Ngokungafani nezibuko zelanga ezivamile noma amalensi e-photochromic anciphisa ukukhanya nje, amalensi e-UV400 ahlunga yonke imisebe yokukhanya enama-wavelength afinyelela kuma-nanometer angu-400. Lokhu kufaka phakathi i-UVA, i-UVB kanye nokukhanya okuluhlaza okwesibhakabhaka okubonakalayo okunamandla aphezulu (HEV).
Ukuze kubhekwe njengezibuko ze-UV, amalensi kudingeka ukuthi avimbele ukukhanya okubonakalayo okungu-75% kuya ku-90% futhi kumele ahlinzeke ngokuvikelwa kwe-UVA kanye ne-UVB ukuvimba imisebe ye-ultraviolet engu-99%.
Kungcono kakhulu, ufuna izibuko zelanga ezinikeza isivikelo se-UV 400 ngoba zinikeza isivikelo esicishe sibe yi-100% emisebeni ye-UV.
Qaphela ukuthi akuzona zonke izibuko zelanga ezibhekwa njengezibuko zelanga ezivikela i-UV. Izibuko zelanga ezimbili zingaba namalensi amnyama, okungacatshangwa ukuthi avimba imisebe, kodwa lokho akusho ukuthi imibala inikeza isivikelo esanele se-UV.
Uma lezo zibuko zelanga ezinamalensi amnyama zingafaki ukuvikelwa kwe-UV, lezo zithunzi ezimnyama empeleni zimbi kakhulu emehlweni akho kunokungagqoki nhlobo izibuko zamehlo ezivikelayo. Kungani? Ngoba umbala omnyama ungabangela ukuthi amehlo akho avuleke, okuveza amehlo akho ekukhanyeni kwe-UV okwengeziwe.
Ngingazi kanjani ukuthi izibuko zami zinesivikelo se-UV?
Ngeshwa, akulula ukubona ukuthi izibuko zakho zelanga noma amalensi e-photochromic anamalensi okuvikela i-UV ngokuwabuka nje.
Futhi awukwazi ukuhlukanisa inani lokuvikelwa ngokusekelwe kumbala welensi, njengoba imibala yelensi noma ubumnyama kungahlobene nokuvikelwa kwe-UV.
Okungcono kakhulu ukuthi uthathe izibuko zakho uziyise esitolo sezinto ezibonakalayo noma ezikhungweni zokuhlola zobungcweti. Bangenza isivivinyo esilula ezibukweni zakho ukuze bathole izinga lokuvikelwa kwe-UV.
Noma ukukhetha okulula ukugxilisa usesho lwakho kumkhiqizi odumile, nochwepheshe njenge-UNIVERSE OPTICAL, bese ukhetha izibuko zelanga zangempela ze-UV400 noma amalensi e-UV400 photochromic ekhasini.https://www.universeoptical.com/1-56-aspherical-uv400-q-active-material-photochromic-lens-product/.
