Methods for supporting a development of application source code using input from a first smart glasses of a first user and a second smart glasses of a second user is provided. Methods may include retrieving the application source code from an internal development platform and displaying the application source code on an augmented reality (“AR”) display of the first smart glasses and an AR display of the second smart glasses. Methods may include receiving, from the first smart glasses, a command to edit the application source code and in response, deactivating each input device of the second smart glasses. Methods may include receiving input of one or more edits on the first smart glasses and updating the application source code to include the input. Methods may include displaying the updated application source code on the AR displays and reactivating each input device of the second smart glasses.

A head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated image towards eye boxes for viewing by a user. The optical system may be a see-through optical system that allows the user to view a real-world object through the optical system while receiving the computer-generated image or the optical system may include a non-removable lens and a removable vision correction lens through which an opaque display is viewable. The optical system may include a removable lens. The removable lens may serve as a custom vision correction lens to correct for a user's vision defects. The optical system may have a projection bias lens that places computer-generated content at one or more desired virtual image distances and a corresponding compensation bias lens.

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.

A visual perception device is described. The visual perception device has corrective optics for viewing virtual and real-world content. An insert for the corrective optics is attached using a magnetic set, pins and/or a nose piece. Interchangeable nose pieces allow for height adjustments to accommodate different users. The visual perception device has pliable components to absorb forces exerted on a nose piece and a protective barrier for limiting electric shock or ingress of dirt.

The present disclosure provides a head mounted display that comprises display lenses, a frame body and at least one magnetic attraction part. The display lenses are configured to display augmented reality or virtual reality image content. The frame body comprises a carrying part configured to carry the display lenses. The at least one magnetic attraction part is disposed on the frame body and configured to magnetically attract a first lens unit or a second lens unit, so that the first lens unit or the second lens unit is attached to the frame body. The first lens unit comprises first magnetic elements, and the second lens unit comprises second magnetic elements.

An optical attachment for surgical loupe glasses is disclosed. The optical attachment for surgical loupe glasses includes a visor sized to cover at least a portion of a first carrier lens of the surgical loupe glasses. The optical attachment also includes at least one loupe orienting feature defined by the visor.

Disclosures of the present invention describe a device for measuring retina safety improvement index, comprising: a light receiving unit, a first data processing unit and a second data processing unit. The light receiving unit receives a first visible light and a second visible light that is obtained by letting the first visible light pass through a blue light blocking product. The first data processing unit calculates a first maximum permissible exposure (MPE) of the first visible light and a second MPE of the second visible light. The second data processing unit calculates a retina safety improvement (RSI) index based on the first MPE and the second MPE. As such, by using this device, a consumer is facilitated to know how much eyes-protecting ability does a specific blue light blocking product have, without needing to read any numeric value of blue light filtering percentage and/or unfamiliar spectrogram.

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.
