Abstract: Eyeglasses include two lenses and a frame unit. Each lens is integrally formed as one piece by injection molding, and includes a lens body, and a nose side protrusion and an ear side protrusion extending oppositely and respectively from two opposite lateral ends of the lens body. The frame unit includes a bridge and two end pieces. The bridge has a bridge body, and two nose side fixing portions respectively formed on two opposite ends of the bridge body and respectively connected to the nose side protrusions of the lenses. Each end piece has a lens connecting end connected to the ear side protrusion of a respective lens.

Abstract: A pair of rimless eyeglasses includes a pair of lenses, a bridge, a bridge fixing unit and an adhesive unit including two UV cured adhesive members. Each of the lenses is formed with an inner through hole. The bridge fixing unit includes a pair of bridge engaging members disposed on the bridge and each having a bridge engaging head, and a pair of bridge fixing members, each of which has a bridge fixing wall and a receiving space. The bridge engaging heads are respectively inserted into the inner through holes. The bridge fixing walls are respectively inserted into the inner through holes such that the bridge engaging heads are respectively and fixedly bonded to the receiving spaces through the UV cured adhesive members, which are disposed in the receiving spaces.

Abstract: A pair of clip-on eyeglasses includes two rims and a bridge device. The bridge device includes a main body and a connecting unit. The main body has first and second end portions, and is formed with a slide groove that extends therebetween and that has a non-circular cross section perpendicular to an extending direction. The connecting unit has a first connecting element having a first rod member connected to one of the rims, and a second connecting element having a slide block member that is slidable and non-rotatable along the slide groove and that has a non-circular cross section perpendicular to the extending direction, a second rod member connected to the slide block member and the other one of the rims, and a resilient member sleeved on the second rod member.

Abstract: A method of manufacturing a rimless eyeglass lens includes: providing a lens-forming mold assembly that Includes first and second molds cooperatively defining a lens-forming cavity, the second mold including a base and at least two pin units mounted on the base, each of the pin units including at least one pin that projects from the base toward the first mold; injecting a molten plastic material into the lens-forming cavity under an injection pressure while maintaining the first and second molds at a melting temperature of the plastic material; and cooling the molten plastic material to form a rimless eyeglass lens having a shape corresponding to that of the lens-forming cavity and being formed with two through-hole units corresponding to the pin units.

Abstract: A pair of rimless eyeglasses includes a pair of lenses, a bridge and a bridge fixing unit. Each of the lenses is formed with an inner through hole. The bridge fixing unit includes a pair of bridge engaging members disposed on the bridge, each of which has a bridge engaging head, and a pair of bridge fixing members, each of which has a bridge fixing wall defining a receiving space. The bridge engaging heads and/or the bridge fixing walls are resiliently deformable. The bridge engaging heads are respectively inserted into the inner through holes. The bridge fixing walls are respectively inserted into the inner through holes such that the bridge engaging heads respectively, detachably and fittingly engage in the receiving spaces to fix the lenses to the bridge.
