近視鏡(jing)戴(dai)著是否舒服、看得是否清楚，鏡(jing)片(pian)(pian)(pian)(pian)材(cai)質是核(he)心的因(yin)素(su)。現(xian)今鏡(jing)片(pian)(pian)(pian)(pian)材(cai)質比較(jiao)多，常見的有玻(bo)璃鏡(jing)片(pian)(pian)(pian)(pian)、樹脂鏡(jing)片(pian)(pian)(pian)(pian)、水晶鏡(jing)片(pian)(pian)(pian)(pian)、太(tai)空鏡(jing)片(pian)(pian)(pian)(pian)、MR鏡(jing)片(pian)(pian)(pian)(pian)這五種(zhong)，對于(yu)大多數人(ren)來(lai)說，對于(yu)這些(xie)近視眼鏡(jing)片(pian)(pian)(pian)(pian)不太(tai)了解，因(yin)而選擇近視眼鏡(jing)鏡(jing)片(pian)(pian)(pian)(pian)的事后也就比較(jiao)糾(jiu)結(jie)，下面來(lai)看一下這五種(zhong)鏡(jing)片(pian)(pian)(pian)(pian)材(cai)質的介紹(shao)。

不管是哪種(zhong)(zhong)鏡(jing)(jing)片(pian)(pian)(pian)(pian)都會有一些缺點(dian)，而在鏡(jing)(jing)片(pian)(pian)(pian)(pian)上鍍鏡(jing)(jing)片(pian)(pian)(pian)(pian)膜(mo)就能(neng)改善(shan)鏡(jing)(jing)片(pian)(pian)(pian)(pian)的光學特(te)性。目(mu)前常(chang)見(jian)的鏡(jing)(jing)片(pian)(pian)(pian)(pian)膜(mo)有很多種(zhong)(zhong)，常(chang)見(jian)的有增透膜(mo)、加硬(ying)膜(mo)、抗污(wu)膜(mo)、防藍光膜(mo)等(deng)。好(hao)點(dian)的鏡(jing)(jing)片(pian)(pian)(pian)(pian)都是使用的多層鍍膜(mo)，使得鏡(jing)(jing)片(pian)(pian)(pian)(pian)有多種(zhong)(zhong)效果。

鏡(jing)(jing)片(pian)的(de)(de)屈光(guang)度(du)(du)即我(wo)們(men)平時(shi)說的(de)(de)度(du)(du)數(shu)是鏡(jing)(jing)片(pian)最重(zhong)要的(de)(de)一(yi)個參數(shu)。一(yi)個屈光(guang)度(du)(du)等于我(wo)們(men)平常所(suo)講的(de)(de)100度(du)(du)，視力問題越(yue)嚴(yan)重(zhong)，需要的(de)(de)鏡(jing)(jing)片(pian)度(du)(du)數(shu)也越(yue)深，鏡(jing)(jing)片(pian)厚度(du)(du)也會(hui)越(yue)高。驗光(guang)配鏡(jing)(jing)的(de)(de)目(mu)的(de)(de)也就(jiu)是解決看遠的(de)(de)問題，所(suo)以(yi)(yi)配鏡(jing)(jing)就(jiu)有一(yi)個原則，也就(jiu)是以(yi)(yi)看清(qing)5米處1.0的(de)(de)視力表的(de)(de)最低度(du)(du)數(shu)為依據。
