Enchroma color eyewear solutions are effective for approximately 80% of patients with color blind

When light hits the human eye, it reaches the S,M and L photoreceptor cells, forming three channels of signals, which are transmitted to the cerebral cortex for mixed processing (similar to the RGB color system), so that humans can perceive the world’s colorful colors.

In normal human eyes, L-type cones and M-type cones are coordinated in number and function. Abnormal color vision occurs when there is a loss of number or function in the L and M cones (the spectral response curves of the M and L cones are close or even overlap), which is a common red-green vision abnormality. When the number or function of M-type cones is abnormal, the color vision is green.

When the L-like cones are abnormal in number or lack of function, the color vision is called red vision. The reddish-green color disorder is a congenital disorder controlled by an invisible gene. There are no drugs or other medical methods to treat or correct this color disorder.

Based on the generating mechanism of the human body red green sleep disorder, put forward and designed a kind of suitable for red green felt unusually individuals have significantly increased the body color resolution strategy, namely before the incoming light into the eye.

To a certain spectrum modulation: M and L cone cells into the peak response of the wavelength shift effectively filter part of the spectrum, thereby eliminating the abnormal spectral response of the overlap part of color distinguish haunt, increase the spectral response is not the color of the overlapping part distinguish weights, and then achieve the function of human body color resolution improved significantly.

How to realize this complex multi-narrowband spectral modulation? This function is realized by designing several complex optical film systems.

Color enhancement scheme, through spectral modulation, light separation, color enhancement to help people with abnormal color vision to see a different colorful world! Color enhancement can greatly improve chroma and color recognition, most of the color saturation can be increased by more than 20%, especially red, green and blue primary colors.

Color blind glasses are optical assistance device,and do not cure color blindness/weakness. Depending on the type and degree of aberration of color blindness/weakness in individuals, enchroma color blind glasses have a significant effect on approximately 80% of patients with red-green color blindness.
