ABSTRACT:
A frame for rimless spectacles is provided which has no protuberances projecting from both surfaces of lenses, provides an improved effective field of view, and can be fabricated with ease. Blind holes are formed in nose- and temple-side edge surface portions of each spectacle lens, respectively. A pin-like projection is formed on each of nose-side and temple-side contact plates, and is inserted and fixed in the corresponding blind hole by using an adhesive.
