Abstract: An overview of high Refractive Index (RI), high abbe number (low dispersion) (νd) and high transmissivity optical plastics improved and used to get a perfect Contact Lens (CL) material and design, this review gathers optical plastics developments to choose the desired polymer in Cls applications. High performance CLs can be made of polymers with high transparency nanocomposites because of the need for optical plastic merits such as light weight, transparency, biocompatibility, the ability to modify its refractive index and Abbe number. Doping with nano-particles can be considered as a good candidate in CLs fabrication due to its rule in increasing the RI, νd and light transmittance higher. This study shows the evolution of polymer properties used in optical applications and focuses on RI, νd and transparency of the optical plastics that can be employed in the CLs fabrication or enhancement of them.
