This study added Au colloid in martial of conventional contact lens in various concentrations and copolymerized by heating at 70 ^oC for 40 minutes, 80 ^oC for 40 minutes, and finally, 100 ^oC for 40 minutes. Using the polymer produced through the copolymerization process, we have produced a contact lens and measured the physical characteristics which showed oxygen transmissibility of 9 ~ 12 × 10^-9 cm/s mL O₂/mL × mmHg, water content of 27.84% ~ 32.17%, refractive index of 1.432 ~ 1.443, visible transmittance of 83.2% ~ 89.5% and tensile strength of 0.141 kgf ~ 0.152 kgf. The polymer satisfied the physical properties required to produce contact lenses. Also, we judged that the polymer is suitable to be applied as a functional material for ophthalmological purposes.
