Although the use of silicone hydrogel contact lenses which are known to have high oxygen transmissibility is increasing, they are being sold without any product labeling of physical properties such as water content and oxygen transmissibility. To analyze the physical properties such as the water content and oxygen transmissibility of approved silicone hydrogel contact lenses, this study collected and analyzed the approval information published on the KFDA website. Of 68 cases of domestic silicone hydrogel contact lenses analyzed in this study, 61 cases (89.7%) did not meet the international standard for oxygen permeability. This is because lenses that are not different from hydrogel contact lenses were submitted for approval as silicone hydrogel contact lenses because there is no domestic standard for silicone hydrogel contact lenses. In future, besides the information published on the website, analysis of the physical properties of a wide variety of actual silicone hydrogel contact lenses on the market is required.
