| 摘要 | An easy-to-manufacture contact lens exhibiting an excellent axial stability and having a novel ballast mechanism. On the front surface (36) of the contact lens (30), (i) a circular front surface (38) forming an optical part (44) and (ii) annular front surfaces (40, 42) forming peripheral parts (46, 48) are formed with a substantially constant radial dimension around the geometrical central axis (32) of the lens in the front view thereof. Cross-sectional shapes of the front surfaces (40, 42) at the peripheral parts are varied in the circumferential direction and the thickness at the peripheral parts (46, 48) is varied in the circumferential direction, thus shifting the center of gravity G of the contact lens (30) from the geometrical central axis (32) of the lens. | ||||||
