<p>A rigid gas-permeable cornea contact lens comprises a peripheral cambered zone (2) of the lens (1). Two symmetric stabilization wing zones (3) or three stabilization wing zones (3) are arranged on the inner edge of the peripheral cambered zone (2) of the contact lens. The concave inner cambered-surface of the stabilization wing zone (3) is a conical cambered-surface, a spherical cambered-surface or an aspherical cambered-surface. The structure of the cornea contact lens increases the stability of the contact lens on the cornea and enables the contact lens to be centered easily, thus the state that the contact lens fits to the cornea is more desirable and the optimal state of eyesight is achieved.</p> |
