How EnChroma Colour Blind Glasses Work
EnChroma’s patented colour blind lens technology has revolutionized the way people with red-green colour blindness can see the world. Developed by EnChroma almost two decades ago, we’ve continually combined the latest in colour perception neuroscience, optical dyes, lens material innovations, and manufacturing techniques to deliver colour blind glasses that are scientifically proven to stimulate the brain’s colour processing center and enhance colour vision for most people with red-green colour blindness.
What is Normal Colour Vision?
When light enters the eye, it activates millions of photoreceptor cone cells that can normally detect all the colours of the rainbow. The three types of cone cells, which send signals to your brain, are sensitive to different parts of the visible colour spectrum and are generally referred to as blue, green and red cones.
What is Colour Blindness?
Most types of colour blindness occur when there is an excessive overlap of the green and red colour cones in the eye, causing distinct hues to become indistinguishable. As a result, those with colour blindness only see a fraction of the millions of hues and shades of colours seen by those with normal colour vision.
How Do EnChroma Glasses Help Colour Blindness?
EnChroma's colour blind lens technology selectively filters light to increase contrast between the red and green colour signals to account for the overlap and alleviate symptoms of red-green colour blindness for a richer, more colourful experience of the world. Approximately 80% of those with red-green colour blindness will see some improvement in their ability to distinguish colours.

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 colour sensitivity occurs. EnChroma lenses alter the signal to the M (Green) and L (Red) photoreceptor cones in such a way that there is a greater colour contrast 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 colour vision research and bring new products to market that solve unique colour deficiency issues.

Proven to Stimulate Your Brain’s Color Vision Processing
A groundbreaking new study found EnChroma colour blind glasses, which are engineered with technically advanced spectral notch filters, can enhance colour vision for those with the most common types of colour 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 colour vision processing center of the brain. Learn more
Will EnChroma Glasses Work for Me?
Colour blindness is not a singular condition. It encompasses a range of conditions, from mild to severe, that can cause each person to see colour differently. EnChroma glasses are designed to improve colour vision of people with forms of anomalous trichromacy, which are estimated to comprise four out of five cases of colour blindness.
The most common types are Protanomaly and Deuteranomaly, which are forms of partial red-green colour blindness. In the most extreme cases, the complete absence of one of the cone photopigments, called Protanopia or Deuteranopia, are considered dichromats who would see no results from our glasses due to the complete inability to see red and green colour differences.
Reduced colour 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 colour blindness, but is also a form of colour vision deficiency. EnChroma glasses are designed to address most forms of red-green colour blindness and are not intended to assist the vision of people with Tritan-type deficiency or Dichromacy where only two of their three colour sensing cones are functioning. Fortunately, most cases of colour blindness respond well to EnChroma spectral lens technology, enabling the perception of bright, vibrant colour. Learn more about types of colour blindness.
