An ophthalmic progressive refracting lens for presbyopia in myopia and how to provide such lenses

摘要

An ophthalmic progressive power lens for a myopic and presbyopic wearer and a method of providing such a lens. An average refractive power PPO (α, β), a resultant astigmatism module ASR (α, β), and a visual acuity reduction value ACU (α, β), the (α, β) function Is determined by the wearing state of the lens by the wearer, and satisfies the following requirements: First visual acuity evaluation criteria Criterion 1: Acuity Criterion 1 ≧ 1340D2. deg2 where Acuity Criterion 1 is defined as a combination of PPO (α, β), ASR (α, β), ADDp, and ACU (α, β), and an ophthalmology for myopic and presbyopic wearers Progressive power lens.
