Abstract
An array of progressive ophthalmic lens elements is disclosed. The progressive ophthalmic elements contained in the array having substantially the same addition power and substantially the same optical prescription for distance vision. Each of the progressive ophthalmic lens elements has a progressive lens design characterized by a set of 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 having a refracting power varying from that of the distance zone to that of the near zone. The progressive ophthalmic lens elements provide, for a range of values or categories of at least two lifestyle and/or biometric parameters 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.
