Uninzi lweelensi ze-aspheric nazo ziilensi ezine-index ephezulu. Ukudibanisa uyilo lwe-aspheric kunye nezixhobo zelensi ezine-index ephezulu kudala ilensi ebonakala ngathi incinci, incinci kwaye ilula kuneelensi zeglasi okanye zeplastiki eziqhelekileyo.
Nokuba ubona kufutshane okanye ubona kude, iilensi ze-aspheric zincinci kwaye zikhaphukhaphu kwaye zincinci kuneelensi eziqhelekileyo.
Iilensi ze-Aspheric zincinci kakhulu kuzo zonke iiresiphi, kodwa umahluko uphezulu kakhulu kwiilensi ezilungisa ubungakanani obukhulu bokubona kude. Iilensi ezilungisa ukujonga kude (iilensi ezijiyileyo okanye "ezingaphezulu") zityebile embindini kwaye zincinci emaphethelweni azo. Okukhona iresiphi inamandla, kokukhona umbindi welensi uvuthuluka ngakumbi ukusuka kwifreyimu.
Iilensi ze-Aspheric plus zinokwenziwa ngee-flat curves ezininzi, ngoko ke akukho kuvuleka kwelensi kwifreyimu. Oku kunika i-eyecloth i-profile ethambileyo nenomtsalane ngakumbi.
Kwakhona kwenza kube nokwenzeka ukuba umntu one-prescription enamandla anxibe uluhlu olubanzi lweefreyimu ngaphandle kokukhathazeka ngokuba iilensi zinkulu kakhulu.
Iilensi zeglasi zamehlo ezilungisa i-myopia (iilensi ezigobileyo okanye "ezincinci") zinesimo esahlukileyo: zincinci kakhulu embindini kwaye zinkulu kakhulu emaphethelweni.
Nangona isiphumo sokunciphisa umzimba soyilo lwe-aspheric singenamandla kangako kwiilensi ze-minus, sisabonelela ngokuncipha okubonakalayo kobukhulu bomphetho xa kuthelekiswa neelensi zesiqhelo zokulungisa i-myopia.
Imbono Yendalo Ngakumbi Yehlabathi
Ngeendlela zoyilo lweelensi eziqhelekileyo, kukho ukuphazamiseka okuthile okubangelwa kukujonga kude nombindi welensi — nokuba amehlo akho ajonge ekhohlo okanye ekunene, ngaphezulu okanye ngaphantsi.
Iilensi eziqhelekileyo ezingqukuva ezinomyalelo onamandla wokubona izinto kude zibangela ukwandiswa okungafunekiyo. Oku kwenza izinto zibonakale zinkulu kwaye zisondele kunokuba zinjalo ngokwenene.
Uyilo lweelensi ze-Aspheric, kwelinye icala, luyanciphisa okanye lususe oku kugqwetheka, nto leyo edala umbono obanzi kunye nombono ongcono wecala. Le ndawo ibanzi yomfanekiso ocacileyo yiyo loo nto iilensi zekhamera ezibizayo zinemizobo ye-aspheric.
Nceda uzincede ukhethe ilensi entsha ukuze ubone ihlabathi lokwenyani kwiphepha
