Document Type and Number:
Japanese Patent JP4954419
Kind Code:
B2
Abstract:
What is described here is a method of manufacturing spectacles comprising individual progressive ophthalmic lenses, including the following steps:selection of a spectacle frame,detection of the shape of the lens rings with a precision better than ±0.5 mm in the x- and y-directions (data set 1),detecting the intersection points of the lines of sight through the plane of the lens rings for at least two design distances of the progressive ophthalmic lenses with a precision better than ±1 mm (data set 2)selection and positioning relative to the lens rings of a spherical or non-spherical surface in view of the prescription data, using the data sets 1 and 2 (data set 3),computing and positioning the progressive surface relative to the selected surface, with minimization of the critical thickness of the ophthalmic lens, using the data sets 1 to 3 (data set 4),manufacturing the progressive surfaces as well as edges of the ophthalmic lenses from a non-edged semi-finished product finished on one side, using the data sets 1 to 4.
