Abstract
Providing to an eye a customizable ophthalmic lens comprising a transparent set of electroactive cells () juxtaposed to a lens surface for providing an optical phase-shift distribution function. The method includes providing () a reference phase-shift distribution function adapted to provide a given dioptric function DF(α, β); determining () the actual gaze direction (α, β); choosing () a reference gaze direction (α, β); calculating () an actual point Pat the intersection between the actual gaze direction and the transparent set of electroactive cells, and a reference point Pat the intersection between the reference gaze direction and the transparent set of electroactive cells; calculating () a modified phase-shift distribution function by shifting the reference phase-shift distribution function according to a vector {right arrow over (PP)}; and activating () the electroactive cells according to the modified phase-shift distribution function.
