ABSTRACT:
A contact lens comprising a lens substrate in shape of a lens which comprises a triorganovinylsilane based polymer, said lens substrate having a hydrophilic polymeric chain grafted onto the surface thereof. 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.
