It let them see true color for the first time.
A YouTube video shows two colorblind brothers seeing true color for the first time thanks to EnChroma glasses.
EnChroma glasses are specialty eyewear that "alleviates red-green color blindness, enhancing colors without the compromise of color accuracy." The eyewear is not a cure for color blindness, but it's effective about 80% of the time, EnChroma writes on its website.
"It's so bright," one of the young men says as he cries and holds his brother.
It's a beautiful moment.
And it's a humbling reminder that technology can play a more meaningful part in our lives than giving you a faster way to stream Netflix.
