Abstract

This research evaluated and synthesized a contact lens material based on polymers. The foundation substance is polymethyl methacrylate, or PMMA. In order to increase the total refractive index of the lens, silicon dioxide (SiO2) nanoparticles with an average diameter of 30 nm were added. The PMMA has been supplemented with concentrations of 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% of SiO2 nanoparticles. Investigations were conducted on how various SiO2 concentrations affected the optical properties of PMMA lenses. An analysis using spectroscopy was performed to determine the impact of varying SiO2 concentrations on the lens’s characteristics. By utilizing Zemax programs, this research investigated how the synthesized lens material behaved in various conditions. Through simulation, this research found the correlation between material composition as well as optical performance through revealing the amount of SiO2 nanoparticles. Based on the research experimental and theoretical evaluation, an ideal concentration of SiO2 of 3% was determined for the highest modulation, henceforward, the optimum lens material. This result showed the impacts of adding SiO2 nanoparticles to PMMA in boosting the refraction index of the lenses without ignoring their optical belongings.
