1,Umbono omnye:
Umbono omnyeibandakanya umgama, ukufunda kunye nePlano.
Iiglasi zokufunda zingasetyenziselwa ukubukela ifowuni yesandla, ikhompyutha, ukubhala njalo njalo.Ezi glasizisetyenziselwa ukubona izinto ezikufutshane ngokukodwa, ezinokwenza indawo yokuhlala yamehlo ikhululeke kwaye ingabikho ukudinwa.
Iiglasi ezikude zingasetyenziselwa ukuqhuba, ukunyuka, ukubaleka kunye neminye imisebenzi yangaphandle.Ezi glasizisetyenziselwa ukubona umgama ocacileyo ngakumbi.
Ngoko kukho iiglasi zokwahlula umgama kunye nokufunda.
Iiglasi zePlano ziglasi ngaphandle komyalelo, ezingasetyenziselwa ukukhuselwa komoya kunye nesanti kuphela, okanye ukubonakala okuhle.
2,I-Bifocal
Umyili wayila ubude bojoliso obuphezulu beelensi ukuze bukwazi ukujonga izinto ezingaphezulu kweemitha ezi-3, ngelixa indawo engezantsi yayilungiselelwe ukujonga iimpawu ezikufutshane zendawo.Olu luyilo lwenza umntu onxibe iiglasi abone umgama/kufuphi nezinto ezahlukeneyo.Akuyimfuneko ukukhupha iiglasi, ezibonelela ngokulula kakhulu kubantu be-presbyopia.
3, Abaqhubela phambili
Ilensi eqhubekayoluhlobo lwelensi ekwaziyo ukubona kude nakufuphi.Kukho imimandla emibini engundoqo yokukhanya kuyilo oluqhubekayo kwitshiphu.Icala elisezantsi eliphakathi kwempumlo yindawo ekufutshane;Ukuqhubela phambili kwemifanekiso ebonakalayo kufezekiswa ngommandla wenguqu phakathi kommandla okhangele phambili kunye nommandla osondeleyo.Ukongeza kwisidingo somntu onxibayo ukuba asuse iiglasi xa ejonga izinto ezikude / ezikufutshane, ukuhamba kwamehlo phakathi kobude obuphezulu kunye nobude obuphantsi buqhubela phambili.Ukungalungi kuphela kukuba kukho idigri ezahlukeneyo zokwahluka komfanekiso ogqithisileyo kumacala omabini esilayi esiqhubela phambili, okuya kubangela imvakalelo yokunyuka kumbono weperipheral.
Iiprogressives zibonelela ngotshintsho olugudileyo ukusuka kumgama ukuya phakathi ukuya kufutshane, nazo zonke izilungiso eziphakathi zibandakanyiwe ngokunjalo.Ungajonga phezulu ukuze ubone nantoni na ekude, jonga phambili ukujonga ikhompyuter yakho kwindawo ephakathi, kwaye ujonge phantsi ukuze ufunde kwaye wenze umsebenzi olungileyo ngokukhululekileyo kwindawo ekufutshane.Oko kukuthi, iilensi eziqhubekayo zezona zikufutshane kwindlela umbono wendalo onokuthi ungene ngayo kwiperi yeglasi zamehlo ezichazwe ngugqirha.
