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.
