摘要

Glasses, including u00e0culos adjustable to otimizae an angle of visualizau00c7u00e7o vertical of the user during activity of head low, and u00e0culos system adjustable to optimize the characteristics of the u00e0culos u00e0ticas along a line of visu00e7o of user.Are given glasses (10) for the weight of the component without reducing the overall structural integrity of the glasses (10), and to allow the adjustment of the glasses (10) to optimize the optical and protective qualities during the activities having differing angles of the head and the primary lines of sight di Different. The glasses (10) may include a lens (12), a frame (14) and a nose support (18).The frame (14) may have opposite terminals (30), and an upper groove (32) that extends at least partially along the frame (14) and a stem which extends downward in (34).The support of the nose (18) can be a component assembly (42) that extends upward way to connect to the shaft (34) and lens (12) can be retained in cooperation between the frame (14) and the support of the nose (18). Are given sets of pieces of nose and the corresponding lenses, to optimize the lenses for different axes of vision primary in the vertical plane.
