How EnChroma Color Blind Glasses Work
EnChroma’s patented color blind lens technology has revolutionized the way people with red-green color blindness can see the world. Developed by EnChroma almost two decades ago, we’ve continually combined the latest in color perception neuroscience, optical dyes, lens material innovations, and manufacturing techniques to deliver color blind glasses that are scientifically proven to stimulate the brain’s color processing center and enhance color vision.
What is Normal Color Vision?
When light enters the eye, it activates millions of photoreceptor cone cells that can normally detect all the colors of the rainbow. The three types of cone cells, which send signals to your brain, are sensitive to different parts of the visible color spectrum and are generally referred to as blue, green and red cones.
What is Color Blindness?
Most types of color blindness occur when there is an excessive overlap of the green and red color cones in the eye, causing distinct hues to become indistinguishable. As a result, those with color blindness only see about 10% of the millions of hues and shades of colors seen by those with normal color vision.
How Do EnChroma Glasses Help Color Blindness?
EnChroma's color blind lens technology selectively filters light to increase contrast between the red and green color signals to account for the overlap and alleviate symptoms of red-green color blindness for a richer, more colorful experience of the world.

The Science Behind EnChroma Lens Technology
EnChroma develops optical lens technology that selectively filters out wavelengths of light at the point where this confusion or excessive overlap of color sensitivity occurs. The M (Green) and L (Red) photoreceptor cones are altered in such a way that there is a greater amount of difference in color discrimination along the so-called “confusion line” for that individual.

More Than A Cheap Knockoff
With the application of science, optics, mathematics, advanced neuroscience and more than 10 years of clinical research, EnChroma continues to advance the field of color vision research and bring new products to market that solve unique color deficiency issues.

Proven to Stimulate Your Brain’s Color Vision Processing
A groundbreaking new study found EnChroma color blind glasses, which are engineered with technically advanced spectral notch filters, enhance color vision for those with the most common types of color blindness. Test subjects experienced immediate improvement, which persisted long-term even after subjects stopped wearing the glasses. The researchers also found that wearing the glasses stimulated the color vision processing center of the brain. Learn more
Will EnChroma Glasses Work for Me?
Color blindness is not a singular condition. It encompasses a range of conditions, from mild to severe, that can cause each person to see color differently. EnChroma glasses are designed to improve color vision of people with forms of anomalous trichromacy, which are estimated to comprise four out of five cases of color blindness.
The most common types are Protanomaly and Deuteranomaly, which are forms of partial red-green color blindness. In the most extreme cases, the complete absence of one of the cone photopigments, called Protanopia or Deuteranopia, are considered dichromats who may see limited results due to the complete inability to see red and green color differences.
Reduced color discrimination of shades of blue and yellow is called Tritanomaly, or Tritanopia which is not a type of what is commonly referred to as red-green color blindness, but is also a form of color vision deficiency. EnChroma glasses are designed to address forms of red-green color blindness and are not intended to assist the vision of people with Tritan-type deficiency. Fortunately, most cases of color blindness respond well to EnChroma spectral lens technology, enabling the perception of bright, vibrant color. Learn more about types of color blindness.
