Cutting-Edge Lens Technology and Eyewear for Color Blindness
EnChroma eyewear combines the latest in color perception neuroscience and lens innovation to help people with color vision deficiency experience color they never thought possible.
Types of Color Blindness
Color blindness (also spelled colour blindness) or color vision deficiency (CVD) includes a wide range of causes and conditions and is actually quite complex. Usually when people talk about color blindness, they are referring to the most common forms of red-green color blindness, which are genetic conditions caused by a recessive gene on the X-chromosome, but there are other types as well.
Red-green color blindness can be broken down into two main types: Protan-type (“pro-tan”), which is a disorder of the first “prot-” type of retinal cones also called the L-cones, and Deutan-type (“do-tan”) which is a disorder of the second type of retinal cone also called the M-cones.
How EnChroma Glasses Work
It is estimated that an average person with normal vision typically sees up to 1 million shades of color. In the eyes of people with color blindness, there is a greater overlap of the red and green cones' sensitivity, reducing the number of shades seen by up to 90% and causing frequent color confusion. EnChroma's lens filtering technology removes light where the problematic overlap occurs, restoring color discrimination, vibrancy, and clarity.
