Patent number: 8789945Abstract: Disclosed is an implementation of new technology for effectively providing a contact lens capable of achieving satisfactory corrective effects even with respect to irregular astigmatism (residual irregular astigmatism) caused by a conical cornea and so forth, which could not be corrected with conventional eye glasses or contact lens, wherein the contact lens is not dependent on being made to order for each wearer but is industrially mass-producible by means of a practical and novel structure. A contact lens for correction of irregular astigmatism is disclosed wherein a positive correction area (27) is provided on one side of a special radial line (30) and a negative correction area (28) is provided on another side while in any of the correction areas (27, 28) a lens power is configured so that an absolute value becomes progressively larger from an outer peripheral edge part towards a central portion.Type: GrantFiled: March 24, 2011Date of Patent: July 29, 2014Assignees: Menicon Co., Ltd., Osaka UniversityInventors: Asaki Suzaki, Yuji Goto, Naoyuki Maeda
