    摘要： 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.

    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.

    摘要： Aspects of the present invention provide progressive addition lenses (PALs) and techniques for designing PALs that result in improved visual performance for the wearer. PALs of the present invention can have vision zones with widths that are more in line with the actual or functional sizes used by wearers. PALs of the present invention can also introduce controlled amounts of unwanted astigmatism into one or more vision zones. By allowing vision zones to include manageable levels of astigmatism, the resulting PAL can avoid the harsh build-up of astigmatism typically found in conventional PALs at the periphery of the channel and viewing zones. Further, PALs of the present invention can be designed using a merit function to achieve an optimized iterative design that accounts for astigmatism vector orientation and not simply astigmatism magnitude as is the case with conventional PAL design.

    摘要： Aspects of the present invention provide a lens comprising a non-rotationally symmetric aspheric optical element, surface or feature and a rotationally symmetric aspheric optical element, surface or feature. The non-rotationally symmetric aspheric optical feature can be a progressive power region. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can be in optical communication when located on different surfaces of a lens or can be collapsed to occupy a single surface of a lens. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can each contribute to the add power of a lens. Distortion (e.g., astigmatism) of a lens of the present invention can be reduced (e.g., globally and/or locally) by optically combing the non-rotationally symmetric aspheric optical feature with the rotationally symmetric aspheric optical feature. Accordingly, the effective or useable vision zones of a lens of the present invention can be increased.

    摘要翻译： 本发明的方面提供一种包括非旋转对称非球面光学元件，表面或特征以及旋转对称的非球面光学元件，表面或特征的透镜。 非旋转对称非球面光学特征可以是渐进光焦度区域。 当位于透镜的不同表面上时，非旋转对称非球面光学特征和旋转对称非球面光学特征可以是光学通信的，或者可以折叠以占据透镜的单个表面。 非旋转对称的非球面光学特征和旋转对称的非球面光学特征可以各自有助于透镜的附加功率。 通过将非旋转对称非球面光学特征与旋转对称的非球面光学特征光学地组合，可以减小（例如，全局和/或局部地）本发明的透镜的变形（例如散光）。 因此，可以提高本发明的透镜的有效或可用的视野区域。
