摘要:
1. An ophthalmic lens, soderzhaschayaoptiku having a front surface and a rear surface located on the optical axis, wherein: at least one of the surfaces has a profile characterized by superposition of a base profile and an auxiliary profile, said auxiliary profile comprises a continuous picture of the surface of the deviations from the basic profile .2. The lens of claim 1, wherein the front surface and rear surface are vypuklymi.3. The lens of claim 1, wherein the front surface and rear surface are vognutymi.4. The lens of claim 1, wherein the base profile is generally sfericheskim.5. The lens of claim 1, wherein the base profile is symmetrical about the optical axis of an ophthalmic linzy.6. The lens of claim 1, wherein the base profile is generally asfericheskim.7. The lens of claim 1, wherein the auxiliary profile is symmetrical about the optical axis of an ophthalmic linzy.8. The lens of claim 1, wherein the auxiliary profile is a sinusoidal profil.9. The lens of claim 8, wherein the profile of the surface having the auxiliary profile is defined by the following relation: gdea denotes the amplitude of the sinusoidal curve and the diffraction efficiency at different foci ab represents the frequency and the added optical silu.10. The lens of claim 8, wherein the sinusoidal profile of the amplitude modulated with a cosine function, acting to shift the light into the selected diffraction order, wherein the amplitude modulated surface profile having said auxiliary profile is defined by the following relation: gdea denotes the amplitude of the sinusoidal curve and the diffraction efficiency in various Fok1. Офтальмическая линза, содержащаяоптику, имеющую переднюю поверхность и заднюю поверхность, расположенные по оптической оси, где:по меньшей мере, одна из поверхностей имеет профиль, характеризуемый наложением базового профиля и вспомогательного профиля, причем вспомогательный профиль включает непрерывную картину отклонений поверхности от базового профиля.2.
