Ilensi eqhubelekayo kumphezulu wefom ekhululekileyo inommandla omkhulu we-30% wokujonga kunelensi yemveli eqhubekayo.
Ilensi eqhubelekayo yomphezulu wangaphakathi yodlula uyilo lwemveli oluqhubekayo.
Kubantu abanxibileyo abohlukeneyo, ukubalwa kokukhanya kwelensi yokukhanya kwenziwa ngokokukhanya okuchazwe ngugqirha, kwaye eyona mpembelelo yokunxiba yelensi eqhubekayo ifaniswe kwangaphambili, emva koko imemori yogcino lwenkqubo y isetyenziselwa ukusetyenzwa ngokuchanekileyo kokusika ukunciphisa okubonakalayo. ingxaki yokugqwesa intsimi.Phantsi, bonelela ngomgangatho obalaseleyo wokubonwayo.Ngalo lonke ixesha le-lens eqhubekayo esele imile ngokugqibeleleyo inommandla okhululekileyo kunye nendalo ebanzi yombono kwindawo ekude, ephakathi nakufutshane, kwaye kulula ukuziqhelanisa, izisa amava abonakalayo angenakuthelekiswa nanto kumntu oyinxibileyo!
● Indawo ebanzi yokujonga: umntu onxibileyo unokufumana umbono ocacileyo oqhubekayo ukusuka kwindawo ekude ukuya kwindawo ekufutshane ngokusebenzisa i-lens ye-multifocal eqhubekayo, kwaye unokubona ngokucacileyo umgama omde, ophakathi kunye nomfutshane.
● Umbono oguqukayo ucacile : xa ukukhanya kuhamba ukusuka kwindawo ukuya kwenye, inkqubo yokulungiswa kwamehlo iyindalo, kwaye ayiyi kubangela ukuba nesiyezi kunye nokungaboni kakuhle ngenxa yokuxhuma imifanekiso.
● Intuthuzelo enkulu: umbono wendalo, ngokuhambelana ne-physiological optics, ukulungelelanisa ngokukhawuleza kunye nokunciphisa ixesha lokulungelelanisa.
● Inkangeleko isefashonini ngakumbi: inkangeleko intle ngakumbi kune-bifocals, akukho mgca wokwahlula ifilimu encinci, kwaye akukho mmandla oyimfama we-annular.
Jonga ngokusondeleyo kwaye ubone kude, esinye isibuko sokusetyenziswa okuninzi, umsebenzi wokulungisa umbono, ukhululekile ngakumbi ukunxiba
Ukuhambisa uyilo oluqhubela phambili kumphezulu wangaphakathi kwandisa kakhulu intsimi yokujonga indawo nganye yelensi.Enye into echaphazela intsimi yokujonga ivela kwi-aspheric okanye i-astigmatic aspheric design yendawo yangasemva.Uyilo lwe-aspheric lwenza i-radius ye-cur vature ye-apex ye-lens flat ukuze i-lens ikwazi ukusondela kwi-eyeball, ekwayinto ebalulekileyo ekwandiseni intsimi yokujonga.
Inkcazo yelensi
Yamkela umgaqo woyilo othambileyo we-asymmetric ukuhlangabezana nebhalansi yokude, phakathi nakufutshane
Kwaye indawo ye-astigmatism kumacala omabini iye yaphuculwa ngokufanelekileyo ukunyusa ibala lokujonga lens ngama-35%.
Yenza ukuba umntu onxibileyo azive ekhululekile kwinguqu yendawo nganye yokukhanya kwaye kulula ukuziqhelanisa.

● Inkalo yokujonga ngokubanzi: umntu onxibileyo unokufumana umbono ocacileyo oqhubekayo ukusuka kwindawo ekude ukuya kwindawo ekufutshane ngokusebenzisa i-lens ye-multifocal eqhubekayo, kwaye unokubona umgama omde, ophakathi kunye nomfutshane ngokucacileyo.
