    摘要： A contact lens including a circumferential positioning member (40, 42, 44, 46) that can selectively set up a first stable state where a superficial center (30) of a second power zone (24) is decentered on a symmetrical meridian (22) from a geometrical center (20) of an optical zone (14) and an orthogonal meridian (34) perpendicular to the symmetrical meridian (22) with the lens worn on a right eye is circumferentially tilted by a first angle relative to a vertical line (50) of the eye, and a second stable state where the orthogonal meridian (34) under condition in which the lens is worn on a left eye with the right eye wearing state inverted upside down is circumferentially tilted by a second angle on the opposite side of the first angle relative to the vertical line (50), as well as a visible indicator mark (48) for identifying a lens orientation.
