I-Optometry ayilingani nomyalelo wesibuko
Abantu abaningi bakholelwa ukuthi i-optometry imane “ihlola izinga lokubona eduze” nokuthi uma sebewutholile lo mphumela, bangaqhubeka nokufaka izibuko zamehlo.Kodwa-ke, incwadi kadokotela ye-Optometry "iwumphumela wokulinganisa" kuphela wesimo sokungaboni ngaso linye kwamehlo omuntu ngamunye, futhi ingase ingabi yincwadi kadokotela engcono kakhulu yezibuko.I-Optometry nokufakwa kwengilazi yamehlo kuyizingxenye ezibalulekile zenqubo ephelele, futhi uma kwenziwa ngokwehlukana, kungavela izinkinga.
Ukukhetha amafreyimu engilazi yamehlo kuwumsebenzi wobuchwepheshe.
Isikhathi esiningi, amakhasimende acabangela kuphela "inani lobuhle" lapho ekhetha amafreyimu engilazi yamehlo.Ukube amafreyimu engilazi yamehlo abemane abe isesekeli semfashini njengezingubo, bekuyoqondakala.Kodwa-ke, amafreyimu engilazi yamehlo nawo anomthwalo wemfanelo wokulungisa amaphutha e-refractive.Ngakho-ke, ngaphezu kobuhle, okungenani izici ezintathu kufanele zicatshangelwe:
1. Usayizi wohlaka
Abanye abantu banezindlebe ezimiswe phambili, kanti abanye banezindlebe ezimiswe phambili emuva.Ubude obukhethiwe bamathempeli (izingalo) zezibuko zamehlo buzohluka ngokufanele.Uma amathempeli amade kakhulu noma amafushane kakhulu, angathinta ukutsheka kwe-pantoscopic kanye nebanga le-vertex lezibuko.Yize amawebhusayithi amaningi okuthenga ku-inthanethi ehlinzeka ngobukhulu bezibuko, kunzima ukukhetha ifremu elingana kahle ngaphandle kokuzama yona mathupha.
2. Imithi kadokotela yokufaka ingilazi yamehlo
Umyalelo we-Optometry nokukhetha kwamafreyimu wengilazi yamehlo kuxhumene eduze.Isibonelo, kubantu abanamaphutha aphezulu e-refractive, uma bekhetha amafreyimu angamasayizi amakhulu, ngeke nje amalensi abe awugqinsi futhi asindayo, kodwa futhi kuzoba nzima ukuvumelanisa isikhungo sokubonwayo samalensi nendawo ephakathi yabafundi.Lokhu kungaholela ezimeni ezingezinhle lapho izinkophe zixubha khona kumalensi lapho zicwayiza.
3. Sebenzisa isigcawu nenjongo
Ukukhethwa kozimele kuyahlukahluka kuye ngezidingo ezahlukene.Kubantu abenza imisebenzi evamile yomzimba, amafreyimu anamahlombe angaphakathi aseceleni nezingalo zethempeli ezigobile ukuze alingane kahle ayanconywa.Kulabo abasebenza edeskini isikhathi eside, amafreyimu anama-anti-slip pads namarimu amalensi aphezulu afanelekile.Ngenkathi ushayela, amafreyimu anokubona okubanzi okuzungezile ayakhethwa, futhi amafreyimu amancane angahlinzeka ngokubona okuzungezile okuhle kakhulu.
Konke lokhu kukhathazeka kudinga udokotela wamehlo ochwepheshe ukuba acabangele.Ukufaneleka kozimele besitayela kunganqunywa kuphela ngokuguga kwangempela, kuqinisekiswe ukuthi amapharamitha afaniswa ngokufanele.
Izinkinga ezivela kumapharamitha angafani
Ngaphandle kokuzama nokulinganisa idatha yangempela efanelekile yozimele abakhulu kakhulu, kungaholela ezinkingeni ngokungafani kwebanga le-pupillary (PD).Ukugqoka isikhathi eside kwezibuko ezine-PD engalungile kungaholela emiphumeleni ye-prism, kubangele ukukhathala kwamehlo futhi kusheshise ukuqhubeka kwe-myopia.
Ibanga le-Pupillary (PD) yibanga eliphakathi kwezitho zamehlo.Uma ufaka izibuko, kunezinhlobo ezimbili zezilinganiso ze-PD: ibanga le-PD kanye ne-PD eseduze.I-Distance PD ibhekisela esilinganisweni esithathwa lapho umuntu egxile ekuqondisweni okukude (okungukuthi, ibanga phakathi kwezikhungo zabafundi lapho womabili amehlo ebheke ngqo phambili ebangeni).Eduze kwe-PD (NCD) isilinganiso sebanga phakathi kwezikhungo zabafundi lapho benza umsebenzi oseduze.
Kubalulekile futhi ukucabangela indaba yobude bomfundi uma kuziwa ezingilazini ezinkulu.Kuyaphawuleka ukuthi ukuphakama komfundi wawo womabili amehlo kungase kungabi sezingeni elifanayo.Odokotela bamehlo abanolwazi bazosebenzisa indlela ye-corneal reflection ukuze banqume ukuma okunembile kobude bomfundi.Ukubekezelelana ekuqondeni okuqondile kwamehlo omuntu kuyazwela kakhulu.Uma ukuphakama kwesikhungo se-optical samalensi enziwe kahle kungahambisani nokuphakama komfundi, kungaholela emiphumeleni ye-prism futhi kuholele ekukhathaleni kwamehlo.
