Okwangoku, abantu abaninzi bakholelwa ukuba okukhona iiglasi ezibiza kakhulu, kokukhona zibhetele!Ukuqonda le psychology yabathengi, iivenkile zamehlo zihlala zisebenzisa i-refractive index njengendawo yokuthengisa ukunyusa amaxabiso eeglasi ukuze kufumaneke inzuzo ephezulu kwezoqoqosho.Ukuphakama kwesalathisi se-refractive, i-lens encinci, iphezulu ibakala, kwaye ixabiso eliphezulu!Ngoko ngaba yinyani ukuba isalathisi esiphezulu seeglasi, kungcono?Makhe sithethe ngayo.
Iilensi zamehlo ezilungileyo kufuneka zibhekiselele kwiilensi ezineempawu ezintle zokukhanya, ezibonakaliswa kukukhanya okuphezulu, ukusasazwa okuncinci, ukumelana nokunxiba kakuhle, ukhuseleko oluluqilima lwe-ultraviolet, kunye nokhuseleko olululo lwemitha.
Ngokuqhelekileyo i-refractive index ye-lens ibandakanya i-1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.I-Myopia inokohlulwa ibe yi-myopia epholileyo (ngaphakathi kwe-3.00 degrees), i-myopia ephakathi (phakathi kwe-3.00 kunye ne-6.00 degrees), kunye ne-myopia ephakamileyo (ngaphezu kwe-6.00 degrees).Ngokubanzi, i-myopia ethambileyo nephakathi (i-flat ukuya kuma-400 degrees) I-CHOICE i-refractive index yi-1.56 Kulungile, (i-300 degrees ukuya kuma-600 degrees) kwi-1.56 okanye i-1.61 ezi ntlobo zimbini ze-refractive index zikhetha ngokufanelekileyo ngakumbi, i-600 degrees ngasentla ingaqwalasela i-1.67 okanye i-1.74 isalathiso serefraktive lens.Ngokuqinisekileyo, ezi azikho ngokupheleleyo, ngokukodwa ngokumalunga nokukhethwa kwesakhelo kunye nemeko yangempela yamehlo abo ukuba anqume.
I-index ye-refractive ephezulu, i-lens encinci, iphezulu iteknoloji efunekayo, ixabiso eliphezulu, kodwa inkcazo ephantsi, i-index refractive index iya kuba!
I-index ye-refractive ephezulu iphezulu, i-refraction ngakumbi iyenzeka emva kokuba ukukhanya kudlule kwi-lens, kwaye i-lens incinci.Nangona kunjalo, i-index ye-refractive ephezulu iphezulu, i-dispersion phenomenon ibaluleke kakhulu, ngoko ke i-lens ephezulu ye-refractive index inenani eliphantsi le-Abbe.Ngamanye amazwi, isalathisi se-refractive siphezulu, i-lens iyancipha, kodwa ukukhanya kombala akucebile njenge-avareji ye-1.56.Iilensi eziphezulu ze-refractive index zidla ngokusetyenziswa kuphela kumawakawaka amadigri.
Inzuzo ephambili ye-high refractive index lens bubuncinci babo, obungakhokelela ekusebenzeni kakuhle kwamehlo.Abathengi ekukhetheni iilensi, kufuneka bakhethe ngokweedigri zamehlo ezahlukeneyo ukuze bahambelane nezabo, ukusebenza ngokugqwesileyo kwelensi, ukusukela ngokuyimfama kwesalathiso se-refractive ephezulu ayinqweneleki, ifanelekileyo yeyona nto ibalulekileyo!
