Abstract
A container for storing a silicone hydrogel contact lens in a liquid, having a bowl portion with a radius such that the radius of the lens is from about 85 percent to about 100 percent of the inner surface radius. The bowl portion has an outer section which is defined by a radius larger than the inner surface radius. Furthermore, the bowl portion has a roughness sufficient to maintain capillary attraction of the lens to the bowl portion but preventing adhesion of any portion of the front surface of the lens to the bowl portion.
