Amalensi amaningi ase-aspheric nawo angamalensi anenkomba ephezulu. Inhlanganisela yomklamo we-aspheric onezinto zamalensi anenkomba ephezulu idala ilensi ebonakala izacile, izacile futhi ibelula kunengilazi evamile noma amalensi epulasitiki.
Kungakhathaliseki ukuthi ubona eduze noma ubona kude, amalensi aspheric mancane futhi alula futhi anephrofayela encane kunamalensi avamile.
Amalensi e-aspheric anephrofayili emincane cishe yazo zonke iziqondiso, kodwa umehluko umangalisa ikakhulukazi kumalensi alungisa amanani aphezulu okubona kude. Amalensi alungisa ukubona kude (convex noma "plus" lens) aminyene phakathi nendawo futhi mancane emaphethelweni awo. Lapho incwadi kadokotela inamandla, yilapho isikhungo se-lens siqhuma kakhulu sisuka kuhlaka.
Amalensi e-aspheric plus angenziwa ngamajika ayisicaba kakhulu, ngakho-ke kukhona ukugobha kancane kwelensi kuhlaka. Lokhu kunikeza izingubo zamehlo zibe mncane, iphrofayili ethopha kakhulu.
Futhi kwenza kube nokwenzeka ngomuntu onencwadi kadokotela eqinile ukuthi agqoke ukukhethwa okukhulu kwamafreyimu ngaphandle kokukhathazeka ngokuthi amalensi aminyene kakhulu.
Amalensi engilazi yamehlo alungisa i-myopia (amalensi e-concave noma “minus”) anomumo ophambene: mancane kakhulu phakathi nendawo futhi aminyene kakhulu onqenqemeni.
Yize umthelela wokunciphisa umzimba wedizayini ye-aspheric umangalisa kancane kumalensi wokususa, usahlinzeka ngokuncishiswa okubonakalayo kogqinsi uma kuqhathaniswa namalensi avamile okulungiswa kwe-myopia.
Umbono Ongokwemvelo Owengeziwe Womhlaba
Ngemiklamo evamile yelensi, okunye ukuhlanekezela kuyadalwa uma ubheka kude nendawo ephakathi nelensi - noma ngabe ukugqolozela kwakho kuqondiswe kwesokunxele noma kwesokudla, ngaphezulu noma ngezansi.
Amalensi ayindilinga avamile anemiyalelo eqinile yokubona kude abangela ukukhuliswa okungafuneki. Lokhu kwenza izinto zibonakale zizikhudlwana futhi ziseduze kunalokho eziyikho ngempela.
Ngakolunye uhlangothi, imiklamo ye-aspheric lens, inciphisa noma iqede lokhu kuhlanekezela, idale indawo ebanzi yokubuka kanye nombono ongcono we-peripheral. Le ndawo ebanzi yesithombe esicacile yingakho amalensi ekhamera abizayo enemiklamo ye-aspheric.
Sicela uzisize ukhethe ilensi entsha ukuze ubone umhlaba wangempela kakhulu ekhasini
