Nanoparticle with antimicrobial property has been applied to various fields. This study added silver/platinum nanoparticles to HEMA (2-hydroxyethylmethacrylate), NVP (N-vinyl pyrrolidone) and MMA (methylmethacrylate) in various concentrations and copolymerized by heating at 70 degrees C for 40 minutes, 80 degrees C for 40 minutes, and finally, 100 degrees C for 40 minutes. The particle size of used nano silver and platinum was 10 similar to 20 nm respectively. Using the polymer produced through the copolymerization process, the authors have produced a contact lens and measured the physical characteristics which showed water content of 34.29 similar to 39.00%, refractive index of 1.422 similar to 1.430, visible transmittance of 78.8 similar to 92.5% and tensile strength of 0.149 similar to 0.179 kgf. The ophthalmic lens material produced using silver/platinum nanoparticles satisfied the basic physical properties required for contact lens application.
