A method of manufacturing a color filter substrate includes forming a plurality of trenches having a predetermined depth by etching a surface of a transparent substrate, disposing a color filter material in the plurality of trenches to form a color filter layer, and forming a transparent electrode on the transparent substrate including the color filter layer therein.

UV absorbing appliances, such as contact lenses, are prepared by including at least one UV absorbing compound in the appliances. UV absorbing compounds can be water insoluble and/or reside in UV absorbing nanoparticles having a mean diameter less than 10 nm. The UV absorbing nanoparticles incorporate into an appliance by polymerizing a monomer mixture containing the UV absorbing nanoparticles to form an appliance comprising the UV absorbing nanoparticles. The UV absorbing compounds or the UV absorbing nanoparticles incorporate into an appliance by placing the appliance in a solution of the UV absorbing compound or a dispersion of the UV absorbing nanoparticles in a non-aqueous solvent that swells the appliance. The UV absorbing compound or the UV absorbing nanoparticles infuse into the swollen appliance and are retained within the appliance upon removal of the non-aqueous solvent.

An infrared filter includes a substrate having a front surface and a back surface. The infrared filter includes screened ink and an optically clear medium, or dye impregnated medium. The screened ink has a front surface nearest the substrate and a back surface. The screened ink has a first index of refraction. The optically clear medium abuts at least a portion of the back surface of the screened ink. The optically clear medium has a second index of refraction that differs from the first index of refraction of the screened ink by less than a predetermined amount. The dye impregnated medium has a spectral transmission over an infrared wavelength of greater than 70% and a spectral transmission over a visible light wavelength of less than 5%, while at same time maintaining MTF performance of a vision system imaging through the filter. Methods of manufacture are also described.

An optical filter comprising a variable transmittance layer having a first spectrum in a dark state, and a second spectrum in a faded state; and a color balancing layer having a third spectrum; each of the first, second and third spectra comprising a visible portion; the first and third spectra combining to provide a dark state spectrum approximating a dark state target color, and the second and third spectra combining to provide a faded state spectrum approximating a faded state target color. The optical filter may further comprise a light attenuating layer. The optical filter may further comprise part of a laminated glass.

A method of forming an ophthalmic laminate lens, includes: forming a planar laminate by adhering a first polycarbonate layer to a first side of a thermoplastic elastomer layer, and adhering a second polycarbonate layer to a second side of the thermoplastic elastomer layer, the first polycarbonate layer having a thickness greater than 250 m, the second polycarbonate layer having a thickness greater than 250 m, and the thermoplastic elastomer layer having a thickness in a range of 15 m to 150 m; thermoforming the planar laminate into a curved laminate, the curve laminate having a pre-molding curvature; arranging the curved laminate in a mold; and molding, via the mold set at a predetermined temperature and a predetermined pressure, the curved laminate with a polymer melt into a curved lens.

Described herein is a cost-effective and time-efficient method for producing photochromic contact lenses, in particular, preferably photochromic silicone hydrogel contact lenses, from a polymerizable composition comprising an unique selection and combination of main polymerizable components, a photochromic compound and a visible-light photoinitiator, based on the Lightstream Technology.
