Kulezi zinsuku, izinkinga zokubona kwentsha ziye zadonsela ukunaka okwandayo. Amalensi e-defocus amaningi, anomklamo wawo oyingqayizivele, adlala indima ebalulekile ekunciphiseni ijubane lokwelulwa kwe-axial kanye nokuvikela ukubona. Ngezansi isingeniso samalensi amahlanu e-defocus amaningi asebenza kahle kakhulu avela ku-I-Optical Efanele—nganye yenzelwe ukuxazulula izindawo ezithile zobuhlungu bokubona kwentsha, ihlangabezana nezidingo ezahlukene.
1. Ilensi ye-PC Annular Multi-Point Defocus: Elula futhi Engamelani Nomthelela Wentsha Ekhuthele
Ihlose ezingxenyeni ezibuhlungu zentsha ethanda ezemidlalo (ukuphuka kalula kwelensi) futhi echitha isikhathi eside (ukucindezela kwebhuloho lamakhala), le lensi ihlanganisa ukusebenza kahle nokuvikelwa:
Umklamo kanye Nomsebenzi:Isebenzisa izindandatho zokuphambuka ezisezingeni eliphezulu ezihambisana ne-astigmatic ukuze ithuthukise ngempumelelo izimpawu zokususa ukugxila, ihambisana nomklamo wokwenza ngcono umbono wentsha onciphisa izinga lokunwebeka kwe-axial, ivikele intuthuko yokubona kwentsha.
Inzuzo Yezinto Ezibalulekile:Isebenzisa izinto ze-HPC ezisebenza kahle kakhulu—ezilula ukunciphisa ingcindezi yebhuloho lamakhala, futhi inokumelana okuhle kakhulu nokushayisana, igwema ukuphuka kwelensi okubangelwa ukuwa ngengozi ngesikhathi semidlalo.
Ukuzivumelanisa Nokubona: Umklamo wamalensi amaningi ufanelana nemikhuba yokubona yentsha, okudala indawo yokubuka ezinzile nephephile, okungelula ukuyibangela ukukhathala kokubuka ngisho nangemva kokugqokwa isikhathi eside.
2. Ilensi ye-PC Polygonal Multi-Point Defocus: Iqinisekiswe Emhlabeni Wonke Yokulawula Umbono Ozinzile
Kubazali abakhathazekile "ngemiphumela yokulawula umbono engathembekile" kanye "nokuphila kwenkonzo yelensi emfushane", le lensi incike kubuchwepheshe obuyinhloko kanye nezinto ezisezingeni eliphezulu ukuxazulula izinkinga:
Ubuchwepheshe Obuyinhloko:Iqukethe umklamo wokusabalalisa amachashazi-matrix obambezela ukunwebeka kwe-axial futhi ulawule ukulahleka kokubona; isebenzisa ubuchwepheshe be-defocus obudumile emhlabeni wonke, obunomphumela oqinisekisiwe ekuvimbeleni ukukhula kwamehlo ngokuqinisekiswa kwezokwelapha.
Ukugqoka Nokucaca:Isebenzisa ukugqoka okubonakalayo okunembile kwaseJalimane—iqinisekisa ukuhanjiswa kokukhanya okuphezulu ukuze kuthathwe izithombe ezicacile, futhi inokumelana okuqinile nokuguguleka, igcina ukusebenza okuhle kokukhanya ngisho nangemva kokusetshenziswa isikhathi eside (njengokusula njalo).
Ukuphepha Kwezinto Ezibalulekile:Yenziwe ngezinto ze-PC ezithunyelwe eJapan, enokuqina okuphezulu kakhulu kanye nokuguquguquka okuhle, okungelula ukuyiqhekeza noma ukuyiguquguqula, ifanele intsha enezindlela zokuphila ezisebenzayo.
3. Ilensi ye-1.60 MR Tough 8th Generation - Annular Multi-Point Defocus Lens: Ihambisana Nezinga Elijwayelekile Lokuvikela Okuphelele
Ihlose izidingo zentsha ene-myopia ephakathi kuya kwephezulu (ekhathazekile ngokujiya kwelensi, ukucaca kwezithombe, kanye nokuhambisana nayo), le lensi ihlanganisa ukuminyana okuphezulu, amazinga aphezulu, kanye nokuqina okuphezulu:
Ubuningi be-Defocus:Ihlonyiswe ngama-micro-lens angu-1,092 ukuze kufezwe i-multi-point micro-defocus, enobukhulu obuphezulu be-defocus obuphazamisa umbono ngokuphelele, okunciphisa ingozi yokuqhubeka kwe-myopia.
Ukusebenza Kokukhanya:Inenombolo ye-Abbe ephezulu kakhulu engu-40.8 (inombolo ye-Abbe ephezulu isho ukuguquguquka okuncane kwe-chromatic), okuvumela ukuthwebula izithombe okucacile futhi kunciphisa ngempumelelo ukukhathala kokubona okubangelwa ukufunda isikhathi eside noma ukusebenzisa isikrini.
Izinzuzo Eziwusizo:Ihlanganisa ukumelana nomthelela kanye nokumelana nokuguguleka—incane kunamalensi ajwayelekile anamandla afanayo, ilula ukuyiguguleka, futhi akulula ukuyiphula, ifanele ukusetshenziswa kwansuku zonke kanye nemisebenzi yangaphandle.
