Abstract: A decentered type contact lens including: an optical zone provided in a center part of the contact lens; a peripheral zone provided on an outer circumference of the optical zone; an optical center of the optical zone being set to deviate from a lens geometric center; and a circumferential direction alignment mechanism for setting a lens circumferential direction position in a worn state, the contact lens being characterized in that: a center-of-gravity deviation in relation to the lens geometric center is set for the peripheral zone, and a center-of-gravity position shift accompanying deviation of the optical center of the optical zone in relation to the lens geometric center is corrected by offset using the center-of-gravity deviation of the peripheral zone.

Abstract: To provide a contact lens with novel structure that is able to achieve both stability of the lens circumferential position in the worn state and improved wearing comfort at a high level. A first thick part and a second thick part are provided on a peripheral zone at both left and right sides such that each center-of-gravity position of both the first thick part and the second thick part is positioned below a horizontal diametrical line. A third thick part is provided on the peripheral zone below an optical zone. An upper thin part and a lower thin part are provided respectively at an upper peripheral zone positioned above the optical zone and a lower peripheral zone positioned below the optical zone and at an outer circumference side of the third thick part.

Abstract: A presbyopia contact lens set especially for a user who has worn spherical contact lenses, a designing method for a presbyopia contact lens, and a manufacturing method for a presbyopia contact lens that uses such design method. The presbyopia contact lens set configured by combining a plurality of types of presbyopia contact lens having different specifications lens powers, includes the plurality of types of presbyopia contact lenses in which the radial lens power profile in a near-use region and that in a far-use region are defined using mutually different functions, the function for defining the radial lens power profile in the far-use region is set in accordance with a specifications lens power, and the radial lens power rate-of-change in the far-use region is made larger for lenses having a small specifications lens power than for lenses having a large specifications lens power.
