WIza ekukhetheni izibuko zamehlo, sivame ukubhekana nesinqumo esibalulekile: amalensi ayindilinga noma amalensi afanayo? Ngenkathi amalensi ayindilinga abe yikhetho elijwayelekile, amalensi afanayo aqhamuke njengenye indlela entsha enohlobo lwezinzuzo. Lo mbhalo uzohlola umehluko phakathi kwamalensi ayindilinga futhi asperical, bese uxoxa ngezinzuzo zamalensi afanayo.
Ukuchazwa nokwehluka:
Umehluko omkhulu phakathi kwamalensi ayindilinga nama-asperical ulele esimweni sawo kanye nokuvuthwa kwawo. Ama-lens ayindilinga anomfaniswano we-lens kuyo yonke lens, kuyilapho ama-lens asperical anama-curvature angajwayelekile angenziwa ngokwezifiso ngokusekelwe esimweni samehlo somuntu.
Inzuzo 1: ukubukeka okwengeziwe kwemvelo
Enye yezinzuzo ezisemqoka ze-aspericalAmalensi ukuthi anikeza ukubukeka kwemvelo ngokwengeziwe. Uma kuqhathaniswa namalensi ayindilinga, i-curvature yama-lens asperical ingazivumelanisa kangcono ne-curvature yeso, ukunciphisa ukuhlanekezela kwalo lens. Lokhu kusho ukuthi abagqokile ama-asperical lens bangabona izithombe ngokucacile nangokuyiqiniso, ngaphandle kokukhathazeka ngokukhishwa kwezimo zelensi ezibonakalayo.
Inzuzo 2: Inkambu ebanzi yokubuka
Ngaphezu kwenzuzo yobuhle, ama-lens asperical futhi anikela ngenkundla ebanzi yokubuka. Ama-lens asperical aklanyelwe ukucubungula isikhundla somfundi kanye ne-curvature ye-retina, ehlisa ukuhlanekezela okubangelwa ukushintshana kwe-lens esondela ekubukekeni kwawo kwasekuqaleni. Lokhu akuhlinzeki kuphela abagqokile okuhlangenwe nakho okubonakalayo okucacile kepha futhi kusiza nokudambisa ukukhathala kwamehlo.
Inzuzo 3: Ilensi elula
Ama-lens asperical ajwayele ukulula kunelensi eyindilinga enesimilo esifanayo. Lokhu kungenxa yokuthi ama-lens asperical ahlelwe ngokwezidingo ezidingakalayo, ukugwema imfucuza yezinto ezibonakalayo engadingekile. Ngenxa yalokhu, abagqokwana bangajabulela okuhlangenwe nakho kokugqoka okuthe xaxa ngenkathi benciphisa umthwalo ebunzini nasekhaleni lekhala, ukunciphisa ingcindezi.
Ukukhetha izibuko ezilungile kuyisici esibalulekile sokunakekelwa komuntu siqu. Ama-lens asperical anikela ngokukhetha okusha kokufakelwa kwamehlo ngamehlo ngokuhlinzeka ngokubukeka okungokwemvelo, inkambu ebanzi, namalensi alula. Lapho udinga ukuthenga izibuko ezintsha, cabanga amalensi afanayo ngokuhlangenwe nakho okubonakalayo okunethezekile futhi okucacile.
