The present description provides an eyewear lens attachment assembly that provides easy and secure attachment between a lens in a frame. An exemplary eyewear lens attachment assembly described herein includes a lens having a lens opening proximate a nose region, a frame holder having a frame engagement feature and a retainer engagement feature, and a slidable retainer including an outer surface, an inner surface, and a flanged projection extending outwardly from the inner surface. When the flanged projection is positioned through the lens opening, the retainer is slidable between an engaged position in which the retainer is secured to the frame holder and a disengaged position in which the retainer and frame holder may be separated.

Eyewear lenses for frameless eyewear may include a stiffening member configured to increase the stiffness of the eyewear lens. The stiffening member may be an integral part of the lens and extend along the upper portion of the lens. At least a portion of the stiffening member may extend forward of a corresponding point on the front surface of the lens. The stiffening member may have different dimensions and cross sections, based on, for example, the stiffening enhancement needed and aesthetic considerations. The stiffening member may be designed to improve the moment of inertia of the eyewear lens to a desired value when compared to an otherwise identical lens without a stiffening member. The increased stiffness caused by the stiffening member may also be designed to achieve a target head force on the head of a user when the eyewear lens is integrated into eyewear.

An eyewear basically includes a front frame, a pair of temples, a lens assembly and a pair of engagement members. The front frame has a pair of connecting parts. Each of the temples has one end connected to the front frame so as to be openable and closeable relative to the front frame. The lens assembly has a light transmission part for transmitting light, and a pair of connected parts are respectively connected to the connecting parts at a time of attachment to the front frame, so that the lens assembly can be detachably attached to the front frame. The engagement members are respectively provided to the temples, and are configured to move toward and away from the front frame in association with opening and closing motions of the temples, so that the engagement members are engageable with the lens assembly.

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.
