A composition which is hydrophobic but possesses excellent wettability comprising copolymers and terpolymers of a polysiloxane and esters of acrylic and methacrylic acids. These compositions are suitable for use as ocular membranes worn in contact with the eye which possess excellent oxygen permeability, light transmission, wettability, mucophobicity, and lipophobicity and which can be worn for extremely long periods of time and then disposed of. A method of preparing the ocular membranes is disclosed, in which the composition is place between disposable molds and cured therein. The cured, mechanically and optically finished ocular membranes are recovered by the destruction of said molds and without secondary operations. The ocular membrane is a flexible, oxygen-permeable, membrane, adapted to be inserted on the eye and worn thereon continuously for extended periods.
