20090122264 | Methods and Apparatuses for Enhancing Peripheral Vision - Methods and apparatuses are disclosed for improving peripheral vision by positioning the peripheral image points at a pre-determined and precise position relative to the retina to achieve optimal performance according to one or more pre-selected criteria parameters for optimal peripheral vision performance. | 05-14-2009 |
20130182216 | TREATING OCULAR REFRACTIVE ERROR - A lens for an eye that includes a zone with a first power profile for images received by the retina on the fovea, a zone with a second power profile for images received by the peripheral retina on the nasal side and a zone with a third power profile for images received by the peripheral retina on the temporal side. The first power profile is selected to provide clear or acceptable vision and the second and third power profiles are selected to affect the peripheral image position. | 07-18-2013 |
20140132914 | MEANS FOR CONTROLLING THE PROGRESSION OF MYOPIA - A contact lens for use in controlling or retarding the progression of myopia in an eye has a central optical zone approximating the normal diameter of the pupil of the eye that gives clear central vision at distance for the wearer. An annular peripheral optical zone that is substantially outside the diameter of the pupil is formed around the central optical zone with greater refractive power than that of the central zone so that oblique rays entering the eye through the peripheral optical zone will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface of the lens is shaped to conform to the cornea of the eye and the front surface of the lens is shaped to provide—in conjunction with the rear surface—the desired optical properties of the central and peripheral optical zones. The front surface is also preferably contoured to form a smooth transition between the junction of the central optical zone and the peripheral optical zone, with or without designed optical properties such as progressive power. | 05-15-2014 |
20140132933 | MYOPIA CONTROL MEANS - Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than −6D central refractive error. In one example, a kit or set of lenses ( | 05-15-2014 |
20150316788 | OPHTHALMIC OPTICAL LENS FOR VISION CORRECTION HAVING ONE OR MORE AREAS OF MORE POSITIVE POWER - The present disclosure is directed to lens, methods of making, designing lens and/or methods using lens in which performance may be improved by providing one or more steps in the central portion of the optical zone and one or more steps in the peripheral portion of the optic zone. In some embodiments, such lens may be useful for correcting refractive error of an eye and/or for controlling eye growth. | 11-05-2015 |

20120320333 | CONTACT LENSES FOR MYOPIC EYES AND METHODS OF TREATING MYOPIA - A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (an add power). In some embodiments the add power is substantially constant across the inner optic zone. In other embodiments the add power is variable across the inner optic zone. While in some embodiments the inner optic zone has a power designed to substantially eliminate lag of accommodation in the eye with myopia, in other embodiments, the add power may be higher. | 12-20-2012 |
20120320334 | CORNEAL REMODELLING CONTACT LENSES AND METHODS OF TREATING REFRACTIVE ERROR USING CORNEAL REMODELLING - Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localised remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localised remodelling. | 12-20-2012 |
