- The physical and optical properties of functional hydrogel lenses manufactured using Gallate and Carotenoid group materials as additives for hydrogel lenses were analyzed. In order to manufacture a hydrogel lens, a hydrophilic monomer, HEMA (2-hydroxyethyl methacrylate), a cross-linker EGDMA (ethylene glycol dimethacrylate), and a photoinitiator 2H2M (2-hydroxy-2-methylpropyphenone) were used. Additives such as Epigallocatechin gallate, Octyl gallate, and Astaxanthin were added to the basic mixed solution at a ratio, respectively, and photopolymerized with a wavelength of 365 nm for 40 seconds by a cast mold method. The Carotenoid material produced a nano dispersion through the solvent substitution method, and the physical properties of the manufactured contact lens were evaluated by measuring refractive index, water content, spectral transmittance, and contact angle to analyze the changes in physical properties according to the material. Hydrogel contact lenses using the gallate group showed increased wettability and high UV blocking ability compared to base hydrogel lenses. In addition, lenses with epigallocatechin gallate added produced a gradually darker pink color as the amount added increased. Hydrogel lenses using carotenoid nano dispersions showed an increase in both refractive index and water content, and a tendency toward higher wettability. In addition, contact lenses manufactured using an optimized blending ratio of gallate and carotenoid showed increased refractive index, water content, and wettability, as well as antibacterial function and improved UV blocking ability. Hydrogel lenses are manufactured by adding gallate and carotenoid to basic lens material in the ratio can be used as functional medical eye materials with high refractive index, water content, wettability, UV blocking properties, and antibacterial properties.
