Wxa kuziwa ekukhetheni iindondo zamehlo, sihlala sijongene nesigqibo esibalulekileyo: iilensi ezingqukuva okanye iilensi ze-aspherical?Ngelixa iilensi ezingqukuva iye yaba lukhetho oluphambili, iilensi ze-aspherical ziye zavela njengenye indlela entsha enoluhlu lweenzuzo.Eli nqaku liza kuphonononga umahluko phakathi kweelensi ezingqukuva kunye ne-aspherical, kwaye lixoxe ngezinto ezilungileyo zeelensi ze-aspherical.
Ingcaciso kunye nomahluko:
Umahluko ophambili phakathi kweelensi ezingqukuva kunye ne-aspherical ilensi kukumila kunye nokugoba.Iilensi ezingqukuva zinegophe elifanayo kwilensi yonke, ngelixa iilensi ze-aspherical zineegophe ezingaqhelekanga ezinokuthi zenzelwe umntu ngokusekwe kwimeko yeliso lomntu.
I-Advanteji 1: Imbonakalo yeNdalo engaphezulu
Enye yeenzuzo eziphambili ze-asphericaliilensi kukuba zibonelela ngenkangeleko yendalo.Xa kuthelekiswa neelensi ezingqukuva, ukugoba kweelensi ze-aspherical kunokulungelelanisa ngakumbi ukugoba kwamehlo, ukunciphisa ukugqwethwa kobume be-lens.Oku kuthetha ukuba abathwali bee-lens ze-aspherical banokubona imifanekiso ngokucacileyo nangokwenyani, ngaphandle kokukhathazeka malunga nokuphuma kweemilo ze-lens kubonakala kwabanye.
I-advanteji yesi-2: Indawo ebanzi yokujonga
Ukongeza kwinzuzo yobuhle, iilensi ze-aspherical nazo zibonelela ngenkalo ebanzi yokujonga.Iilensi ze-aspherical zenzelwe ukuqwalasela indawo yomfundi kunye ne-curvature ye-retina, ukunciphisa ukuphazamiseka okubangelwa ukuguqulwa kokukhanya kunye nokuvumela ukuboniswa kwezinto kwi-lens ukuba kusondele kwimbonakalo yazo yangaphambili.Oku akuboneleli nje kuphela abathwali abanamava okubonakalayo okucacileyo kodwa kunceda ekunciphiseni ukukhathala kwamehlo.
I-Advanteji yesi-3: ILens eKhala
Iilensi ze-aspherical zihlala zikhaphukhaphu kuneelensi ezingqukuva ezinomyalelo ofanayo.Oku kungenxa yokuba iilensi ze-aspherical zilungiselelwe ngokusekwe kwiimfuno zomntu ngamnye, kuthintelwa inkunkuma yezinto ezingeyomfuneko.Ngenxa yoko, abathwali banokunandipha amava okunxiba ngokukhululekileyo ngelixa benciphisa umthwalo ebunzi kunye nebhulorho yempumlo, ukunciphisa uxinzelelo.
Ukukhetha izibuko zamehlo ezichanekileyo kuyinkalo ebalulekileyo yokunyamekela komntu.Iilensi ze-aspherical zibonelela ngokhetho olutsha lwabathwali beglasi yamehlo ngokubonelela ngenkangeleko yendalo ngakumbi, indawo ebanzi yokujonga, kunye neelensi ezikhanyayo.Xa ufuna ukuthenga iiglasi zamehlo amatsha, qwalasela iilensi ze-aspherical ukuze ube namava okubona akhululeke ngakumbi nacacileyo.
