Magirazi ezuvaneUV dziviriro imhaka yekuwedzera kwejasi rakakosha pamalenzi, uye magirazi ezuva epasi haangogone chete kuvhara mwenje weUV, asi zvakare anoderedza zvakanyanya kutapurirana kwemalenzi, zvichiita kuti vadzidzi vakure, uye ultraviolet mwaranzi inobaiwa muhuwandu hukuru. , zvichikonzera kukanganisa maziso..Saka nhasi,IVisionOptical ichakutora iwe kuti unzwisise: sei kuziva kana magirazi ezuva ari kudzivirira UV-resistant?
Nzira 1. Tarisa pane chinyorwa chemagirazi ezuva.
Zviratidzo zvinooneka zvakaita se "UV dziviriro", "UV400", nezvimwewo zvinoonekwa pamavara kana malenses eUV-resistant.magirazi ezuva."UV index" ndiwo mhedzisiro yekusefa kunze kwemwaranzi yeultraviolet, inova mucherechedzo wakakosha wekutenga magirazi ezuva.Chiedza chine wavelength ye286nm-400nm chinonzi ultraviolet light.Kazhinji, 100% UV index haigoneki.Iyo UV index yemagirazi mazhinji ari pakati pe96% ne98%.
Magirazi ezuva ane anti-ultraviolet basa anowanzo ane nzira dzinotevera dzinoratidza:
a) Maka "UV400": izvi zvinoreva kuti kuchekwa kwewavelength yelenzi kune ultraviolet mwenje i400nm, kureva kuti, kukosha kwepamusoro τmax (λ) kweiyo spectral transmittance pawavelength (λ) pazasi 400nm haina kupfuura. 2%;
b) Maka "UV" uye "UV dziviriro": izvi zvinoreva kuti kuchekwa-kubvisa wavelength yelenzi kune ultraviolet i380nm, ndiko kuti, kukosha kwepamusoro τmax(λ) kweiyo spectral transmittance pawavelength (λ) pazasi 380nm. haisi kupfuura 2%;
c) Maka "100% UV absorption": Izvi zvinoreva kuti lenzi ine basa re100% kunyura kwemwaranzi yeultraviolet, ndiko kuti, avhareji yekutapurirana kwayo muultraviolet renji haina kudarika 0.5%.
Magirazi ezuva anosangana nezvinodiwa pamusoro apa ndiwo magirazi anodzivirira kubva kune ultraviolet mwaranzi mupfungwa yechokwadi.
Nzira 2. Shandisa chinyoreso chebhengi kuti utarise chokwadi
Mukushaikwa kwezviridzwa, vanhuwo zvavo vanogona kuona kana magirazi ezuva ane UV dziviriro.Tora pepa remari, isa lenzi yezuva pane anti-counterfeiting watermark, uye tora pikicha palenzi nejena remari kana chidhina chemari.Kana iwe uchiri kuona iyo watermark, zvinoreva kuti magirazi haadzivirirwe neUV.Kana iwe usingazvione, zvinoreva kuti Magirazi ezuva akachengetedzwa neUV.
Kupfupisa zviri pamusoro: Nzira 2 ndeyekusimbisa iyomagirazi ezuvalabel in Method 1. Zvinogona kuoneka zvishoma kana zita remutengesi rakarurama uye kana magirazi ezuva ane basa reanti-ultraviolet.Paunenge uchitenga magirazi ezuva, unogona kuzviedza.Muchiito chekutenga nekupfeka, kana uine chero mibvunzo, ndapota tarisa kune rumwe ruzivo rwakakodzera.
