AN OPHTHALMIC LENS

摘要

An ophthalmic lens comprising a diffractive part and a method for designing such a lens. According to the invention the ophthalmic lens further comprise s a refractive part comprising at least one surface, which is configured to compensate a passing wavefront at least partly for at least one type of monochromatic aberration introduced by at least one of the optical parts of the eye. Said diffractive part is capable of compensating a passing wavefron t at least partly for chromatic aberration introduced by at least one of the optical parts of the eye. Furthermore said refractive and diffractive parts together contribute to a required power of the lens.
