Method of determining an ophthalmic lens

摘要

The present disclosure provides systems and methods for determining an ophthalmic lens. In one implementation, three-dimensional coordinates of a center of rotation of the wearer's eye measured on the wearer in binocular vision are received. At least one direction of gaze measured in a natural posture and a determined position of the ophthalmic lens are received. Characteristics of the ophthalmic lens are calculated by using the coordinates measured for the center of rotation of the eye, the determined position of the lens, and the at least one direction of gaze measured in a natural posture. The characteristics of the ophthalmic lens are calculated by positioning a starting ophthalmic lens in the determined position and modifying the starting ophthalmic lens by wavefront analysis and/or optimizing using ray tracing dependent on the coordinates measured for the center of rotation of the eye and the determined position of the lens.

1. A method for determining an ophthalmic lens for an eye of a wearer, the method comprising the steps of:
measuring, on the wearer in binocular vision, three-dimensional coordinates of a center of rotation of the wearer's eye; measuring at least one direction of gaze in a natural posture; determining a desired position of the ophthalmic lens; and calculating characteristics of the ophthalmic lens by using the coordinates measured for the center of rotation of the eye, the determined position of the lens and the at least one direction of gaze measured in a natural posture, the characteristics of the ophthalmic lens calculated by positioning a starting ophthalmic lens in the determined position and at least one of modifying the starting ophthalmic lens by wavefront analysis or starting from the starting ophthalmic lens, optimizing using ray tracing dependent on the coordinates measured for the center of rotation of the eye and the determined position of the lens.
