Zithini iilensi eziqhubekayo?

I-lenses eqhubekayo evelaI-Optical efanelekileyosisisombululo esibonakalayo, isiphelo esiphezulu esingqinelanayo kwimfuno yombono womsebenzisi. Ngokungafaniyo ngokufana neelensi eziqhelekileyo, iilensi eziqhubayo eziqhubela phambili zibonelela ngotshintsho olusondeleyo phakathi kwekufuphi, eziphakathi kunye nombono obukhali, zenza ukuba zilungele izigulana zombini.

Ezona mpawu:

Ukulungiswa ngombono:
I-lenses eqhubela phambiliIngayilwa ukuba ilingane nogqirha, indlela yokuphila kunye neemfuno ezibonakalayo kwiimpawu ezahlukeneyo zobuso. Oluyilo olunempumelelo lunciphisa ngokufanelekileyo ukugqwetha okubonakalayo kwaye lubonelela ngamava afanelekileyo kwaye abonakale ngokwendalo, owenziwe buqu ngakumbi kuneilensi zemveli.

Intuthuzelo ephuculweyo kunye nophando:
Nokuba umncedisi uyasebenza kwikhompyuter ixesha elide, esenza imisebenzi yangaphandle, okanye kufuneka atshintshe umbono phakathi komgama ohlukeneyo, iilensi eziqhubela phambili zinokuhlangabezana neemfuno zabo zobuso. Ukuyilwa ngokuchanekileyo kunye nokuthuthuzela okuphezulu kweelensi kwenza ukuba abathengi abaxabisayo umsebenzi kunye nentuthuzelo.

Ukudibanisa ubuhle kunye nomsebenzi:
Iilensi eziqhubela phambili zinenzuzo ebonakalayo. Ngokungafaniyo neelensi ze-bifocal, ezineendawo ezikhethekileyo ezigxile kuzo, iilensi eziqhubela phambili zibonelela ngenguqu egudileyo phakathi kwamanqaku emali, ehambelana kakhulu ngelixa itsiba ngequbuliso emboneni.

Abafanele bazisebenzise:
I-lenses eqhubela phambili inkqubela phambili ilungele kakhulu abantu abanoTysgoopia, oneminyaka engaphezu kweminyaka engama-40 ubudala kwaye banobunzima bokugxila kuluhlu olusondeleyo. Ngaba lukhetho olufanelekileyo kubantu abafuna umbono kodwa bafuna iilensi ezilungiselelwe ngokugqibeleleyo kwiimfuno zabo zokubonwayo. I-lenses eqhubela phambili inomdla nayo yabo bafuna ukuthintela umgca wokwahlula okwahlulahlulwa obonakalayo obonwa kwiilensi ze-biifocal.
