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 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 is an optically corrected lens for nonprescription eyeglasses. In a preferred embodiment, the anterior surface of the lens lies on a portion of a first sphere having a first center. The posterior surface of the lens lies on the surface of a second sphere having a second center. The first and second centers are offset from one another to provide a tapered lens. The lens is oriented on the head of the wearer by a frame that maintains the lens in a position such that a line drawn through the first and second centers 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.

Abstract: Disclosed is an optically corrected lens for nonprescription, dual lens eyeglasses. In a preferred embodiment, the anterior surface of the lens lies on a portion of a first sphere having a first center. The posterior surface of the lens lies on the surface of a second sphere having a second center. The first and second centers are offset from one another to provide a tapered lens. The lens is oriented on the head of the wearer by a frame that maintains the lens in a position such that a line drawn through the first and second centers is maintained substantially in parallel to the normal sight line of the wearer. Methods of making the lenses, and eyewear incorporating the lenses, are also disclosed.

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: Disclosed are optically corrected lenses for nonprescription dual lens eyeglasses. Left and right lenses are each vertically and horizontally tapered, and are each characterized by optical centerlines. The lenses are mounted in dual lens eyewear frames with rake and wrap, with the optical centerlines each vertically displaced from the normal line of sight in an as-worn orientation. The vertical displacement corresponds to the degree of rake in a manner resulting in optical correction of the lenses. Lenses are thus provided which have improved optics when mounted in the raked and wrapped as-worn orientation.

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.
