Ophthalmic progressive power lens for presbyopic wearers with myopia or normal vision and a method for providing such a lens

摘要

An ophthalmic progressive power lens for presbyopic wearers with prescription distance vision mean power and non-zero prescription addition ADD _P , said lens being a far vision reference point and mean power PPO (α, β) And the resulting astigmatism module ASR (α, β) and meridian ML (α, β), wherein the (α, β) function is the wearing state of the lens by the wearer, Determined with respect to the line-of-sight direction (α, β) connecting the eye rotation point CRE and the lens, a is a descending angle in degrees, β is an azimuth angle in degrees, and the lens evaluation criterion A1 / A2 satisfies the following requirements: A1 / A2 ≧ 0.50, where A1 = α100% −α85%, A2 = α100% −α60%.
