一、太陽鏡鏡片什么材質的好
太陽鏡(jing)(jing)(jing)(jing)鏡(jing)(jing)(jing)(jing)片(pian)(pian)一般采用塑料鏡(jing)(jing)(jing)(jing)片(pian)(pian)、玻(bo)(bo)璃鏡(jing)(jing)(jing)(jing)片(pian)(pian)、偏光鏡(jing)(jing)(jing)(jing)片(pian)(pian)、變(bian)(bian)色鏡(jing)(jing)(jing)(jing)片(pian)(pian)制作(zuo)。塑料鏡(jing)(jing)(jing)(jing)片(pian)(pian)輕巧(qiao)不易(yi)碎(sui),防紫外線(xian)功(gong)能(neng)優(you)于(yu)玻(bo)(bo)璃鏡(jing)(jing)(jing)(jing)片(pian)(pian),耐磨性差;玻(bo)(bo)璃鏡(jing)(jing)(jing)(jing)片(pian)(pian)其(qi)光學性能(neng)很(hen)穩定,不易(yi)變(bian)(bian)形,但是易(yi)破(po)碎(sui);偏光鏡(jing)(jing)(jing)(jing)片(pian)(pian)視線(xian)更清晰;變(bian)(bian)色鏡(jing)(jing)(jing)(jing)片(pian)(pian)可以根據光的強弱自動調節。
二、太陽鏡和偏光鏡的區別
太陽(yang)鏡就是人(ren)們熟知(zhi)用(yong)于(yu)遮擋陽(yang)光(guang)(guang)(guang)和(he)紫(zi)外線(xian)的有(you)(you)(you)色(se)眼(yan)(yan)鏡,不能(neng)避免(mian)眩光(guang)(guang)(guang)對眼(yan)(yan)睛的傷害。 而偏(pian)光(guang)(guang)(guang)鏡能(neng)徹底濾除(chu)眩光(guang)(guang)(guang),達(da)到對眼(yan)(yan)睛的真(zhen)正保(bao)護(hu)。 太陽(yang)鏡只是利用(yong)減光(guang)(guang)(guang)的作用(yong),降低了有(you)(you)(you)害光(guang)(guang)(guang)線(xian)的強度,并沒有(you)(you)(you)阻隔有(you)(you)(you)害光(guang)(guang)(guang)線(xian)。偏(pian)光(guang)(guang)(guang)眼(yan)(yan)鏡可(ke)以(yi)完全阻隔散射、曲折(zhe)和(he)反(fan)射等各種因素(su)造成的刺眼(yan)(yan)眩光(guang)(guang)(guang),即使長期從(cong)事強光(guang)(guang)(guang)活動,眼(yan)(yan)睛也(ye)可(ke)以(yi)得(de)到保(bao)護(hu)。偏(pian)光(guang)(guang)(guang)鏡含有(you)(you)(you)偏(pian)光(guang)(guang)(guang)夾片,能(neng)夠解決(jue)近視(shi)問題,而太陽(yang)鏡沒有(you)(you)(you)此(ci)優(you)勢。
三、太陽鏡的作用是什么
太(tai)陽(yang)鏡,也稱遮(zhe)陽(yang)鏡,作遮(zhe)陽(yang)之用(yong)。人在(zai)陽(yang)光下通常要靠(kao)調(diao)節(jie)瞳孔大小來調(diao)節(jie)光通量,當光線強度超過人眼(yan)調(diao)節(jie)能(neng)力,就會(hui)對人眼(yan)造(zao)成(cheng)傷害。所(suo)以在(zai)戶外活動(dong)場(chang)所(suo),特別是在(zai)夏天,需要采用(yong)遮(zhe)陽(yang)鏡來遮(zhe)擋陽(yang)光,以減輕眼(yan)睛(jing)調(diao)節(jie)造(zao)成(cheng)的(de)疲(pi)勞或(huo)強光刺(ci)激(ji)造(zao)成(cheng)的(de)傷害。
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。
