ABSTRACT OF THE DISCLOSURE A contact lens comprises a lens substrate of a triorganovinylsilane based polymer, said lens substrate having a hydrophilic polymeric chain grafted onto the surface thereof. Such a lens is prepared by first preventing the lens substrate possibly by cutting and shaping a moulding button but more preferably by casting a flat film and then molding it to a lens, and thereafter activating the surface by a low-temperature gas plasma or by a photosensitizer and subsequently exposing it to a solution or vapor of the hydrophilic monomer. This contact lens is not only excellent in oxygen permeability, mechanical strength, dimensional stability, vision correcting ability, staining resistance and handleability, but also good in affinity with eyes due to good hydrophilic property possessed by the surface, which can be worn continuously for a long time.
