摘要

An ophthalmic progressive addition lens for a myopic and presbyopic wearer; method for providing such a lens. An ophthalmic progressive addition lens for a myopic and presbyopic wearer having a mean refractive power, PPO(α, β), a module of resulting astigmatism, ASR(α, β), an acuity loss value ACU(α, β), where said (α, β) functions are determined in as-worn conditions of the lens by the wearer, and a first acuity criterion, AcuityCriterion1 which fulfils following requirement: AcuityCriterion1 ≥ 1340 D².deg², and where: AcuityCriterion1 is defined as a combination of PPO(α, β), ASR(α, β), ADD
