Just imagine spending all your life without seeing a color like green or red, and then all of the sudden see it for the first time ever. Although most color-blind people in the world wouldn’t ever get that chance, Noll Stafford from Florida has been presented with that fantastic opportunity at his 66th birthday party.
His kids got together to buy him a pair of special glasses that correct color-blindness, and luckily, the unique moment was captured in video.
You can clearly see how emotional Stafford got as soon as he put them on, and could see the color for the first time, and since he is a landscaper, seeing the colorful flowers and plants for the first time must have been amazing.
Actually, Stafford isn’t the only one lucky enough to see in all colors, the company that produces the glasses, called Enchroma, usually encourages their users to capture their first reactions to color in film and share them.
The company’s strategy is actually brilliant, and a new video is popping up at YouTube every few weeks, and most of them are very emotional like this one we’ve seen.
Here is a compilation of the company’s favorite reactions back in 2015, and we know you just going to love them.
But enough about emotions, and let’s talk about how the Enchroma glasses actually work, and what color-blindness actually is.
The term itself, color-blindness is actually not the best of terms to use, since it gives the idea that people who suffer from it see the world in black and white, which is not true (although there’s an extremely rare condition named achromatopsia, where people actually don’t see any colors at all).
The human eye in general has three types of color-sensitive cells, namely the blue, red and green sensing cone, and they all act together so we can have a rich and colorful vision experience.
Now, what happens with people who suffer from the condition, is that there is a misalignment of the cones, that diminishes the number of hues the eye can distinguish.
Then, depending on the misalignment, people can have red-green, or blue-yellow color-blindness (although the first is much more common).
In the image above, from Johannes Ahlmann, found at Flickr, you can see a comparison.
Now let’s go back to the Enchroma glasses, that focus mostly on the red-green deficiency. These glasses were originally developed to protect doctors during the process of laser surgery, but soon it was found that the technology had applications outside the hospitals too.
The glasses lenses, were specifically designed using computer models to simulate the red-green color blindness, to correct the condition, by removing very precise wavelengths of visible spectrum.
As a result, the brain of those suffering from the condition can better separate the misaligned signs from red and green cones, making your color vision all of the sudden come to life.
Bellow, you have a comparison image by Enchroma itself that helps you better understand the big difference for the person who suffers from color-blindness.
The glasses price start around 340 dollars for adults, and 269 to kids, and although it is not a cure for the condition, it’s definitively a huge improvement to their vision and to have the full color experience.
