uv420 blue cut lensIilensi ezilungiselelwe ngokukodwa ezikunceda ukuphepha okanye ukulibazisa ukuqala kwe-Age-Related Macular Degeneration (AMD) ngokufunxa naphi na ukusuka kwi-10% ukuya ngaphezulu kwe-90% yokukhanya okuluhlaza okuyingozi okubonakalayo ngamandla aphezulu kuluhlu lwe-380 nanometers ukuya kwi-495 nanometers. .uv420 blue cut lens Oku kuthintela ubunzima bamehlo, iqhelekile isingqisho se-circadian kwaye yenza amehlo akhululeke ngakumbi. Ezi lens zikwasisisombululo esihle kwabo banengxaki yamehlo edijithali ngenxa yeeyure ezinde zokusebenza kwiikhompyuter okanye kwizixhobo eziphathwayo.
Kukudityaniswa okukhethekileyo kokutyatyekwa okuchasene ne-reflective kunye nesihluzi esiluhlaza, esikukhusela kwiziphumo ezinobungozi zokukhanya kwe-High Energy Visible (HEV) ezikhutshwa zizikrini ze-elektroniki ezifana neetafile, ii-smartphones, iikhompyutha kunye nee-TV.uv420 blue cut lensOlu tyaba lukhethekileyo luthintela ukuhanjiswa kokukhanya okuluhlaza okuyingozi, ngelixa lusavumela isahlulo esihle sokukhanya okuluhlaza okunenzuzo onoxanduva lokuvelisa i-melatonin, ihomoni yokulala. Ukongezelela, ezi lens aziphazamisi ukubona umbala wendalo.
Ibala eliluhlaza okwesibhakabhaka elinciphisa ukukhanya kongezwe kwiilensi phambi kwenkqubo yokuphosa kwaye ayisiyiyo i-tint okanye i-coating nje, nto leyo eyenza iilensi zisebenze ngakumbi ekuthinteleni oku kukhanya konakalisayo kuneeglasi eziqhelekileyo zokunqanda ukukhazimla. Ezi lens zikwacace ngendlela engakholelekiyo ngaphandle kokugqwethwa kombala, zizenza zilungele ukusetyenziswa kwemihla ngemihla.
Ezi lens zikwafumaneka kuluhlu olubanzi lwemimiselo, ukusuka kumbono omnye ukuya kwi-bifocal kunye ne-progressive lens kwaye inokwenziwa ngokwezifiso kunye naluphi na uyilo lwesakhelo oyithandayo. Zisenokwenziwa njengeeglasi zelanga ezingenamrim, ezinemibala okanye ezicacileyo. Ezi lens zicetyiswa kwabo bachitha ixesha elide bengaphakathi ezindlwini besebenzisa izixhobo zombane okanye endleleni, njengabaqhubi nabakhweli beebhayisikile abasebenza kusasa kakhulu (ukukhanya okuphantsi) nasemva kwemini xa kuqaqambile ngaphandle.
Uphononongo lubonise ukuba ukuvezwa okuqhubekayo ekukhanyeni kwe-HEV ukusuka kwizixhobo zedijithali, ngakumbi i-Blue Light ewela ngaphakathi kwe-415nm-455nm band ye-spectrum, inokukhokelela kwiingxaki ezahlukeneyo zempilo ezifana namehlo omileyo kunye nombono ophazamisayo, ukwanda komngcipheko we-macular degeneration. , ukungalali kakuhle, intloko ebuhlungu nokuphuthelwa. Ebantwaneni, kuyenzeka ukuba ezi mpawu zibe negalelo ekwenyukeni kwe-myopia (ukubona kufutshane) okuqatshelwe ukusukela kubhubhani we-COVID-19. Nangona kunjalo, uphando olongezelelweyo luyafuneka kule ndawo ukufumanisa ukuba ukusetyenziswa kweelensi eziluhlaza okwesibhakabhaka kubantu abancinci kunokuba nemiphumo engalindelekanga ekuphuhliseni ubude be-ocular axial ngokusebenzisa i-Purkinje rod-cone shift. Le yinkqubo yebhayoloji entsonkothileyo ephantsi kophando olunzulu ngoku.
