Unverified'仿棉麻遮光'与'真棉麻'需区分：真棉麻天然材质多不全遮光（透光），标称棉麻质感又全遮光的基本是聚酯纤维仿制加涂层，介意材质者需看成分表涤纶占比79% similarUnverified双面桑蚕丝材质本身不含遮光填充层，遮光效果通常弱于海绵/记忆棉类眼罩，对遮光要求高的人不适合79% similarUnverified材质为聚酯纤维网面，透明度依赖网眼密度而非全透明薄膜，内容物可识别但不如PVC/EVA材质袋清晰可见75% similarUnverified遮光原理分两类：银胶/黑胶涂层布靠背面涂层遮光（涂层可能开裂脱落，怕高温），高密度提花/黑丝布靠织物本身密度遮光（更耐用、可水洗但价格高），追求长期耐用选后者75% similarUnverified遮光原理选涂层还是高密织造：涂层布（银胶/黑胶）遮光率高但透气差、久用可能开裂脱落；高密提花织物遮光约90%但更耐用透气、可水洗，长期使用优先高密织造75% similar
