The present invention is directed to an optical filter that attenuates specific areas of the visible spectrum corresponding to the peaks of absorption of both the S-cone and rod cells within the human retina. The optical filter can be configured to also selectively block at least a portion of light centered at either one or both of the peak absorptive wavelengths of the human M and L-cone cells. The optical filter can be included within or on any optical system that is able to transmit all or part of the visible spectrum. As such, the present invention also provides an optical system that acts as a phototoxicity filter for the eye and can be used in conjunction with any material where visible light has at least partial transmittance.

La présente invention concerne un filtre optique qui atténue des zones spécifiques du spectre visible correspondant aux pics d'absorption à la fois du cône S et de cellules à bâtonnet dans la rétine humaine. Ledit filtre optique peut être configuré pour bloquer également sélectivement au moins une partie de lumière centrée sur une longueur, ou les deux longueurs, d'ondes d'absorption de pic des cellules humaines de cône M et L. Ce filtre optique peut être inclus dans ou sur n'importe quel système optique capable de transmettre tout ou une partie du spectre visible. En tant que telle, la présente invention concerne également un système optique qui agit comme filtre de phototoxicité pour l'il et peut être utilisé en conjonction avec tout matériau pour lequel la lumière visible possède une transmittance au moins partielle.
