<p>This invention aims at improving the soft contact lens wearing condition, the productivity thereof and the optical effect thereof. In a soft contact lens consisting of an inner surface (10), an outer surface (12) and an inner and outer surface-connecting surface (14), the inner surface (10) is composed of a central portion (16) of an elliptic surface portion having an eccentricity in the range of 0.2-0.7 and an apex radius of curvature of 5.00-10.00 mm, an intermediate portion (18) of an elliptic surface portion positioned around the central portion (16), having an eccentricity in the range of 0.2-0.7 and different from the central portion (16) in at least one of the eccentricity and apex radius of curvature, and a peripheral portion (20) positioned around the intermediate portion (18) and separating gradually away from a cornea as the peripheral portion is away from the intermediate portion in the radially outward direction, so as to gradually increase the distance between the peripheral portion and the cornea, these three portions being continuously connected. <IMAGE></p> |
