一、太陽鏡鏡片什么材質的好

太(tai)陽鏡(jing)(jing)(jing)鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)一般(ban)采用塑料鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)、玻(bo)璃(li)鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)、偏光鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)、變色鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)制(zhi)作。塑料鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)輕巧不易(yi)碎，防(fang)紫外線(xian)功能(neng)優于玻(bo)璃(li)鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)，耐磨性(xing)差(cha)；玻(bo)璃(li)鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)其光學性(xing)能(neng)很穩定，不易(yi)變形，但是(shi)易(yi)破碎；偏光鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)視線(xian)更清晰；變色鏡(jing)(jing)(jing)片(pian)(pian)(pian)(pian)(pian)可(ke)以根據光的強弱自動(dong)調節。

二、太陽鏡和偏光鏡的區別

太陽(yang)鏡(jing)就是人們熟知用(yong)于遮擋陽(yang)光(guang)(guang)(guang)和(he)紫外(wai)線(xian)的(de)有(you)色眼(yan)鏡(jing)，不能避免(mian)眩(xuan)光(guang)(guang)(guang)對眼(yan)睛的(de)傷害(hai)。 而偏(pian)光(guang)(guang)(guang)鏡(jing)能徹底濾除眩(xuan)光(guang)(guang)(guang)，達到(dao)對眼(yan)睛的(de)真正(zheng)保護(hu)。 太陽(yang)鏡(jing)只(zhi)是利用(yong)減光(guang)(guang)(guang)的(de)作用(yong)，降低了有(you)害(hai)光(guang)(guang)(guang)線(xian)的(de)強(qiang)度，并沒(mei)有(you)阻隔(ge)有(you)害(hai)光(guang)(guang)(guang)線(xian)。偏(pian)光(guang)(guang)(guang)眼(yan)鏡(jing)可(ke)以完全阻隔(ge)散射、曲折和(he)反射等各種(zhong)因素造(zao)成的(de)刺眼(yan)眩(xuan)光(guang)(guang)(guang)，即使長(chang)期從事(shi)強(qiang)光(guang)(guang)(guang)活動，眼(yan)睛也(ye)可(ke)以得到(dao)保護(hu)。偏(pian)光(guang)(guang)(guang)鏡(jing)含有(you)偏(pian)光(guang)(guang)(guang)夾片，能夠解決近視問(wen)題，而太陽(yang)鏡(jing)沒(mei)有(you)此(ci)優(you)勢。

三、太陽鏡的作用是什么

太陽(yang)鏡，也稱遮陽(yang)鏡，作遮陽(yang)之用(yong)。人(ren)在陽(yang)光(guang)下通常要(yao)靠調(diao)節(jie)瞳孔大小來調(diao)節(jie)光(guang)通量，當光(guang)線強度超過人(ren)眼調(diao)節(jie)能力，就會對(dui)人(ren)眼造(zao)成(cheng)傷害(hai)。所以在戶(hu)外活動場所，特別是在夏(xia)天(tian)，需要(yao)采用(yong)遮陽(yang)鏡來遮擋(dang)陽(yang)光(guang)，以減輕眼睛調(diao)節(jie)造(zao)成(cheng)的疲勞或強光(guang)刺(ci)激造(zao)成(cheng)的傷害(hai)。

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證(zheng)。
