Patent ID: 8210679

Claim:
An array of progressive ophthalmic lens elements having substantially the same addition power and substantially the same optical prescription for distance vision, each of the progressive ophthalmic lens elements having a progressive lens design characterised by a set of lens design parameters defining: a distance zone providing a refracting power for distance vision; a near zone providing a refracting power for near vision; and a corridor connecting the distance and near zones, the corridor having a refracting power varying from that of the distance zone to that of the near zone; wherein the progressive ophthalmic lens elements provide, for a range of values or categories of at least one lifestyle parameter and at least one biometric parameter of lens wearers, different progressive lens designs in which at least two of the lens design parameters each have a respective value or characteristic attributable to, or associated with, a particular value or category of a respective one of the lifestyle and/or biometric parameters.
