近(jin)視(shi)(shi)鏡(jing)(jing)(jing)(jing)戴著是(shi)否(fou)舒服、看(kan)得是(shi)否(fou)清楚，鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)材(cai)質是(shi)核心的(de)因素。現今鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)材(cai)質比較(jiao)多(duo)，常見的(de)有玻璃鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)、樹脂鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)、水(shui)晶鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)、太空鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)、MR鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)這五種(zhong)，對于(yu)大多(duo)數人(ren)來說，對于(yu)這些近(jin)視(shi)(shi)眼鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)不(bu)太了解，因而選擇近(jin)視(shi)(shi)眼鏡(jing)(jing)(jing)(jing)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)的(de)事后(hou)也(ye)就比較(jiao)糾結，下面來看(kan)一下這五種(zhong)鏡(jing)(jing)(jing)(jing)片(pian)(pian)(pian)(pian)材(cai)質的(de)介紹。

不管(guan)是哪種鏡(jing)片(pian)(pian)都(dou)會有(you)一些缺點，而(er)在(zai)鏡(jing)片(pian)(pian)上鍍鏡(jing)片(pian)(pian)膜就(jiu)能改(gai)善鏡(jing)片(pian)(pian)的(de)(de)光(guang)學特性。目(mu)前(qian)常見的(de)(de)鏡(jing)片(pian)(pian)膜有(you)很多(duo)種，常見的(de)(de)有(you)增透膜、加硬膜、抗污膜、防藍光(guang)膜等。好點的(de)(de)鏡(jing)片(pian)(pian)都(dou)是使(shi)用的(de)(de)多(duo)層鍍膜，使(shi)得鏡(jing)片(pian)(pian)有(you)多(duo)種效果。

鏡(jing)片的屈光度即我們平時說的度數(shu)是(shi)鏡(jing)片最(zui)重要(yao)(yao)的一(yi)個(ge)參數(shu)。一(yi)個(ge)屈光度等于(yu)我們平常所(suo)講的100度，視力問題越嚴重，需要(yao)(yao)的鏡(jing)片度數(shu)也(ye)(ye)越深，鏡(jing)片厚度也(ye)(ye)會越高。驗光配鏡(jing)的目的也(ye)(ye)就(jiu)是(shi)解決看(kan)遠的問題，所(suo)以(yi)配鏡(jing)就(jiu)有一(yi)個(ge)原則，也(ye)(ye)就(jiu)是(shi)以(yi)看(kan)清5米處1.0的視力表的最(zui)低度數(shu)為依據。
