L'invention concerne une monture de lunettes dépourvue de charnières (12), conçue de telle sorte que la monture de lunettes tout entière imprime une force centrale sur la partie postérieure des branches (16, 18), accroissant ainsi la force de rétention exercée entre les lunettes et la tête. Dans un mode de réalisation comportant des aérations, chaque verre d'une monture à deux verres (66) est muni de plusieurs ouvertures (86) situées à la jonction du vere (64) et de la monture qui l'encercle (70). La monture en une seule pièce et la monture conventionnelle à charnières peuvent également comporter des ouvertures (80, 82) permettant à l'air de circuler.
