WHAT IS COLOR BLINDNESS?

Color blindness (or color vision deficiency), is a condition where a person’s eyes are unable to see colors under normal light. People with color blindness have a hard time telling colors apart from each other.

HOW EYES SEE COLOR

The retina contains approximately 6 million retinal cone cells. Each cell is ‘color specific,’ responding mainly to light of specific frequencies. The three different types of cone cells correspond to the three primary colors: red, green and blue.

WHO IS AFFECTED?

Color blindness affects millions of people worldwide. It affects 1 in 12 men and 1 in 200 women. The condition ranges from a variety of classes, red-green color blindness being the most common.

Most people who suffer from color blindness are not blind to color, but have a reduced ability to see them. Color blindness is also called Color Vision Deficiency (CVD).

CVD can be acquired, but most are inherited genetically. The genes that influence the colors inside the eyes, called ‘photopigments,’ are carried on the X chromosome. If these genes are abnormal or damaged, color blindness occurs.

SYMPTOMS & CAUSES

A person with red-green color blindness sees the world differently. Their red and green photopigments have more overlap than normal, making them unable to see certain colors. EnChroma found a way to alleviate this by creating a specialized lens that filters out specific colors.

SOLVING THE PROBLEM

Creating the lens started out as computer simulations, constructing sophisticated models that simulated colors and the extent of color vision deficiency. To create this model, EnChroma utilized the latest research on the genetics of color blindness and various anomalies related to photopigments, and linked these into a model where it gives the effect on how people with red or green color blindness perceive colors.

The second step was to solve the problem by designing an optimal filter, targeting specific photopigments. EnChroma created a (patent pending) method called ‘multinotch’ filtering, cutting out sharp wavelengths of light to enhance specific colors. EnChroma lenses separate the overlapping red and green cones, helping improve vision for people who have difficulty seeing reds and greens.

The EnChroma Story

Great things start from small beginnings, and some begin as fortuitous ‘accidents.’ Don McPherson, who has a Ph.D in Glass Science (Alfred University), noticed certain color transformations when he wore his lab glasses, coated with a special lens formula he had invented for laser surgery eye protection.

The discovery led to a research study. Clinical trials of the early prototypes revealed that the lenses had benefits serving as an optical aid to the color blind. The research was conducted under NIH SBIR grants, with test sites allocated at UC Berkeley and UC Davis.

Despite all the advancements, there was still more work that needed to be done to turn the lenses into a consumer-ready product. Don teamed up with Andrew Schmeder, who specialized in several fields including mathematics, computer model simulation and perceptual psychology. Together, they co-founded EnChroma, Inc. in 2010.

EnChroma set out on developing the prototypes into a scalable product. The first version launched in 2012, followed by innovations in creating lightweight plastic lenses, prescription lenses, and broad acceptance by professional eyecare communities in 2014.

The story does not end there, however, since it’s just getting started. EnChroma is continuously committed to researching and developing more effective, safer and useful products that will help the color blind see the world differently; by giving them the gift of color.
