Kubathengisi bezinto zokuhombisa amehlo ngobuninzi, ukwazi umahluko phakathi kweelensi eziqhubekekayo kunye neelensi ze-bifocal yindlela elungileyo yokuhlangabezana ngcono neemfuno zabathengi abahlukeneyo.
Esi sikhokelo siya kukunceda uqonde ngokulula iimpawu kunye neenzuzo zeelensi zombini, nto leyo ekuvumela ukuba wenze ukhetho olunolwazi ngakumbi xa uthenga.
I-Optical efanelekileyoIilensi eziqhubekekayo:
Amava angabonakaliyo:Utshintsho oluthambileyo ukusuka kufutshane ukuya kude, lufanelekile ngakumbi kubathengi abafuna ukulungiswa kwe-multifocal kodwa abafuni umgca ocacileyo wokwahlulahlula.
Ukwamkelwa okuphezulu kwimarike: Inkangeleko yanamhlanje, ethandwa ngabathengi abalandela imfashini kunye nokusebenza kwayo.
Iilensi zeBifocal:Imfuno yendabuko: Kukho umgca ocacileyo owahlula phakathi kwe-myopia kunye ne-hyperopia, ethandwa kakhulu ngabantu abadala abaqhelene noyilo lwelensi yakudala.
Ixabiso eliphantsi:Ixabiso lidla ngokuba liphantsi, nto leyo ebatsala ngakumbi abathengi abaqwalasela indlela esetyenziswa ngayo imali.
Indlela yokukhetha imveliso efanelekileyo kwimarike:
Ukhetho lomthengi:Ukuba neentlobo zombini zeelensi kunokwanelisa abathengi abafuna ukuguquguquka kunye nabathengi abanikela ingqalelo ngakumbi kwixabiso.
Icebo lokuthengisa ngobuninzi: Fumana amaxabiso akhethekileyo kwiimveliso ezifunwa kakhulu ngokuthenga ngobuninzi ukuphucula ukhuphiswano.
Nokuba abathengi bakho baneevenkile ezizimeleyo ze-optical okanye ziitsheyini ezinkulu, ukuqonda umahluko phakathi kweelensi eziqhubekekayo kunye neelensi ze-bifocal kunokukunceda uphucule imveliso yakho kwaye uphucule ulwaneliseko lwabathengi. Ukuze ufumane ulwazi oluthe kratya malunga nokuthengwa kwempahla eninzi okanye iinkonzo ezenzelwe wena, nceda unxibelelane neqela lethu lokuthengisa.
