一、太陽鏡鏡片什么材質的好
太(tai)陽鏡(jing)(jing)鏡(jing)(jing)片(pian)(pian)一般采用(yong)塑料鏡(jing)(jing)片(pian)(pian)、玻(bo)璃(li)鏡(jing)(jing)片(pian)(pian)、偏光(guang)(guang)鏡(jing)(jing)片(pian)(pian)、變色鏡(jing)(jing)片(pian)(pian)制作。塑料鏡(jing)(jing)片(pian)(pian)輕(qing)巧不易碎(sui)(sui),防(fang)紫外線功能(neng)優于玻(bo)璃(li)鏡(jing)(jing)片(pian)(pian),耐磨性(xing)(xing)差;玻(bo)璃(li)鏡(jing)(jing)片(pian)(pian)其光(guang)(guang)學性(xing)(xing)能(neng)很穩定,不易變形,但是易破碎(sui)(sui);偏光(guang)(guang)鏡(jing)(jing)片(pian)(pian)視(shi)線更清(qing)晰;變色鏡(jing)(jing)片(pian)(pian)可以根據光(guang)(guang)的(de)強(qiang)弱自動(dong)調節。
二、太陽鏡和偏光鏡的區別
太(tai)陽(yang)(yang)鏡(jing)(jing)(jing)就(jiu)是(shi)人們熟知(zhi)用于遮擋陽(yang)(yang)光(guang)(guang)(guang)和紫外線的有(you)(you)(you)色眼鏡(jing)(jing)(jing),不能(neng)避(bi)免眩(xuan)光(guang)(guang)(guang)對眼睛的傷害(hai)。 而偏(pian)(pian)光(guang)(guang)(guang)鏡(jing)(jing)(jing)能(neng)徹底濾除眩(xuan)光(guang)(guang)(guang),達到對眼睛的真正(zheng)保(bao)護。 太(tai)陽(yang)(yang)鏡(jing)(jing)(jing)只是(shi)利用減光(guang)(guang)(guang)的作用,降(jiang)低了有(you)(you)(you)害(hai)光(guang)(guang)(guang)線的強(qiang)度,并沒有(you)(you)(you)阻隔有(you)(you)(you)害(hai)光(guang)(guang)(guang)線。偏(pian)(pian)光(guang)(guang)(guang)眼鏡(jing)(jing)(jing)可以完全阻隔散射、曲折和反射等各(ge)種因素造(zao)成的刺眼眩(xuan)光(guang)(guang)(guang),即使長期從(cong)事強(qiang)光(guang)(guang)(guang)活動,眼睛也可以得到保(bao)護。偏(pian)(pian)光(guang)(guang)(guang)鏡(jing)(jing)(jing)含有(you)(you)(you)偏(pian)(pian)光(guang)(guang)(guang)夾片,能(neng)夠解決近視問題,而太(tai)陽(yang)(yang)鏡(jing)(jing)(jing)沒有(you)(you)(you)此(ci)優勢。
三、太陽鏡的作用是什么
太陽(yang)鏡(jing),也稱遮(zhe)陽(yang)鏡(jing),作遮(zhe)陽(yang)之用。人(ren)在陽(yang)光下通常要(yao)(yao)靠調節(jie)瞳孔大小(xiao)來(lai)調節(jie)光通量,當光線(xian)強度(du)超過(guo)人(ren)眼調節(jie)能力,就會對人(ren)眼造成(cheng)傷(shang)害(hai)。所(suo)以在戶外活動場所(suo),特別是(shi)在夏天,需(xu)要(yao)(yao)采用遮(zhe)陽(yang)鏡(jing)來(lai)遮(zhe)擋陽(yang)光,以減輕眼睛調節(jie)造成(cheng)的疲勞(lao)或強光刺激(ji)造成(cheng)的傷(shang)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(you)質量保證。
