產品簡介YAMASHIRO EXTRA TAC 防霧貼片，採用日本液晶產業使用的 TAC 光學薄膜製造，透明度極高、變形極低，觀感明亮護眼。貼片同時具備感光變色（photochromic）功能：紫外線強時數秒內迅速轉深，紫外線弱時回復透明，而回復透明的速度配合瞳孔調節而較慢，有助減輕眼睛疲勞。主要特點 感光變色：透光度隨紫外線強度自動調節 數秒內迅速變深，回復透明速度較慢，減輕眼睛疲勞 對少量紫外線亦有反應，兼容大部分具 UV 阻隔功能的原廠鏡片（部分型號除外） 免工具安裝，直接貼於頭盔鏡片（shield）即可 通用設計，符合樣板尺寸的鏡片均可安裝 物料不易隨時間劣化，防霧效果持久 高吸濕 TAC 薄膜配合空氣層，雙重防霧：阻隔溫差結露並吸走鏡片表面濕氣 規格 Specifications 尺寸 Size：W265 × H85 mm 物料 Material：Anti-fog TAC film 防霧 TAC 薄膜 注意 Note：弧度過急或半徑過小的鏡片或未能安裝 EnglishEXTRA TAC is a photochromic anti-fog sheet made from Japanese TAC film — the optical-grade material used in LCD technology, offering high transparency and very low distortion. Its transmittance changes with the amount of UV light: it darkens to smoke in just a few seconds, while returning to clear more slowly in line with the movement of the pupil, reducing eye fatigue. No tools are required — simply stick it onto your shield. Photochromic: reacts even to small amounts of UV, so it also works with most UV-blocking genuine shields (some exceptions) Tool-free, stick-on installation with a universal design Highly hygroscopic TAC film plus an insulating air layer for double anti-fog action Durable material keeps the anti-fog effect for a long time Size: W265 × H85 mm Note: may not fit shields with a steep curve or tight radius 圖片及介紹只供參考，一切以實物為實。歡迎向我們店員查詢。Images and descriptions are for reference only; the actual product shall prevail.