Ukunemba Kwe-Optometry
01Ngenxa yezinto ezifana nendawo ye-Optometry kanye nobude besikhathi sokugqoka amalensi okuhlola, kungase kube nokuguquguquka kwemiphumela ye-optometry.Isibonelo, kungaba khona umehluko phakathi kwe-optometry eyenziwa ekuseni nantambama.Ngokuvamile, incwadi kadokotela ntambama ingase ibe phezulu kancane kunasekuseni ngenxa yokukhathala okubonakalayo okunqwabelene usuku lonke.Lapho ukhetha indawo ye-optometry, kubalulekile ukukhetha isikhungo sochwepheshe nesihloniphekile ukuze kuqinisekiswe imiphumela enembe kakhulu nethembekile.
02Ukunemba kwencwadi kadokotela kungahluka ngeso ngalinye.Ngesikhathi senqubo ye-optometry, i-optometry yekhompuyutha ingasebenza njengereferensi, kodwa akufanele neze ibhekwe njengomyalelo wokugcina wezingilazi.Udokotela wamehlo udinga ukubuza kabanzi mayelana nokunethezeka komuntu ogqokile futhi ngokuqhubekayo aqinisekise futhi alinganise amandla ayindilinga (ukubona eduze, ukubona kude) kanye ne-cylindrical (astigmatism) ukuze athole ibhalansi engcono kakhulu futhi alungise kahle i-eksisi ye-astigmatism.
Ukuhlolwa Kwezifo Zamehlo kanye Nokuhlola Umsebenzi Obukwayo
I-Optometry yobungcweti ihilela okungaphezu nje kokunikeza imiyalelo yokubona eduze neyokubona kude.Kuhlanganisa nezivivinyo ezibalulekile ezingakwazi ukwenziwa ku-inthanethi:
① Ukuhlolwa kwamehlo kokuqala: Ukukhipha izifo zamehlo.
② Ukuhlolwa kokusebenza okubonakalayo: Ukuhlolwa kwemisebenzi yokubukwayo yeleveli emithathu kanye nokuhlolwa kwe-ocular kanye nokuhlolwa kokuhlangana.
③ I-Ergonomics yokufakwa kwezingubo zamehlo: Ukutsheka kwe-Pantoscopic, ibanga le-vertex, kanye nokuma kwesikhungo sokubona.
Izilinganiso ezenziwe zaba ngezakho kanye nokwenza ngendlela oyifisayo kudinga ukunquma le miphumela yokuhlolwa.
Imiphumela Ethinta Idatha Yokufaka
Idatha yokufaka izingubo zamehlo eku-inthanethi ihlinzeka ngokuyinhloko ngolwazi lwamaphutha e-refractive (ukubona eduze, ukubona kude) kanye nebanga le-pupillary, elibalulekile ekufakeni izibuko.Nokho, maningi amanye amaphuzu edatha angathinta imiphumela efanelekile, njengendawo yokuma kweso, ukuma kwendlebe, ibanga le-vertex, ukutsheka kwe-pantoscopic, kanye nokuma kwesikhungo sokubona.
Ngokungeziwe kudatha engenhla, ngisho nosayizi wozimele ungaba nomthelela omkhulu emiphumeleni efanelekile.Ukugqoka izibuko ezinkulu kungaholela ekuphumeni kwe-chromatic kanye nemiphumela ye-prism.Lokhu kuyiqiniso ikakhulukazi nge-myopia ephezulu, njengoba amafreyimu amakhulu kakhulu angaholela emaphethelweni amalensi aminyene, adele izinzuzo zamalensi anenkomba ephezulu futhi abangele amazinga aphezulu emithelela ye-prism, okuholela esiyezweni.Ngakho-ke, lapho ukhetha ozimele, kubalulekile ukukhetha ozimele abanamapharamitha afanelekile ngokusekelwe emiphumeleni yokuhlolwa yokulinganisa nokufakwa kwesilingo, kunokugxila kuphela esitayeleni.
Amazinga Ekhwalithi kanye Nokulungiswa Kwangemuva Kokulinganisa
Ekufakeni ama-eyewear aku-inthanethi, lapho izibuko ekugcineni zitholwa ikhasimende, kuyadingeka ukuqinisekisa ukunethezeka kokugqoka futhi uhlole kabusha incwadi kadokotela.Ukulungiswa kwamapayipi ekhala, amathempeli, njll., kufanele kwenziwe ngokusekelwe ekubonisaneni ubuso nobuso.Nakuba izibuko zingase zibonakale zilula, ngisho namaphutha amancane angenza zingakhululeki ukugqoka futhi zibeke engcupheni ikhwalithi yokubuka.Umehluko kudatha ungase ubhebhethekise ukukhathala okubukwayo futhi kube kubi nakakhulu ukubona.
Ekuphetheni
Ipheya lezibuko eliqeqeshiwe alisizi nje kuphela abantu ukuthi basebenze futhi bafunde kangcono kodwa futhi liqinisekisa impilo ebonwayo.Ukufakwa kwezingubo zamehlo ku-inthanethi kunikeza izinzuzo ezinjengokuthengeka, izitayela ezihlukahlukene, kanye nenqubo eyenziwe lula.Nokho, akumelwe nanini sikhohlwe inhloso yokuqala yokufaka izibuko.Izibuko kuphela ezihlangabezana nezindinganiso zempilo yamehlo yilokho esikufisa ngempela.
