Abstract
Clamping mechanism of spectacle lens is provided, which does not involve any complications in assembly, but allows the spectacle lens to be held in place with facility and renders the spectacles smart and shapely in design. A pair of glasses or a lens is stably and accurately supported in front of the eyes by poking the projections provided to either the front bar or the rim frame to support the same through at least two points of the same for clamping. The facility of clamping the lens or lenses allows the labor for the assembly of the spectacles to be lightened as well as the production cost thereof to be reduced, which facility also renders the spectacles as assembled smart and shapely in design, so that its industrial applicability is very high.
