Abstract: A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.

Abstract: 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.
