An eyewear frame of improved comfort, including a one-piece non-folding eyewear frame to which a shield is attachable to provide eyewear, the frame being made of plastic having a flexural modulus of from about 250,000 psi to about 310,000 psi (ASTM D790A), with the frame having a brow piece and a pair of symmetric left and right ear pieces extending away from the brow piece at opposite ends of the brow piece, each ear piece terminating at a free end, with the free ends of the brow pieces being spaced apart from one another to define a gap, with the frame having a maximum width such that the ratio of the maximum width to the gap is above 3.

An eyeglasses assembly includes a frame and a lens. The frame includes a frame body formed with a frame groove and two engaging grooves, and a positioning column disposed in the frame groove. The lens has a main portion formed with a lens groove and a securing groove that extends perpendicularly from the lens groove. The lens further has first and second protruding portions engaging removably and respectively with the engaging grooves. The lens is movable between an initial position, where the positioning column is disposed at an intersection of the lens groove and the securing groove, and a fixed position, where the positioning column is disposed at a distal end of the securing groove such that the second protruding portion is allowed to be disengaged from the respective engaging groove.

An object of the present invention is to provide a thin and lightweight polarizing lens for use in lightweight sunglasses (in particular, rimless sunglasses) while maintaining the clamping force and mechanical strength of a temple part, and a manufacturing method therefor. The values of: the center thickness v of a polarizing lens A including an injection-molded layer 3 laminated on at least one surface of a polarizing sheet B, the injection-molded layer having a polyamide-based resin; and the flexural modulus of the injection-molded layer 3 are adjusted, thus the predetermined clamping force and mechanical strength of a temple part are obtained even in the case of sunglasses with the thin and lightweight polarizing lens.

Eyewear can include lenses having perimeters that are customized for an intended wearer. The perimeter of the lenses can be determined based on anatomical features of the wearer's face, the wearer's field of vision, or other parameters specific to that individual. Determination of the lens perimeters can involve developing a three-dimensional model of a wearer's face and/or head, demarcating a lens perimeter over an obtained image of a user's face, or delineating the boundary of a wearer's peripheral vision. A provisional lens perimeter obtained by any of these methods may be modified in curvature and/or size to arrive at a desired final lens perimeter. Customized lenses can be fabricated based on the determined lens perimeters. The customized lenses can be assembled into completed eyewear that is customized for a wearer, for example having shapes, sizes, and designs not otherwise possible.

Eyeglasses with simplified hinge include a pair of lenses, a pair of temples and a hinge for connection between each one of the temples and the lenses. The hinge includes an element for connecting the lens and the temple, adapted to be connected to the lens at one end and provided, at an opposite end, with a portion adapted to engage a retention and locking element. The temple is provided with a cavity adapted to accommodate and lock the retention and locking element, the retention and locking element acting as a rotation fulcrum for the temple with respect to the connecting element.

An eyeglass lens replacement assembly is revealed. A frame includes a lens insertion slot disposed on a lower edge and a mounting indentation communicating with the lens insertion slot. A bevel is formed on each of two sides of the front end of the mounting indentation. A movable mounting member is mounted in the mounting indentation and has two mounting pins and a concave part formed on a middle part of the mounting pin. The upper edge of a lens is inserted into the lens insertion slot while the lens includes a mounting slot corresponding to the mounting pins and two protruding portions corresponding to the concave parts of the mounting pins. The movable mounting member can turn back and remain positioned by the bevels of the mounting indentation combined with recovery elasticity of the two mounting pins of the movable mounting member. No additional elastic members are required.

A system of attaching auxiliary lenses to a pair of eyeglasses. One auxiliary lens can have one, two, three or more magnets embedded therein, and one of the eyeglasses in the pair of eyeglasses could have a corresponding one, two, three or more magnets embedded therein which would have their polarity configured such that the auxiliary lens would fit over and remain attached to the eyeglass.
