Described is a silicone hydrogel contact lens having non-uniform morphology. The contact lens may be made from a reactive mixture comprising: a silicone-containing component; a hydrophilic component; a non-reactive polymeric internal wetting agent; and a polymerization initiator, the contact lens having an oxygen permeability of at least about 60 barrers, and wherein the molar ratio in the lens of the polymeric non-reactive internal wetting agent to silicone, without a surface treatment, is greater in the lens's surface than in its bulk.
