The glasses block specific wavelengths to create a clearer separation of different color signals so that they can be better calculated by the brain. To eliminate the overlapping of the wavelengths of light, there is an optical material called a 'multi-notch' filter, is capable of removing the exact wavelengths of light in the location where it overlaps, getting a simplified differentiation of colors. The most common form of color blindness is known as deuteranomaly, it is genetic and an X-linked trait that affects up to one in every 12 men (8%) and one in 200 women (0.5%). EnChroma lenses focus on the most common color vision deficiency which is caused by the red and green retinal cone cells that, when responding to light, coincide. The optical filter used in EnChroma lenses can improve or modify aspects of color vision deficiency (CVD).
