Abstract
An eye protecting hood member made of a soft material is joined to lens rims and auxiliary temples of a spectacle frame made of a rigid material, without using any adhesive. The hood member is provided in the form of a fin between an upper side of each rim and the auxiliary temple and between an outer lateral side of each rim and the auxiliary temple for closing a space between the hood member and the face of the wearer. The lens rim is formed in the inner face of each of the upper side and the outer lateral side with at least one narrow groove so shaped as to enlarge toward its bottom. Each of the temples is formed in its inner face with at least one narrow groove so shaped as to enlarge toward its bottom. The soft material forming the hood member is filled in the narrow grooves in the lens rim and the auxiliary temple. Preferably, the narrow groove of the lens rim has a channel communicating with a lens fitting groove, and the auxiliary temple has a bore vertically extending therethrough. The soft material forming the hood member is also filled in the channel and the bore.
