Abstract: A high energy visible (HEV) light absorbing material and application method for an ophthalmic substrate includes deposition of an HEV light absorbing material onto the ophthalmic substrate. The HEV light absorbing material is applied through physical vapor deposition as a thin layer on ophthalmic substrates for flexibility and color adaptation. The HEV light absorbing material includes at least one of: aluminum zinc oxide, indium zinc oxide and gallium zinc oxide with a material commonly used in the design of antireflective absorbing materials. The HEV light absorbing coating is antireflective and transmits up to 98% of light for the rest of spectrum. The HEV light absorbing material allows the ophthalmic substrate to selectively absorb blue light that falls in the wavelength range of about 400 nm to about 460 nm.

Abstract: The presently presented inventive lens will provide an eyeglasses/sunglasses wearer with improved perceptions of color saturation and optical contrast without requiring any apparent coloration (except gray) in the transmitted tint (although other colors may be used), promoting a sense of heightened accuracy and differentiation in viewed colors while providing full protection from UV. Further, the lenses of the invention provide increased visual acuity, and maximize the visibility of objects partially obscured by fog or atmospheric haze. Lens embodiments having certain spectral-transmission properties as defined herein achieve one or more of these objects, while filtering out (i.e., providing local/relative minima) of certain human-visible light wavelengths in a manner enhancing crisp color perception.

Abstract: Computer eyewear for reducing the effects of Computer Vision Syndrome (CVS). In one embodiment, the eyewear comprises a frame and two lenses. In some embodiments, the frame and lenses have a wrap-around design to reduce air flow in the vicinity of the eyes. The lenses can have optical power in the range of approximately +0.5 to +2.5 diopters for reducing accommodation demands on a user's eyes when using a computer. The lenses can also include prismatic power for reducing convergence demand on a user's eyes when sitting at a computer. The lenses can also include a partially transmissive mirror coating, tinting, and anti-reflective coatings. In one embodiment, a partially transmissive mirror coating or tinting spectrally filters light to remove spectral peaks in fluorescent or incandescent lighting.

Abstract: A photochromic polyurethane laminate that is constructed to solve certain manufacturing difficulties involved in the production of plastic photochromic lenses is disclosed. The photochromic laminate includes at least two layers of a resinous material and a photochromic polyurethane layer that is interspersed between the two resinous layers and which contains photochromic compounds. The polyurethane layer is formed by curing a mixture of a solid thermoplastic polyurethane, at least one isocyanate prepolymer, at least one photochromic compound, and a stabilizing system.

Abstract: An optical device including an optical substrate including a first surface having a first zone provided with first selective interferential filtering element for selectively inhibiting transmission of incident light based on the wavelength spectrum of the incident light, the first selective interferential filtering being configured to inhibit, at a first rate of rejection, transmission of a first selected range of wavelengths of incident light, incident on the first zone within a first selected range of angles of incidence, wherein the first selected range of angles of incidence is determined based on at least one main line of sight of a user.

Abstract: The present invention relates to ophthalmic and non-ophthalmic systems with blue light filtering and Yellowness Index ranges. UV and IR filtering are also included. Industrial applications are also outlined in the invention.

Abstract: A composite ophthalmic device comprising an ophthalmic structure, means or lens having a photo-shifting material deployed thereon or therewithin so as to up-shift or down-shift the amplitude, wavelength (or both) of incident radiation into the visible wavelength range.

Abstract: Various embodiments of computer eyewear include optical treatments to provide a relaxing, calming, and soothing light environment for the eye. Certain embodiments of computer eyewear include a frame and two lenses. Each lens in these embodiments has optical power in the range from about +0.1 to about +0.5 diopters, and provides spectral filtering characterized by a transmission curve. The transmission curve includes a stop band portion positioned between about 320 nm to about 400 nm, a first plateau region positioned between about 420 nm to about 450 nm, a ramp region positioned between about 470 nm to about 560 nm, and a second plateau region positioned between about 570 nm to about 680 nm.
