    摘要: A soft contact lens for use on the human eye formed from a soft material like silicon or a hydrophilic material. The lens has a generally spherical concave inner surface which conforms to the cornea and a generally convex outer surface. To maintain the correct orientation of the lens when placed on the eye it is provided with a flattened region along a portion of its periphery.
