Ophthalmic lenses are described that have a layer, which has a base refractive index, provided on a surface of the lens. The layer includes at least one gradient index optical element. The ophthalmic lens may be a spectacle lens or a contact lens.

A film for applying to an ophthalmic lens is described. The film, or the combination of the film and the ophthalmic lens are designed to prevent or slow the development or progression of myopia. The film has a base refractive index and includes at least one gradient index optical element. Ophthalmic lenses, such as spectacle lenses and contact lenses, that include the films are also described.

There is provided a wearable heads-up display (WHUD) having a glasses frame, which may comprise a front frame and first and second temple arms each coupled to the front frame. At least a portion of the first temple arm may be foldable relative to the front frame at a first interface disposed at a first distance along the first temple arm away from the front frame. Similarly, at least a portion of the second temple arm may be foldable relative to the front frame at a second interface disposed at a second distance along the second temple arm away from the front frame. The first distance may be different than the second distance. The WHUD may also include a light engine and a display optic both mounted to the glasses frame, and used to form an image viewable by a user of the WHUD.

An eyeglass-shaped frame includes: a pair of lens-holding frames configured to hold lenses; a bridge connecting the pair of lens-holding frames; a temple foldably attached at a front end side thereof; a nose pad configured to support a nose in contact; movable lens-holding frames configured to be placed oppositely in front of the lens-holding frames; and a vertical movement unit configured to vertically move each of the movable lens-holding frames.

A method of manufacturing a button-enabled housing assembly includes pre-forming a composite button component or insert having an elastically flexible button membrane that is mounted on a rigid frame, and thereafter molding a housing over the button insert. The composite button insert is formed in a co-molding operation and can include a rigid island in the flexible button membrane for supporting a cosmetic keycap.
