Abstract
Provided is a contact lens having a novel structure with a high level of practicality which is easy to manufacture and apply to users, and can improve quality of vision (QOV). In an optical part of a contact lens, a spherical aberration of a size corresponding to a coma aberration of a user's naked eye, and of a size for which a spherical aberration of the user's naked eye will not be offset and will be made to remain is set as a corrective optical characteristic for a residual irregular astigmatism of the user's naked eye. A high-order aberration of the optical part is set rotationally symmetric around an optical axis.
