EnChroma in The New York Times

Business writer Claire Martin of The New York Times interviewed our CEO Tony Dykes, and met with Don McPherson and Andy Schmeder, the scientists who developed our EnChroma lens technology. They even got a photo of Andy, our Chief of Technology, looking cool in his EnChroma Cx Gammas.

EnChroma User Videos in The New York Times

The NYT article, featured in Sunday’s business section, also included a shout out to the power of our customers’ videos.

” … 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 … “

“Guys, I’ve been staring at a Mountain Dew can for 10 minutes now. By the end of this day, I may even shed a tear… xo, Josh
This was my first reaction, in all of its unvarnished glory, after I thought I was seeing red and green for the first time.”

How Specially Designed Glasses Open Up a New World for the Colorblind

Layers of nerve cells that perform the equivalent of mathematical calculations are attached to the retinal cone cells. They compute color and brightness. To simulate this whole process in the computer, Schmeder uses a mathematical model of the basic elements of color vision. His database contains thousands of colors as diverse as leaves in various stages of growth. For every hue, he and his team calculate how much is absorbed by the retinal cone cells. So far, this is standard science, Schmeder says.

They take it several steps further, however, modifying the model to mirror different types of color vision deficiency, such as red-green colorblindness. EnChroma researchers use the model to predict how different filters will perform. Schmeder says they discovered that, given any set of conditions, finding the optimal lens for any correctible colorblindness can be represented in a mathematical format known as a linear program.

EnChroma on KPIX 5

Imagine a world without color. For millions of Americans, it’s a reality. KPIX 5’s Mark Kelly shows us a simple solution for color blindness, made right here in the Bay Area. (2/23/15)

New Glasses Transform The Way Colorblind People See The World

EnChroma, a company in Berkeley, California, has created colorblindness correcting glasses, which allow those who are colorblind to see hues they may have never experienced before. While the sunglasses, which are meant for outdoor use in daylight, were first released two years ago, the company’s new version is made from polycarbonate — a material that’s kid-friendly and usable in sports.

This well-written article explains how EnChroma’s technology works and how its helping people with color blindness:

At the back of the eye, there are three types of color-sensing cells, called cones, that respond to different parts of the spectrum of light: blue, green and red. The three overlap somewhat, but in the case of a red-green deficiency, the cones’ responses to green and red overlap too much. That causes the red and green cones to send the same, or almost the same, information to the brain, which then has difficulty discriminating between the colors. This confusion also leads the brain to mix up blended, muted colors that contain red or green, such as purple.

The proprietary lens contains a filter that blocks a portion of the spectrum where the overlap between the two cones occurs and restores the separation between them. “It’s essentially taking out that stuff that’s confusing the signal,” said Andy Schmeder, vice president of technology.

Ron Strickland tries EnChroma

When two Green Mountain Club volunteers delivered supplies to color blind hiker/author Ron Strickland on Vermont’s historic Long Trail, their box included a new pair of EnChroma Cx sunglasses. Share Ron’s and his color blind hiking buddy, Bart Smith’s, astonishment as they marvel at the beauty of autumn’s colors. Visit for information about Ron’s memoir, Pathfinder: Blazing a New Wilderness Trail in Modern America.

Revolutionary New Glasses Allow Colorblind People To See Color

While the exact reasoning behind the science is a bit complicated, they basically work by removing the wavelengths of light where overlap of red and green occur, causing the color signal to the brain to become amplified.


Color for the Colorblind

Kelly Kittell’s EnChroma Cx Receptor colorblind-correcting sunglasses arrived with the following warning: When first trying on the lens, the unusual appearance of colors may be visually distracting. “It’s a bit of an understatement. The first time I saw brick red I was so overwhelmed I stopped cold. Purple and lavender, where have you been all my life? …

Unexpectedly, the glasses make me a safer driver. Colorblind people react significantly slower to red signals, and there are a number of countries where we can’t get drivers licenses. With my Enchroma sunglasses, I can see the three distinct colors of a stoplight for the first time, and red stop signs and lit brake lights jump out with a new urgency.

EnChroma wearable tech corrects color blindness

Designers developed a mathematical model of how the brain processes color and determined how to accomplish the necessary digital spectral processing with a complex coating system. The coating consists of a stack of more than 100 layers of semi-reflective material.

How EnChroma’s smart sunglasses can help solve color blindness

EnChroma uses a mathematical formula to directly communicate with the brain’s visual system. This system is calculated to help a color-blind person observe the correct ratios the brain needs for normal color vision. The company uses over 100 reflective coatings at different opacities rather than a single tinted lens.

Glasses That Solve Colorblindness

The highlight came on Day 4 of my tests, when my kids discovered a rainbow arcing across the sky, pointing and exclaiming. I looked. With my own eyes, I could barely see it. Maybe there was a soft arc of yellow, but that was it.

Then I put on the glasses. Unbelievable! Now I saw two entire additional color bands, above and below the yellow arc. It was suddenly a complete rainbow. I don’t mind admitting, I felt a surge of emotion. It was like a peek into a world I knew existed, but had never been allowed to see.

EnChroma glasses designed to compensate for color-blindness

The key to the sunglasses’ performance is a proprietary coating on the lenses. Said to be harder and more scratch-resistant than glass, it can be tweaked in production to filter certain wavelengths that cause “color confusion.” The result is an improved signal-to-noise ratio in the perception of colors, in which red and green don’t just appear as variations of yellowy-brown – as an example.

EnChroma unveils sunglasses for the color blind

EnChroma, an optical technology company that focuses on products for people who are “color vision deficient,” has introduced its first line of sunglasses for the enhancement of color vision. More than 10 million Americans live with red/green color vision deficiency (CVD), commonly known as “red/green color blindness,” according to company officials.
