Omunye wemibuzo abantu abaningi abawuzwayo uma befakelwe amalensi uthi, "Iyiphi inkomba ye-refractive oyidingayo?"Ngikholwa ukuthi abantu abaningi abaliqondi leli gama lochwepheshe, ake sifunde ngalo namuhla!
Abantu abaningi emphakathini wanamuhla bakholelwa ukuthi izibuko ezibiza kakhulu, kungcono!Odokotela bamehlo abaningi, bebamba le psychology yabathengi, bavame ukusebenzisa inkomba ye-refractive njengendawo yokuthengisa ukukhulisa intengo yezibuko ukuze bathole izinzuzo eziphezulu zezomnotho.Okusho ukuthi, ukuphakama kwe-refractive index, i-lens ibe mncane, futhi intengo ibiza kakhulu!
Inzuzo eyinhloko yama-lens aphezulu-refractive ubuncane bawo.Abathengi ekukhetheni ama-lens, kufanele bakhethe ngokuya ngamazinga ahlukene wamehlo ukuze bavumelane nezabo, ukusebenza okuhle kakhulu kwe-lens, ukuphishekela okuyimpumputhe kwenkomba ephezulu ye-refractive ayifiseleki, okufaneleka kubaluleke kakhulu!
Ama-lens optical amahle kufanele abhekisele kumalensi anezakhiwo ezinhle ze-optical, abonakala ekudluliseni okuphezulu, ukucaca okuphezulu, ukuhlakazeka okuncane, ukumelana nokugqoka okuhle, ukumboza okuhle kakhulu kanye nomsebenzi omuhle wokuvikela.
Ngokuvamile inkomba ye-refractive yamalensi ihlanganisa 1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.
Ngokombono wochwepheshe ukukhetha inkomba ye-refractive ngokuvamile ngokuya ngokucabangela okuphelele okulandelayo:
1. Izinga le-myopia.
I-Myopia ingahlukaniswa ibe i-myopia emnene (ngaphakathi kwamadigri angu-3.00), i-myopia emaphakathi (phakathi kuka-3.00 no-6.00 degrees), kanye ne-myopia ephakeme (ngaphezu kwamadigri angu-6.00).
Ngokuvamile OKUKHULUMA UKUKHANYA KANYE NE-MYOPIA emaphakathi (amadigri angu-400 ngaphansi kokuthi) I-CHOICE REFRACTIVE INDEX I-1.56 Kulungile, (ama-300 degrees ukuya ku-600 degrees) KU-1.56 NOMA 1.61 lezi IZINHLOBO EZIMBILI zokukhetha kwenkomba ye-REFRACTIVE, ama-degree angu-600 ngenhla angacabangela u-1.611 noma inkomba engu-1. ilensi.
Lapho inkomba ye-refractive iphakeme, ukuphindaphinda kwenzeka kakhudlwana ngemva kokuba ukukhanya kudlule ilensi, futhi i-lens iba mncane.Kodwa-ke, uma inkomba ye-refractive iphakeme, yilapho isimo sokuhlakazeka siba sibi kakhulu, ngakho-ke ilensi yenkomba ye-refractive ephezulu inenombolo ye-Abbe ephansi.Ngamanye amazwi, uma inkomba ye-refractive iphakeme, ilensi iba mncane, kodwa uma ubheka izinto, ukugqama kombala akucebile kangako uma kuqhathaniswa ne-1.56 refractive index.Okushiwo lapha kuwumehluko omncane kuphela ekuqhathaniseni okuhlobene.Ngobuchwepheshe bamanje, i-lens ene-high refractive index nayo inhle kakhulu embonweni.Amalensi aphezulu e-refractive index ngokuvamile asetshenziselwa izinkulungwane zamadigri kuphela.
2. Izidingo zesihloko.
Ukukhethwa kwenkomba ye-refractive ngokusho kwezinga le-myopia akuyona into ephelele, kodwa kufanele kuhlanganiswe nokukhethwa kohlaka kanye nesimo sangempela seso sokunquma.
Manje i-myopic degree ngokuvamile iphakeme, ku-myopia ye-baidu emihlanu kuya kweyisithupha, inkomba ephansi ye-refractive ye-lens izoba ugqinsi, isisindo esihlobene sizoba sikhulu ezimbalwa, ngalesi sikhathi, uma ukuphishekela idigri enhle kuphakeme, siphakamisa ngaphezu kuka-1.61 inkomba ye-refractive, ngaphezu kwalokho lapho ukhetha ifreyimu yesithombe ukuze ugweme uhlobo lwebhokisi elikhulu, ngakho konke okubanzi, izinga lezibuko lobuhle nokunethezeka lihle kakhulu.
Isiphetho: UKUKHETHA INkomba ye-refractive kufanele kusekelwe eselulekweni sikadokotela wamehlo ochwepheshe, ngokuya ngezinga le-myopia, usayizi wefreyimu, izidingo zobuhle, ukunethezeka okubonakalayo, inani lokusetshenziswa nokunye ukucatshangelwa okuphelele, okufanele kubaluleke kakhulu.
