A golfing performance assistance device for performance assistance through range finding and terrain mapping includes a housing. A power module, a microprocessor, a receiver and a memory storage unit are coupled to and positioned in the housing. The microprocessor is operationally coupled to the power module. The receiver is global positioning system enabled. A range finder, which is laser enabled, is coupled to and positioned in a frame of a pair of glasses. A display that comprises at least one eyepiece of the pair of glasses is coupled to the housing. The receiver, the memory storage unit, the range finder and the display are operationally coupled to the microprocessor. The range finder determines the distance between the user and a visualized target. The range finder, receiver and the memory storage unit are coupled to the microprocessor for determining the distance, map and slope to present on the display.

A head mounted image display apparatus including a display section that displays an image, a frame member that supports the display section, and a mounting member that is supported by one end of the frame member and allows the frame member to be mounted on a user's head, wherein the frame member has, at the one end, a first support section that supports the mounting member and a second support section that supports the mounting member in a support scheme different from a support scheme in accordance with which the first support member supports the mounting member.

Provided is a connection structure between a frame and legs of a pair of eyeglasses. A pivoting end of a leg is formed as a rotating shaft; correspondingly a pivoting end of a frame is formed as a rotating shaft base; an upper clip, an intermediate clip, and a lower clip extend from the rotating shaft base of the frame; the intermediate clip is staggered with the upper clip and the lower clip, the rotating shaft of the leg is clamped between the intermediate clip, the upper clip and the lower clip, and the rotating shaft of the leg rotates between the intermediate clip, the upper clip and the lower clip, enabling the leg to fold closed and open. The connection between the frame and the leg is screw-less, providing a simple structure, convenient installation, and comfortable wear.

The present invention discloses a floatable eyeglasses structure. It has an overall density less than or equal to a density of the water and comprises an eyeglasses frame and two temples. Each of the two temples comprises a front temple hinged to the eyeglasses frame, a rear temple and a sealing ring. The front temple or the rear temple has a slot, and the other one has an insertion block for correspondingly inserting into the slot. The sealing ring is further provided between the slot and the insertion block to form a sealed hollow cavity therebetween.

Eyeglasses with replaceable temples, and exemplary mechanisms to attach a frame-connected portion to a replaceable temple portion, are presented. An eyeglass frame can be attached to a hinged metal piece. The hinged metal piece can have a front solid portion and a rear bezel, including a spring and mesa portion. The spring and mesa portion can include a resilient spring material and an upwardly protruding mesa, and can be inserted into a cavity in a temple piece, and locked into place. By providing numerous temple pieces having essentially the same cavity dimensions, the eyeglasses can be used with an assortment of interchangeable temple pieces, which can be changed at will, effectively giving a wearer many looks and styles from the same basic frame, with the same lenses.

This patent application relates to spectacles or spectacle frames with intertwining helix joints and a nose pad portion to facilitate an interchanging of lenses of the spectacles. The helix joint allows the temples to move into a folded position. The nose pad portion provides an access portion for detaching and/or attaching the lenses.

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

The invention relates to a lens exchanging structure. Lens-frame assembling parts of a glasses frame of a main spectacle frame are assembled with lens frames. Intercalating flanges on one sides of the lens frames are correspondingly intercalated by intercalating concave parts of the lens-frame assembling parts. Positioning slots on another sides of the lens frames are inserted by positioning bumps of the fixing parts in sliding slots of the glasses frame. Therefore, when the main spectacle frame or the lens frames are needed to be exchanged, it only needs to fiddle the fixing parts to separate the positioning bumps of the fixing parts and the positioning slots of the lens frames. Then, the lens frames can be removed from the main spectacle frame. The removed lens frames can be assembled with other main spectacle frames having other styles and colors.

Apparatuses, systems and methods for electronic wearable devices such as smart glasses are described. According to one embodiment, a temple assembly forming part of the smart glasses is disclosed. The assembly can include a temple mechanical connection, a battery carrier, a battery, and a temple body. The temple mechanical connection is configured to form an articulated joint at a first longitudinal end portion thereof with a frame of the wearable electronic glasses. The battery carrier is rigidly attached to the temple mechanical connection at a second longitudinal end portion thereof. The battery is mounted on the battery carrier. The temple body comprises a plastics material, and is configured to house the battery and battery carrier and interface with the second longitudinal end portion of the temple mechanical connection. The battery and battery carrier are generally longitudinally aligned along a longitudinal extent of the temple body, and are configured to form at least part of a structural framework for the temple body.

Embodiments according to the present disclosure are directed to, for example, head mounted eyewear (e.g., similar in form to traditional eye glasses) that includes low light vision enhancing and/or additional vision enhancing capabilities (e.g., near-vision enhancing capabilities). For example, in some embodiments, a head mounted housing arrangement is provided that includes an eyepiece adjacent to a wearer's eye, one or more imaging devices (e.g., one or more solid state or other imagers sensitive to light, including low light levels), one or more image generator(s) operatively coupled to the imager(s) (e.g., optically coupled, in electrical communication with, or wirelessly coupled) to receive an output from the imaging device(s), and/or one or more optical elements (e.g., a combination of mirror(s) and/or lenses). The one or more optical elements may place an output of the image generator(s) into a position that is visible to the wearer's eye.
