Abstract:
In one aspect, the present invention provides a two-element ophthalmic lens in which a lateral shift of the elements relative to one another can cause a variation not only in a spherical power provided by the lens but also in spherical aberration exhibited by that lens. In some implementations, the thickness profiles of the two elements are designed such that the variation in spherical aberration is positively correlated with that of the spherical power of the lens.
