摘要： The invention provides progressive addition lenses in which lens unwanted astigmatism is reduced and channel width through the intermediate and near vision zones is increased as compared to conventional progressive addition lenses. This result is achieved by combining a progressive addition surface with a first dioptric add power with at least one optical element that provides additional dioptric add power to 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： 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.

摘要： A compound ophthalmic lens having improved chromatic aberration is provided which includes a polymerized resin superstrate lens formed on a substrate lens. The chromatic dispersion characteristics of the resin, as well as its refractive index, are matched to the substrate lens to obtain the desired Abbe number, lens power and thickness of the finished lens, and to render the interface between the substrate lens and the superstrate lens substantially invisible. The color dispersion of the substrate lens is compensated for by the superstrate lens which has a relatively low Abbe number and has an opposite power from the substrate lens.
