Eyeglass assembly having a coupling unit for coupling primary and auxiliary eyeglasses

摘要

An auxiliary eyeglass is mounted frontwardly on a primary eyeglass having a primary bridge interconnecting two primary lenses. The auxiliary eyeglass includes two auxiliary lenses disposed frontwardly of and aligned with the primary lenses respectively. A coupling unit includes a hook member hooked on the primary bridge, a first threaded unit extending in a transverse direction relative to the primary bridge and the hook member and selectively connected to one of the hook member and the auxiliary lenses, and a mounting unit selectively connected to the other one of the hook member and the auxiliary lenses with the first threaded unit extending through the mounting unit. A second threaded unit is mounted threadedly on the first threaded unit and adjustably abuts against two opposite sides of the mounting unit so as to permit adjustment and positioning of the auxiliary lenses relative to the primary lenses.
