ABSTRACT:
The sunglasses structure comprises a front piece, an arm hinged to each end of the front piece, and a one-piece lens supported by the front piece. A milling is formed in the lens which is substantially V-shaped, with inwardly protruding coupling elements. A V-shaped elastically deformable bridge is insertable into the milling. The bridge has a perimetral groove for accommodating a perimetral portion of the milling and a plurality of seats accommodating the coupling elements, which snap into engagement with the seats upon inserting bridge into the milling. Air vents are provided at a lateral portion of the lens for preventing misting.
