Abstract:
An ophthalmic progressive addition lens for a presbyopic wearer which has a prescribed far vision mean refractive power a non nil prescribed addition, ADD p , the lens having a far vision reference point, a mean refractive power, PPO(α, β), a module of resulting astigmatism, ASR(α, β), a meridian line, ML(α, β), the (α, β) functions being determined in as-worn conditions of the lens by the wearer for gaze directions (α, β) joining the center of rotation of the eye, CRE, and the lens, wherein α is a lowering angle in degree and β is an azimuth angle in degree, and wherein a lens criterion, CRIT, fulfils following requirement: 0.38≤CRIT≤4.50, where: CRIT=NumeratorCRIT/DenominatorCRIT, NumeratorCRIT=(A1/A2)+(PPO(α FV , β FV )/(100·ADD p )); A1=α100%−α85%; A2=α100%−α60%; DenominatorCRIT=[(PeaksMean/ADD p )±(PPO(α FV ,β FV )/(8·ADD p ))] 3 .

Claim (Index 2):
An ophthalmic progressive addition lens as claimed in  claim 1 , according to which CRIT\u22650.39 and CRIT\u22641.50.
