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.

tructure de lunettes de soleil comportant une pièce avant, un bras articulé de chaque côté de cette pièce, et une lentille monobloc soutenue par la pièce avant. Une rainure est pratiquée dans la lentille qui est essentiellement en forme de V et comporte des éléments de couplage qui ressortent vers l'intérieur. Un pont élastique déformable en forme de V est inséré dans la rainure. Le pont comporte un sillon périphérique logeant une partie périphérique de la rainure, ainsi que plusieurs assises logeant les éléments de couplage, qui s'y insèrent avec une pression de manière à fixer le pont dans la rainure. Des trous d'aération sont pratiqués sur la partie latérale de la lentille pour prévenir l'embuage.
