A head-wearable device includes a center support extending in generally lateral directions, a first side arm extending from a first end of the center frame support and a second side arm extending from a second end of the center support. The device may further include a nosebridge that is removably coupled to the center frame support. The device may also include a lens assembly that is removably coupled to the center support or the nosebridge. The lens assembly may have a single lens, or a multi-lens arrangement configured to cooperate with display to correct for a user's ocular disease or disorder.

The invention relates to an assembled structure of a main spectacle frame and an assistant lens frame. Sliding slots having fixing parts are disposed on inner sides of the lens frame of the main spectacle frame. Through holes are disposed in front of the lens frame and positioned to correspond to the sliding slots. The assistant lens frame is disposed on the front side of the lens frame of the main spectacle frame. Positioning bumps are protrudingly disposed on inner sides of the assistant lens frame to correspond to the through holes on two sides of the lens frame of the main spectacle frame. Tip holes are disposed on lateral sides of the positioning bumps to be inserted by tip rods for positioning correspondingly.

This invention relates to eyewear capable of floating above the surface in water and thus easy to spot in open bodies of water. This invention further relates to eyewear comprising an arrangement of modular pods to enable sustain floatation above the surface of water. The invention further relates to modular pods for floating eyewear that comprise an impact-resistant structure.

A glasses frame includes a front-frame and two temples (4, 5) connected to the front-frame through hinges which allow the rotation of the temples (4, 5) from a work position substantially perpendicular to the front-frame, to wear the glasses, as far as a home position substantially parallel to the front-frame, to put away the glasses. The front-frame includes two rims (2, 3) for lens support and possibly a bridge (1) connecting the rims and at least a pivoting element (C) apt to allow the mutual rotation by at least 180° of the rims (2, 3) around a rotation axis (X-X) substantially lying in a plane containing the two centres of the rims (2, 3) and perpendicular to the rims. The temples (4, 5) are directly hinged onto the rims (2, 3).

Provided is a super elastic alloy for biological use having a high biocompatibility, good processability and super elasticity, said super elastic alloy being a super elastic zirconium alloy for biological use comprising 27-54 mol % inclusive of titanium, 5-9 mol % inclusive of niobium which is a β phase-stabilizing element capable of stabilizing the β phase of zirconium, and 1-4 mol % inclusive in total of tin and/or aluminum which are ω phase-suppressing elements capable of suppressing the ω phase of zirconium, with the balance consisting of zirconium and inevitable impurities.

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.

A pair of goggles with a lens assembly, a goggle frame, and at least one lens retention shelf is disclosed. The lens assembly includes a lens with a projection extending from the assembly. The goggle frame is made of a first material and has a frame aperture sized large enough to receive the projection from the lens assembly through it. The lens retention shelf is made of a second material harder than the first material and is disposed behind the frame. The first lens retention shelf includes a projection connector corresponding to the projection, the projection connector is aligned with the frame aperture and sized to receive and engage the projection with the goggle frame interposed between the lens retention shelf and the lens.

This golf training device is designed with the head movement of the golfer in mind. It is designed to train the golfer to hold the head steady or in the same place or very close to the same place throughout the golf swing which helps eliminate lateral head movement. The device helps to frame the ball in between the set of blinders and trains the golfer to keep the ball in between the blinders. The device helps to train the golfer from peeking or looking for the flight of the ball prematurely before contact is made with the golf club. The training device comprises a pair of glasses/shades with two blinders that make the golfer focus on the space which includes the ball. The blinders are for both the left side or right side and can be used at the same time or individually. The blinders can be slid back and forth along the arm of the glasses to adjust the desired length for the golfer. The device gives the golfer a frame of reference during the backswing until well after the golf ball is hit. It gives the golfer, no matter the angle he or she holds their head, a constant reference of head movement. In so doing, it allows the golfer to swing more powerfully and more consistently.

There is disclosed a wearable item. The wearable item includes at least one elongate member for supporting at least one attachable element. The elongate member is fabricated from an inner core that is surrounded by at least one outer layer. The at least one outer layer is elastic when strained by application of stress below a first elastic limit. The inner core is elastic when strained by application of stress below a second elastic limit or permanently deformed when strained by application of stress above the second elastic limit.

Techniques for providing eyewear with electrical components are disclosed. The electrical components can provide electrical technology to eyewear (e.g., eyeglasses) without having to substantially compromise aesthetic design principles of the eyewear. Often, the electrical components can be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. In some embodiments, tethered electrical components can be coupled to electrical components in or attached to a pair of eyeglasses. Tethered electrical components, alone or in combination with eyeglass electrical components can be used for a variety of different applications and uses.
