Your glasses left me speechless.

Thank you EnChroma,

I ordered your glasses after reading so much good about them in
Reddit. I received them about two weeks ago after waiting 10 days
impatiently and I immediately took them for a walk. I put the glasses
on and started walking. At first I didn’t notice anything different
from my normal world and even though I knew that it might take a while
for them to work, I was a little disappointed. I was afraid that my
CVD was too strong to be helped. I walked with my girlfriend to a park
nearby. There were ducks swimming in a small pond and we stopped there
to watch them. Suddenly a golden green light reflected in the head of
a duck. Was I really seeing that? I asked my girlfriend to
confirm if it was real since I had never seen such a thing. I never
knew. After that I started to see vivid greens in the trees and purple
graffitis in the trash cans. The glasses were working. I was seriously

I’ll repeat the words that many others have already said: Being able
to see the world with all the reds and greens that I have been missing
is totally out of this world. Even though I have a mild protanomaly,
the difference is just mind blowing. I had no idea how much I am
missing. No more white traffic lights (now green), no more
greyish-greenish motorway signs (now crazy greens), no more “blurple”
objects (now blues and purples). There are way too many surprisingly
wonderful colorful things to mention. I have been wearing them all the
time when I’m outside and sometimes at home too. The only minus is
that the Cx-14 doesn’t work that well indoors. You can bet I am
excited about your new indoor glasses – I wish I had the money to buy
them too, or at least an opportunity to try them.

Actually, I am so satisfied and convinced of your product, that I will
definitely spread the word. I live in Finland and if I’ve understood
correctly, you don’t have a retailer here yet. If there is a way I can
help you to help people with CVD, let me know. I have some know-how in
business also. Now that the spring is coming, it would be awesome to
bring some color for the colorblind people in my country.

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.

New EnChroma Eyewear Lets the Color Blind See Colors Indoors

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

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 or from any of our retail partners listed on our website.
