By applying the test methods of "Protection Eyewear Standard (KS P 8147)", "Glasses Frame Standard (KS G 3306)" and "Lens Standard for Sunglasses (KS P 4404)", this study analyzed optical functions of sunglasses now being sold in a road shop (A shop), a fashion goods store (B shop), a shop of highway rest area (C shop) and an optical shop (D shop). When compared with sunglasses (UV transmittance rate 8.8%) of a road shop, UV Block effects of sunglasses (UV transmittance rate 0.7%) of an optical shop showed good results. In addition, the average surface resistance against abrasion for sunglasses which was sold at an optical shop was 1.4% that was much higher than that of sunglasses of a road shop(2.2%).
