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 11):
The method for providing an ophthalmic progressive addition lens as claimed in  claim 8 , according to which one calculates the lens so as to fulfil following requirement of a criterion, LAcuSub60_85(0.1):\n LAcuSub60_85(0.1)\u00b7 ADD p >75 deg 2 \u00b7D , wherein: LAcuSub60_85(0.1) is the angular extent (in deg 2 ) of the zone of the lens where ACU(\u03b1, \u03b2)<0.1 log MAR where \u03b160%\u2265\u03b1\u2265\u03b185%; ACU(\u03b1, \u03b2) is the acuity loss value expressed in log MAR and defined according to following equation: ACU(\u03b1, \u03b2)=\u2212log (AC %(\u03b1, \u03b2)/100); AC %(\u03b1, \u03b2)=100\u221263\u00d7P(\u03b1, \u03b2)\u221244.3\u00d7ASR(\u03b1, \u03b2)+7.2\u00d7P(\u03b1, \u03b2) 2 +19.5\u00d7P(\u03b1, \u03b2)\u00d7ASR(\u03b1, \u03b2)+ASR(\u03b1, \u03b2) 2 ; when P(\u03b1, \u03b2)\u22650; and, AC %(\u03b1, \u03b2)=100\u221244.3\u00d7ASR(\u03b1, \u03b2)+ASR(\u03b1, \u03b2) 2 ; when P(\u03b1, \u03b2)<0; P(\u03b1, \u03b2)=PPO(\u03b1, \u03b2)\u2212PPO(\u03b1, \u03b2_\u03b1_mer); \u03b2_\u03b1_mer is the value of the azimuth angle \u03b2 on the meridian line, ML(\u03b1, \u03b2), at the lowering angle \u03b1.
