Izibuko zamehlo, into eqanjiwe ephawulekayo eye yashintsha ukuphila kwezigidi, inomlando ocebile nothakazelisayo owathatha amakhulu eminyaka. Kusukela ekuqaleni kwabo okuphansi kuya ekusungulweni kwesimanjemanje, ake siqale uhambo olubanzi ngokuvela kwezibuko zamehlo.
Imvelaphi Yasendulo
Izimpande zezibuko zamehlo zingalandelelwa emuva empucukweni yasendulo. ERoma lasendulo, cishe ngekhulu lokuqala AD, ukusetshenziswa kwengilazi yokukhulisa umbono kwabhalwa phansi. Lolu hlobo lokuqala lokukhuliswa lwabeka isisekelo sokwakhiwa kwezibuko zamehlo.
Ukuphumelela Kwenkathi Ephakathi
Kwakuphakathi nenkathi ephakathi lapho izibuko zamehlo zaqala khona ukwakheka ngendlela esizazi ngayo namuhla. Ngekhulu le-13, indela yase-Italy okuthiwa uSalvino D'Armate kuthiwa yasungula izibuko zamehlo zokuqala ezigqokekayo. Lezi zibuko zakuqala zazinamalensi amabili ayi-convex ahlanganiswe uhlaka olubekwe phezu kwebhuloho lekhala. Ngokuyinhloko zazisetshenziselwa ukulungisa ukubona kude, ukukhubazeka okuvamile kokubona.
Intuthuko ye-Renaissance
Inkathi yeRenaissance yabona intuthuko enkulu emkhakheni wezokubona kanye nezibuko zamehlo. Ngekhulu le-16, kwaqalwa ama-lens aconcave ukuze alungise ukubona eduze. Lokhu kuphumelela kwavumela abantu abanokukhubazeka okuhlukile kokubona ukuthi bahlomule ngezibuko zamehlo.
Phakathi nalesi sikhathi, izibuko zamehlo nazo zaba isitatimende semfashini phakathi kwe-elite. Amafreyimu enziwe ngezinsimbi eziyigugu, njengegolide nesiliva, ahlotshiswe ngemiklamo eyinkimbinkimbi, aba uphawu lwengcebo nesimo.
Uguquko Lwezimboni kanye Nokukhiqiza Okuningi
INguquko Yezimboni ngekhulu le-18 yashintsha ukukhiqizwa kwezibuko zamehlo. Ngokufika kwemishini nezindlela zokukhiqiza ngobuningi, izibuko zamehlo zathengeka kakhulu futhi zafinyeleleka kubantu abaningi. Ukwethulwa kwamafreyimu ensimbi kanye nekhono lokukhiqiza amalensi anemimo nosayizi abahlukahlukene kwanweba nakakhulu izinketho ezitholakalayo kwabagqoka izibuko zamehlo.
Ukuphakama Kwe-Optometry
Ngekhulu le-19, umkhakha we-Optometry wavela, ugxile kwisayensi yokulungiswa kombono. Odokotela bamehlo babambe iqhaza elibalulekile ekuchazeni nasekufakeni izibuko zamehlo, baqinisekisa ukuthi abantu bathola amalensi afanele ngezidingo zabo ezibonakalayo. Lokhu kwenziwa ngobungcweti kokufakwa kwezibuko zamehlo kanye nencwadi kadokotela kwaphawula ingqopha-mlando ebalulekile ekuthuthukisweni kwezibuko zamehlo.
Izindlela Ezintsha Zanamuhla
Ikhulu lama-20 laveza izinto eziningi ezintsha ezingilazini zamehlo. Ekuqaleni kwawo-1900, ukwethulwa kwamafreyimu epulasitiki kwaguqula imboni. Lawa mafreyimu angasindi futhi aqinile athathe indawo yamafreyimu ensimbi avamile, anikeza ukunethezeka okukhulu nezinketho zesitayela.
Maphakathi nekhulu lama-20, ukuthuthukiswa kwamalensi aqhubekayo kunikeze inguquko engenamthungo phakathi kwezindawo zokubona ezihlukene, okuqeda isidingo samapheya amaningi ezingilazi. Ukwengeza, ukusetshenziswa kwezinto ezithuthukisiwe zamalensi, njenge-polycarbonate namapulasitiki anenkomba ephezulu, kubangele amalensi azacile futhi alula, athuthukisa kokubili ukunethezeka nobuhle.
Amalensi Okuxhumana kanye Nokuhlinzwa Kwe-Laser
Ingxenye yokugcina yekhulu lama-20 yabona ukwanda kwezinye izindlela zokulungisa ukubona, njengamalensi okuxhumana kanye nokuhlinzwa kwamehlo nge-laser. Amalensi okuxhumana anikeze inketho engaphazamisi kulabo abafisa ukugwema ukugqoka izibuko zamehlo. Ngakolunye uhlangothi, ukuhlinzwa kwamehlo nge-laser, kwanikeza ikhambi elihlala njalo lezinkinga zokubona ngokulungisa kabusha i-cornea.
Nakuba lezi zindlela ezihlukile zathola ukuduma, izibuko zamehlo zahlala ziyindlela esetshenziswa kakhulu futhi elula yokulungisa umbono ngenxa yokusebenziseka kwazo kalula, ukufinyeleleka kwazo, kanye nemvelo engahlanyisi.
Amathuba Esikhathi esizayo
Njengoba sibheke esikhathini esizayo, imboni yezibuko zamehlo iyaqhubeka nokuvela. Ukuhlanganiswa kobuchwepheshe ezingilazini zamehlo kuya ngokuya kuvame. Izibuko ezihlakaniphile, ezihlonyiswe ngamakhono angokoqobo athuthukisiwe, ziyathuthukiswa ukuze kuthuthukiswe izimpilo zethu zansuku zonke, ezinikeza izici ezifana nokuboniswa kolwazi lwesikhathi sangempela nokuxhumana okungenazandla.
Intuthuko yesayensi yezinto ezibonakalayo ingase iholele ekwakhiweni kwamafreyimu alula nakakhulu futhi ahlala isikhathi eside, okwenza izibuko zamehlo zikhululeke nakakhulu ukuzigqoka. Ukwengeza, ukusetshenziswa kwe-nanotechnology kubambe amandla okuzilungisa amalensi azivumelanisa ngokuzenzakalelayo nezimo zokukhanya ezishintshayo, anikeze umbono ofanele ngaso sonke isikhathi.
Sengiphetha, ukuvela kwezibuko zamehlo kuwubufakazi bokuqanjwa kabusha kwabantu kanye nesifiso sokuthuthukisa okuhlangenwe nakho kwethu okubonakalayo. Kusukela emisuka yazo yasendulo kuya entuthukweni yanamuhla, izibuko zamehlo ziye zavela kude. Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela kuphela okunye ukuthuthuka okuzothuthukisa umbono wethu futhi kuthuthukise izimpilo zezigidi emhlabeni wonke.
