2、涼熱感：用舌尖輕輕舔鏡片，涼爽感較強(qiáng)是天然水晶，舔后涼即變溫的是仿造品。 </p> <p> 3、硬度：天然水晶硬度大，一般灰塵不易劃傷其表面，若發(fā)現(xiàn)鏡片上有輕微細(xì)小的劃痕，便有贗品之嫌。 </p> <p> 4，天然水晶有雜質(zhì),有石紋,色澤沒有人造的白.人造的基本上沒有雜質(zhì) </p> <p> 5，天然水晶片握在手中始終是涼的,而人造的就會(huì)變暖.3天然的水晶鏡片有瑕疵,那兩塊偏光鏡片夾住看的話就會(huì)看的到.做眼鏡的叫"霞"還有天然的是有一定的彎度的 </p> <p> 6，水晶石的硬度是7度，可在玻璃和一般金屬上隨意劃出痕跡，而仿制品則達(dá)不到這樣高的硬度 </p> <p> 7，水晶石熔點(diǎn)為1713攝氏度，放在火爐中鍛燒后再放人冷水中仍不炸裂；而仿制品無固定熔點(diǎn)，加熱至高溫后放人水中立即炸裂。 </p><p style="text-indent:25px">PC鏡片定義：一般的樹脂鏡片都是熱固性材料，即原料為液態(tài)，加熱后形成固態(tài)鏡片。PC片又叫“太空片”、“宇宙片”，化學(xué)名稱為聚碳酸酯，是熱塑性材料。即原料為固態(tài)，經(jīng)加熱后塑形為鏡片，所以這種鏡片成品后受熱過度也會(huì)變形，不適合高濕熱場(chǎng)合。PC鏡片有著極強(qiáng)韌性，不破碎（2cm可用于防彈玻璃），故又稱安全鏡片。比重每立方厘米*為2克，是目前用于鏡片的**輕材料。從鏡片的功能上講，它具有調(diào)節(jié)進(jìn)入眼睛之光亮，增加視力，保護(hù)眼睛安全和臨床***眼病的作用。對(duì)屈光異常引起的兒童斜視和伴有***的屈光異?；颊?，佩戴眼睛后均可***。而鏡片當(dāng)然要與鏡框搭配，還能起到美容、裝飾性的作用。現(xiàn)代流行者強(qiáng)調(diào)，眼睛要有與時(shí)代人的面部化妝及服飾的和諧，反映社會(huì)階層高、學(xué)問高雅、時(shí)尚等象征。二者的比率將影響PC/ABS材料的熱穩(wěn)定性。</p><div

（3）填料：在由兩部件組成的模子空間內(nèi)注入液態(tài)單體； </p> <p> （4）聚合：將注滿單體的模子放入爐內(nèi)接受幾小時(shí)的熱循環(huán)固化，對(duì)于某些材料 </p> <p> 可用紫外線輻射數(shù)分鐘，以使樹脂逐漸固化； </p> <p>

作為光學(xué)材料，水晶的比較大優(yōu)點(diǎn)是硬度大，制成的鏡片不易磨損。在本世紀(jì)20－30年代曾流行一時(shí)。因其制成的鏡片經(jīng)久耐用，又因其價(jià)格十分昂貴，常常留傳給下一代。 </p> <p> 在民間有：“水晶養(yǎng)目”之說。 </p> <p> 水晶的主要成分是SiO2，是一種天然透明礦物質(zhì)。 </p> <p> （1）水晶對(duì)紅外線、紫外線的吸收率差。 </p> <p> 對(duì)紫外線的吸收率*為14.5％，而玻璃對(duì)紫外線的吸收率是52％，目前加入U(xiǎn)V材料的樹脂鏡片對(duì)紫外線的吸收率已高達(dá)到90％以上. </p> <p> （2）天然水晶常含有雜質(zhì)，密度不均勻，會(huì)出現(xiàn)氣泡和條紋而產(chǎn)生雙折射現(xiàn)象，從而影響視力。 </p> <p> 由此可見，水晶不但不具有養(yǎng)目的作用，其對(duì)紫外線的高透過率是對(duì)眼睛有害的。在科學(xué)技術(shù)飛速發(fā)展的***，新的光學(xué)材料樹脂制作的眼鏡片，無論其光學(xué)性能、安全性能、防止有害射線保護(hù)眼睛的性能都遠(yuǎn)遠(yuǎn)優(yōu)于水晶廣東手機(jī)鏡片面板品質(zhì)保障</p></p><br
