Uv420 blue cut lensamalensi aklanywe ngokukhethekile akusiza ukuthi ugweme noma ubambezele ukuqala kwe-Age-Related Macular Degeneration (AMD) ngokumunca noma yikuphi ukusuka ku-10% kuya ngaphezu kuka-90% wokukhanya okuluhlaza okulimazayo okubonakala ngamandla aphezulu ebangeni lama-nanometer angu-380 kuya ku-495 nanometers. .uv420 blue cut lens Lokhu kuvimbela ukucindezelwa kwamehlo, kwenza isigqi se-circadian sijwayelekile futhi kwenza amehlo akhululeke kakhudlwana. Lawa ma-lens ayisixazululo esihle kakhulu kulabo abahlushwa iso ledijithali ngenxa yamahora amade okusebenza kumakhompyutha noma amadivaysi eselula.
Kuyinhlanganisela eyingqayizivele ye-anti-reflective coating kanye nesihlungi esiluhlaza okwesibhakabhaka, esikuvikela emiphumeleni eyingozi yokukhanya kwe-High Energy Visible (HEV) ekhishwa izikrini ze-electronic ezifana namathebulethi, ama-smartphone, amakhompyutha nama-TV.Uv420 blue cut lensLokhu kunamathela okukhethekile kuvimbela ukudluliswa kokukhanya okuluhlaza okulimazayo, kuyilapho kuvumela ingxenye enhle yokukhanya okuluhlaza okuzuzisayo okunesibopho sokukhiqizwa kwe-melatonin, ihomoni yokulala. Ngaphezu kwalokho, lawa ma-lens awaphazamisi ukubona umbala wemvelo.
I-pigment enciphisa ukukhanya eluhlaza okwesibhakabhaka empeleni yengezwa kumalensi ngaphambi kwenqubo yokuphonsa futhi ayiyona nje i-tint noma ukunamathela, okwenza amalensi aphumelele kakhulu ekuvimbeni lokhu kukhanya okulimazayo kunezibuko ezivamile eziphikisana nokuxhopha. Lawa ma-lens aphinde acace ngendlela emangalisayo ngaphandle kokuhlanekezelwa kombala, okuwenza alungele ukusetshenziswa kwansuku zonke.
Lawa ma-lens ayatholakala futhi kuhlu olubanzi lwemiyalelo, kusukela kumalensi okubuka okukodwa kuya kumalensi e-bifocal kanye naqhubekayo futhi angenziwa ngokwezifiso nganoma iyiphi idizayini yohlaka oluthandayo. Zingenziwa futhi njengezibuko zelanga ezingenalutho, ezinemibala noma ezicacile. Lawa ma-lens anconyelwe labo abachitha isikhathi eside besendlini besebenzisa izinto zikagesi noma emgwaqweni, njengabashayeli nabagibeli bamabhayisikili abasebenza ekuseni kakhulu (ukukhanya okuphansi) nasemini kakhulu lapho kukhanya ngaphandle.
Ucwaningo luye lwabonisa ukuthi ukuchayeka okuqhubekayo ekukhanyeni kwe-HEV okuvela kumadivayisi edijithali, ikakhulukazi i-Blue Light ewela ngaphakathi kwebhendi ye-415nm-455nm ye-spectrum, kungaholela ezinkingeni zezempilo ezihlukahlukene ezifana namehlo omile nokungaboni kahle, ukwanda kwengozi yokuwohloka kwe-macular. , ukungalali kahle, ikhanda elibuhlungu nokuqwasha. Ezinganeni, kungenzeka futhi ukuthi lezi zimpawu zingase zibe nomthelela ekwenyukeni kwe-myopia (ukubona eduze) okubonwe kusukela umqedazwe we-COVID-19. Kodwa-ke, ucwaningo olwengeziwe luyadingeka kule ndawo ukuze kutholwe ukuthi ukusetshenziswa kwamalensi aluhlaza okwesibhakabhaka kubantu abasha kungaba nemiphumela engahlosiwe ekuthuthukisweni kobude be-ocular axial ngokushintsha kwe-Purkinje rod-cone. Lena inqubo yebhayoloji eyinkimbinkimbi okwamanje ingaphansi kophenyo olunzulu.
