Color is an essential part of the lives of sisters Angie and Michelle Dreher, who run Two Tone Press, a letterpress print shop in midtown Kansas City, Missouri.
But after watching a short video on Facebook, lack of color recognition grabbed their attention.
"It's like, maybe, a 2-minute video. But I was like crying," says Angie Dreher, who watched the video as people tried on EnChroma glasses. They're designed to boost and improve color vision for those who are color blind.
