A pair of eyeglasses includes a primary lens, a primary lens frame including upper and lower frame sections, and at least one snap-on unit disposed between the primary lens and the primary lens frame and including upper and lower engaging members respectively provided on top and bottom portions of the primary lens, and upper and lower engaging blocks respectively protruding from the upper and lower frame sections toward the primary lens. The top and bottom portions of the primary lens are removably embedded in the upper and lower frame sections through snapping engagement between the upper engaging block and the upper engaging member and between the lower engaging block and the lower engaging member.

The multiuse eyeglasses include a frame that holds two lenses and arms that extend from the frame. The arms include a first axis of rotation that is generally perpendicular to the arms and a second axis of rotation that is orthogonal to the first axis of rotation and allows the arms to be rotated downwards relative to the frame.

Eyewear having a frame, a hinge, and a hyperextendable temple. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. A cam is configured to leverage the temple away from the frame during hyperextension and reduce wear. A cosmetic trim may include a recess that receives a protrusion of the frame in the open position, and which protrusion moves out of the recess during hyperextension and creates the cam.

A set of customizable eyeglasses allows customers to make adjustments to a width of eyeglass frames relative to one another, a width of eyeglass temples relative to one another, a depth of eyeglass temples from the eyeglass frames, and/or a length of the nose bridge support from the customer's face. The customer could input one or more measurements into a system, such as a width and depth of a face, and a company could manufacture the eyeglass components in accordance with the measurements to provide rough adjustments to the eyeglasses to be sent to the customer. When the customer receives the eyeglasses, the customer could then make fine adjustments to the eyeglasses to further customize the fit.

A combined glasses structure, including a lens component, two temples, a frame component and a nose pad component is provided. The lens component comprises two lens and a bridge, two temples are respectively detachably connected to the lens component; the frame component includes an upper frame and a lower frame, the upper frame and lower frame are respectively detachably arranged on an upper and a lower edge of the lens component; the nose pad component and the bridge are detachably connected to each other, and can restrict and fix the upper frame and/or lower frame arranged on the upper edge, lower edge, upper and lower edges of the two lens. By the detachable connection between the frame component and the lens, the frameless, half-frame (upper frame or lower frame) and full-frame functions of the combined glasses can be achieved.

An anti-slip eyewear system comprising a nosepiece configured to couple to a bridge of an eyewear frame, the nosepiece comprising a core comprised of a first material and an outer layer at least partially surrounding or overlapping the core and comprised of a second material, the second material having a lower durometer than the first material, wherein the second material creates a plurality of Schallamach waves on an outer surface of the nosepiece when the outer layer of the nosepiece is in contact with at least a portion of a face of a user. The first material may have a durometer greater than about Shore 40A on the Shore A hardness scale and the second material may have a durometer less than about Shore 40A on the Shore A hardness scale.

An eyewear system comprising an eyewear frame comprising a first side bow component and a second side bow component, an auxiliary frame comprising an auxiliary top bar, an auxiliary first side bow component and an auxiliary second side bar component, the auxiliary first side bow component and the auxiliary second side bow component pivotally coupled to the first side bow component and the second side bow component, respectively. The system further comprises a declination angle adjuster positioned proximal a bridge of the eyewear frame, the declination angle adjuster comprising a rotatable member therein, and a vertical extension member extending from the eyewear frame and at least partially into the declination angle adjuster, the vertical extension member configured to engage the rotatable member within the declination angle adjuster.
