Patent ID: 8118427

Claim:
A method for determining an optimal eyeglass lens design for a viewer, where a design of a lens imparts optical correction of the lens, the method comprising the successive steps of: showing the viewer a stereoscopic scene including optical effects of a first lens design; introducing a relative movement between the viewer and the shown stereoscopic scene, said scene being shown with optical effects of the first lens design, so as to take into account how things are seen while wearing a lens with the first lens design; obtaining the viewer's opinion of the first lens design; showing the viewer a stereoscopic scene including optical effects of a modified lens design; introducing a relative movement between the viewer and the shown stereoscopic scene, said scene being shown with the modified lens optical effects so as to take into account how things are seen while wearing a lens with the modified lens design; obtaining the viewer's opinion of the modified lens design; repeating the three last steps up to viewer's satisfaction.