4. 1.56 Ilensi Yokucisha Ukugxila Okunezingqimba Eziningi Enezingqimba Eziningi: Ukuvimba Ukukhanya Okuluhlaza Kwentsha Enobungani Nesikrini
Kwabancane abasebenzisa imikhiqizo kagesi (omakhalekhukhwini, amaphilisi, amakhompyutha) isikhathi eside (abasengozini yokulimala kokukhanya okuluhlaza okwesibhakabhaka kanye nokulungiswa ngokweqile), le lensi inikeza isivikelo esiqondiwe:
Umklamo we-Defocus:Yakhiwe ngama-micro-lens angu-666 ukuze kube nombono omncane we-micro-defocus, okunikeza ukunakekelwa okuphelele kwempilo yamehlo nokuvimbela ukuqhubeka kwe-myopia ngezindlela eziningi.
Sula Izithombe:Inendawo yokulungisa ephakathi engu-11mm ububanzi (Φ11mm)—ithuthukisa ukujula kokugxila kwe-retina, yenza ukubuka into kucace futhi kuzinze kakhudlwana, igweme ukufiphala lapho ushintsha phakathi kokubona okuseduze nokukude.
Isivikelo Sokukhanya Okuluhlaza okwesibhakabhaka: Ifakwe ungqimba oluqinile oluvimba ukukhanya okuluhlaza okwesibhakabhaka—luvimba ukukhanya okuluhlaza okwesibhakabhaka okuyingozi okufushane (400-450nm) okukhishwa yizikrini, futhi alunawo umbala ophuzi, okuqinisekisa ukuthi akukho ukuphambuka kokubona kombala (isb., akukho ukuphuzi lapho ubuka izikrini ezimhlophe).
Ukuphepha Kokulungisa:Ububanzi bamandla okususa ukugxila kusukela ku-+4.0D kuya ku-+6.5D bandisa ukungalingani, okuvimbela ngempumelelo ukulungiswa ngokweqile (ukugwema "ukujula kwe-myopia ngenxa yokulungiswa ngokweqile").
5. 1.56 Ilensi Egxile Kakhulu: Ushintsho Lokubona Okubushelelezi Kwezigcawu Zansuku Zonke Nezemidlalo
Ihlose ezindaweni ezibuhlungu "zokungaqhubeki okusobala kokubona" kanye "nensimu encane yokubuka" kwamalensi endabuko e-defocus, le lensi igxile ekuthuthukiseni induduzo yokugqokwa:
Umklamo Ogcwele Insimu:Izindawo ezigxile kulensi zisakazwa njalo, okuvumela abagqokile ukuthi babe noshintsho olubushelelezi lapho bebuka izinto (isb., kusukela ebhodini elimnyama kuya encwadini yesikole, kusukela kude kuya eduze), ngaphandle "kokugxuma" okusobala embonweni.
Ukulawula Umbono:Umsebenzi wokungenelela kwe-dynamic defocus ulungisa amandla angaphandle ukuze alingise isimo semvelo sokuguguleka kweso lomuntu, wehlise ijubane lokunwebeka kwe-axial ngenkathi uqinisekisa ukubona okukhululekile.
Inkundla Ebanzi Yokubuka:Isebenzisa ubuchwepheshe bomphezulu obukhululekile—ukugoba kwelensi kulandela ukunyakaza kwamehlo, kwandisa indawo yokubuka ephumelelayo. Kungakhathaliseki ukuthi kusekilasini, kufundwa, noma kudlala i-basketball, kugijima, abagqokile bangajabulela insimu ebanzi nengokwemvelo yombono ngaphandle “kwezindawo ezingaboni” emaphethelweni elensi.
Ohambweni lokuvikela impilo yokubona yentsha, ukukhetha okufanele kwamalensi kudlala indima ebalulekile. Izinhlobo ezinhlanu zamalensi e-defocus asebenza kahle kakhulu asetshenziswe ngenhla, ngezinzuzo zawo zobuchwepheshe ezihlukile kanye nemiklamo eqondiwe, zinakekela izidingo ezahlukahlukene zamaqembu ahlukene entsha—kungakhathaliseki ukuthi ukuqina okulula, ukulawula okuqondile kwe-defocus, ukuvikelwa kokukhanya okuluhlaza okwesibhakabhaka, noma ulwazi lwemvelo lokubona. Njengomkhiqizo wobuchwepheshe ozinikele empilweni yokubona,I-Optical Efaneleibilokhu inamathela emcabangweni wokuhlanganisa ubuchwepheshe obusezingeni eliphezulu nesidingo somsebenzisi. Ngayinye yalezi lensi ze-defocus ezinamaphoyinti amaningi yenziwe ngokulawulwa kwekhwalithi okuqinile kanye nocwaningo olujulile mayelana nokuthuthukiswa kokubona kwentsha, okuhlose ukuhlinzeka ngezixazululo zokuvikela amehlo ezithembekile, ezikhululekile, neziqondene nawe. Uma ufuna imikhiqizo efanele yokulungisa nokuvikela amehlo yentsha,I-Ideal Optical'sUchungechunge lwamalensi e-defocus amaningi luyisinqumo esithembekile, esihambisana nentsha ohambweni lokukhula okunempilo kokubona.
