An optical filter may reduce the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 590 nm, and a visual spectral response of the human eye. The optical filter may disrupt the isomerization of melanopsin in the human eye reducing the availability of the active isoform, whereas the attenuation of light weighted across the action potential spectrum of the active isoform attenuates the phototransduction cascade leading to photophobic responses. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response. Methods of use and methods of manufacturing optical filters are also described.

An optical filter for eye glasses, in particular suitable for spectacle lenses or ski goggles, has a spectral power transmission curve of optical radiations. The spectral power transmission curve exhibits a local maximum spectral transmission (T.sub.max) of radiations in a first wavelength range (Δλ.sub.max). The first wavelength range (Δλ.sub.max) is between 380 nm and 420 nm. The spectral power transmission curve exhibits spectral transmissions (T) of radiation in a second wavelength range (Δλ.sub.th) which are lower than an upper threshold spectral transmission (T.sub.th,u). The second wavelength range (Δλ.sub.th) is between 420 nm and 500 nm and the upper threshold spectral transmission (T.sub.th,u) is smaller than the maximum spectral transmission (T.sub.max). The maximum spectral transmission (T.sub.max) is larger than 21%.

An ophthalmic spectacle lens having transmittance properties that block UV and violet light and partially block certain cyan wavelengths to enhance contrast between blue versus green and partially block certain yellow wavelengths to enhance contrast between green versus red, and keep in accordance with the tristimulus values. Adding wavelength-selective organic dyes provides the entire functional attributes of the current invention or improves the contrast-enhancing attributes provided by a glass wafer having functional rare-earth oxides, either of which improve multi-band spectrum that is balanced in blocking UV light, and adding contrast between the primary colors to optimize color-enhancing functions. When using organic dyes for all functional attributes it is possible to integrate these dyes into plastic ophthalmic materials. Some lenses are polarized. Unlike other color-enhancing sunglass lenses, this invention may help protect the eyes from over-exposure to some high-energy visible blue light, which may lead to age-related macular degeneration (AMD).
