Hybrid progressive electro-active ophthalmic lens

摘要

Disclosed is an ophthalmic hybrid lens comprising a multi-focal progressive lens having two or more fixed focal powers, the multi-focal progressive lens providing correction for distance vision and add power for correction of near vision, the add power being lower than that required for fully corrected near vision; and an electro-active lens element for providing variable focal power. The hybrid lens is operable such that it provides a final add power for correction of near vision that is the total additive power of the add power for correction of near vision provided by the multi-focal progressive lens and the additional required add power generated by the electro-active lens.
