Studies on Development of Polymeric Materials Using Gamma Irradiation for Contact and Intraocular Lenses

<table>Polymerization of HEMA and mixtures of HEMA with other monomers in the presence of water (i) solution of monomer or monomer mixture in water, (ii) hydrated polymer without entrapped water remains transparent, (iii) hydrated polymer with entrapped water appears opaque, and (iv) dehydrated polymer from both the hydrated, transparent and opaque polymers.</table>
