Abstract

Recently, the interest in technologies for anti-fog lens coating has increased, owing to the inconvenience of lens fog occurrence while wearing a mask daily or at work. Consequently, many ocular products with anti-fog capability have been introduced into the market. However, their durability is poor or not specified, owing to the absence of a test method or standard for evaluating the durability of anti-fog coatings. In this study, a test method for evaluating the durability of anti-fog coating for lenses was proposed. The proposed method combines the durability test for anti-reflective coatings for lenses and the test for resistance to ocular fogging. The test results obtained for different coated lenses using the proposed method indicate that this method effectively evaluates anti-fog coating durability.
