Kepha ngale kwelensi eyi-multifocal engenazintambo ezibonakalayo, amalensi athuthukayo anika amandla abantu abane-presbyopia baphinde babone kahle kuwo wonke amabanga.
Izinzuzo zamalensi athuthukayo ngaphezulu kwama-bifocals
Ama-bifocal eyeglass lens anamandla amabili kuphela: eyodwa yokubona egumbini elilodwa nakwelinye ngokubona eduze. Izinto eziphakathi, njengesikrini sekhompyutha noma izinto eziseshalofini lesitolo sezitolo, zivame ukufiphala ngama-biforals.
Ukuzama ukubona izinto kulolu hlu "oluphakathi" ngokucacile, abagqoke ama-biforal kufanele bakhuphuke amakhanda abo phezulu naphansi, babheke ngokuhlukile ngakuqala bese benquma ukuthi iyiphi ingxenye yelensi esebenza kangcono.
Ama-lens athuthukayo alingisa kakhulu umbono wemvelo owujabulele ngaphambi kokuqala kwe-presbyopia. Esikhundleni sokuhlinzeka ngamandla amabili amalensi afana nama-bifocals (noma amathathu, njengezikhohla), ama-lens athuthukayo anikeza amandla abushelelezi, angenamthungo wamandla amaningi we-lens wombono ocacile kulo lonke igumbi.
Umbono wemvelo ngaphandle "kokugxuma kwesithombe"
Imigqa ebonakalayo kuma-bifocals kanye nama-Trifocals amaphuzu lapho kuvela khona. Futhi, ngenxa yenani elilinganiselwe lamandla welensi kuma-bifocals kanye nama-trifocals, ukujula kwakho kokugxila ngala ma-lens akhawulelwe. Ukubonwa ngokucacile, izinto kufanele zibe ngaphakathi kohlu oluthile lwamabanga. Izinto ezingaphandle kwamabanga ambozwe amandla we-lens we-bifocal noma ama-trifocal azofiphala futhi ashintshe amandla e-lens.
Amalensi athuthukayo, ngakolunye uhlangothi, aqhakambisa amandla abushelelezi, angenamthungemfuli wombono ocacile kuwo wonke amabanga. Ama-lens athuthukayo ahlinzeka ngokujula okungokwemvelo okungagxili kakhulu ngaphandle kokuthi "gxuma kwesithombe."
Amandla welensi athuthukayo aguquka kancane kancane esuka ePhoyinti ukuze akhombe ngaphezulu kwelensi, enikeza amandla amalensi afanele okubona izinto ngokucacile kunoma yiliphi ibanga.
Inikeza umbono ocacile kuwo wonke amabanga (kunokuba okungenani amabanga amabili noma amathathu ahlukile ahlukile).
Ngombono omuhle kakhulu, induduzo nokubukeka, ungakhetha imigwaqo ebanzi yokuguqulwa okulula futhi okusheshayo kunezizukulwane zokugcina ezithuthukayo. Ungangena ekhasinihttps://www.univveropooptical.com/wideview-product/Ukuhlola imininingwane eminingi ngemiklamo yethu yakamuva eqhubekayo.
