Abstract
A method is provided for determining an ophthalmic lens configured to correct an abnormal refraction of an eye of a wearer and including at least three optical elements disposed on a surface of the ophthalmic lens to suppress or reduce a progression of the abnormal refraction of the eye, the method including providing prescription data configured to correct the abnormal refraction; providing at least one abnormal refraction parameter relating to the abnormal refraction; providing at least one sensitivity parameter representing a variation of sensitivity of the wearer as a function of at least one parameter of the optical elements; determining a value of the at least one parameter of the optical elements configured for the wearer based on the abnormal refraction parameter and the sensitivity parameter; and determining the ophthalmic lens based at least on the provided prescription data and the value of the parameter of the optical elements.
