A study on the optical properties of the PMMA polymer doped with some semi metal dioxides nanoparticles

This work on a compound polymer PMMA doped with some semi-metal oxides nanoparticles (SiO2, TiO2) NPs, intended to be utilized in corrective Contact Lenses. For this purpose the optical properties of (PMMA+2%SiO2, PMMA+2%TiO2, and PMMA+1%SiO2+1%TiO2) NPs were measured calculated get proper refractive indices dispersion (Abbe number) for these compounds design optimization.
