摘要 PCT No. PCT/JP94/02148 Sec. 371 Date Mar. 6, 1995 Sec. 102(e) Date Mar. 6, 1995 PCT Filed Dec. 20, 1994 PCT Pub. No. WO96/05535 PCT Pub. Date Feb. 22, 1996The technical issues of the present invention are to provide a pair of the rimless spectacles whose right-and-left lenses can be mechanically simply interlocked and held in a stable condition by means of three points supporting system with simple metallic holding parts and also which is easy to correct an error of locking holes bored in the lenses, and if necessary, further to provide a pair of the rimless spectacles which is fittable to those eyeglasses wearers whose right-and-left eyes are narrow in distance and whose face is wide in breadth and which is also adequate for P.D. (pupil distance) standard. To solve those issues, the present invention has adopted such technical means as the bridge made of metallic material constituted by having two bars of the inner rim pad portion running in parallel capable of making a line contact with the inner edge portion of the right-and-left lenses and the inner going-through portion to be poked through the bridge locking hole bored in the lenses nearer to the inner edge portion thereof as well as the bracket endpiece made of metallic material constituted by having two bars of the outer rim pad portion running in parallel capable of making a line contact with the outer edge portion of said lenses and the outer going-through portion to be poked through the endpiece locking hole bored in the lenses nearer to the outer edge portion thereof, and it is characterized in that a pair of the right-and-left lenses are symmetrically juxtaposed by interposing and interlocking them by means of such three points supporting system as mentioned above.
