Ngokungafani nezibuko zelanga ezijwayelekile noma amalensi e-photochromic amane anciphise ukukhanya, amalensi e-UV400 ahlunga yonke imisebe yokukhanya enobude obungafika kuma-nanometer angu-400. Lokhu kufaka phakathi i-UVA, UVB kanye nokukhanya okuluhlaza okunamandla abonakalayo (HEV).
Ukuze kubhekwe njengezibuko ze-UV, amalensi kudingeka avimbe u-75% kuya ku-90% wokukhanya okubonakalayo futhi kufanele anikeze isivikelo se-UVA ne-UVB ukuvimba u-99% wemisebe ye-ultraviolet.
Ngokufanelekile, ufuna izibuko zelanga ezinikeza ukuvikeleka kwe-UV 400 njengoba zinikeza cishe ukuvikelwa okungu-100% emisebeni ye-UV.
Qaphela ukuthi akuzona zonke izibuko zelanga ezibhekwa njengezibuko ze-UV-protection. Ipheya lezibuko zelanga lingase libe namalensi amnyama, okungacatshangwa ukuthi avimba imisebe, kodwa lokho akusho ukuthi amathunzi ahlinzeka ngokuvikeleka okwanele kwe-UV.
Uma lezo zibuko ezinamalensi amnyama zingafaki ukuvikela kwe-UV, lezo zibuko ezimnyama empeleni zimbi emehlweni akho kunokungagqoki nhlobo izingubo zamehlo ezivikelayo. Kungani? Ngoba i-tint emnyama ingabangela abafundi bakho ukuthi banwebe, iveze amehlo akho ekukhanyeni okwengeziwe kwe-UV.
Ngingabona kanjani uma izibuko zami zinezivikelo ze-UV?
Ngeshwa, akulula ukusho ukuthi izibuko zakho zelanga noma amalensi e-photochromic anamalensi okuvikela e-UV ngokuwabuka nje.
Futhi awukwazi ukuhlukanisa inani lokuvikela ngokusekelwe kumbala welensi, njengoba ama-lens tints noma ubumnyama abuhlangene ngalutho nokuvikelwa kwe-UV.
Ukubheja kwakho okuhle ukuthatha izibuko zakho uye esitolo samehlo noma ezikhungweni zokuhlola ezingochwepheshe. Bangasebenzisa ukuhlolwa okulula ezingilazini zakho ukuze banqume izinga lokuvikelwa kwe-UV.
Noma ukukhetha okulula iwukugxilisa usesho lwakho kumkhiqizi onedumela elihle, nochwepheshe njengo-UNIVERSE OPTICAL, nokukhetha izibuko zelanga zangempela ze-UV400 noma amalensi e-photochromic e-UV400 ekhasini.https://www.universeoptical.com/1-56-aspherical-uv400-q-active-material-photochromic-lens-product/.
