一、太陽鏡鏡片什么材質的好
太陽鏡(jing)(jing)(jing)鏡(jing)(jing)(jing)片(pian)(pian)(pian)一般采用塑料鏡(jing)(jing)(jing)片(pian)(pian)(pian)、玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian)、偏光(guang)(guang)鏡(jing)(jing)(jing)片(pian)(pian)(pian)、變(bian)(bian)色(se)(se)鏡(jing)(jing)(jing)片(pian)(pian)(pian)制作。塑料鏡(jing)(jing)(jing)片(pian)(pian)(pian)輕巧不(bu)易碎,防(fang)紫外線功能優于玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian),耐(nai)磨(mo)性(xing)差;玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian)其光(guang)(guang)學(xue)性(xing)能很穩定,不(bu)易變(bian)(bian)形,但是(shi)易破碎;偏光(guang)(guang)鏡(jing)(jing)(jing)片(pian)(pian)(pian)視線更清晰;變(bian)(bian)色(se)(se)鏡(jing)(jing)(jing)片(pian)(pian)(pian)可以(yi)根據光(guang)(guang)的強弱自動調節(jie)。
二、太陽鏡和偏光鏡的區別
太陽(yang)鏡(jing)就是人們熟知用于遮擋陽(yang)光(guang)(guang)(guang)和紫外(wai)線的有(you)色眼(yan)(yan)鏡(jing),不能避免(mian)眩光(guang)(guang)(guang)對(dui)眼(yan)(yan)睛的傷害。 而(er)偏(pian)光(guang)(guang)(guang)鏡(jing)能徹(che)底濾除眩光(guang)(guang)(guang),達到對(dui)眼(yan)(yan)睛的真正保護。 太陽(yang)鏡(jing)只是利用減光(guang)(guang)(guang)的作用,降(jiang)低了有(you)害光(guang)(guang)(guang)線的強(qiang)度,并沒(mei)有(you)阻(zu)隔有(you)害光(guang)(guang)(guang)線。偏(pian)光(guang)(guang)(guang)眼(yan)(yan)鏡(jing)可以(yi)完全阻(zu)隔散射、曲(qu)折和反射等各(ge)種因(yin)素造成的刺(ci)眼(yan)(yan)眩光(guang)(guang)(guang),即使長期從(cong)事強(qiang)光(guang)(guang)(guang)活(huo)動,眼(yan)(yan)睛也可以(yi)得到保護。偏(pian)光(guang)(guang)(guang)鏡(jing)含(han)有(you)偏(pian)光(guang)(guang)(guang)夾片,能夠解決近視問題,而(er)太陽(yang)鏡(jing)沒(mei)有(you)此優勢。
三、太陽鏡的作用是什么
太陽(yang)鏡,也稱遮(zhe)陽(yang)鏡,作(zuo)遮(zhe)陽(yang)之(zhi)用。人(ren)在陽(yang)光(guang)下通(tong)常要靠調(diao)節(jie)瞳孔大(da)小來調(diao)節(jie)光(guang)通(tong)量,當光(guang)線(xian)強(qiang)度超(chao)過人(ren)眼調(diao)節(jie)能力,就會對人(ren)眼造(zao)成(cheng)傷害(hai)。所以在戶外活動(dong)場所,特別是(shi)在夏天,需要采(cai)用遮(zhe)陽(yang)鏡來遮(zhe)擋(dang)陽(yang)光(guang),以減輕(qing)眼睛調(diao)節(jie)造(zao)成(cheng)的疲(pi)勞或強(qiang)光(guang)刺激造(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(pin)更(geng)有質量(liang)保證。
