摘要
The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens further improves upon an earlier method which utilizes and combines non-circularity and thickness differential aspects which results in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently. This further improvement of stiffness profile is achieved by optimizing and selectively addressing thickness differential both diametrically and circumferentially in a non-round lens design.
