    Approximately 12% of men and 1% of women have some degree of colour blindness. The most common type of colour blindness is red-green deficiency whereby red-green retinal cone cells have an overlapping response to light. Because their response to light is so similar this causes a wavelength deficiency and therefore the brain is unable to determine red and green efficiently. To compensate for the overlap, PILESTONE has taken existing technology and worked with leading experts to develop new and much improved materials to remove certain wavelengths that enable people with red-green colour blindness greater colour vision.
