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.

– Color Blind People Can See Colors Indoors to Overcome Classroom, Occupational, Safety, and Other Limitations –
Berkeley, CA – March 18, 2015 – EnChroma – the company bringing color to the color blind – today announced an innovative new line of EnChroma Cx-65 eyewear for indoor use. The EnChroma glasses enable red-green color blind students, children, workers – anyone suffering from color vision deficiency (CVD) – to see and appreciate a more colorful world. One in 12 men, and approximately one in 200 females, have some form of CVD, of which approximately 80% can be helped by EnChroma eyewear.
“A lot of EnChroma sunglass wearers wanted an indoor version so they could bring the experience of seeing certain colors for the first time to their lives at work and at home,” said Tony Dykes, CEO of EnChroma. “Everything from learning at school, or presenting a colorful slide show at work, to debating with friends about the infamous ‘gold-and-white or black-and-blue dress,’ is much easier with EnChroma Cx indoor glasses. We’re excited to help CVD kids overcome learning obstacles at school, or to enable someone to enter a field requiring color-identification capabilities.”
The EnChroma Cx indoor glasses enable kids (and others) to more quickly and accurately identify and interpret important color-coded information at school and outside of class. Color blindness is often considered a mild disability, but studies estimate that two-thirds of the 300 million people with CVD feel it’s a handicap.
“As an optometrist, EnChroma gives me an exciting technology to prescribe for the needs of my CVD patients in a complete range of lighting conditions,” Dr. Gary Louie, Doctor of Optometry (OD) of Family Vision Care Optometrics in Union City, California.
“I was mesmerized by the vivid imagery I saw when I put on EnChroma glasses and the colorful visuals started trickling in,” says Trevor Oppliger, a deputy district attorney in Fresno, California. “I fought back a wave of emotion as I began absorbing how much impact the glasses were going to have on my life.”
A wonderful short documentary called Color for the Color Blind shares evocative personal stories from four color blind individuals and their reactions to experiencing certain colors for the first time wearing EnChroma glasses. The film was produced by Valspar Corporation (VAL), a global leader in the paint and coatings industry. Watch the film at ValsparColorForAll.com.
EnChroma’s Cx indoor glasses are available in prescription and non-prescription eyewear, and in polycarbonate for pediatric, sports and industrial safety usage. Try EnChroma Indoor Cx glasses for 30 days risk-free by ordering at enchroma.com or from any of our retail partners listed on our website.
EnChroma is dedicated to positively impacting the lives of the estimated 300 million people worldwide with color vision deficiency. EnChroma has developed a robust line of innovative eyewear products with cutting-edge optical technology for men, women and children. The company is led by a team of seasoned researchers, engineers, and technology experts, backed by an advisory board of world-renowned vision scientists. Based in Berkeley, California, EnChroma emerged from a National Institutes of Health SBIR grant designed to study the feasibility of correcting color vision deficiency.

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.
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.

EnChroma Launches Color Blindness Correcting Eyewear for Pediatrics, Sports, and Prescription Markets
– Glasses Help Color Blind People See Colors to Overcome Limitations that Affect Careers, Activities, and Tasks –
Berkeley, CA – December 9, 2014 – EnChroma – the company bringing color to the color blind – today announced a new line of EnChroma Cx eyewear based on prescription-capable polycarbonate (plastic) lenses that enable color blind athletes, children and others to safely engage in any activity while seeing more color. EnChroma Cx glasses provide people with color vision deficiency (CVD) spectral color enhancement in a plastic lens that makes the eyewear a viable option for a huge new base of users.
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.

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.

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.
From Optometry Times
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.
