Colour vision deficiency (CVD) is a quite common condition: roughly 32 million people are affected in Europe alone. There’s a colour deficient person in every second (extended) family and a colour deficient child sitting in every third classroom. 

There are multiple types of CVD, as well as different levels of severity. Most colour vision deficient people have red-green type CVD and experience difficulty distinguishing yellow, orange, red, green and brown - roughly all shades of colours except for blue and violet. At times, this can make it difficult to perform certain tasks that involve colours.

Colour Vision Deficiency occurs when the wavelength sensitivities of particular photo receptor cells in the eye overlap more than they should - this increased overlap causes many colours to be indistinguishable from one another.COLORON optics are designed to eliminate wavelengths of light which contribute to the signal overlap, and to amplify the red-green signals entering the eye.

By filtering out the wavelengths with the highest overlap, the COLORON lenses are designed to improve the distinction between colours.

This results in a broader spectrum of colours and hues and enables both protan (red) and deutan (green) colour vision deficiency types to differentiate with better success. COLORON colour vision enhancing glasses are not a cure, but a versatile tool that can be activated on demand to enable functional colour vision for when its needed.
