Kwakhiwa nini izibuko zamehlo?
Yize imithombo eminingi eshiwo ukuthi izibuko zamehlo zasungulwa ngo-1317, umbono wokuthi izibuko kungenzeka ukuthi usuvele waqala ukuthi uBenjamin Franklin wasungula izibuko, nalapho enza ama-biforals, lo msunguli odumile awukwazi ukufakwa ekwakheni izibuko zizonke.
Emhlabeni lapho abantu abangama-60% badinga uhlobo oluthile lwamalensi wokulungisa ukubona ngokucacile, kunzima ukuthola isikhathi lapho ama-eyeglasses awona khona.
Yiziphi izinto ezazisetshenziswa ekuqaleni ukwenza izibuko?
Amamodeli we-Conceptual wezibuko abukeka ehlukile kunezingilazi ezinikezwayo ezibonwa namuhla - ngisho namamodeli okuqala ahlukahlukene kusuka kusiko libe ngamasiko.
Abasunguli abehlukene babenemibono yabo yokuthi bangakuthuthukisa kanjani umbono besebenzisa izinto ezithile. Isibonelo, amaRoma asendulo ayazi ukuthi angayenza kanjani ingilazi futhi asebenzise lelo ndaba ukudala inguqulo yazo ye-eyeglasses.
Abasunguli base-Italy basanda kufunda ukuthi iCrystal Crystal ingenziwa i-convex noma i-concave ukuhlinzeka ngosizo oluhlukile lokubuka kulabo abanokulimala okubonakalayo okuhlukile.
Namuhla, ama-eyeglass lens avame ukuba ngopulasitiki noma ingilazi namafreyimu angenziwa ngensimbi, ipulasitiki, izinkuni kanye nezindawo zekhofi (cha, ama-starbucks awathengisi izibuko - okwamanje noma kunjalo).
Ukuvela kwezibuko zamehlo
Izibuko zokuqala zazingezinto eziningi ezilingana - zonke izixazululo, kepha lokho akunjalo nakancane namuhla.
Ngoba abantu banezinhlobo ezahlukene zokukhubazeka okubukwayo -imusiya(Eseduze),i-hyperopia(Ekufeni),I-Astigmatism,I-Amblllopia(Iso elivilaphayo) nokuningi - Ama-lens ahlukene we-eyeglass manje alungisa la maphutha ayelapha.
Lokhu okulandelayo kungenye yezindlela izingilazi ezithuthukiswe futhi zathuthuka ngokuhamba kwesikhathi:
I-BIFOCALS:Ngenkathi amalensi we-convex asiza labo nge-myopia futhiama-concave lensLungisa i-hyperopia ne-presbyopia, kwakungekho sisombululo esisodwa sokusiza labo abahlupheka kuzo zombili izinhlobo zokulimala kombono kuze kube ngu-1784. Ngiyabonga, uBenjamin Franklin!
ITRIFOCALS:Isigamu seminyaka ngemuva kokusungulwa kwezilwane ezibukwayo, ama-TrucAms aqala ukubukwa. Ngo-1827, uJohn Isaac Hawkins wasungula ama-lens asebenzela labo abanempiloPresbyopia, isimo sombono esivame ukushaya ngemuva kweminyaka engu-40. Ama-Presbyopia athinta amandla okwenzayo ukubona phezulu (amamenyu, amakhadi wokupheka, imiyalezo yombhalo).
Ama-lens anama-polarized:U-Edwin H. Land udale ama-polarized lens ngo-1936. Wasebenzisa isihlungi se-polaroid lapho enza izibuko zakhe. I-Polarization inikeza amandla okulwa nokukhanya nokukhulisa induduzo yokubuka. Kulabo abathanda imvelo, ama-lens anama-polarized anikeza indlela yokujabulela izinto ezingaphandle, njengeukufakazanemidlalo yamanzi, ngokwandisa ukubonakala.
Ama-lens athuthukayo:Njenge-BIFOCALS kanye nama-Trifocals,Ama-lens athuthukayoIba namandla amaningi welensi yabantu abanenkinga yokubona ngokucacile emabanga ahlukahlukene. Kodwa-ke, ukuqhubeka kunikeza ukuhlanzeka, ukubheka okungekho emthungo kancane kancane kancane kuthuthuke kumandla ngaphesheya kwelensi ngayinye - ama-goodbye, imigqa!
Amalensi we-PhotoChromic: Ama-PhotoChromic lens, kubuye kwabizwa ngokuthi ama-lens we-transcing, amnyama elangeni futhi ahlale ecaleni ngaphakathi. Amalensi we-PhotoChromic asungulwe ngawo-1960s, kepha athandwa kakhulu kuma-2000s.
I-Blue Light Light Lens:Njengoba amakhompyutha eba amadivaysi athandwayo endlu ngawo-1980s (angabiki ama-TV ngaphambi kwaleyo kanye nama-Smartphones ngemuva), ukusebenzisana kwesikrini sedijithali sekugcwele kakhulu. Ngokuvikela amehlo akho ekukhanyiseni okulimazayo okuluhlaza okwesibhakabhaka okuvela kwizikrini,izibuko ezikhanyayo eziluhlaza okwesibhakabhakakungasiza ukuvikela ubunzima beso ledijithali kanye nokuphazamiseka kumjikelezo wakho wokulala.
Uma unezintshisakalo zokwazi izinhlobo eziningi zamalensi, sicela ubheke amakhasi ethu laphahttps:/www.stock-lens/.
