Amalensi azacile futhi alula kunepulasitiki, amalensi e-polycarbonate (amelana nomthelela) anobufakazi bokonakala futhi ahlinzeka ngokuvikelwa kwe-UV okungu-100%, okuwenza abe yinketho efanelekile ezinganeni nakubantu abadala abakhuthele. Futhi ilungele imiyalelo eqinile njengoba ingangezi ukujiya lapho ilungisa ukubona, inciphisa noma yikuphi ukuhlanekezela.
Amalensi e-Photochromic amalensi aguquguqukayo azilungisela izimo zokukhanya ezahlukahlukene. Lapho usendlini,amalensi acacile futhi lapho echayeka elangeni, wonaphendukamnyama ngaphansi komzuzu.
Ubumnyama bombala oguqukayo wamalensi e-photochromic bunqunywa ubukhulu bokukhanya kwe-ultraviolet.
Ilensi ye-photochromic ingajwayela ukushintsha ukukhanya, ngakho-ke amehlo akho akumele enze lokhu. Ukugqoka lolu hlobo lwamalensiintandosiza amehlo akho akhululeke kancane.
Kunezigidigidi zama-molecule angabonakali ngaphakathi kwamalensi e-photochromic. Lapho ama-lens engabonakali ekukhanyeni kwe-ultraviolet, la ma-molecule agcina ukwakheka kwawo okujwayelekile futhi ama-lens ahlala esobala. Lapho bevezwa ekukhanyeni kwe-ultraviolet, isakhiwo samangqamuzana siqala ukushintsha isimo. Lokhu kusabela kubangela ukuthi amalensi abe nombala ofanayo. Lapho ama-lens esephumile ekukhanyeni kwelanga, ama-molecule abuyela esimweni sawo esivamile, futhi ama-lens aphinde akhanye.
Ziyakwazi ukuguqulwa kakhulu ezimweni ezihlukahlukene zokukhanya endaweni yasendlini nengaphandle
Banikeza induduzo enkulu, ngoba banciphisa i-eyestrain kanye ne-glare elangeni.
Ayatholakala emibhalweni eminingi.
Vikela amehlo emisebeni yelanga ye-UVA ne-UVB eyingozi (yehlisa ingozi yokuba nolwelwesi lwama-macular okuhlobene nobudala).
Zikuvumela ukuthi uyeke ukugxumagxuma phakathi kwezibuko zakho ezicacile nezibuko zakho.
Atholakala ngemibala eyahlukene ukuze afanele zonke izidingo.
