1. An ophthalmic lens adapted to be worn by a wearer, wherein the lens is designed as a function of the wearer's handedness,
wherein said ophthalmic lens has respective nasal and temporal half-widths of a near-vision zone with respect to a proximate-vision gaze direction, of an intermediate-vision zone with respect to a meridian line, and of a distant-vision zone with respect to a distant-vision gaze direction, wherein said lens is asymmetric in that: the nasal/temporal half-widths of one or more of the following:
the near-vision zone with respect to a proximate-vision gaze direction,the intermediate-vision zone with respect to the meridian line,the distant-vision zone with respect to a distant-vision gaze direction, are asymmetric as a function of the wearers handedness, and/or at least one optical parameter between the nasal part and the temporal part of the lens is asymmetric as a function of the wearers handedness, wherein said optical parameter is selected from
any one of central vision optical criteria selected from the group comprising: power in central vision, astigmatism in central vision, high order aberration in central vision, acuity in central vision, prismatic deviation in central vision, ocular deviation, object visual field in central vision, image visual field in central vision, magnification in central vision;any one of peripheral vision optical criteria selected from the group comprising: power in peripheral vision, astigmatism in peripheral vision, high order aberration in peripheral vision, pupil field ray deviation, object visual field in peripheral vision, image visual field in peripheral vision, prismatic deviation in peripheral vision, magnification in peripheral vision;any one of global optical criteria selected from the group comprising: magnification of the eye, temple shift,any one of surface criteria selected from the group comprising: front or back mean curvature, front or back minimum curvature, front or back maximum curvature, front or back cylinder axis, front or back cylinder, front or back mean sphere, front or back maximum sphere, front or back minimum sphere, and/orthe maximal value (respectively, minimal value, peak-to-valley value, maximal gradient value, minimal gradient value, maximal slope value, minimal slope value, average value) of any one of the preceding criteria, in one or more useful zones of the lens, including zones for near-vision, distant-vision, and intermediate-vision, wherein the lens is asymmetric in that at least one optical parameter (π) between the nasal (N) part and the temporal (T) part of the lens is asymmetric as a function of the wearer's handedness, and wherein:
ABS[(πT−πN)/avg(πT;πN)]>0.15 wherein:
ABS is absolute value,avg denotes the average value. |
