、镜片材质

1、天然材料--水晶镜片:

这种材料的主要成份是二氧化硅,通常分为无色和茶色两种。材质不易磨损,热膨胀系数小。由于它对紫外线具有特有的透明度,佩戴时容易引起视疲劳。

主要材料有“托力克片”、“克罗克斯片”、“克罗克赛片”、“超薄片”、“1.60玻璃镜片”。具有比其它材质的镜片更耐刮的特性,但相对的其重量也较沉,其折射率相对高:普通片为1.523,超薄片为:1.72以上,最高可达2.0。其折射率比树脂镜片高,因此在同样度数情况下,玻璃镜片要比树脂镜片薄。玻璃镜片的透光率和机械化学性能都比较好,有恒定的折射率、理化性能稳定。没有颜色的镜片称光学白托(白片),有色片中的粉红片称克罗克赛镜片(红片)。克罗克赛镜片能吸收紫外线、对强光略有吸收作用。但是玻璃片易碎,材质偏重。

3、树脂片:

最具代表性的是CR-39,由硬而透明的材质制成,折射率为1.499,透光率为92%。从材质特点看,它具有较好的热稳定性,在150摄氏度以下不变形,耐水性、耐腐蚀性(除强酸)也较好,不溶于一般的有机溶剂。质轻,比重为1.32,是玻璃的二分之一,耐冲击、不易碎、安全感强(符合美国FDA标准),配戴舒适且加工方便,用途广(包。

括半框、无框镜架中使用),对紫外线的吸引能力高于玻璃镜片;热传导率低,由水蒸气引起的"水雾"的情况比玻璃镜片好一些。但是受材质影响,树脂片也存在不足之处:由于镜片耐磨性较差,表面易擦伤,而且镜片折射率低,相对比玻璃镜片要厚1.2-1.3倍。

4、PC片(碳酸聚脂镜片):

一般的树脂镜片都是热固性材料,即原料为液态,加热后形成固态镜片。PC片又叫“太空片”、“宇宙片”,化学名称为聚碳酸酯,是热塑性材料。即原料为固态,经加热后塑形为镜片,所以这种镜。

Hello everyone, today I'll introduce a very famous people, I think everybody should know him, MaiKeJieKeXun, is the elvis Presley after, western pop music's most influential musicians.
