Abstract
A hydrophilic polymeric contact lens contg. 50-98 wt.% water when swollen contains a ring (I) which does not infringe on the central, optically effective zone. (I) has a higher elasticity modulus than the hydrophilic polymeric base material (II) and is coated on at least one side pref. the inner side with (II). The largest ring diameter is pref. smaller than the lens diameter and the edge of the lens is pref. made of (II). The lens has greater stiffness without any reduction in permeability.
