Toric multifocal contact lenses |
摘要 |
The present invention provides a toric multifocal contact lens having a cylindrical optical power to correct astigmatism vision errors and a multifocal power to compensate for presbyopia. A toric multifocal contact lens of the invention has a central axis, an anterior surface having a first central optical zone, and an opposite posterior surface having a second central optical zone. The first central optical zone and the second central optical zone combine to provide a cylindrical optical power to correct astigmatism vision errors and a multifocal power to compensate for presbyopia.
