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(su)料鏡(jing)(jing)(jing)片(pian)(pian)(pian)、玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian)、偏光鏡(jing)(jing)(jing)片(pian)(pian)(pian)、變色鏡(jing)(jing)(jing)片(pian)(pian)(pian)制作(zuo)。塑(su)料鏡(jing)(jing)(jing)片(pian)(pian)(pian)輕巧不(bu)易碎(sui),防紫(zi)外線功(gong)能優于(yu)玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian),耐磨(mo)性差(cha);玻(bo)璃鏡(jing)(jing)(jing)片(pian)(pian)(pian)其光學性能很穩(wen)定,不(bu)易變形(xing),但是易破碎(sui);偏光鏡(jing)(jing)(jing)片(pian)(pian)(pian)視線更清晰;變色鏡(jing)(jing)(jing)片(pian)(pian)(pian)可(ke)以根(gen)據光的強弱(ruo)自動調(diao)節。
二、太陽鏡和偏光鏡的區別
太(tai)陽(yang)鏡(jing)(jing)就是人們熟知(zhi)用于遮擋陽(yang)光(guang)(guang)(guang)和紫外線(xian)的有(you)(you)色眼鏡(jing)(jing),不(bu)能(neng)避免眩光(guang)(guang)(guang)對(dui)眼睛的傷(shang)害。 而偏(pian)光(guang)(guang)(guang)鏡(jing)(jing)能(neng)徹底濾除眩光(guang)(guang)(guang),達到對(dui)眼睛的真正保護。 太(tai)陽(yang)鏡(jing)(jing)只是利用減(jian)光(guang)(guang)(guang)的作(zuo)用,降(jiang)低了有(you)(you)害光(guang)(guang)(guang)線(xian)的強度,并沒有(you)(you)阻隔(ge)有(you)(you)害光(guang)(guang)(guang)線(xian)。偏(pian)光(guang)(guang)(guang)眼鏡(jing)(jing)可(ke)以完(wan)全阻隔(ge)散射、曲折(zhe)和反射等(deng)各種因(yin)素(su)造成的刺眼眩光(guang)(guang)(guang),即使長期(qi)從事(shi)強光(guang)(guang)(guang)活(huo)動,眼睛也(ye)可(ke)以得到保護。偏(pian)光(guang)(guang)(guang)鏡(jing)(jing)含有(you)(you)偏(pian)光(guang)(guang)(guang)夾片,能(neng)夠解決近視問題,而太(tai)陽(yang)鏡(jing)(jing)沒有(you)(you)此優勢。
三、太陽鏡的作用是什么
太陽(yang)(yang)鏡(jing),也稱遮陽(yang)(yang)鏡(jing),作遮陽(yang)(yang)之用(yong)。人(ren)(ren)在陽(yang)(yang)光(guang)(guang)下通(tong)常要靠調節(jie)(jie)瞳孔大小來調節(jie)(jie)光(guang)(guang)通(tong)量,當光(guang)(guang)線強度超過人(ren)(ren)眼(yan)(yan)調節(jie)(jie)能力(li),就會對人(ren)(ren)眼(yan)(yan)造成(cheng)(cheng)傷(shang)害(hai)。所以在戶外活動(dong)場所,特別(bie)是(shi)在夏天,需要采用(yong)遮陽(yang)(yang)鏡(jing)來遮擋陽(yang)(yang)光(guang)(guang),以減(jian)輕眼(yan)(yan)睛(jing)調節(jie)(jie)造成(cheng)(cheng)的(de)疲勞(lao)或強光(guang)(guang)刺激造成(cheng)(cheng)的(de)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質(zhi)量(liang)保證。
