摘要： An ophthalmic progressive addition lens for a presbyopic wearer which has a prescribed far vision mean refractive power a non nil prescribed addition, ADDp, 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 α lens criterion, CRIT, fulfils following requirement: 0.38≤CRIT≤4.50, where: CRIT=NumeratorCRIT/DenominatorCRIT, NumeratorCRIT=(A1/A2)+(PPO(αFV, βFV)/(100·ADDp)); A1=α100%−α85%; A2=α100%−α60%; DenominatorCRIT=[(PeaksMean/ADDp)+(PPO(αFV,βFV)/(8·ADDp))]3.

摘要： A method for determining an optical system of a personalized progressive lens for a given wearer including: a) providing a mean direction of gaze determined for the wearer in a reference frame tied to the head of the wearer; b) determining a target value for at least one optical design parameter as a function of the mean direction of gaze determined in a); c) calculating the optical system of the progressive lens by an optical optimization procedure on the basis of target values, wherein the target value of each optical design parameter as a function of the mean direction of gaze determined in b) is a target value.

摘要： 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, ADDp, 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%.
