A dismountable frame for glasses comprises a frontal chassis (2) having a pair of circles (3, 4) for housing respective lenses, a pair of rods (5, 6) mounted laterally to the chassis (2) from opposite sides with respect thereto, means for removably fixing the rods (5, 6) to the chassis (2) comprising a pair of end pieces (8) each having a first shaped portion (9) with jointing means (10) adapted to be removably inserted and fitted in corresponding counter-shaped lateral seats (11) of the chassis (2), the latter being provided with a pair of through cuts (12, 13) made in each of the lateral counter-shaped seats (11) to allow the enlargement of the circles (3, 4) in the absence of the end pieces (8).

Techniques for providing eyewear with electrical components are disclosed. The electrical components can provide electrical technology to eyewear without having to substantially compromise aesthetic design principles of the eyewear. The electrical components can be partially or completely internal to eyewear. The electrical components can also be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. Apparatus for presenting after-market electrical components are also disclosed.

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.

In one embodiment, an eyeglass frame includes a lens holder, a first temple with a first end close to the lens holder and a second end, a second temple, an electrical connector and a printed circuit board. The printed circuit board with at least one electrical component can be in the first temple. The connector can be close to the first end of the first temple, facing downward, and electrically connected to the at least one electrical component. In another embodiment, an eyeglass frame includes a first printed circuit board, with at least one electrical component. The first printed circuit board can be connected to an electrical component at the frame via a second printed circuit board.

Disclosed is eyewear including: a lens unit comprising a lens; a detachable frame detachably coupled to the lens unit at both left and right ends of the lens unit with respect to a user; a temple arm coupled to one end of the detachable frame and fitting over the user's ears; and a connecting member disposed between the detachable frame and the eyeglass temple to connect the detachable frame and the eyeglass temple.

A frame for an eyewear comprises a lens opening and a groove surrounding the lens opening. The lens opening may be defined by an upper frame portion, a lower frame portion, a first lateral side portion, and a second lateral side portion of the frame. The groove may interchangeably receive and secure a first lens and a second lens within the lens opening. The first lens may have a different thickness than the second lens. The lens opening may extend across both eyes of the wearer.

A vented eyeglass frame is provided having a front frame extending laterally from a first end to a second end and for connecting to a temple at each of the first end and the second end. The front frame has first and second lens openings, with each lens opening being defined by a respective opening boundary at least partially circumscribing the corresponding lens opening. A bridge is defined between the first and second lens openings, and outer vents are provided at each end adjacent the corresponding lens openings. Inner vents are then provided at the bridge adjacent the lens openings. The lens opening boundaries each have a lens channel for at least partially enveloping a lens located at the respective lens opening, and each vent is defined by a gap in the corresponding lens opening.

Devices providing adjustable optical power have previously been proposed for use as corrective lenses in prescription eyeglasses. There is disclosed a lens having optical power adjustable by relative lateral translation of two lens elements, the lens comprising: a first lens element sealed to a cover to define a cavity therebetween; a second lens element disposed within the cavity and coupled to an elongate drive element extending laterally from the second lens element, the second lens element being arranged to be driven laterally relative to the first lens element by lateral translation of the elongate drive element to thereby adjust the optical power of the lens, the lens comprising a lateral projection into which the cavity and drive element extend, the lateral projection having there mounted an adjuster for driving lateral translation of the elongate drive element. The lens reduces or prevents the ingress of dirt, moisture, sweat and grease between surfaces of the lens elements. There is also disclosed an eyeglasses frame, such as may be particularly suited to said adjustable power lens.

An eyeglass lens includes an outer surface, an inner surface, and a perimeter edge. The perimeter edge includes at least one lower portion, and/or at least one outer side portion and/or at least one inner side portion and/or at least one upper portion. It is foreseen for there to be an optical axis of the lens that joins the centres of curvature of the outer surface and inner surface. In any section plane passing through said optical axis, at least one from said outer side portion, inner side portion, lower portion and upper portion of the perimeter edge is inclined, with respect to the optical axis, by a predetermined acute angle. The predetermined acute angle is selected so as to minimise the extension in width of at least one of the projections of the portions on the retina of the eye of the user.

A method for fitting spectacle lenses into full rim spectacle frames, comprising machining the edge of the spectacle lenses to be fitted, wherein, a circumferential, step-like chamfer with a curvature determined as a section of a sphere surface with a defined radius is worked into the spectacle lens holders in the full rim spectacle frame on the front or back side, then the edge of the spectacle lenses is machined, in the form of a front-side or back-side circumferential step-like bevel with a curvature determined according to the sphere surface with a defined radius of the chamfer. The spectacle lenses are fitted into the holders in the full rim spectacle frames on the front or back side, with precise engagement of the bevel into the chamfer of the spectacle frame, and the inserted spectacle lenses are adhesively bonded and/or welded to the holders in the full rim spectacle frame.
