Abstract:

An auxiliary frame for detachably mounting in front of a spectacle frame includes a mounting frame and a retention arrangement. The mounting frame supports two shelter lenses for detachably mounting on a spectacle bridge. The retention arrangement includes two guiding members and two urging members. The two guiding members are rearwardly extended from two inner sides of the shelter lenses respectively and defined a guiding distance between the two guiding members which is smaller than the lens distance of the spectacle frame. The two urging members define an urging distance which is larger than the lens distance of the spectacle frame, such that when the guiding members are extended at the two inner sides of the spectacle lens respectively, the two urging members are adapted for applying an urging force against the two inner sides of the spectacle lens respectively.
