SOFT CONTACT LENS AND METHOD FOR PREVENTING ADSORPTION OF SOFT CONTACT LENS ONTO CORNEA

摘要

Provided is a soft contact lens including a silicone compound as a constituent component that is capable of suppressing attachment onto a cornea during wearing and has excellent fitting properties and a method for suppressing attachment of the soft lens onto the cornea. The contact lens 10 is a soft contact lens having no water content or low water content and includes a circular central part 1 positioned at the center, an intermediate part 2 positioned at the outer peripheral side of the central part 1 and forming an annular shape having a center coaxial with the central part 1, and an outer edge part 3 positioned at the outer peripheral side of the intermediate part 2 and forming an annular shape having a center coaxial with the central part 1, in which respective radii of curvature of the central part 1, the intermediate part 2, and the outer edge part 3 of the contact lens 10 are different from each other, and a sagittal depth of the contact lens 10 is within a range of a sagittal depth in the case where the entire soft contact lens is formed in a range of an radius of curvature ±0.2 mm of the outer edge part 3.
