一、太陽鏡鏡片什么材質的好
太陽(yang)鏡(jing)(jing)鏡(jing)(jing)片(pian)(pian)一般采(cai)用塑(su)料鏡(jing)(jing)片(pian)(pian)、玻(bo)璃鏡(jing)(jing)片(pian)(pian)、偏光鏡(jing)(jing)片(pian)(pian)、變色(se)鏡(jing)(jing)片(pian)(pian)制作。塑(su)料鏡(jing)(jing)片(pian)(pian)輕巧不(bu)易碎,防紫外線功能(neng)優于(yu)玻(bo)璃鏡(jing)(jing)片(pian)(pian),耐磨性差;玻(bo)璃鏡(jing)(jing)片(pian)(pian)其光學性能(neng)很穩定,不(bu)易變形,但是易破碎;偏光鏡(jing)(jing)片(pian)(pian)視線更清(qing)晰;變色(se)鏡(jing)(jing)片(pian)(pian)可(ke)以根(gen)據光的(de)強弱自(zi)動調節。
二、太陽鏡和偏光鏡的區別
太(tai)(tai)陽(yang)鏡(jing)(jing)就(jiu)是人們熟知用于遮擋陽(yang)光(guang)(guang)(guang)(guang)(guang)和紫外線(xian)的(de)有色眼(yan)鏡(jing)(jing),不能避免眩光(guang)(guang)(guang)(guang)(guang)對(dui)眼(yan)睛的(de)傷害。 而偏(pian)光(guang)(guang)(guang)(guang)(guang)鏡(jing)(jing)能徹(che)底濾除眩光(guang)(guang)(guang)(guang)(guang),達(da)到對(dui)眼(yan)睛的(de)真正保護。 太(tai)(tai)陽(yang)鏡(jing)(jing)只是利(li)用減光(guang)(guang)(guang)(guang)(guang)的(de)作用,降低了有害光(guang)(guang)(guang)(guang)(guang)線(xian)的(de)強度,并沒(mei)有阻隔(ge)有害光(guang)(guang)(guang)(guang)(guang)線(xian)。偏(pian)光(guang)(guang)(guang)(guang)(guang)眼(yan)鏡(jing)(jing)可以(yi)完全(quan)阻隔(ge)散射、曲(qu)折和反射等各種(zhong)因素(su)造成的(de)刺眼(yan)眩光(guang)(guang)(guang)(guang)(guang),即(ji)使長期(qi)從事強光(guang)(guang)(guang)(guang)(guang)活動,眼(yan)睛也(ye)可以(yi)得到保護。偏(pian)光(guang)(guang)(guang)(guang)(guang)鏡(jing)(jing)含(han)有偏(pian)光(guang)(guang)(guang)(guang)(guang)夾片,能夠(gou)解決近視問題(ti),而太(tai)(tai)陽(yang)鏡(jing)(jing)沒(mei)有此(ci)優(you)勢。
三、太陽鏡的作用是什么
太陽(yang)鏡(jing),也(ye)稱(cheng)遮(zhe)陽(yang)鏡(jing),作遮(zhe)陽(yang)之用(yong)。人(ren)在(zai)陽(yang)光(guang)(guang)下通(tong)常要(yao)靠(kao)調(diao)節(jie)瞳(tong)孔(kong)大小來(lai)調(diao)節(jie)光(guang)(guang)通(tong)量,當光(guang)(guang)線強度超過人(ren)眼調(diao)節(jie)能力(li),就會(hui)對人(ren)眼造成傷害(hai)。所(suo)以在(zai)戶外活動場所(suo),特別是在(zai)夏天,需要(yao)采(cai)用(yong)遮(zhe)陽(yang)鏡(jing)來(lai)遮(zhe)擋(dang)陽(yang)光(guang)(guang),以減輕眼睛(jing)調(diao)節(jie)造成的疲勞或強光(guang)(guang)刺激造成的傷害(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(chan)品更有質量保證。
