Hundreds of million people worldwide suffer from protanomalous and deuteranomalous CVD (otherwise known as red/green color blindness). This problem is more common in men, with an estimated 1 in 12 having some sort of color related vision deficiency. My Dad is color blind and so is my boss. Women can also have this problem, but it’s not as common. EnChroma sunglasses feature special lenses that have an advanced optical coating technology that enables them to perform highly specific filtering of light reaching the eye. These lenses selectively block the wavelengths of light that contribute most to color confusion and as a result help improve their color vision. The EnChroma Cx series glasses will be available in October. Pricing is not yet available.
