Izindaba ezidinga ukunakwa
①Umbani izingilazi ezifanayo, usayizi womaziyo uyadingeka ngokuqinile lapho ukhetha uhlaka. Ububanzi nokuphakama kohlaka kufanele kukhethwe ngokuya ngebanga le-Pupil.
②BAFT egqoke izibuko, lapho ebheka izinto ezinhlangothini zombili, ungathola ukuthi incazelo incishisiwe futhi into ebonakalayo ichithiwe, okujwayelekile kakhulu. Ngalesi sikhathi, udinga ukuguqula ikhanda lakho kancane bese uzama ukubona kusuka enkabeni yelensi, futhi ukungaphatheki kahle kuzonyamalala.
"Lapho ephuza phansi, izibuko kufanele zenziwe ziphansi ngangokunokwenzeka zivela endaweni engenhla ukuze zibone.
I-④glaucoma, isifo samehlo, isifo samehlo esibi, umfutho wegazi ophakeme, isicebele somebele wesibeletho kanye nabanye abantu abanconywa ukusisebenzisa.
Uke wezwa ngokusondeza izibuko? Kusuka kulensi yokugxila okukodwa, amalensi we-biforal namalensi we-multifute aphakathi,
Amalensi we-Multifute aphakathi asetshenziswa kabanzi ama-lens we-Myopia alawulwa yintsha, ama-anti-ukukhathala lens yabantu abadala kanye namalensi athuthukayo kubantu abaneminyaka ephakathi nabantu abadala nabadala. Ngabe uyazi ngempela amalensi we-multifucyus athuthukayo?
01Izindawo ezintathu ezisebenzayo ze-MultiFocus Lens
Indawo yokuqala yokusebenza itholakala engxenyeni engenhla ye-lens Remote ndawo. Indawo ekude iyi-degree edingekayo ukubona kude, yayisetshenziselwa ukubona izinto ezikude.
Indawo yesibili yokusebenza itholakala eduze komphetho ophansi welensi. Indawo yokusondela yi-degree edingekayo ukubona eduze, isetshenziselwa ukubona izinto eziseduze.
Indawo yesithathu yokusebenza yingxenye ephakathi exhuma lokhu okubili, okubizwa ngokuthi yindawo ye-gradient, okuqhubeka kancane futhi ngokuqhubekayo ukuguquka kusuka kude kuya kokuseduze, ukuze ukwazi ukukusebenzisa ukubona izinto zebanga eliphakathi.
Ukusuka kwangaphandle, ama-lens we-multifpective multifOcus awahlukile kumalensi ajwayelekile.
02Umphumela Welensi Ye-MultiFestic
Ama-lens we-multifutestic amaningi ama-multifucus aklanyelwe ukuhlinzeka iziguli nge-presbyopia ngendlela yemvelo, elula nenethezekile yokulungiswa. Ukugqoka ama-lens athuthukayo kufana nokusebenzisa ikhamera yevidiyo. Ingilazi ezimbili zingabona kude kakhulu futhi eduze, kanye nezinto eziphakathi nebanga. Ngakho-ke sichaza ama-lens athuthukayo njenge- "Zoom Lens", izingilazi ezimbili zilingana namabili amaningi ezingilazi.
② Ukunciphisa ukunciphisa ukukhathala okubukwayo futhi kulawule izinga lokuthuthukiswa kwe-Myopia, kepha akuzona zonke izingane ezilungele ukugqoka izingilazi eziphakeme kakhulu, i-lens inomphumela othile ekushintsheni kwezingane ze-myopia ezingenalutho .
QAPHELA: Njengoba iningi leziguli ze-myopia zino-oblique zangaphandle kunokuba i-oblique yangaphakathi, inani labantu abalungele ukugqoka izingilazi zokugxila okuphezulu kokulawula i-myopia zilinganiselwe kakhulu, zibalwa ngamaphesenti ayi-10 kuphela ezingane nentsha.
Ama-lens athuthukayo nawo angasetshenziswa ukunciphisa ukukhathalela okubonakalayo kubantu abasebasha nabaphakathi. Njengomgogodla womphakathi, ukukhathala kwamehlo kwabasebasha nabaphakathi kudala futhi kufanelekile ukunakwa. Ama-lens athuthukayo angefanela ama-lens wokulwa nokukhathala ukuze anciphise ukukhathala okubonakalayo kubasebenzisi bekhompyutha, futhi futhi angasetshenziswa njenge-lens yenguquko yokuqinisekisa umbono omude, ophakathi nowokugxila kakhulu ngokuzayo.
03Ukuzikhethela kwezibuko ze-multifosal eziqhubekayo
Izidingo Zokwakheka
Gwema ukukhetha ozimele nge-Bevel enkulu yamakhala ngoba indawo ephezulu yamafreyimu anjalo ayincane.
Izidingo Zezinto Ezibonakalayo
Kungcono ukungakhethi amapuleti namafreyimu we-tr ngaphandle kwamaphilisi ekhale. Lokhu kungenxa yokuthi ibanga eliphakeme lamafreyimu anjalo lincane kakhulu (kufanele ligcinwe cishe nge-12mm elijwayelekile), iso eliseduze alikwazi ukufinyelela isikhundla sendawo eseduze nendawo, futhi kunzima ukulungisa ukutsheka I-angle yezibuko.
Usayizi wesicelo
Ukuphakama okuqondile okuhambelana nesikhundla se-Pupil sohlaka kufanele kuhlangane ngokujwayelekile izidingo ezichazwe ngumkhiqizo, okuvame kakhulu noma zilingana nezidingo zobude be-16mm +. Uma kunezidingo ezikhethekile, kufanele ubheke kwizidingo zelensi ukukhetha usayizi ofanele wohlaka.
Izidingo Zokusebenza
Amafreyimu anokuqina okuhle kufanele akhethwe ukugwema ukuguquguquka okuvama kwezibuko ezithinta izidingo zokusebenzisa. Izibuko zingagcinwa endaweni enamadigri ayi-10 kuye kwayi-15. Ubuso obugobile bohlaka kufanele bavumelane nemikhuba yobuso be-Weef. Ubude, isilayidi nokuqina kwesibuko kufanelekile ukugqoka okujwayelekile.
