<p>The invention proposes a method for providing to an eye a customizable ophthalmic lens comprising a transparent set of electroactive cells (24) juxtaposed to a surface of the said lens, said set of cells being activable and suitable for providing an optical phase-shift distribution function, the said method comprising the steps of: providing (402) a reference phase-shift distribution function adapted to provide a given dioptric function DF(alpha, beta); determining (404) the actual gaze direction (alphaa, betaa) of the eye; - choosing (406) a reference gaze direction (alphaR, betaR); calculating (408) an actual point Pa and a reference point PR, said actual point Pa being the intersection between the actual gaze direction of the eye and the transparent set of electroactive cells and said reference point PR being the intersection between the reference gaze direction of the eye 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 ⃗ PRPa; and activating (412) the electroactive cells according to the said modified phase- shift distribution function so as to provide a customized ophthalmic lens to the eye.</p> |
