Manufacturing method of a pair of spectacle lenses

Abstract

To provide a pair of spectacle lenses easily permitting binocular vision.SOLUTION: In a manufacturing method of a pair of spectacle lenses 1 comprising a right eye spectacle lens 10R used for a right eye and a left eye spectacle lens 10L used for a left eye, a lens design condition is obtained, where a difference between the sum obtained by adding a size of an in-range change area in which a change in a refractive index is within a predetermined range to a size of a clear vision area in which astigmatism is smaller than a predetermined value in a center side of the right eye spectacle lens 10R and the sum obtained by adding the size of an in-range change area to the size of a clear vision area in a center side of the left eye spectacle lens 10L becomes smaller than when designing the right eye spectacle lens 10R and the left eye spectacle lens 10L under a predetermined design condition, and the right eye spectacle lens 10R and the left eye spectacle lens 10L are designed and manufactured under the obtained lens design condition.SELECTED DRAWING: Figure 1
