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.

A loupe is bonded to a glasses-type holder to be worn around a head of a user. The loupe includes: a tube framework inserted into a hole or a cutout formed in the glasses-type holder and bonded with a UV adhesive; and a lens held in the tube framework. At least a portion at which the UV adhesive is applied in the tube framework is made of a resin not resistant to acetone and is covered with a paint resistant to acetone.

A pair of eyeglasses includes a primary lens, a primary lens frame including upper and lower frame sections, and at least one snap-on unit disposed between the primary lens and the primary lens frame and including upper and lower engaging members respectively provided on top and bottom portions of the primary lens, and upper and lower engaging blocks respectively protruding from the upper and lower frame sections toward the primary lens. The top and bottom portions of the primary lens are removably embedded in the upper and lower frame sections through snapping engagement between the upper engaging block and the upper engaging member and between the lower engaging block and the lower engaging member.

An eyewear device presents, via an image display, an initial displayed image. The initial displayed image has an initial field of view corresponding to an initial head direction or an initial eye direction. Eyewear device detects movement of a user of the eyewear device by: (i) tracking, via a head movement tracker, a head movement of a head of the user, or (ii) tracking, via an eye movement tracker, an eye movement of an eye of the user of the eyewear device. Eyewear device determines a field of view adjustment to the initial field of view of the initial displayed image based on the detected movement of the user. Field of view adjustment includes a successive field of view corresponding to a successive head direction or a successive eye direction. Eyewear device generates a successive displayed image based on the field of view adjustment and presents the successive displayed image.

A head-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.
