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.
Ngelixa iilensi ze-bifocal zizielensi zokujonga kabini ezilungisa ukude kunye nombono okufutshane, Izinto ezikubude bengalo zisabonakala zimfiliba. Iilensi eziqhubekayo kwelinye icala, zibonisa iindawo ezintathu ezingabonakaliyo zombono- kufutshane, kude naphakathi.
Ukuba uzizigulane ze-presbyopia kwaye uchitha ixesha elininzi ungaphandle, luluvo oluhle ukukhetha iilensi eziqhubekayo zefotochromic. Ngenxa yokuba azikhuseli kuphela amehlo akho kwimitha eyingozi yelanga, kodwa zibonelela ngombono ongenamthungo kunye nokhululekile kwiindawo ezahlukeneyo.
Ukuba ngumntu onxibe iindondo ze-presbyopia ngeentsuku ezinelanga kunokuba yingxaki. Ngaba kufuneka sinxibe iiglasi zethu zefotochromic okanye iiglasi zokulungisa umbono? I-lens ye-photochromic progressive iya kukunceda ukusombulula le ngxaki inkulu kuba olu hlobo lwelensi lunokhuseleko lokukhanya kwelanga kunye nomyalelo wonke kwisibini esinye!
Iilensi zePhotochromic luphawu olongezelelweyo olungeyomfuneko ukulungisa umbono kodwa luluncedo kakhulu kubomi bemihla ngemihla.
Ngokuqhelekileyo abantu abangaphezu kweminyaka engama-40 abane-presbyopia (ukubona kude) kunye nombono ophazamisayo xa besenza umsebenzi osondeleyo okanye befunda umbhalo omncinci. Iilensi eziqhubekayo zingasetyenziselwa abantwana nabo, ukuthintela ukwanda kwe-myopia (ukubona kufutshane).
Nikeza inkangeleko ejongeka mncinci.
Ukubonelela ngokhuseleko oluyi-100% kwimitha yelanga ye-UVA kunye ne-UVB.
Ukunika intsimi ekhululekile kunye neqhubekayo yombono kunye nokuphazamiseka okuncitshisiweyo.
Nika imigama emithathu eyahlukeneyo yokujonga. Akusayi kufuneka uphathe iipere ezininzi zeeglasi ukuze usetyenziswe ngeendlela ezininzi.
Ukuphelisa ingxaki yokutsiba umfanekiso.
Nciphisa amathuba eeyestrain.
