According to the connecting structure of the present invention for a frame and a lens, a female screw projection provided at an end of the frame is inserted into a hole provided in the lens, and a male screw is screwed into the female screw projection. By preventing the frame and the lens from separating from each other, a substantial connection between the frame and the lens becomes possible, and a hole is formed in a portion of the lens corresponding to the hole provided in the frame, By fixing the fixing member over the holes to prevent the frame and the lens from rotating, it is possible to improve the stability of the connection state between the frame and the lens. Can be reliably and easily prevented from relatively moving the frame and the lens. Here, the female screw protrusion is provided on the frame, and if the outer diameter of the female screw protrusion provided on the frame corresponds to the inner diameter of the hole provided on the lens, the corresponding surface is slidably contacted. When inserting the female screw protrusion of the frame into the hole of the lens, it is not always necessary to interpose a sleeve etc., and the female screw protrusion inserted into the hole of the lens is maintained at a predetermined position, and the insertion state is stabilized. Can be done. In addition, as this frame, each component frame in an eyeglass frame such as a bridge, armor, temple, or the like can be cited. If a pin is used as the fixing member, the frame and the lens can be prevented from rotating relative to each other over the frame and the lens. If a flange is provided so as to protrude from the outer periphery of the pin in the middle in the longitudinal direction, the flange can be sandwiched between the frame and the lens, and the pin can be prevented from falling off. If a male screw is used as the fixing member and at least one hole of the frame and the lens in which the male screw is provided is threaded and drilled into a female screw shape matching the male screw, the frame and the lens can be straddled. It can be reliably arranged.

Further, in the method for connecting a frame and a lens according to the present invention, in a state where the frame and the lens are temporarily assembled, prior to forming a hole in a lens portion corresponding to a hole provided in the frame, The desired positional relationship is selected by adjusting the positional relationship (mounting angle) between the frame and the lens while rotating the frame and the lens relatively, and the position of the hole to be drilled in the lens according to the selected positional relationship. Can be determined. Another connection method of the present invention, in a state where the frame and the lens are assembled, prior to drilling a hole in the lens portion corresponding to the hole provided in the frame,
While rotating the frame and the lens relatively, the positional relationship (mounting angle) between the frame and the lens is adjusted to select a desired positional relationship, and the holes to be drilled in the frame according to the selected positional relationship. The position can be determined. In any connection method, the outer diameter of the female screw protrusion is made to correspond to the inner diameter of the hole of the lens into which the female screw protrusion is inserted, so that the female screw protrusion provided on the frame and the female screw protrusion are inserted. The holes provided in the lens to be slidably come into contact with each other and do not necessarily require an intervening member such as a sleeve, and the female screw protrusion of the frame inserted into the hole of the lens is inserted and maintained at a predetermined position. The state can be stabilized. In particular, by integrally forming the female screw protrusion on the frame, the number of components can be reduced and the connection work between the frame and the lens can be simplified.
