Glasses, including glasses, adjustable for otimizae a viewing angle of the user during vertical activity of low head.And the system of glasses, adjustable to optimize the optical characteristics of the glasses along a line of vision of the 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 qualities and protetPray for the activities having differing angles of head and primary lines of vision. 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.
