Patent ID: 8182087

Claim:
A method for optimizing and producing a spectacle lens, comprising a calculation or optimization step of at least one of the surfaces of the spectacle lens in consideration of an anisometropia D of the eyes of a spectacle wearer, wherein the calculation or optimization step is performed in such a way that a target function F is minimized: min ⁢ ⁢ F = ∑ i ⁢ gP i ⁡ ( ( PR ⁡ ( i ) - PL ⁡ ( i ) ) - P set ⁡ ( i ) ) 2 ⁢ : PR(i) refers to a prismatic power at the i-th evaluation point of the spectacle lens; PL(i) refers to a prismatic reference power at the i-th evaluation point of the spectacle lens; P set (i) refers to a target value of the difference ΔP of the prismatic power PR(i) and the prismatic reference power PL(i) at the i-th evaluation point of the spectacle lens; and gP i refers to a weighting of the prismatic power at the i-th evaluation point of the spectacle lens; and the prismatic reference power PL(i) is the prismatic power in a visual point of a second spectacle lens corresponding to the i-th evaluation point, and the spectacle lens and the second spectacle lens form a spectacle lens pair for joint use in a pair of spectacles for correcting the anisometropia of the spectacle wearer.
