The characteristics of anisole group and hydrogel monomers by ratio in order to check their commerciality and their utilization as additives were investigated. The 2-hydroxy ethyl methacrylate(HEMA), Ethylene glycol dimethacrylate(EGDMA), Methyl methacrylate(MMA) and Methacrylic acid(MA) were basic unions, Azobisobutyronitrile (AIBN) was used as an initiator. In addition, the additives 2-, 3- and 4-Methylanisole were added at 1 to 10% ratio to combine them with thermal polymerization. After measuring the refractive index, water content, and spectral transmittance rate of each specimen manufactured, the results were compared and analyzed in proportion. As a result of measurement of the manufactured contact lens, the refractive index of the 2MET sample was 1.4169 ~ 1.4221, the water content was 44.71 ~ 45.92%, and the spectral transmittance in the visible light range was 90.87 ~ 91.14%. The 3-MET sample has a refractive index of 1.4216 ~ 1.4249, a water content of 40.96 ~ 43.99 and spectral transmittance of 90.26 ~ 93.72% in visible light region. The 4-MET sample has a refractive index of 1.4064 ~ 1.4205, a water content of 44.34 ~ 45.73%, and a Spectral transmittance of 94.06 ~ 92.79% in visible light region. In case of 4-MET sample, the water content decreased as the proportion of additives increased, while the 2-MET and 3-MET increased. In particular, The 2-MET sample has a much higher water content than 3-MET and 4-MET in the same proportions, thus it can be used as a material for high-functional contact lenses.
