Patent number: 8992013Abstract: Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens taking into account the patient's complete measured wavefront. Specific embodiments can also take into account one or more additional factors such as vertex distance, segmental fitting height, pantoscopic tilt, and use conditions. The lens wavefront can be achieved by optimizing a corrected wavefront, where the corrected wavefront is the combined effect of the patient's measured wavefront and the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and the lens wavefront on a grid. In an embodiment, the grid can lie in a plane. During the optimization, a subset of the grid can be used for the representation of the measured wavefront at a point on the grid so as to take into account the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid.Type: GrantFiled: April 30, 2009Date of Patent: March 31, 2015Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Keith Dillon, Jeffrey S.

Publication number: 20140176909Abstract: An inexpensive, easy-to-use self-refracting device which adjusts to continuously variable prescription corrections for a patient. In preferred embodiments specially designed gear arrangements, controlled by control knobs, moves one lens relative to the other or both lenses relative to each other in directions perpendicular to the viewing direction. The patient turns the device's knobs until vision is clearest. Once the patient adjusted the device for best vision, the patient's prescription can be read off various scales on the device. The diopter meter, therefore, can be used to easily and quickly screen for refractive error problems by allowing patients to self-adjust power and, if refractive error is present, see for themselves how much better they could see with corrective glasses.Type: ApplicationFiled: December 20, 2012Publication date: June 26, 2014Inventors: Brett Spivey, Andreas W.
