Basesitokisini sezidakamizwa, isitolo sezincwadi, ngisho nesitolo se-dollar. Eqinisweni, kubonakala sengathi noma yikuphi lapho kufundwa khona, ungathola izibuko zokufunda ezingabizi nge-over-the-counter (OTC). Kodwa kuphephile kangakanani lezi zindwangu ezikhiqizwa ngobuningi, uma kuqhathaniswa nezibuko zokugqoka ezingaba nezindleko kaningi? Nakhu ukubuka ukuthi yikuphi isaphulelo noma ukulungiswa okwenziwe okwenziwe izibuko zokufunda eziklanyelwe ukwenza, nokuthi ngabe kufanele uzame.
Iso eliguga
Iningi labantu lihlangabezana nezinguquko ezithile embonweni wazo njengoba zikhula. Ukushintshwa okujwayelekile kakhulu futhi okuphawulekayo kubizwa ngokuhleka ngokuthi "i-short arm syndrome", noma isidingo sokubamba izinto kude kakhulu ngenxa yokunciphisa ikhono lokugxila ezintweni eziseduze. Ngokusemthethweni, yaziwa ngokuthi i- presbyopia .
I-Presbyopia yenzeka ngenxa yokuqina kwesilensi iso, ishiya ilensi engakwazi ukugoba ukuze igxile, futhi ngenxa yezinguquko emisipha elawula ilensi.
Njengoba ungase uthole, noma yini eyenza ukuthi ukuphrinta okuhle kukhule kakhulu kuzosiza-kungakhathaliseki ukuthi kuyiglasi lokudala elidala, noma kungena ku-camera yakho ye-smart phone. Ukunika amandla amandla ekufuneni izibuko kwenza izinto ezincane namazwi kukhasi libukeke likhulu ukuze bakwazi ukubona.
Ama-Eye Glasslass vs. Preschool-Made
Izibuko zokubhalisa zingalungisa izinkinga ezimbalwa ezihlukene, kufaka phakathi ukubona okuncane (ubunzima ukubukela izinto ezikude), ukubhekwa phambili (ukukhathazeka ukubona izinto eziseduze), kanye ne- astigmatism .
I-Astigmatism iyenzeka lapho phambili kweso libunjwa njengebhola lebhola lebhola lebhola lezinyawo, futhi lingabangela izithombe eziphambene. Ngaphezu kwalokho, ngoba izibuko zokugqoka zenzelwe wena ngqo, izikhungo zokukhanya zensimbi ngayinye (lapho i-lens izokwenza khona ngokuphumelelayo) zihambelana nezikhungo zabanye abafundi bakho.
Abafundi abalungile, ngokuphambene, bakhiqizwa kakhulu futhi baklanyelwe ngenhloso eyodwa kuphela-ukukhulisa isithombe phambi kwakho. Ngeke balungise ukubuka phambili noma i-astigmatism.
Ingabe Abafundi Abaningi Bokubala Kuphephile?
U-Natalie Hutchings, uprofesa ohlangene e-University of Waterloo's Optometry kanye neScience Science, uthi ukufunda izibuko ezikhiqizwa ngobuningi ngeke kuwenze ukuba ungaboni, kodwa kungabangela izinkinga kwabanye abantu.
"Kubantu abadala asebekhulile, lezi zibuko zokufunda zizoba ngcono, futhi ngeke zilimaze ngokungenakuphikisa amehlo akho," esho. "Uma ngabe imithi yakho ayinamandla kakhulu, futhi uyisebenzisela isikhathi esifushane nje-ukufunda ilebula esheshayo esitolo sokudla, isibonelo-lezi ziglasi ezingabizi kufanele zingalimazi."
Kodwa uHutchings uyaphawula ukuthi uma unenkinga yamehlo noma ikhanda, kufanele ube nodokotela wakho wezandla ahlole izibuko zakho zokufunda. Ucaphuna ucwaningo oluvela eNyuvesi yaseCincinnati ehlola abafundi abaphakamisa abantu abaningi. Ethunyelwe ku-Association for Research ku-Vision and Ophthalmology (ARVO) ingqungquthela yaminyaka yonke ngoMeyi 2013, isifundo esingashicilelwa sasihlola ama-160 wabili abafundi abalungile. Cishe ingxenye yesine yezimbili (amaphesenti angu-24) atholakala ukuthi anezikhungo zokukhanya ezivezwe ngamamitha ayizi-2, okwenza abacwaningi uConstance West noDavid Hunter baphumelele kungaholela ekutheni i-eyestrain ibe nombono kabili kubantu abadala abaningi.
I-West ne-Hunter icebisa ochwepheshe be-eye ukuba balinganise izikhungo ze-optical nokuphakamisa amandla ezigungwini ze-OTC zeziguli zabo.
Amathiphu Ukusetshenziswa Okuphephile KweziLilo Zokufunda Ezilungiselelwe
UNatalie Hutchings unikeza amathiphu alandelayo ngokusetshenziswa okuphephile kwezibuko zokufunda ezilungiselelwe:
- Khetha amandla kuphela okuvumela ukuthi ufunde okuthile endaweni ekhululekile. Ukuqina akusilo kangcono kakhulu.
- Hlola izibuko ze-bubbles, amagagasi, noma ezinye iziphazamiso ezingase ziphazamise amehlo akho.
- Ungasebenzisi ama-over-the-counter abafundi ngokusebenza kukhompyutheni; uhlala ngaphezulu kwesikrini kunokwenza kusukela encwadini noma kumagazini.
- Sebenzisa laba bafundi imisebenzi esheshayo kuphela, njengokufunda ilebula esitolo.
- Uma uhlakulela ikhanda, uthathe izibuko zakho zesaphulelo kudokotela wezilanga ukuze abafundi bahlolwe.
Okokugcina, musa ukuhlola iso njalo njalo noma ngabe laba bafundi be-OTC basebenzela wena. Ubuciko bokubukeka yisici esisodwa sombono wokuthi i-ophthalmologist noma i-optometrist izohlola. Bangakwazi futhi ukuhlonza izinkinga ezinamandla ezinjenge-sikashukela ne- retinal detachment , ezinkathini zokuqala lapho kungase kube khona izimpawu ezibonakalayo.
