| A method and system for treating Presbyopia and pre-Presbyopia are provided that do not compromise the wearer's intermediate or distance vision. The system is a lens and a lens series, wherein the power profiles of the lenses are tailored to provide an amount of positive ADD power in the near vision zone that is slightly less than that which is normally required for near vision accommodation, while also providing an amount of negative spherical aberration in the peripheral optical zone. The dynamic ocular factors of the wearer's eye work in conjunction with the positive ADD power provided by the central optical zone and with the effective ADD gained from the negative spherical aberration provided by the peripheral optical zone to induce a minimally discernible amount of blur that is tuned to maximize the wearer's depth of focus. | ||||||

| Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than −6D central refractive error. In one example, a kit or set of lenses (50, FIG. 15) can have multiple parts or sub-sets (52, 54) each comprising a compartmented container (56a, 56b) with lenses (58a, 58b) arranged according to increments of central corrective power (59a, 59b). The lenses (58a) of the first part (52) have four steps (60a, 61a, 62a, 64a) of peripheral power or defocus to provide therapeutic effect and, while the lenses (58b) of the second part (54) also have four steps (60b, 61b, 62b, 64b), the level of therapeutic effect is higher. Other examples of sets, kits and stocks, as well as examples of lenses themselves, are disclosed together with methods of use. | ||||||

A contact lens for correction of irregular astigmatism is disclosed wherein a positive correction area (27) is provided on one side of a special radial line (30) and a negative correction area (28) is provided on another side while in any of the correction areas (27, 28) a lens power is configured so that an absolute value becomes progressively larger from an outer peripheral edge part towards a central portion. | ||||||
