Abstract: Eyewear for viewing three-dimensional (3D) images is disclosed. In some embodiments, the eyewear can include lenses that include circularly polarizing filters. The right lens can block light that is circularly polarized in a first direction, and the left lens can block light that is circularly polarized in a second, opposite direction. The circularly polarizing filters can be attached to a surface (e.g., the front surface) of a lens body using an adhesive or by lamination. The lenses can have one or more surfaces that conform to the surface of a sphere, a cylinder, or another geometric shape. In some embodiments, the surface of the lens to which the circularly polarizing filter is applied is cylindrical. In some embodiments, the lenses can have a tapered thickness to provide for optical correction of the lenses.

Abstract: Various embodiments of an eyeglass and eyeglass system are provided that can maintain the geometric and optical quality of a lens supported by the eyeglass. The eyeglass can comprise a frame, a support member carried by the frame, and a lens mounting area or groove extending at least partially along at least one of the frame and the support member. The support member can be pivoted, moved, or deflected relative to the frame between a retaining position and an open position. In the open position, the lens can be seated within the lens mounting area. In the retaining position, the support member and the frame retain the lens without exerting deformative forces on the lens. Accordingly, the as-molded geometric and optical qualities of the lens can be preserved.

Abstract: The present invention relates generally to anti-fogging systems used in eyewear, and more particularly to an eyewear system with a stack of peel away membranes positioned on the posterior surface of a goggle lens.

Abstract: Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in a plurality of spectral bands. Each of the plurality of spectral bands can include an absorptance peak with a spectral bandwidth, a maximum absorptance, and an integrated absorptance peak area within the spectral bandwidth. An attenuation factor obtained by dividing the integrated absorptance peak area within the spectral bandwidth by the spectral bandwidth of the absorptance peak can be greater than or equal to about 0.8 for the absorptance peak in each of the plurality of spectral bands.

Abstract: Eyewear, such as a goggle, is provided that can include an anterior module (such as a lens support) and an interchangeable posterior module (such as a faceplate). The anterior module can be adapted to support at least one lens in a wearer's field of view. The posterior module can be adapted to fit against a contour of the wearer's face and can be selectively interchangeable with the anterior module to modify at least one physical characteristic of the eyewear. In some embodiments, the anterior and posterior modules can be coupled by a suspension assembly in order to allow articulation of the posterior module relative to the anterior module for evenly distributing forces against the wearer's face. Further, the anterior module can be rigid for maintaining the lens in an optically-desirable orientation. Furthermore, the goggle can comprise an interchangeable lens mechanism to facilitate interchanging of lenses in the goggle.

Abstract: Eyewear having three-dimensional (3D) viewing capability is disclosed. The 3D eyewear can include eyeglasses and an eyewear attachment configured to attach to the eyeglasses. The eyeglasses can have lens elements that include linear polarizers, and can be worn by the user without the eyewear attachment during everyday use. The eyewear attachment can include auxiliary lens elements that include quarter-wave plates oriented such that auxiliary lens elements of the eyewear attachment and the lens elements of the eyeglasses cooperate to function as circular polarizers. One lens pair can function as a circular polarizer configured to filter out right-handed circularly polarized light, and the other lens pair can function as a circular polarizer configured to filter out left-handed circularly polarized light.

Abstract: Disclosed is an eyewear retention system. In some embodiments, the eyewear retention system retains a lens by using at least one padding structure located between the lens and the lens holder. In some embodiments, the lens can be press fit into the frame and retained by the resulting interference fit. The lens holder, such as an orbital, can fully or partially surround the lens.

Abstract: Disclosed is a contoured metal eyeglass frame. The frame may be injection molded or cast, and may include sculpted, variable cross section eyeglass components. Thus, the present invention combines the design flexibility of injection molded plastic parts with the strength and durability of metal construction.

Abstract: Disclosed is an interchangeable nosepiece system for an eyeglass frame. The nosepieces system can be used to adjust the orientation of a lens on a wearer's face such that the optical centerline of each lens extends in a predetermined relationship with respect to the wearer's actual straight ahead line of sight. The nosepieces are removably mounted onto eyewear and may be customized for the facial geometry of a particular wearer.

Abstract: Disclosed are dimensionally stable eyeglass orbitals, pivotably mounted in an eyeglass frame. In one embodiment, the eyeglass orbitals are investment cast from substantially pure titanium or a titanium based alloy. The orbitals hold the lenses in the as-worn orientation such that the optical centerline of each lens extends in a predetermined relationship with respect to the wearer's theoretical straight ahead line of sight.

Abstract: A goggle is provided with double unitary lenses, separated by an insulating space to reduce fogging. At least one of the lenses is tapered to reduce prismatic distortion through the lens in an as-worn orientation. In an exemplary goggle, the tapering of one lens compensates for prismatic distortion and/or astigmatism introduced by the other of the lenses. The lenses are mounted in a goggle frame in a predetermined orientation with respect to a wearer's normal lines of sight. In one embodiment, the optical centerline or axis of the double lens system is aligned to be parallel with the wearer's normal lines of sight in the as-worn orientation. Method of manufacturing such lenses is also provided. The illustrated goggle defines an enclosed space between the inner lens and the wearer's face when worn, but includes ventilation to the enclosed space to allow moisture to escape.

Abstract: Disclosed is an optically corrected shield for unitary lens eyeglasses or safety helmets. The shield is characterized by an optical centerline and a mechanical centerline, which intersect each other at an angle. The lens is oriented on the head of the wearer by a frame or helmet that maintains the lens in a position such that the optical centerline is maintained substantially in parallel to the normal sight line of the wearer. Lenses are thus provided which have improved optics when mounted in an as-worn orientation such that they exhibit both vertical "rake" and horizontal "wrap." Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.
