A goggle (20) comprising a lens (21b), a frame (24), a lens-retention mechanism and an adjustment mechanism (28) wherein the lenses can be selectively moved relative to the frame to at least two different positions defining substantially different levels of air flow between the lenses and frame while maintaining the lenses in front of a user's eyes, and retained at each position. In certain embodiments, one position is defined by substantially all of the lens periphery contacting the frame to substantially form a seal. The adjustment and lens-retention mechanisms may be the same mechanism.

La présente invention se rapporte à des lunettes qui comprennent un verre, une monture, un mécanisme de retenue du verre et un mécanisme d'ajustement qui permettent de déplacer sélectivement les verres par rapport à la monture dans au moins deux positions différentes définissant des niveaux sensiblement différents de circulation d'air entre les verres et la monture tout en maintenant les verres devant les yeux d'un utilisateur, lesdits verres étant retenus dans chaque position. Dans certaines formes de réalisation, une position est définie par sensiblement tout le pourtour de la lentille en contact avec la monture pour former pratiquement un joint. Les mécanismes d'ajustement et de retenue du verre peuvent se présenter sous forme d'un seul et unique mécanisme.
