TORIC CONTACT LENSES |
摘要 |
A toric contact lens includes a posterior surface and an anterior surface, one of these surfaces including a toric optical zone, and these surfaces being shaped to form a ballast. A diameter of the posterior optical zone and a diameter of the anterior optical zone are selected to minimize thickness of the lens based on the cylindrical correction of the lens.
