallway, inspecting everyday objects in full color.
“Brother what?!” – he shouted excitedly looking at the green bush in front of his house. “Brother, there is no way you can see this…”
Erves — a student at LaGrange College in Georgia, about 65 miles southwest of Atlanta — has a type of color blindness that makes it difficult to distinguish specific shades of green or red, he said. But when he put on the ONKE glasses, he said, the common green bush in his front yard was “killed.” He said he hadn’t taken them off during the day since he got them.

“With the glasses you see things as they should be,” he said. “I always saw what I saw, but when these glasses corrected my vision, it was something I will never forget.”
Herves discovered he was color blind when he took a color blindness test in high school. It had never bothered him before, he
