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.

Method of designing progressive addition lenses

An eye simulation system for testing wavefront sensor systems, the eye stimulation system comprising a housing having a chamber with an opening for allowing light to enter said chamber, a fluid located in the chamber, said fluid having a known index of refraction, a lens positioned relative to said housing such that light entering the opening of the chamber passes through said lens, and a rotatable imaging surface positioned in said chamber such that light passing through said lens propagates through said fluid and is incident on said rotatable imaging surface.

Ophthalmic diagnostic instrument

A binocular wavefront measurement system for performing wavefront analysis on the eyes of a patient, the system comprising an optics system for providing an image to a first eye along a first optical path and an image to a second eye along a second optical path and a sensor system, said sensor system configurable in a first mode for performing a wavefront measurement of a first eye through a portion of the first optical path and configurable in a second mode for performing a wavefront measurement of a second eye through a portion of the second optical path.

Diagnostic instruments, systems and methods for performing measurements on eyes are disclosed. In one embodiment of the instrument, a left ocular is disposed in a portion of a left visual path for the left eye, the left ocular positioned to permit the left eye to view a target, a right ocular is disposed in a portion of a right visual path for the right eye, the right ocular positioned to permit the right eye to view a target. The instrument can also include a wavefront sensor disposed on a translation stage, the wavefront sensor having an optical path to an imaging sensor, the translation stage being movable to position the optical path of the wavefront sensor in alignment with the portion of the left visual path in a first state and in alignment with the portion of the right visual path in a second state. One or more light sources are optionally provided for propagating light along a least part of the left and right visual paths to illuminate the left and right eyes.
