Patent number: 11391968Abstract: A spectacle lens including a prism prescription that has an eyeball-side optical surface. When one side is the same side as a prism base direction (nose side) and the other side is an opposite side of the prism base direction with a direction orthogonal to the prism base direction passing through a prism measurement reference point as a boundary, a minimum value of a curvature of the eyeball-side optical surface is on the same side as the prism base direction (nose side). Since a mean curvature becomes smaller in the prism base direction than a mean curvature of the prism measurement reference point and becomes larger in the opposite direction than the mean curvature of the prism measurement reference point across the prism measurement reference point, deviation in line of sight between right and left eyes is resolved.Type: GrantFiled: June 6, 2017Date of Patent: July 19, 2022Assignee: HOYA LENS THAILAND LTD.Inventors: Takashi Hatanaka, Tomohiro Odaira

Patent number: 9733490Abstract: A spectacle lens design system includes a first photographing apparatus having a first distance to the subject to photograph the subject and a second photographing apparatus having a second distance to the subject to photograph a visual target. The second distance is farther than first distance. The system determines a position of a subject's eye based on an image of the first photographing apparatus and tentatively calculates a position of the visual target based on an image photographed by second photographing apparatus. The system designs a shape of spectacle lens based on predetermined prescription information and calculated visual line information, where the visual line information is determined based on a determined position of eye and a position of the visual target moved in pseudo manner.Type: GrantFiled: February 28, 2014Date of Patent: August 15, 2017Assignee: HOYA CORPORATIONInventors: Hidetoshi Nishimura, Tomohiro Odaira
