    摘要: The invention relates to a method of selection of an ophthalmic lens suitable for correcting at least an optical impairment of an eye of a wearer who observes a screen. According to the invention the method comprises the steps of: determining at least a characteristic of posture of the wearer observing said screen, determining a dioptric power value associated to said vision zone allowing the wearer when wearing the ophthalmic lens to have an easier reading of said screen, determining at least one characteristic of filtering means to adjust the light exposure of the wearer to said screen, and determining the vision zone based on dioptric power value, characteristic of posture of the wearer and characteristic of filtering means so that the vision comfort of the wearer is optimized when wearing the ophthalmic lens while observing a screen.
