Abafundi abaninzi kufuneka banxibe iindondo ngenxa yezizathu ezifana nokuncipha kwamehlo.Phambi kweevenkile zeglasi kuyo yonke indawo esitratweni, abafundi bafanele bakhethe kwaye bathenge njani amashishini kunye neemveliso ukuze batshatise iiglasi ezizilungeleyo?
Njengoko sonke siyazi, iiglasi ezingafanelekanga aziphumeleli nje ukulungisa umbono, kodwa zingabangela umonakalo emehlweni.Ke, zeziphi iingxaki abafundi abafanele banikele ingqalelo kuzo xa bethelekisa iindondo?
Ngoko ke, uviwo olucwangcisiweyo lwe-ophthalmic kufuneka luqhutywe phambi kwe-optometry.Kuyimfuneko kakhulu ukwahlula phakathi kwe-myopia yokwenyani kunye ne-myopia yobuxoki.
Inyathelo lesibini Ukukhetha indawo
Iiglasi kufuneka ziye kwisibhedlele esiqhelekileyo okanye kwivenkile ethembekileyo yeglasi.Ungazami ukuba nexabiso eliphantsi okanye lula.Jonga ukuba ishishini leeglasi lifumene ilayisenisi yokuvelisa iimveliso zeglasi.
Ingaba izixhobo ze-Optometry kunye nezixhobo zokuvavanya zeshishini leeglasi zinamanqaku afanelekileyo, i-optometry, ingaba abasebenzi bemveliso banezatifikethi, nokuba iiglasi zinamanqaku afanelekileyo (iziqinisekiso), njl.
Emva kwayo yonke loo nto, "izatifikethi ezine" eziphethwe ngamashishini eeglasi zisisiseko sokuqinisekisa umgangatho weeglasi.
Inyathelo lesithathu Ingqwalasela ekulungiseleleni iiglasi
Iiglasi kufuneka zilungiswe nge-Optometry, ukunxitywa kwelingo kunye nezinye iinkqubo.
Ngokweemfuno zogqirha, i-mydriasis optometry kufuneka yenziwe xa kuyimfuneko, ngakumbi kubantwana abancinci kunye nabaqalayo.Emva kwe-Optometry, cela iphepha le-Optometry.
Ekubeni i-Optometry ichaphazeleka lula yimvakalelo kunye nemeko yomzimba, kufuneka yenziwe kabini kwiintsuku ezimbalwa ukufezekisa iziphumo zesayensi kunye nezichanekileyo.
Inyathelo lesine Izinto zokukhetha iiglasi
Ngokuqhelekileyo, iilensi zokubukela zihlulwe zibe yi-resin, iglasi kunye nekristale.Zombini iilensi kunye nezakhelo kufuneka zibe "nobomi beshelufu".Ukuba i-lens, isakhelo kunye nefreyimu zizinto ezingeniswa kwamanye amazwe, isiqinisekiso sokuhlolwa kwempahla engaphandle siya kubonelelwa.
Iilensi zeResin zithandwa kakhulu ngabafundi ngenxa yobunzima bazo, kodwa iimfuno zokulondolozwa zikwaphezulu.
Umzekelo, xa iqondo lobushushu lingaphezulu kwe-60 ℃, iilensi ziya konakaliswa kwaye zibe mfiliba ngenxa yamazinga ahlukeneyo okwandisa umaleko ngamnye kubushushu obuphezulu, kwaye i-coefficient yokumelana nokunxiba isezantsi kakhulu kunelensi zeglasi.Ngoko ke, abathengi kufuneka banikele ingqalelo ekukhuselweni kweelensi xa benxibe ngamaxesha aqhelekileyo.
Inyathelo lesihlanu Emva kokuthenga iindondo
Emva kokuthenga iiglasi, kufuneka ucele iyunithi yokuthengisa iziqinisekiso ezifana ne-odolo yokulungiswa kweeglasi, i-invoyisi kunye nokuzinikela emva kokuthengisa, ukuze ukwazi ukukhusela amalungelo akho asemthethweni kunye nomdla xa kukho iingxaki kwixesha elizayo.
Ukuba kufunyaniswe ukuba kusekho iimpendulo ezingathandekiyo ngaphezulu kweveki enye emva kokunxiba iiglasi, abathengi kufuneka badibane nogqirha wamehlo okanye ingcali ngexesha.
Ukuba umntwana ukhangelekile emva kokuxilongwa, abazali akufanele bakhathazeke kakhulu.Bamele bakhethe i-lens efanelekileyo kwaye banxibe iiglasi kwangethuba, ukwenzela ukuba ukufumanisa kwangaphambili kunye nonyango lwakwangoko lunokufumana iziphumo ezingcono.
Ilensi yeConvox Myopia (iMyovox) ithatha itekhnoloji yokuphelisa ujoliso lweperipheral ukucothisa inkqubela phambili ye-myopia, ekhuselekileyo, enganyangekiyo kwimpembelelo, engeyoethe-ethe, ukuqina okuqinileyo, ngokwesayensi ukuthintela ukukhanya okuluhlaza kumonakalo wedijithali, funda ukudinwa kunye namehlo akhululekile, kunye nesizukulwana esitsha. yoyilo lwe-asymmetric ukukhusela ngokupheleleyo amehlo abantwana.
