This invention relates to a manufacturing method of substrate having anti-fog coating layer and the constituent structure thereof. The method uses cellulose acetate to form an anti-fog coating layer of a predetermined configuration and thickness on the substrate of lens, wherein the thickness is better lying between 0.1-0.3 mm in practice, and performs lamination of the anti-fog coating layer with the electroplating-treated lens (i.e. the substrate layer) to constitute the substrate of lens. The overall thickness of the substrate of lens can be substantially thinned and can be kept with the preset anti-for characteristics of the original lens even after being repeatedly cleaned and/or wiped for a long period of time.一種具防霧膜層之基材的製作方法及其組成結構,是對鏡片基材可藉Cellulose Acetate(醋酸纖維)成形出預設形態及厚度的防霧膜層〔大約介於0.1~0.3mm為較佳實施〕,再將該防霧膜層與施以電鍍之類處理過的鏡片(即基材層)作一貼合,即可構成一鏡片基材,而該鏡片基材的整體厚度能具體薄化,且即使經一段長時間的重複清洗/或擦拭,仍可保持原先鏡片預設的防霧特質。1‧‧‧防霧膜層2‧‧‧基材層3‧‧‧黏膠4‧‧‧鏡片基材
