學(xué)名碳本酸丙烯乙酸，或稱烯丙基二甘醇酸脂（Dially?Glycol?Carbonates），是應(yīng)用*****的生產(chǎn)普通樹脂鏡片的材料。它于四十年代被美國哥倫比亞公司的化學(xué)家發(fā)現(xiàn)，是美國空軍所研制的一系列聚合物中的第39號(hào)材料，因此，被稱為CR-39（哥倫比亞樹脂第39號(hào)）。CR-39被用于生產(chǎn)眼用矯正鏡片是在1955~1960年，是***代的超輕、抗沖擊的樹脂鏡片。CR-39作為一種熱固性材料，單體呈液態(tài)，在加熱和加入催化劑的條件下聚合固化。聚合是一個(gè)化學(xué)反應(yīng)，即由幾個(gè)相同分子結(jié)構(gòu)的單體組成的一個(gè)新的聚合體分子，具有不同的長度和性質(zhì)。作為光學(xué)鏡片，CR-39材料性質(zhì)的參數(shù)十分適宜：折射率為1.5（接近普通玻璃鏡片）、密度1.32（幾乎是玻璃的一半）、阿貝數(shù)為58~59（只有很少的色射）、抗沖擊、高透光率，可以進(jìn)行染色和鍍膜處理。?它主要的缺點(diǎn)是耐磨性不及玻璃，需要鍍抗磨損膜處理。樹脂鏡片可采用模式壓法加工鏡片表面的曲率，因此很適用于非球面鏡片的生產(chǎn)。廣東批發(fā)鏡片面板外殼輔助功能：可進(jìn)行多種良好的功能化添加處理，使鏡片具有防有害射線、變色等功能.</p><div

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）水晶對紅外線、紫外線的吸收率差。 </p> <p> 對紫外線的吸收率*為14.5％，而玻璃對紫外線的吸收率是52％，目前加入U(xiǎn)V材料的樹脂鏡片對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，其對紫外線的高透過率是對眼睛有害的。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 </p><p> 光致變色玻璃材料鏡片特點(diǎn)光致變色現(xiàn)象是通過改變材料光線吸收屬性，使材料對太陽光強(qiáng)度作出反應(yīng)的一種性質(zhì)。它的基本原則是使普通的玻璃（包括塑料光致變色材料）在紫外線輻射的影響下顏色變深，以及在周圍高溫的影響下顏色變淡，這兩個(gè)過程是可逆的，而且可能一直存在。這一現(xiàn)象是通過***在材料中混合光致變色物質(zhì)的分子而完成。1962年出現(xiàn)了***代光致變色玻璃材料,此后性能不斷得到改良。其主要是在玻璃材料中加入了鹵化銀晶體。這些晶體在紫外線擊幅射下起化學(xué)反應(yīng)，鏡片的顏色變深。***代光致變色玻璃材料的變色原理是銀原子和氯原子之間的一種電子交換，通過氯化銀和周圍的環(huán)境表現(xiàn)。在沒有光線條件下，氯化銀呈離子態(tài)，因銀離子是透明的，所以鏡片也是透明的；而在紫外線輻射下，不穩(wěn)定電子離開了氯離子，與銀離子結(jié)合為金屬銀并吸收光，鏡片則變深。當(dāng)紫外線輻射減弱，移動(dòng)電子離開銀原子返回氯原子，鏡片逐漸恢復(fù)了原先的清澈狀態(tài)。對一般光致變色玻璃，變色同時(shí)也受到溫度控制，在光照度不變時(shí)，溫度越低則顏色越深。光致變色材料大多是灰色和棕色的，俗稱灰變和茶變，其它的顏色也可以通過專門的工藝達(dá)到。所有的眼鏡片。無機(jī)物：低分子單體以分子鍵相互間結(jié)合.</p><div

鏡片材料采用透明的介質(zhì)，主要分為無機(jī)和有機(jī)二大類。在我們的日常生活還會(huì)碰到一種天然介質(zhì)水晶鏡片，這是用石英礦磨制成的鏡片。古代有水晶能養(yǎng)顏明目的說法，但事實(shí)上水晶的主要成分是二氧化硅（sio2），比較大優(yōu)點(diǎn)是硬性度高且不易受潮，但紫外線及紅外線的透過率較高，而且水晶中密度不均勻，含雜質(zhì)，有條紋及氣泡等到產(chǎn)生，會(huì)形成雙折射現(xiàn)象，從而影響視力。無機(jī)材料--玻璃，玻璃是非常特殊的不定型材料，在常溫下呈現(xiàn)固體，堅(jiān)硬但易碎，在高溫下具有粘性。玻璃沒有固定的化學(xué)結(jié)構(gòu)，因而沒有確切的熔點(diǎn)。隨著溫度的上升，玻璃材料會(huì)變軟、粘性增加，并逐漸由固體變?yōu)橐后w，這種逐漸變化的特性我們稱之為"玻璃狀態(tài)"。這一特性意味著玻璃在高溫時(shí)可以被加工和鑄型。玻璃材料制成的鏡片具有良好的透光性、表面拋光后更加透明的優(yōu)點(diǎn)
