Eyesight is such a wonderful gift, and it’s a shame that how people without any eyesight or color blindness miss out on our wondrous world and all its mystique and beauty.
Our world, and indeed the worlds beyond, are incredibly beautiful and awe inspiring place which loses its allure and fascination simply because we have grown up looking these things and view them as “normal”. The effect induced by monotony can be recognized after watching the people who couldn’t view the world the same way most of us have. This is the case with the colorblind people who were “blessed” by science to view the world with all its magic and liveliness thanks to a pair of glasses.
The first video shows Noll Stafford, a colorblind man from Florida who was gifted the Enchroma glasses on his 66th birthday that allowed him to see the colors like us all for the first time in his life!
The reaction is simply priceless:
I’m not crying; someone must have been cutting onions again!
If that didn’t choke you up, here’s a whole collection of people trying the Enchroma for the first time and being humbled to their knees at the splendor of the world and its colors.
So what’s the science behind Enchroma glasses?
First, you need to understand how color blindness works. Despite the popular perception, most of the colorblind people don’t view the world in complete black-and-white. This does happen under the condition called achromatopsia but is extremely rare.
Human eyes have three types of color-sensitive cells: red, blue and green-sensing cones. Three of them combine to provide the vibrancy and color to our world.
But for some people, the cones don’t work as a team and start to detect overlapping light spectrums, thus cutting down the number of hues their eyes can distinguish. These overlaps can be specific to each person and usually come in either red-green or blue-yellow color blindness, with the latter being more common.
These deficiencies can be seen in the illustration below, although the severity of deficiency varies a great deal between individuals:
As evident above, people with red-green deficiency look at certain colors completely differently, usually with a muddy brownish hue. Purple is indistinguishable from blue, and pink may not exist at all.
Keeping this in mind, the Enchroma glasses were designed to specifically help with red-green deficiency. The glasses were originally made to be used as protective eye-wear for doctors working with laser surgery, but it was soon realized to be capable of much grander purposes.
Using computer modeling, red-green color blindness was simulated, and then the patent-pending Enchroma lenses were designed which filters precise wavelengths of the visible spectrum causing the color signals to be amplified.
Thus a colorblind person is aided in filtering out the overlapping signals from red and green cones, and perceiving these wavelengths separately helps in viewing the complexity of color vision.
People using the glasses comment on how everything looks brighter since the Enchroma filters make most of the colors along the red-green spectrum extremely vivid. The company claims that this is not a cure for color blindness cure but rather an ‘assistive optical device.’
The technology doesn’t work for people with blue-yellow color blindness, yet. You can buy these amazing contraptions at US$349 for adults and US$269 for kids.
