PROBLEM TO BE SOLVED: To provide a transparent optical element for facial protection in which reflected light quantity is small even under a lighting system with very high intensity used during surgical operation, dental treatment or the like, and which has defogging performance.SOLUTION: An optical element 1 for facial protection has a plurality of structures 12 at a pitch that is not more than the wavelength of visible light on both surfaces of a flexible transparent substrate (base 11). The structures 12 are formed from a resin cured material having a hydrophilic functional group.COPYRIGHT: (C)2014,JPO&INPIT【課題】外科手術時や歯科治療時等の非常に強度の高い照明システム下でも反射光が少なく、かつ防曇性能を持つ透明な顔面保護用光学素子を提供する。【解決手段】顔面保護用光学素子1は、可撓性を有する透明基材(基体11)の両面に、可視光の波長以下のピッチで複数の構造体12を有する。構造体12は、親水性官能基を有する樹脂硬化物で形成されている。【選択図】図1
