Tilted-wear type contact lens |
摘要 |
A contact lens including a circumferential positioning member that can selectively set up a first stable state where a superficial center of a second power zone is decentered on a symmetrical meridian from a geometrical center of an optical zone and an orthogonal meridian perpendicular to the symmetrical meridian with the lens worn on a right eye is circumferentially tilted by a first angle relative to a vertical line of the eye, and a second stable state where the orthogonal meridian 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, as well as a visible indicator mark for identifying a lens orientation. |
