Ese magirazi ezuva ane 100% UV anodzivirira
Ngatitangei kunzwisisa ultraviolet chiedza.Urefu hwechiedza che ultraviolet huri pasi pe400 uv.Mushure mokunge ziso raonekwa, richakuvadza cornea uye retina, zvichiita kuti solar keratitis uye corneal endothelial damage.Magirazi epamusoro-soro anofanirwa kukwanisa kutora kana kuratidza ultraviolet rays kudzivirira kuonekwa kwemaziso.
Magirazi ezuva ane anti-ultraviolet basa anowanzo ane nzira dzakati wandei dzakajeka:
1. Maka “UV400″:
Zvinoreva kuti kuparadzaniswa kwewavelength yelenzi kune ultraviolet mwaranzi ndeye 400nm, ndiko kuti, kukosha kwepamusoro kweiyo spectral transmittance pawavelength iri pasi pe400nm haigone kuva yakakura kupfuura 2%.
2. Maka “UV”, “UV dziviriro”:
Inoratidza kuti kuvharika kwewavelength yelenzi kurwisa ultraviolet mwaranzi ndeye 380nm.
3. Maka "100% UV absorption":
Zvinoreva kuti lenzi ine 100% kunyura kwemwaranzi ye ultraviolet, kureva kuti, avhareji yekutapurira mu ultraviolet range haisi kupfuura 0.5%. basa rekudzivirira kubva kune ultraviolet mwaranzi mupfungwa yechokwadi.

Magirazi ezuva ari nani pane akajairwa magirazi ezuva
Iwo anonzi magirazi ezuva, mukuwedzera kumabasa emagirazi ezuva, anogona zvakare kunetesa uye kuvharira kushata.
inotaridza mwenje, kupenya, kuratidzwa kusingaenzaniswi kwezvinhu, nezvimwe, uye kupfuudza axis yekufambisa kweiyo track chaiyo
ziso rekuona uye kuita chiono chakapfuma Ma Level, chiono chakajeka uye chinowedzera zvisikwa.Polarizers kazhinji
akakodzera mabasa ekunze akadai sekutyaira, kubata hove, kufamba nechikepe, whitewater rafting, uye skiing.Semuvara we
polarizer lenses anowanzo kusviba, hazvifanirwe kuapfeka mumazuva ane makore kana mukati.Unofanira kusarudza
mamwe magirazi ezuva ekudzivirira maziso ako kubva kune ultraviolet mwaranzi.
