摘要：
Providing to an eye a customizable ophthalmic lens comprising a transparent set of electroactive cells (24) juxtaposed to a lens surface for providing an optical phase-shift distribution function. The method includes providing (402) a reference phase-shift distribution function adapted to provide a given dioptric function DF(α, β)； determining (404) the actual gaze direction (αa, βa)； choosing (406) a reference gaze direction (αR, βR)； calculating (408) an actual point Pa at the intersection between the actual gaze direction and the transparent set of electroactive cells, and a reference point PR at the intersection between the reference gaze direction and the transparent set of electroactive cells； calculating (410) a modified phase-shift distribution function by shifting the reference phase-shift distribution function according to a vector {right arrow over (PRPa)}； and activating (412) the electroactive cells according to the modified phase-shift distribution function.
