摘要： Aspects of the present invention provide an ophthalmic lens comprising at least one regressive and at least one non-regressive rotationally symmetric optical design element. The regressive and non-regressive optical design elements can be combined so as to form a desired optical power profile for the lens while simultaneously exploiting the different relative orientation of the astigmatic vectors of the constituent regressive and non-regressive design elements, thereby resulting in reduced unwanted astigmatism. The regressive and non-regressive rotationally symmetric optical design elements can be positioned on different lens surfaces and in optical communication or can be collapsed onto the same lens surface. The regressive and non-regressive rotationally symmetric optical design elements can each contribute to the total add power of an ophthalmic lens. The regressive and non-regressive rotationally symmetric optical design elements can be combined with any other optical design feature positioned on the same or a different surface of the lens.
