Abstract: A visual aid for individuals with color vision deficiencies comprises a pair of optical elements shaped to be placed in front of an individual's eyes. An interference coating is applied to one surface of each element, preferably the back surface. The interference coating comprises a stack of dielectric film of selected structure. The stack of interference films is structured to give the optical elements pre-selected spectral transmission curves. An anti-reflection coating may be applied to the front surface of each element. |
