一、太陽鏡鏡片什么材質的好

太陽鏡(jing)(jing)鏡(jing)(jing)片(pian)(pian)(pian)一般采用塑(su)料鏡(jing)(jing)片(pian)(pian)(pian)、玻(bo)璃鏡(jing)(jing)片(pian)(pian)(pian)、偏光(guang)鏡(jing)(jing)片(pian)(pian)(pian)、變色鏡(jing)(jing)片(pian)(pian)(pian)制作。塑(su)料鏡(jing)(jing)片(pian)(pian)(pian)輕巧(qiao)不易碎，防(fang)紫外線功(gong)能優于玻(bo)璃鏡(jing)(jing)片(pian)(pian)(pian)，耐磨(mo)性差(cha)；玻(bo)璃鏡(jing)(jing)片(pian)(pian)(pian)其光(guang)學性能很穩定(ding)，不易變形，但是易破碎；偏光(guang)鏡(jing)(jing)片(pian)(pian)(pian)視線更清(qing)晰；變色鏡(jing)(jing)片(pian)(pian)(pian)可以根據光(guang)的強弱自動調節。

二、太陽鏡和偏光鏡的區別

太(tai)陽(yang)鏡(jing)就(jiu)是人們熟知用(yong)于(yu)遮擋(dang)陽(yang)光(guang)(guang)(guang)(guang)和紫外線(xian)的有(you)(you)色眼(yan)鏡(jing)，不能(neng)避(bi)免(mian)眩(xuan)光(guang)(guang)(guang)(guang)對眼(yan)睛的傷害(hai)(hai)。 而(er)偏(pian)光(guang)(guang)(guang)(guang)鏡(jing)能(neng)徹底濾(lv)除(chu)眩(xuan)光(guang)(guang)(guang)(guang)，達(da)到(dao)對眼(yan)睛的真正保護。 太(tai)陽(yang)鏡(jing)只(zhi)是利用(yong)減(jian)光(guang)(guang)(guang)(guang)的作(zuo)用(yong)，降(jiang)低(di)了有(you)(you)害(hai)(hai)光(guang)(guang)(guang)(guang)線(xian)的強度，并沒(mei)有(you)(you)阻(zu)隔有(you)(you)害(hai)(hai)光(guang)(guang)(guang)(guang)線(xian)。偏(pian)光(guang)(guang)(guang)(guang)眼(yan)鏡(jing)可(ke)以(yi)完全阻(zu)隔散射、曲折(zhe)和反射等各種因素造(zao)成的刺眼(yan)眩(xuan)光(guang)(guang)(guang)(guang)，即使(shi)長期從事強光(guang)(guang)(guang)(guang)活(huo)動，眼(yan)睛也可(ke)以(yi)得(de)到(dao)保護。偏(pian)光(guang)(guang)(guang)(guang)鏡(jing)含有(you)(you)偏(pian)光(guang)(guang)(guang)(guang)夾(jia)片，能(neng)夠(gou)解決近視問(wen)題，而(er)太(tai)陽(yang)鏡(jing)沒(mei)有(you)(you)此優勢。

三、太陽鏡的作用是什么

太(tai)陽(yang)鏡，也稱(cheng)遮(zhe)陽(yang)鏡，作遮(zhe)陽(yang)之用(yong)。人在(zai)陽(yang)光(guang)(guang)下通常要靠調節瞳孔大小來(lai)調節光(guang)(guang)通量，當(dang)光(guang)(guang)線強度超(chao)過(guo)人眼調節能力，就會對人眼造成傷害。所以在(zai)戶(hu)外活動場所，特別是在(zai)夏(xia)天，需(xu)要采用(yong)遮(zhe)陽(yang)鏡來(lai)遮(zhe)擋(dang)陽(yang)光(guang)(guang)，以減(jian)輕眼睛調節造成的(de)(de)疲勞或強光(guang)(guang)刺激造成的(de)(de)傷害。

四、太陽鏡怎么挑選

具有UV400標章認證的太陽眼鏡才是真正能有功效的太陽眼鏡，可隔絕99%以上紫外線。鏡面顏色為灰色的，適合駕駛員，能均勻阻絕各種顏色，顏色判斷較準確，不易失真；黃褐色，適合戶外運動，能過濾藍光，增強顏色對比敏感度；墨綠色，除了過濾紫外線，還能過濾紅外線。此外，選擇太陽鏡品牌產品更有質量保(bao)證(zheng)。
