Disclosed is a method for determining a specific near vision power of an ophthalmic lens to be provided to a wearer having an ophthalmic prescription, the specific near vision power being for near distance vision, the method including: an ophthalmic lens providing step during which at least an ophthalmic lens having a near distance vision zone including a mean power adapted for near distance vision is provided to the wearer; a near vision task speed determining step during which the processing speed of a near vision task by the wearer when wearing the provided ophthalmic lens is determined; wherein the ophthalmic lens providing step and the near vision task speed determining step are repeated with ophthalmic lenses having different mean power, so as to determine a specific near vision power corresponding to the mean power providing an improved near vision task processing speed.
