A pair of full frame glasses is revealed. A through hole and a mounting fixing hole are penetrating an upper frame portion and a lower frame portion of a frame respectively while an upper mounting wall is formed behind the through hole and a lower mounting wall is formed behind the mounting fixing hole. A fixing member includes an elastic positioning piece and an elastic mounting portion capable of being inserted through the through hole and the mounting fixing hole. An upper mounting projection corresponding to a lower edge of the upper mounting wall and a lower mounting projection corresponding to a lower edge of the lower mounting wall are projecting from the elastic positioning piece. Thereby the upper and lower frame portions are connected securely by the fixing member. During assembly and disassembly processes, no tool is required so that the glasses are more convenient to use.

Eyeglass frames include a face member and two temple members connected to the face member. The face member includes a rim with a brow configured to retain at least one lens. A nose member is connected to the face member and supports the rim separated from a face of a wearer by a gap. A vent passage is provided in the brow and extends from a front portion of the brow to a rear portion of the brow. A vent adjustment member provided on the brow directly above the at least one lens. The vent adjustment member is configured to move between a first position wherein the vent passage is substantially closed and a second position wherein the vent passage is open. The vent adjustment member is substantially flush with a medial portion and a lateral portion of the brow when the vent adjustment member is in the first position and offset from the medial portion and lateral portions of the brow when the vent adjustment member is in the second position.

An eyewear device having a frame positionable to a removable engagement with any of a plurality of lens assemblies. Each lens assembly has shoulders at opposing ends which slidably engage within respective shoulder slots formed into the body of the frame. A biased ball having a portion extending into one or both shoulder slots, biasly contacts into a ball cavity depending into a respective shoulder to maintain the lens assembly in the removable engagement.

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 optical element includes an optical lens produced by an additive manufacturing method and a holder formed at least in part with the optical lens by the additive manufacturing method. The holder is adapted for cooperation with a manufacturing machine to thereby position the optical lens at a predetermined position in the manufacturing machine. A corresponding assembly and a method of manufacturing an optical element are also described.

An optical part (10) comprises an ophthalmic lens (11; 12) produced by additive manufacturing and a holder (14) integrally formed with the ophthalmic lens (11; 12). A method of producing an optical part is also disclosed.

An eyeglass frame each has a plurality of first magnets located at each eye section and a pair of lens, each having a plurality of second magnets, able to be removably connected to the first magnets. This provides a way to removably attach an individual lens to a corresponding eye section of the frame.
