<p>This contact lens, for which QOV is improved by providing an optical center that is shifted from the geometrical center of the lens, has a novel structure such that the contact lens can be manufactured and handled without distinguishing between a lens for the left eye and for the right eye and also such that a mark or the like showing the shift direction for the optical center is unnecessary. A contact lens (10) is provided with first strength areas (20) and a second strength area (22) in an optical area (14). A pair of first strength areas (20) is provided linearly symmetrical with respect to a radial line of symmetry (24) which is a line in the radial direction of the lens, and also a second strength area (22) is provided on the outer peripheral sides of that pair of first strength areas (20). The optical area (14) has a linear symmetrical shape with respect to the radial line of symmetry (24). Furthermore, a circumferential direction positioning means (36) that imparts a stable position in the circumferential direction of the lens such that the radial line of symmetry (24) extends in the vertical direction of the wearing eye in a worn state and either of the pair of first strength areas (20) is aligned with the center of the pupil (32) of the wearing eye.</p> |
