Kubathengisi bezingubo zamehlo ngobuningi, ukwazi umehluko phakathi kwamalensi aqhubekayo kanye namalensi amabili kuyindlela enhle yokuhlangabezana kangcono nezidingo zamakhasimende ahlukene.
Lo mhlahlandlela uzokusiza ukuthi uqonde kalula izici nezinzuzo zamalensi womabili, okukuvumela ukuthi wenze ukukhetha okunolwazi oluthe xaxa lapho uthenga.
I-Optical EfaneleAmalensi Aqhubekayo:
Okuhlangenwe nakho okubonakalayo okungenamkhawulo:Ukushintsha okubushelelezi kusuka eduze kuya kude, kufaneleka kakhulu kumakhasimende adinga ukulungiswa kwe-multifocal kodwa angafuni umugqa ocacile wokuhlukanisa.
Ukwamukelwa okuphezulu emakethe: Ukubukeka kwesimanje, okuthandwa amakhasimende aphishekela imfashini nokusebenza kahle.
Amalensi e-Bifocal:Isidingo sendabuko: Kukhona umugqa ocacile ohlukanisa phakathi kwe-myopia ne-hyperopia, ethandwa kakhulu phakathi kwabantu asebekhulile abajwayele ukwakheka kwelensi yakudala.
Okungabizi kakhulu:Intengo ivame ukuba phansi, okukhanga kakhulu abathengi abaqaphela ukusebenza kahle kwezindleko.
Indlela yokukhetha umkhiqizo ofanele imakethe:
Okuthandwa yikhasimende:Ukuba nezinhlobo zombili zamalensi kunganelisa amakhasimende aphishekela ukuguquguquka kanye namakhasimende anaka kakhulu intengo.
Isu Lokuthengisa Ngobuningi: Thola amanani akhethekile emikhiqizweni efunwa kakhulu ngokuthenga ngobuningi ukuze uthuthukise ukuncintisana.
Kungakhathaliseki ukuthi amakhasimende akho ayizitolo ezizimele ze-optical noma amaketanga amakhulu, ukuqonda umehluko phakathi kwamalensi aqhubekayo kanye namalensi e-bifocal kungakusiza ukuthi uthuthukise kangcono umkhiqizo wakho futhi uthuthukise ukwaneliseka kwamakhasimende. Ukuze uthole ulwazi olwengeziwe ngokuthenga ngobuningi noma izinsizakalo ezenziwe ngokwezifiso, sicela ukhululeke ukuxhumana nethimba lethu lokuthengisa.
