    摘要: There is disclosed a venting system adapted to direct air flow over the inside of an eyeglass lens to minimize a tendency to fog. The venting system may be an integral part of a pair of eyeglasses, or may be incorporated in a separate member, in particular a shielding cassette, adapted to be used with a pair of eyeglasses.
