An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.

Glasses have a groove provided in a vertical direction on a bridge of a glasses frame. A support section of a nose pad of the glasses is connected to an end portion of a positioning section of the nose pad, the positioning section is slidably disposed in the groove, and the positioning section has a plurality of locking slots and a limiting slot. An adjustment mechanism of the glasses is disposed at the glasses frame, and a pressing member of the adjustment mechanism is disposed perpendicular to the groove, where one end of the pressing member protrudes from one side of the groove, and the other end penetrates through the groove and the limiting slot. A positioning member of the adjustment mechanism is connected to the other end of the pressing member. The positioning member moves from a positioning position to a release position by pushing of the pressing member.

An adjustable nose bridge includes a mounting body and a nose bridge frame. The nose bridge frame includes a main body, an elastic member, and an adjusting member. Two ends of the elastic member respectively resiliently abut the main body and the mounting body. The adjusting member is telescopically coupled to the mounting body and fixes a position of the main body.

A nose pad adjustment assembly is revealed. The nose pad adjustment assembly includes two nose pad blocks and a nose pad base which consists of a recess portion and two connection portions located at two sides of the recess portion correspondingly. The connection portion has an upper locking hole and a lower locking hole. The nose pad block includes an upper protrusion and a lower protrusion respectively movable transversely in the upper locking hole and the lower locking hole correspondingly. The upper and the lower protrusions are respectively provided with a plurality of upper and lower locking grooves which are able to be engaged and connected with the upper and the lower locking holes correspondingly. Thereby the nose pad blocks can be adjusted for close fit to user's nose bridge. Therefore, glasses are positioned without sliding freely and users feel more comfortable while wearing the glasses.

A device for protecting a user's nose from solar radiation has a cover part which is formed to cover a user's nose and is composed of a material which is capable of protecting a user's nose from solar radiation, and a connecting part which is attachable to glasses or sunglasses wearable by a user and formed to be retained on the glasses and holds the cover part of the device on the user's nose.

The invention relates to eyeglasses having two lens units that are fitted with a device for keeping the eyeglasses on a wearer's head. The eyeglasses having a nose bridge that connects the two lens units and includes a central portion to be disposed about the wearer's nose At least one of the lens units has a duct inside to which a lateral portion of the nose bridge is slidingly mounted using a mechanism for adjusting the position of the lens unit relative to the nose bridge. The adjusting mechanism has a member that is rotatably mounted in the duct. The member and the lateral portion of the nose bridge comprise a coupler designed to convert the rotation of the member into a relative translational movement between the lateral portion and the duct.

A glasses frame includes: a pair of lens-holding frames each holding vertically arranged lenses; a bridge coupling the lens-holding frames in height at the center; a temple; an inverting unit provided on an outside and in height at the center of each of the lens-holding frames and configured to invert the temple; and nose pads provided correspondingly one-to-one to both ends of the bridge and supporting the bridge while being in contact with a nose even when the lens-holding frames are inverted, in which the temple includes a bent portion.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Eyewear is disclosed that can have multiple ventilation states providing different amounts of ventilation through the eyewear. The eyewear can include a lens and a frame. In some embodiments, the lens and/or frame can be moved with respect to the user to provide the multiple ventilation states. In some embodiments, the eyewear can include a nosepiece which is movable from at least a first configuration to a second configuration to provide the multiple ventilation states.

A system having a nose pad assembly that is configured to removably attach to an eyeglass frame and provide support to the eyeglass frame; an attachment base part with a front side and a backside; a first attachment portion disposed on the backside of the attachment base part is configured to engage a portion of said eyeglass frame; a second attachment portion disposed on the front side of said attachment base part is configured to removably engage the nose pad assembly; and a linkage framework that is configured to removably engage the nose pad assembly with the eyeglass frame via the second attachment portion.
