Zusammenfassung:PURPOSE:To prevent always the fatigue of user's eyes, by constituting a glasses frame so that pad pieces are automatically operated only with the operation of temples and making it possible to not only move vertically lenses but also change the angle of inclination of lenses with an easy operation. CONSTITUTION:When temples 14 are extended straight and pad pieces 9 are placed above, lens parts 4 for the far distance are placed in approximate centers of user's eyes, and user's eyes are orthogonal to lenses approximately. When the user inclines a main body A around screws 16 forward to temples 14 for the purpose of seeing the near distance, tips of rotating materials 12 are turned upward to supporting materials 13. Therefore, linear bodies 10 are pressed upward and are moved in tubes 11, and inside ends of bodies 10 press sliding bars 7 downward, and pad pieces 9 are pressed downward. When the user wears the glasses in this state, lens parts 5 for the near distance are placed in approximate centers of user's eyes, and user's eyes are orthogonal to lens faces approximately. Thus, the fatigue of user's eyes is prevented with an easy operation of the glasses frame.
