Glasses include a glass upper frame, a glass lower frame, the lens, and a bridge. Each of two ends of the glass upper frame dents to form a downward-opening receiving cavity of predetermined depth. Each of two ends of the glass lower frame dents to form a receiving cavity of predetermined depth. Magnetic elements are fitted snugly into the receiving cavities. An elevated portion is centrally disposed at the glass lower frame and corresponds in position to a slot dentedly-formed at the bridge such that a complete stop groove is formed along the glass lower frame when the bridge is fitted to the glass lower frame. The bottom edge of the glass upper frame dents to form a groove. Each of the two ends of the glass upper frame dents to form an inward-opening dented portion. The groove, dented portions, stop groove, and bridge jointly hold the lens.

An electronic frame for an optical device, the frame including a front frame element able to partially house at least one lens and including at least one electronic component, the front element extending, on either side of said at least one lens, over a retained length of said at least one lens. The front element includes a reinforcing element extending at least substantially over all said retained length of said at least one lens.

An eyewear device has a lens retention mechanism that establishes electrical contact between onboard electronics and a lens ring by a resiliently compressible electrical contact member, such as a spring washer, located within a housing defined by a body of the eyewear device. The retention mechanism can further include a lock screw that is selectively engageable with the lens ring to allow disposal between retention and release of a lens by the lens ring, the lock ring being captured in the housing such as to resist removal of the lock screw from the housing when the lens ring is released for lens removal.

A pair of eyeglasses includes a front with two lenses installed in the two openings thereof. Two lugs respectively extend from two ends of the front and each have a slot communicating with the opening corresponding thereto. Two threaded holes are respectively defined through the two ends of the front and communicate with the two slots. Two screws threadedly extend through the two threaded holes to narrow the slots to secure the two lenses in the front. The two lugs are clamped between the two connectors and two securing members by bolts extending through the securing members, the lugs and the two connectors, and connected with two positioning members. The lenses can be replaced by unscrewing the bolts and the screws.

An optical device for a wearer including an optical system with an active function configured to be mounted into a frame, a wafer comprising an internal face facing the optical system, the wafer being configured to be mounted into the frame, and holding means configured to maintain the optical system and the wafer in the frame without contact at least between a part of the optical system and the internal face of the wafer.

A lens interchange mechanism for an eyewear may include a magnetic latch operatively associated with the eyewire of the eyewear, such that the a portion of the eyewire can be released, with a free end separating from another portion of the eyewire thereby forming a gap in the eyewire for the removal and installation of a lens. The magnetic latch mechanism may be further configured for easy re-latching by the application of opposing forces on the first and second eyewire portions to cause the free end to re-engage with the magnetic latch without manual actuation of the latch.

Interchangeably lenses and attachment assemblies for eyewear with removable temples are described. An example attachment assembly for removably magnetically attaching an eyewear temple to a lens may include a magnetic latch having a first latch portion and a second latch portions movably (e.g., pivotably) coupled to the temple. The first and second latch portions may be configured to be positioned on opposite sides of the lens by a carrier. The first and second latch portions may be configured to magnetically attract one another in a magnetic attraction direction. The carrier may be configured to restrict movement of at least one of the first and second latch portions in a second direction opposite the magnetic attraction direction.

An eyeglass frame is disclosed comprising a bridge and two rims connected by the bridge. Each rim is configured to contain a lens. The eyeglass frame also comprises two split end pieces. Each split end piece comprises a first portion and a second portion. Each split end piece is coupled to and extends outward from a corresponding rim of the two rims on a side of the corresponding rim opposite the bridge. The eyeglass frame further comprises two temples. Each temple comprises a lock on an end of the temple. The lock is configured to at least partially contain both the first portion and the second portion of the split end piece and secure the temple to the corresponding rim and secure the lens within the corresponding rim.
