Contact lenses with surfaces having different softness |
| abstract |
The invention is related to a contact lens, especially a SiHy contact lens, which comprises a lens bulk material covered with an outer surface hydrogel layer thereon and has a posterior surface and an opposite anterior surface. The outer surface hydrogel layer consists of an anterior outer hydrogel layer and a posterior outer hydrogel layer. A contact lens of the invention is characterized by having a difference in surface softness between its posterior (BC) and anterior (FC) surfaces. |
