Abstract: A pair of prescription lenses adapted for use with a near-to-eye display, includes a first lens power region adjusted to a focal distance to focus an image displayed by the near-to-eye display and a second lens power region adjusted to a focal distance substantially the same as the focal distance of the first power region; eyeglasses containing the lens pair; and a method for optimizing the visual acuity of a wearer of prescription eyeglasses when observing an image generated by a near-to-eye display.

Abstract: An eyeglass device configured for use with a smart eyewear near-to-eye display includes a pair of lenses having a prism which directs an eye's gaze of the wearer to a first power region to focus an image displayed by the near-to-eye display of the smart eyewear and a second power region to focus an image outside or beyond the near-to-eye display of the smart eyewear; and a method for optimizing the visual acuity of a wearer of smart eyewear when observing an image generated by a near-to-eye display and an image outside or beyond the near-to-eye displayed image.

Abstract: Disclosed is a lens carrier for a pair of lenses includes an eye-wire semi-embedded into a groove on the edge of each lens and locked to the carrier by hooks on each of the ends of eye-wires which are embedded into the lens edge and a bridge piece extending between and connecting the eye-wires, wherein the bridge piece has a mounting post which can be index mounted to a device so as to adjust the position of the lenses relative to the device.

Abstract: Methods and apparatus for attaching lenses to a frame includes a lens carrier having one or more eyeglass lenses installed in one or more eye wires or rims that partially or completely encircle the lens. The lenses are joined by a nose bridge. The lens carrier includes a nose bridge spacer region and optionally a clamp that reversibly engages a brow bar or frame.

Abstract: An article configured to secure an interchangeable component or components thereon, interchangeable components, and system for securing an interchangeable component or components to an article are disclosed. An embodiment of the system includes an article, locking unit, component support member, and interchangeable component. A tool-less attachment of the interchangeable component to the article enables the interchangeable component to be easily, quickly, and securely attached to an article, moved from one article to another, and replaced with another interchangeable component quickly.

Abstract: Eyewear which is suitable for routine wear and within masks which are sealed against noxious environmental gases or penetration by water is provided by a frame made up of resilient metal parts including wires to provide the frame with a shape, which facilitates the placement of the eyewear on the head of the user while limiting the movement of the eyewear when in use so as to avoid breaking the seal of a mask inside of which the eyewear is disposed when the mask is donned by the user. The eyewear has a lens holding frame for holding lenses adjacent the eyes of the user's head and connected by a bridge across the user's nose.
