Abstract:
The invention generally relates to optical filters that provide regulation and/or enhancement of chromatic and luminous aspects of the color appearance of light to human vision, generally to applications of such optical filters, to therapeutic applications of such optical filters, to industrial and safety applications of such optical filters when incorporated, for example, in radiation-protective eyewear, to methods of designing such optical filters, to methods of manufacturing such optical filters, and to designs and methods of incorporating such optical filters into apparatus including, for example, eyewear and illuminants.

Claim (Index 1):
A method of prescribing a lens to accommodate the color vision deficiency of an individual, the method comprising\n testing if the individual has deuteranomaly, testing if the individual has protanomaly, if the individual has deuteranomaly then prescribing an ophthalmic lens comprising an optical filter comprising one or more narrow-band dyes, wherein the luminous transmittance of the filter is between 40% and 80%, the red-green separation factor of the filter is greater than 1.0, and the luminous transmittance of the optical filter is defined as the weighted photopic transmittance of CIE Standard Illuminant D65 according to the CIE 1932 2-degree Standard Observer, and the transmittance of the filter at 575 nanometers is at least two times greater than the transmittance at 595 nanometers, and if the individual has protanomaly then prescribing an ophthalmic lens comprising an optical filter comprising one or more narrow-band dyes, wherein the luminous transmittance of the filter is between 40% and 80%, the red-green separation factor of the filter is greater than 1.0, and the luminous transmittance of the optical filter is defined as the weighted photopic transmittance of CIE Standard Illuminant D65 according to the CIE 1932 2-degree Standard Observer, and the transmittance of the filter at 595 nanometers is at least two times greater than the transmittance at 575 nanometers.
