“…Polymethacrylates: Include, Polymethyl acrylate (PMA), PMMA, HEMA and pHEMA. Hybrid PMMA-dioxide systems have been reported widely (Table 1 and 2), focusing mostly on PMMA-SiO 2 (Soni et al, 2018), PMMA-TiO 2 (Fujita et al, 2015), PMMA-ZrO 2 (Gad et al, 2018). An organic polymer PMMA has synthesized with zirconium oxide nanocrystal by Otsuka and Chujo (2010) to get polymerized material PMMA/ ZrO 2 of above 95% visible light transmittance and increment in RI to 1.534 when applying 38.8 wt.% ZrO 2 content.…”

An overview of high Refractive Index (RI), high abbe number (low dispersion) (ν d) 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, ν d and light transmittance higher. This study shows the evolution of polymer properties used in optical applications and focuses on RI, ν d and transparency of the optical plastics that can be employed in the CLs fabrication or enhancement of them.

Contact lenses (CLs) are produced from optical polymers which recommended by experts to treat the refractive errors. Researchers are looking for ideal materials in order to improve the CLs optical qualities. This investigation gathers polymeric materials merits to choose the desired pure or doped polymer for the purpose of CLs manufacturing.Methods: high performance CLs can be made of polymers with high transparency nanocomposite because of the need for optical plastic merits such as light weight, transparency, Biocompatibility, the ability to modify its refractive index and abbe number.Results: TiO 2 -PMMA and TiO 2 -PHEMA nanocomposites can be considered the best candidate polymers in CLs fabrication due to its optical properties where it possesses RI higher than 1.52, νd of 30-54, transmittance higher than 92% and its flexibility and biocompatibility to the human eye tissues. Conclusion:this article demonstrates the advancement of polymer properties utilized in optical applications focusing on RIs, νd and visible light transmittance of the optical plastics that can be utilized in the CLs manufacture or evolution of them.

“…3 Graphite was incorporated into PMMA by solvent casting method by Soni et al With a rise in the concentration of graphite nanoparticles, both the direct optical band gap and the thin film's refractive index go down. 4 Alver et al made use of the solvent casting technique to introduce α-Fe 2 O 3 -ZnO into the PMMA matrix. UV-vis spectrophotometry showed that optical transmittance decreased as the reinforcing amount increased.…”

The objective of this study was to investigate the fundamental aspects of acrylic resin and zirconia nanoparticle interaction to analyze the optical properties and subsequent changes in refractive index with incremental loading of nanoparticles. Poly(methyl methacrylate) (PMMA) reinforced with zirconia nanoparticles were prepared by dip coating, spin coating and solvent casting techniques. An overall understanding of the polymer nanocomposite film has been achieved using the spectroscopic and morphological studies. The vital aspect of this whole study is to derive a simple yet an efficient nanocomposite film capable of imparting extraordinary optical properties. Within the limitations of this research a very crucial property of the material has been revealed. The RI as well as the optical transparency of the nanocomposite film has been steadily maintained with a significant increase of RI by the magnitude of 0.06 and ~100% light transmittance on incorporation of pure zirconia nanoparticles into PMMA matrix has been achieved. The best technique found was spin coating as it could yield thin films and better transparency and higher refractive index.
