Abstract:
An ophthalmic progressive addition lens for a myopic or emmetropic presbyopic wearer which has a prescribed far vision mean refractive power and 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, A1/A2, fulfils: A1/A2≥0.50, wherein: A1=α100%−α85%; A2=α100%−α60%.

Claim (Index 7):
An ophthalmic progressive addition lens as claimed in  claim 1 , according to which said lens comprises two main surfaces facing each other wherein said two main surfaces are complex surfaces, as for example two progressive surfaces or two degressive surfaces or a progressive surface and a degressive surface.
