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.

Interchangeable single-lens glasses include a mount with a front lens-holding frame having a bar extended at supraciliary arches between opposed lateral ends of the frame, and means for removable retention on the bar a single-lens structure extending frontally between the ends. The means for retaining the lens structure on the bar include, at each of the lateral ends, at least a respective first magnet or ferromagnetic material element provided on the frame and a second magnet or ferromagnetic material element provided on the lens in a corresponding position, to cooperate in reciprocal magnetic attraction with the corresponding first element, and, at a central portion of the bar, proximate to a nasal rest area of the mount, a relief protruding frontally from the bar and an opening passing through the lens in a corresponding position, the relief being configured to engage the opening with relative reciprocal locking.

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.

User configurable eyeglasses employing retention of lenses in eyeglass frames using elastic cushion connectors may include a pair of lenses, each lens comprising at least one tab extending from the lens. An eyeglasses frame may define at least two fittings, each fitting positioned to receive one tab extending from a lens and each fitting sized larger than the tab to be received. A plurality of eyeglass lens retention cushions are each adapted to be disposed in one of the fittings and to receive one of the tabs. Each eyeglass lens retention cushion might have an elastic cushion body having a relaxed, or in situ, exterior size larger than an interior socket of the fittings and may have an interior opening with a relaxed, or in situ, size smaller than a tab extending from an eyeglasses lens.

A flip-to-wear eye shield system is provided. By integrating a hinge into elements of the frame and/or the lens, the eye shield can be manufactured and assembled more quickly and with less costs. In an embodiment, a lens may click (or snap) onto molded posts of a frame in a substantially flat position. An integrated living hinge in the frame may bend to allow the lens to flip downwards toward the frame to a second position for use. The posts may also click (or snap) into place in an underside of the frames. In another embodiment, a lens may click (or snap) onto molded posts of a flame in a substantially flat position. An integrated living hinge, formed by notches in the lens, may allow the lens to bend to flip downwards to the frame to a second position for use. A dispenser allows storing the eye shields in the flat position and dispensing in the second position for use.

A pair of glasses includes a spectacles frame, a lens unit, and two pivotal members. A pivot hole is provided in each of first and second ends of the spectacles frame. The lens unit is detachably assembled on the spectacles frame and includes two snap-fit portions. Each pivotal member includes a swing arm and a pivot formed at the swing arm and held in a corresponding pivot hole, so that each pivotal member can make a pivotal rotation relative to the spectacles frame. The swing arm includes a locating slot at a lower end thereof. The lens unit is assembled on the spectacles frame when the snap-fit portions of the lens unit join the locating slots in the pivotal members. The lens unit can be disassembled from the spectacles frame when the snap-fit portions of the lens unit are separated from the locating slots in the pivotal members.

Disclosed is a modular pair of spectacles, including a frame which includes a rim and two temples mounted in connection with the side ends of the rim. The rim is provided with an upper portion, a lower portion and assembly unit between the portions. The upper portion includes at least of the side ends thereof a first longitudinal semi-connection portion and the lower portion includes at each of the side ends thereof a second longitudinal semi-connection portion. The first and second longitudinal semi-connection portions complement one another and are configured such that, upon assembling the upper portion and the lower portion, the first and second portions form a first female or male connection unit, configured to receive a second male or female connection element, arranged at the end of each respective temple. Aldo disclosed is a kit for forming such a pair of spectacles.
