发明名称 Methods of designing progressive addition lenses
摘要 Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens that take the patient's complete measured wavefront into account. Specific embodiments also consider one or more additional factors such as vertex distance, intermediate power, add power, 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 effect of the patient's measured wavefront and/or the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and/or the lens wavefront on a grid. In an exemplary 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 that the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid are taken into account. The progressive addition lens can be utilized for distance, intermediate and reading use wherein the power progression is non-linear in any number or all of the near, intermediate, and far zones.
