TORIC OPHTHALMIC LENS |
摘要 |
A tonic ophthalmic lens is described in which refractivity of the lens differs between a first direction on a plane perpendicular to an optical axis of the lens and a second direction which differs from the first direction on the plane. In addition, refractivity difference which is the difference between the refractivity in the first direction and the refractivity in the second direction varies depending on a position of the lens in a radial direction. |
