Njengamanje, abantu abaningi bakholelwa ukuthi izibuko ezibiza kakhulu, kungcono!Ukuze ziqonde le psychology yabathengi, izitolo zamehlo zivame ukusebenzisa inkomba ye-refractive njengendawo yokuthengisa ukuze kwenyuswe intengo yezibuko ukuze zithole izinzuzo eziphezulu zezomnotho.Uma iphezulu inkomba ye-refractive, i-lens iba mncane, iphakamisa izinga, futhi intengo ephezulu!Ngakho-ke kuyiqiniso yini ukuthi ukuphakama kwenkomba yezibuko yezibuko, kungcono?Ake sixoxe ngakho.
Amalensi okukhanya amahle kufanele abhekisele kumalensi anezici ezinhle zokubona, abonakala ekudluliseni ukukhanya okuphezulu, ukuhlakazeka okuncane, ukumelana nokugqokwa okuhle, ukuvikeleka okuqinile kwe-ultraviolet, nokuvikela okuhle emisebeni.
Ngokuvamile inkomba ye-refractive yamalensi ihlanganisa 1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.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, i-myopia ethambile futhi emaphakathi (eyisicaba ukuya kumadigri angu-400) Inkomba ye-CHOICE ephindaphindayo ithi 1.56 KULUNGILE, (amadigri angu-300 ukuya kwangu-600) kokuthi 1.56 noma 1.61 lezi zinhlobo ezimbili zenkomba ye-refractive ikhetha okufanele kancane, ama-degree angu-600 ngenhla angacabangela u-1.67 noma 1.74 I-refractive index lens.Yiqiniso, lezi azikho ngokuphelele, ikakhulukazi ngokusho kokukhethwa kwefreyimu kanye nesimo sangempela samehlo abo ukunquma.
Ukuphakama kwenkomba ye-refractive, i-lens encane, iphakeme ubuchwepheshe obudingekayo, intengo ephezulu, kodwa incazelo ephansi, inkomba ye-refractive izoba ephansi!
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, inkomba ye-refractive iphakeme, i-lens incane, kodwa ukugqama kombala akucebile njengesilinganiso esingu-1.56.Amalensi aphezulu e-refractive index ngokuvamile asetshenziselwa izinkulungwane zamadigri kuphela.
Inzuzo eyinhloko yama-lens aphezulu e-refractive index wubuncane bawo, obungaholeli ekusebenzeni okuhle kokubona.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!
