    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: 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 machined on the optical preform at a location based on the reference position on the optical preform.
