Silicone hydrogel contact lenses (SiHy) are modern and advanced lenses with distinctive properties compared to
other lenses; The basis of their design is to have high oxygen permeability. In this paper, silicone-based contact
hydrogel lenses were fabricated by polymerizing 3- (methacryloxypropyl TRIS (trimethylsiloxy) silane (TRIS)
with N, 1-vinyl 2- pyrrolidone (NVP), Methacrylate (MA), 2-hydroxyethyl methacrylate, and 2-Hydroxyethyl
acrylate (HEMA). A feature for silicone hydrogel lenses has been studied through several laboratory tests to
ensure the validity of these lenses, including equilibrium water content, oxygen permeability, mechanical
properties, optical transparency, protein absorption, contact angle, and bacterial attachment. The
outcomesshowed which the TRIS component in each component raised oxygen permeability as well as reduced
the equilibrium water component, whilst (NVP& HEMA) -co-TRIS and increased equilibrium water content
(EWC)%. The highest oxygen penetration value was 140barrers, corresponding to a 86%equilibriumwater
content. Overall, the silicon hydrogels in this work showed adequate oxygen permeability as well as optical
transparency and anti-protein absorption. Therefore, polymers made of silicone hydrogel may have the potential
to be among the polymers made of contact lenses.
