A method for determining a progressive ophthalmic lens, comprising determining first, second and third intermediate values of regression as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the rear surface of the lens less or equal to, respectively, first, second and third predetermined values; and determining a value of regression (d) for the front surface as the maximum value among the first, second and third intermediate values of regression.
