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.

The present invention discloses novel rimless glasses which include a left temple, a left end piece, a left lens, a nose mid-bridge, a right lens, a right end piece and a right temple. A first lens fixing device is disposed between the left end piece and a left end of the left lens. A second lens fixing device is disposed between a right end of the left lens and a left end of the nose mid-bridge. A third lens fixing device is disposed between a right end of the nose mid-bridge and a left end of the right lens. A fourth lens fixing device is disposed between a right end of the right lens and the right end piece. The rimless glasses have a reasonable simple structure design, a reliable connection, not easy looseness, ease of assembly and disassembly, convenient maintenance, and achieves a reinforcement effect on the lenses.

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.

Eyeglasses include a frame having a frame main body defining a receiving slot, a fastener having a rectangular body segment exposed from the receiving slot, and a lens unit including two lens portions and a connecting portion having a receiving notch. The fastener is rotatable at a predetermined angle relative to the frame between a first position, in which the lens unit can be inserted into or removed from the rectangular body segment through an opening of the receiving notch and can be inserted into or detached from the receiving slot through the lens portions; and a second position, in which the rectangular body segment is received and retained in the receiving notch, and the lens unit is fastened to the frame.

Lenses may be mounted to eyewear using several techniques. A first technique involves the use of a lens unit that is mounted to a frame at a frame bridge. The lens unit includes a lens frame split proximate to the frame bridge, allowing the frame to be opened and a lens inserted. A second technique involves a mechanical interference arrangement that allows a lens to be inserted into, and retained by, a frame groove in a front frame. An inner cover may then be affixed to the front frame to enclose electronics in the front frame.

An ophthalmic lens fastening consists of a structural part and a sleeve. The sleeve is slidable into an elongated hole of an ophthalmic lens, and one end of the structural part is slidable into the sleeve such that a latching connection with a press fit is formed.
