20120327363 | LENS SYSTEMS FOR PRESBYOPIA - A family of ophthalmic lenses for correcting presbyopia meets constraints for distance vision, near vision, and disparity and may be designed according to a process that incorporates a merit function accounting for binocular visual performance. | 12-27-2012 |
20130258277 | METHOD AND APPARATUS FOR A VARIABLE POWER OPHTHALMIC LENS - This invention discloses methods and apparatus for providing an ophthalmic lens with diffractive/refractive variable optic structures. An energy source is capable of powering the variable optic included within the ophthalmic lens as it may be predetermined. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel. | 10-03-2013 |
20140211147 | ASYMMETRIC LENS DESIGN AND METHOD FOR PREVENTING AND/OR SLOWING MYOPIA PROGRESSION - Contact lenses incorporating asymmetric radial power profiles that increase the radial dioptric power from the center to the margin of the optical zone of the lenses may be utilized to prevent and/or slow myopia progression. The power profiles vary along different meridians. | 07-31-2014 |
20140268034 | PRESBYOPIA LENS WITH PUPIL SIZE CORRECTION BASED ON LEVEL OF REFRACTIVE ERROR - Ophthalmic lenses for the treatment of presbyopia may be improved to enhance the visual experience of the patient. By adjusting the optical design of presbyopic lenses to account for changes in pupil size due to the degree of myopia or hyperopia, an enhanced visual experience may be achieved independent of the level of ametropia. | 09-18-2014 |
