WHAT IS ENCHROMA?

Up to 300 million people worldwide are affected by red-green color vision deficiency, also called color blindness.
EnChroma invented glasses that boost color vision by spectrally separating light into primary color components before it reaches the eye. By enhancing the saturation of colors, the lenses can improve speed and accuracy of color recognition and enrich the experience of color in the world
 
Introducing EnChroma®

EnChroma lenses look like ordinary tinted lenses, but when you look through them something amazing happens: your experience of color vision is fundamentally transformed.

Colors appear more vibrant, saturated, full, and yet without compromising the accuracy or color balance of the scene. Colorful objects, such as flowers, colorful paint and fabrics, food, and traffic signs suddenly “pop” with a heightened purity and intensity.

Experiences like a rainbow or a sunset, seen for the first time with EnChroma, are magically transformed beyond any rational description.

Of course, there is nothing actually magic in this - it’s all based on science and technology — that is, color vision science and optical technology.

                Symptoms and Causes of Color Blindness
  
 
Enchroma color blind lenses and frame A person with red-green color blindness (more accurately called color vision deficiency) experiences the world differently because their red and green photopigments have more overlap than normal. By overlap, we mean spectral overlap, which is related to how the photopigments absorb light. Let’s take a moment to understand how that happens:

The photopigments are the light-absorbing molecules found in the 6-7 million retinal cone cells of the eye. When these molecules absorb photons of certain wavelengths, they undergo a chemical transformation which causes the cone cell receptor to fire a nerve impulse. The photopigment molecule is then “re-set” and ready to absorb more photons.

Normally there are three distinct classes of cone cells: one class absorbs mainly red light (called the L-cones), another absorbs mainly green light (the M-cones), and another absorbs blue light (S-cones). But, in a person with red-green color blindness, one of those is anomalous. For example, the L-cone absorbs too much of the green light (a condition called a PROTAN deficiency), or the M-cone absorbs too much of the red light (DEUTAN “doo-tan” deficiency).

Returning to the subject of this spectral overlap: the situation is analogous to how two adjacent radio stations might bleed together (which is called “cross-talk”). It makes a mess of conflicting information, and the more the L-cone and M-cone signals overlap, the greater the confusion or extent of color vision deficiency. Can we correct for this problem somehow? Well, there is hope: the eye is fundamentally healthy, the neural wiring for processing color is intact and correct, and for the vast majority of cases (greater than 80% of red-green color blindness), the amount of overlap is less than 100%. (If there is 100% overlap, then there is no way to provide differential filtering.) Essentially, the system functions normally, but it’s getting bad data. The problem is in how the light is received, which is where the EnChroma lens comes into play.
