Abstract
Swimming goggles comprising a rigid frame (2) for supporting a pair of glass-shaped transparent members (1), each formed by a flat lens (1a) and a flanged bush (1b) for the connection to the frame, the bush being made of a mouldable thermoplastic material. The flat lenses are made of a plastic material different from that of the bushes and having a softening temperature higher than that of the material of the bushes and no-mist and/or no-scratch properties. The lenses are perimetrically fixed to the bushes within grooves (6) formed on the respective bushes.
