A kind of substrate of the antifog film layer of tool, it is the antifog film layer (about 0.1 ~ 0.3mm of Jie's what is preferably to implement) that can shape default form and thickness by acetate fiber (Cellulose Acetat) to lens substrate, the antifog film layer is bonded with plating etc processed eyeglass (i.e. substrate layer) work one is imposed again, it may make up a lens substrate, and the specific thinning of integral thickness energy of the lens substrate, and even if repeated washing/or wiping through a rapid lapse of time, can still keep the preset antifog speciality of original eyeglass.一種具防霧膜層之基材，是對鏡片基材可藉醋酸纖維(Cellulose Acetat)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。
