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.
A method of determining an ophthalmic lens suitable for improving vision of a wearer when observing a screen, the ophthalmic lens comprising a far vision zone, a near vision zone, and a stabilized ultra near vision zone, the stabilized ultra near vision zone being provided with filtering means, being distinct from the far vision zone and from the near vision zone, and corresponding to a lowering gaze angle of the wearer observing the screen greater than 21°, and to a zone through which the wearer looks at said screen at a distance small than 40 centimeters, wherein the method comprises the steps of:
An ophthalmic lens suitable for improving vision of a wearer when observing a screen wherein the ophthalmic lens comprises a far vision zone, a near vision zone, and a stabilized ultra near vision zone, the stabilized ultra near vision zone being provided with filtering means, being distinct from the far vision zone and from the near vision zone, and corresponding to a lower gaze angle of the wearer observing the screen greater than 21°, and to a zone through which the wearer looks at said screen at a distance smaller than 40 centimeters, said stabilized ultra near vision zone being designed based on:
A method of providing a wearer of an ophthalmic lens with a rating of said ophthalmic lens, wherein the ophthalmic lens comprises a far vision zone, a near vision zone, and a stabilized ultra near vision zone, the stabilized ultra near vision zone being provided with filtering means, being distinct from the far vision zone and from the near vision zone, and corresponding to a lowering gaze angle of the wearer observing the screen greater than 21°, and to a zone through which the wearer looks at said screen at a distance smaller than 40 centimeters, wherein the method comprises the steps of:
