Abantu abaningi asebegqoke izibuko iminyaka
Kungase kube nokungabaza okufana nalokhu:
Ukugqoka izibuko isikhathi eside, akucaci kahle ukuhlukaniswa kwamalensi
I-Myopia kanye ne-hyperopia?Yini i-single-focus ne-multi-focus?
Isiphukuphuku asikwazi ukuhlukanisa umehluko
Ukukhetha amalensi kudida nakakhulu:
Iluphi uhlobo lwamalensi olufanele wena?
Kukhona zonke izinhlobo zemisebenzi?Yiziphi izici engizidingayo?
Kukhona zonke izinhlobo zamalensi;
Uma i-lens ihlukaniswe kusukela ekugxilweni kwayo, ingahlukaniswa ibe ilensi yokugxila eyodwa (i-monophoto), ilensi yokugxila ekabili, ilensi yokugxila eminingi.
Amalensi e-multifocal aqhubekayo, abuye aziwe ngokuthi amalensi aqhubekayo, anezindawo eziningi zokugxila kulens.
Namuhla sizokhuluma ngamalensi aqhubekayo e-multifocal
Iyini ilensi ye-multifocal eqhubekayo?
Izingilazi ze-multifocal eziqhubekayo, ezinamaphoyinti amaningi okugxila ku-lens eyodwa ngesikhathi esisodwa, kancane kancane zishintsha ukusuka endaweni ekude phezulu kwelensi ukuya endaweni eseduze ezansi.
Ukuba namadigri amaningi kulensi efanayo kuhlukaniswe izifunda ezintathu: kude, phakathi nendawo naseduze:
1, indawo ekude yokubuka ephezulu
Isetshenziselwa ukubona ibanga elide, njengokudlala, ukuhamba, njll
2, maphakathi nesifunda esimaphakathi
Ukubona ibanga elimaphakathi, njengokubuka ikhompuyutha, ukubukela i-TV, njll
3. Ukubuka okuphansi eduze nendawo
Isetshenziselwa ukubuka eduze, njengokufunda izincwadi, amaphephandaba, njll
Ngakho-ke, ukugqoka izibuko kuphela, kunganelisa isidingo esikude, bheka, bheka eduze nombono.
Izimo ezijwayelekile ze-physiological:
I-Presbyopia, ebonakala kancane kancane ngokukhula kweminyaka, ibonakala ngokuyinhloko njengokufiphala futhi ayikwazi ukubona izinto ebangeni eliseduze.Lesi simo sizonciphisa ukusebenza kahle komsebenzi futhi sithinte izinga lempilo.
Amalensi e-multifocal aqhubekayo ayisixazululo esihle sale nkinga
With umsebenzi omuhle kakhulu
Okuthandwa kakhulu futhi okufunwayo kusukela ekufakweni ohlwini
