The invention belongs to the cornea contact lens especially for curing the hard permeability cornea. The CRGP is made up of the optical region, the middle circle part and the side arc region of the lens. The diameter of the optical region is 7.0-8.5mm and the radius of the base arc curvature is 8.7-9.2mm; the width of the middle circle is 1.5-1.8mm, the radius of the second arc curvature is 7.8-8.6mm; the width of the side arc is 0.3-0.5mm, the radius of the side arc curvature is 11-12.5mm. the whole diameter of the lens is 10.6-13.1mm and the thickness of the center is 0.08-0.18mm. So the center of the lens has the good location to decrease the higher image error efficiently. |
