I-Polycarbonate Semi Egqityiweyo I-Spin Coat I-Photochromic Lens Blanks
Kutheni iiLensi zePolycarbonate?
Xa kuziwa kukhuseleko lwamehlo, iilensi ze-polycarbonate kunye ne-Trivex kufuneka zibe zezokuqala ozikhethayo.Azizincinci kwaye zikhaphukhaphu kuphela kunezinye izixhobo zelensi, kodwa ziyakwazi ukumelana nempembelelo ngamaxesha ali-10 kuneeplastiki eziqhelekileyo okanye iilensi zeglasi.Bakwabonelela ngokhuseleko lwe-100% kwimitha ye-UV.
Ezi mpawu zingundoqo xa ucinga ngokuthenga ezemidlalo okanye iimpahla zamehlo zabantwana kodwa zifanelekile kuzo zonke iilensi zeglasi.Zombini iilensi ze-polycarbonate kunye ne-Trivex zikhuselekile kwaye zilungele ukhetho ngalunye, kodwa ziyahluka kwezinye iindawo, zibonelela ngamava okukhanya ahlukeneyo.
Ziziphi iilensi zephotochromic?
Iilensi zePhotochromic ziilensi eziguquguqukayo ezizilungelelanisa ngokwazo kwiimeko ezahlukeneyo zokukhanya.Xa ungaphakathi endlwini, iilensi zicacile kwaye xa zibekwe elangeni, zijika zibe mnyama ngaphantsi komzuzu.
Ukutshintsha kombala okrelekrele
Ubumnyama bombala emva kokutshintsha kweelensi ze-photochromic zigqitywe ngamandla okukhanya kwe-ultraviolet.
I-photochromic lens inokuqhelana nokutshintsha ukukhanya, ngoko amehlo akho akufuneki enze oku.Ukunxiba olu hlobo lwelensi kuya kunceda amehlo akho aphumle kancinci.
Kutheni iilensi zepolycarbonate?
Ibhityile kwaye ikhaphukhaphu kuneplastiki, iilensi ze-polycarbonate (i-impact-resistant) zinobungqina bokuqhekeza kwaye zibonelela ngokhuseleko lwe-UV oluyi-100%, nto leyo ebenza babe lolona khetho lufanelekileyo kubantwana nakubantu abadala abasebenzayo.Zikwayilungele imimiselo eyomeleleyo kuba abongezi ubungqingqwa xa belungisa umbono, ukunciphisa nakuphi na ukugqwetheka.
Yintoni ilensi yasimahla?
Ilensi ekhululekileyo iqhele ukuba nomphezulu ongqukuva wangaphambili kunye nomphezulu ontsonkothileyo, onamacala amathathu ngasemva oquka ummiselo wesigulana.Kwimeko ye-lens eqhubekayo ye-freeform, i-geometry yendawo yangasemva ibandakanya uyilo oluqhubekayo.
Inkqubo ye-freeform isebenzisa iilensi ezingqukuva ezinesiqingatha ezigqityiweyo ezifumaneka lula kuluhlu olubanzi lweegophe ezisisiseko kunye nezalathisi.Ezi lens zenziwa ngokuchanekileyo kwicala elingasemva kusetyenziswa izixhobo zanamhlanje zokuvelisa kunye nokupolisha ukwenza umphezulu ochanekileyo.
• Umphezulu ongaphambili ngumphezulu olula ongqukuva
• umphezulu ongemva ngumhlaba ontsonkothileyo onamacala amathathu
Itekhnoloji yeelensi zasimahla
• Ibonelela ngokuguquguquka ukubonelela ngoluhlu olubanzi lweemveliso ezikwinqanaba eliphezulu, nakwilabhoratri yamehlo encinci.
• Ifuna kuphela isitokhwe see-semi-finished spheres kwimathiriyeli nganye kuwo nawuphi na umthombo womgangatho
• Ulawulo lweLab lwenziwa lula ngee-SKU ezimbalwa kakhulu
• Umphezulu oqhubela phambili usondele kwiliso - ubonelela ngemimandla ebanzi yokujonga kwipaseji nakwindawo yokufunda
• Ukuvelisa ngokuchanekileyo uyilo oluqhubela phambili olucetywayo
• Ukuchaneka kwamayeza akuthintelwa ngamanyathelo ezixhobo akhoyo elabhoratri
• Ulungelelwaniso oluchanekileyo lwamayeza luqinisekisiwe
