Amalensi awajwayelekile kubantu abaningi, futhi ilensi edlala indima enkulu ekulungiseni i-myopia kanye nokufaka izibuko. Kunezinhlobo ezahlukene zokumboza kumalensi,njengezingubo eziluhlaza okotshani, izingubo eziluhlaza okwesibhakabhaka, izingubo eziluhlaza okwesibhakabhaka-onsomi, ngisho nalokho okubizwa ngokuthi "izingubo zegolide ezingondlovukazi bendawo" (igama elivamile lezingubo ezinombala wegolide).Ukuguguleka nokudabuka kwezembozo zamalensi kungenye yezizathu eziyinhloko zokushintsha izibuko. Namuhla, ake sifunde ngolwazi oluhlobene nezembozo zamalensi.
Ngaphambi kokuba kube khona amalensi e-resin, amalensi engilazi yiwona kuphela ayetholakala emakethe. Amalensi engilazi anezinzuzo ezifana ne-refractive index ephezulu, ukudlulisa ukukhanya okuphezulu, kanye nokuqina okuphezulu, kodwa futhi anamaphutha: kulula ukuwaphula, asinda, futhi awaphephile, phakathi kokunye.
Ukuze kulungiswe ukushiyeka kwamalensi engilazi, abakhiqizi baye bacwaninga futhi bathuthukisa izinto ezahlukahlukene bezama ukufaka esikhundleni sengilazi ukuze kukhiqizwe amalensi. Kodwa-ke, lezi zindlela azizange zibe zinhle kakhulu—into ngayinye inezinzuzo nezinkinga zayo, okwenza kube nzima ukufeza ukusebenza okulinganiselayo okumboza zonke izidingo. Lokhu kufaka phakathi ngisho namalensi e-resin (izinto ze-resin) asetshenziswa namuhla.
Kumalensi e-resin anamuhla, ukumboza kuyinqubo ebalulekile.Izinto ze-resin nazo zinezigaba eziningi, njenge-MR-7, MR-8, CR-39, PC, kanye ne-NK-55-C.Kukhona nezinye izinto eziningi ze-resin, ngayinye inezici ezihlukile kancane. Kungakhathaliseki ukuthi ilensi yengilazi noma ilensi ye-resin, lapho ukukhanya kudlula ebusweni belensi, kwenzeka izinto eziningana ezibonakalayo: ukubonakalisa, ukufiphaza, ukumuncwa, ukuhlakazeka, kanye nokudluliselwa.
Isimbozo Esingabonisi Ukukhanya
Ngaphambi kokuba ukukhanya kufinyelele ebusweni belensi, amandla alo okukhanya angu-100%. Kodwa-ke, uma kuphuma ku-interface yangemuva yelensi bese kungena esweni lomuntu, amandla okukhanya awasasekho angu-100%. Uma iphesenti lamandla okukhanya liphezulu, kulapho ukuhanjiswa kokukhanya kuba ngcono khona, futhi ikhwalithi yesithombe kanye nesisombululo kuphakeme.
Ngohlobo oluthile lwezinto zelensi, ukunciphisa ukulahleka kokukhanya kuyindlela evamile yokuthuthukisa ukuhanjiswa kokukhanya. Uma ukukhanya kukhanya kakhulu, ukuhanjiswa kokukhanya kwelensi kwehla, futhi ikhwalithi yokuthwebula izithombe iba mpofu. Ngakho-ke, ukuvimbela ukubonakaliswa sekuyinkinga ebalulekile okumele ixazululwe ngamalensi e-resin—futhi yile ndlela ukugqoka okuvimbela ukubonakaliswa (okwaziwa nangokuthi amafilimu okuvimbela ukubonakaliswa noma ukugqoka kwe-AR) okusetshenziswa ngayo kumalensi (ekuqaleni, ukugqoka okuvimbela ukubonakaliswa kwakusetshenziswa kumalensi athile okukhanya).
Izembozo ezivimbela ukukhanya zisebenzisa isimiso sokuphazamiseka. Zithola ubudlelwano phakathi kokukhanya okunamandla kwesendlalelo esivimbela ukukhanya selensi embozwe kanye nezici ezifana nobude bokukhanya okubangelwa ukukhanya, ukujiya kwezembozo, inkomba yokugqama kwezembozo, kanye nenkomba yokugqama kwelensi. Lo mklamo ubangela ukuthi imisebe yokukhanya edlula embezweni ihlukane, kunciphisa ukulahleka kwamandla okukhanya ebusweni belensi futhi kuthuthukise ikhwalithi yesithombe kanye nesisombululo.
Iningi lezingubo ezivimbela ukukhanya zenziwe ngama-oxide ensimbi ahlanzekile kakhulu njenge-titanium oxide ne-cobalt oxide. Lezi zinto zifakwa ebusweni belensi ngenqubo yokuhwamuka (i-vacuum evaporation coating) ukuze kufezwe umphumela ophumelelayo wokulwa nokukhanya. Izinsalela zivame ukuhlala ngemva kwenqubo yokumboza okuvimbela ukukhanya, futhi iningi lalezi zingubo libonisa umbala oluhlaza okotshani.
Ngokuyisisekelo, umbala wezingubo ezivimbela ukukhanya ungalawulwa—isibonelo, zingakhiqizwa njengezingubo eziluhlaza okwesibhakabhaka, izingubo eziluhlaza okwesibhakabhaka, izingubo ezinsomi, izingubo ezimpunga, njll. Izingubo ezinemibala ehlukene ziyahlukahluka ngokwezinqubo zazo zokukhiqiza. Thatha izingubo eziluhlaza okwesibhakabhaka njengesibonelo: izingubo eziluhlaza okwesibhakabhaka zidinga ukulawula ukukhanya okuphansi, okwenza inqubo yazo yokumboza ibe nzima kakhulu kunezo zokugqoka eziluhlaza. Kodwa-ke, umehluko ekudluliseleni kokukhanya phakathi kwezingubo eziluhlaza okwesibhakabhaka nezembatho eziluhlaza ungase ube ngaphansi kuka-1%.
Emikhiqizweni yelensi, izembozo eziluhlaza okwesibhakabhaka zisetshenziswa kakhulu kumalensi aphakathi kuya kwaphezulu. Ngokuyisisekelo, izembozo eziluhlaza okwesibhakabhaka zinokudluliswa kokukhanya okuphezulu kunezembozo eziluhlaza (kufanele kuqashelwe ukuthi lokhu "ngokuyisisekelo"). Lokhu kungenxa yokuthi ukukhanya kuyinhlanganisela yamagagasi anama-wavelength ahlukene, futhi izindawo zokuthatha izithombe zama-wavelength ahlukene ku-retina ziyahlukahluka. Ngaphansi kwezimo ezijwayelekile, ukukhanya okuphuzi-okuluhlaza okwesibhakabhaka kuthathwa isithombe ngqo ku-retina, futhi ukukhanya okuluhlaza kunikela kakhulu olwazini olubonakalayo—ngakho-ke, iso lomuntu lizwela kakhulu ekukhanyeni okuluhlaza.
