Ophthalmic Lens Having At Least A Stable Zone |
| 摘要 |
Ophthalmic lens having a first surface comprising a zone of optical interest, the zone of optical interest comprising at least: a far vision control point (FV), a near vision control point (NV), a main line (M) starting from one end of the zone of optical interest, ending on the opposite end of the zone of optical interest and passing through the far and near vision control points, wherein the main line (M) comprises at one end a first section (S1) of continuous increase of mean sphere, at the other end a second section (S2) of continuous increase of mean sphere, the first and second section being separated by a third section (S3) of stabilized mean sphere. |
