Abstract:
1. An eyeglass assembly which comprises a lens and a frame member, in which (a) the lens has a recess formed in it which has a generally constant cross-section when viewed from one end along at least part of its length, defined by a pair of opposed arms with reentrant portions at their ends which define a longitudinal opening between them extending along at least part of the length of the recess, and which has an opening at one end, and (b) the frame member bears a head portion, and in which the recess and the head portion are configured so that the head portion can be fitted into the recess by sliding it through the opening at the said end of the recess, and so that the head portion is prevented by the reentrant portions of the arms from being withdrawn from the recess through the longitudinal opening, wherein the eyeglass assembly includes a band which can be fitted around the head portion and the said opposed arms so as to close the opening at the end of the recess, and to prevent the head portion from being withdrawn from the recess.
