Serendipitous Fix for Colorblindness

(p. 3) The eyeglass lenses that Don McPherson invented were meant for surgeons. But through serendipity he found an entirely different use for them: as a possible treatment for colorblindness.
Mr. McPherson is a glass scientist and an avid Ultimate Frisbee player. He discovered that the lenses he had invented, which protect surgeons’ eyes from lasers and help them differentiate human tissue, caused the world at large to look candy-colored — including the Frisbee field.
At a tournament in Santa Cruz, Calif., in 2002, while standing on a grassy field dotted with orange goal-line cones, he lent a pair of glasses with the lenses to a friend who happened to be colorblind. “He said something to the effect of, ‘Dude, these are amazing,’ ” Mr. McPherson says. “He’s like, ‘I see orange cones. I’ve never seen them before.’ ”
Mr. McPherson was intrigued. He said he did not know the first thing about colorblindness, but felt compelled to figure out why the lenses were having this effect. Mr. McPherson had been inserting the lenses into glasses that he bought at stores, then selling them through Bay Glass Research, his company at the time.
Mr. McPherson went on to study colorblindness, fine-tune the lens technology and start a company called EnChroma that now sells glasses for people who are colorblind. His is among a range of companies that have brought inadvertent or accidental inventions to market. Such inventions have included products as varied as Play-Doh, which started as a wallpaper cleaner, and the pacemaker, discovered through a study of hypothermia.
. . .
EnChroma was still struggling to solve its marketing conundrum when another serendipitous event occurred: A paint company wanted to finance an ad campaign featuring the glasses. The idea was to introduce color to the colorblind. To that end, videos were made of EnChroma users wearing the glasses for the first time while looking at things like sunsets, colorful artwork and, of course, paint samples.
The ad campaign increased EnChroma’s sales and spurred a trend: New EnChroma customers began filming and sharing their experiences online. The company placed inserts in its eyeglass boxes encouraging customers to participate.
Prompted by the insert, Bob Balcom, a 60-year-old retired high school science teacher and labor relations specialist in Chatham, N.Y., uploaded his first YouTube video in March. Shot by his wife, it shows Mr. Balcom putting the glasses over his own eyeglasses and staring up at the sky quietly for several seconds. “The blue sky is deeper than I’ve ever seen,” he says. “It reminds me of Colorado. And the pine trees, they’re just so green.” Tears stream down his cheeks and into his gray beard.
