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 1):
An ophthalmic progressive addition lens for a myopic and presbyopic wearer, which has a prescribed far vision mean refractive power equal or less to minus 1 Diopter, or for an emmetropic and presbyopic wearer, which has a prescribed far vision mean refractive power greater than minus 1 Diopter and less than plus 1 Diopter, and a non nil prescribed addition, ADD p , said lens having a far vision reference point, a mean refractive power, PPO(\u03b1, \u03b2), a module of resulting astigmatism, ASR(\u03b1, \u03b2), a meridian line, ML(\u03b1, \u03b2), said (\u03b1, \u03b2) functions being determined in as-worn conditions of the lens by the wearer for gaze directions (\u03b1, \u03b2) joining the center of rotation of the eye, CRE, and the lens, where \u03b1 is a lowering angle in degree and \u03b2 is an azimuth angle in degree, and wherein a lens criterion, A1/A2, fulfils following requirement:\n A 1/ A 2\u22650.50, where: \n A1=\u03b1100%\u2212\u03b185%; \n A2=\u03b1100%\u2212\u03b160%; \n \u03b1100% being the lowering angle corresponding to the minimum positive \u03b1 angle between: \n the lowering angle where 100% of the prescribed addition is perceived by the wearer on the meridian line, \n the lowering angle where the mean refractive power on the meridian line is maximum, PPO max (\u03b1 ML , \u03b2 ML ); \n \u03b185% being the lowering angle where 85% of the prescribed addition is perceived by the wearer on the meridian line; \n \u03b160% being the lowering angle where 60% of the prescribed addition is perceived by the wearer on the meridian line; \n (\u03b1 FV , \u03b2 FV ) is the far-vision gaze direction, FVGD, defined as the vision gaze direction corresponding to the far vision reference point.
