Abstract

739,493. Spectacles. WILLESDEN OPTICAL WORKS, Ltd. April 23, 1954 [April 23, 1953], No. 11246/53. Class 97 (1). In spectacles having lenses of the kind used by myopic people and with thick edges, each lens is held in an eye rim which at least over the top half of the lens has a tongue entering a groove in the edge of the lens. As shown in Fig. 3 the frame may comprise a plastic member 6 extending over only the top half of the lens 4 which is held in place by a cord engaging the lower periphery of the lens as claimed in Specification 533,161. The member 6 has a tongue 7 engaging a correspondingly shaped groove 5 in the edge of the lens. Alternatively the lens may be grooved around its entire periphery to engage a tongue formed on a plastic rim which is split at diametrically opposite points to allow insertion of the lens.
