    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。

    摘要： A progressive optic has an optical preform wherein the radius of curvature of the surface is altered by forming discrete spherical portions across the surface. A thin intermediate layer, having a different refractive index from the optical preform, is then cast over the formed optical preform surface. The optical preform having the thin intermediate layer is then cast with a resin superstrate layer which restores the curve of the optic. Each spherical section, defined by the spherical portions and corresponding portions of the outer surface of the superstrate layer, alters the spherical power of the adjacent spherical section by about 0.03 D to 0.05 D.

    摘要： A method for providing a contact lens for a patient. According to this method, an optical preform is selected, and a resting position of the optical preform on the patient's eye is determined. An optical feature is also located on a patient's eye. Then, a reference position is located on the surface of the optical preform coincident with the optical feature on the patients eye, when the optical preform is in the resting position. Finally, the optical modification is provided on the optical preform at a location based on the reference position on the optical preform, either by machining the preform itself or by machining a mold that is subsequently used to form the lens.
