Abstract
A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following steps: providing a value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation, according to both visual and non visual frames of reference; calculating a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism and/or optical power repartition according to gaze direction based on the value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation.
