Indlela yokunceda abantwana bakhethe iiglasi ezifanelekileyo zabantwana?

Kwisifundo esinzima, ukugcinwa kweendlela zamehlo zabantwana kubaluleke kakhulu ngeli xesha, kodwa ngaphambi koko, ngaba abantwana abasele bengaboni kakuhle sele beneeglasi ezilungele bona ukujamelana neengxaki ezahlukeneyo zokukhula nokufunda?

Kubaluleke kakhulu ukuya kwi-Optometry phambi kokufaka iperi nganye yeglasi. Ukucubungula kuqhutyelwa ngokweeparamitha ezifanaumgama we-monocular interpupillary,ukuphakama komfundi we-monocular, idiopter, indawo ye-axial ye-astigmatism, nkqokwayeiyantlukwano ethe tyaba ethe tyaba yendawo yokukhanya esembindini yeeglasi, kwayeubudlelwane phakathi kwe-diopter kunye nesakhelo. I-Optometry ichanekile, iiglasi zinokufaneleka ngakumbi kubantwana.

Ukwanda kweenkampani zamehlo ngenxa yenkqubela phambili yetekhnoloji kunye nokunyuka kwabantu abane-myopia kuyababhida abazali abaninzi xa bekhetha iimpahla zamehlo, ngakumbi kulutsha olunamehlo akhula kwaye asakhula. Ukulungisa umbono kunye nokuthintela umbono, iiglasi zibalulekile. Imiba efana nokunyuka ngokukhawuleza kwe-myopia ibaluleke kakhulu.

Unokukhetha njani iiglasi ezilungele umntwana wakho?

◀Malunga nokhetho lwesakhelo▶

  Emva kwe-optometry ngononophelo, inyathelo elilandelayo ziiglasi.

Ukukhetha isakhelo akufanele kugxininise kuphela kwizinto ozikhethayo, kodwa kufuneka kube yinzululwazi kunye nengqiqo ngokuhambelana nomyalelo we-Optometry. Ngokuqhelekileyo, i-diopter, i-axis ye-astigmatism, umgama we-interpupillary, i-angle yokunxiba iiglasi, njl njl. Oogqirha bamehlo abaqeqeshiweyo baya kunceda ukukhetha le miba.

① Malunga nokhetho lwesakhelo

Ukukhetha isakhelo akufanele kugxininise kuphela kwizinto ozikhethayo, kodwa kufuneka kube yinzululwazi kunye nengqiqo ngokuhambelana nomyalelo we-Optometry. Ngokuqhelekileyo, i-diopter, i-axis ye-astigmatism, umgama we-interpupillary, i-angle yokunxiba iiglasi, njl njl.

② Ubungakanani besakhelo

Khetha isakhelo somntwana wakho esingenakuba sikhulu kakhulu okanye sibe sincinci kakhulu. Ukuba isakhelo sikhulu kakhulu, ukunxiba akuzinzile kwaye iiglasi zilula ukuzikhupha. Nje ukuba iiglasi zityibilike ezantsi, i-optical center ye-lens iya kuphambuka kumbindi womfundi, nto leyo eya kuchaphazela umphumo wokucinga. Ngokuhamba kwexesha, kunokuchaphazela ukuqina kwe-myopia. Ukuba isakhelo sincinci kakhulu, umda womgca wokujonga uya kuvalwa, kwaye kuya kuba neendawo ezifileyo, eziza kuchaphazela intsimi yombono. Ngoko ke, zama ukukhetha iiglasi kunye nesakhelo esiphakathi, ukubonakala okufanelekileyo, kunye nokuphakama okufanelekileyo kuphuhliso lwebhuloho yempumlo, ukwenzela ukuba uqinisekise ukuba iiglasi aziyi kuhla.

③ Izinto zesakhelo

Ukukhanya okukhanyayo, okukhuselekileyo, kunye nokukhululeka ukugqoka ngamanqaku aphambili xa ukhetha isakhelo somntwana, ukwenzela ukuba ugweme ukunyanzeliswa okubangelwa yifreyimu engaphezulu.

◀Malunga nokukhetha iilensi▶

① Ukwaleka ilensi

Makhe sithethe ngokugquma ilensi kuqala. Ingubo engaphezulu yelensi inemisebenzi emininzi. Ngokomzekelo, inokukhusela i-lens, ukukhusela imikrwelo, ukwandisa ubomi benkonzo ye-lens; ukuphucula ukuhanjiswa kokukhanya, kwaye ubone izinto ngokucacileyo; inokuthintela ngokufanelekileyo amanzi kunye neoli ekubambeleleni kwi-lens, okwenza i-lens ibe lula ukuyicoca. Kukho iintlobo ezininzi zeelensi zokugquma. Kubantwana, i-anti-wear kunye ne-resistant-resistant coating inokubonelela ngokulula kakhulu kubantwana ukuba bafunde, benze umthambo kunye nokonwabisa.

② imathiriyeli yelensi

Iilensi zohlulwe kakhulu ngokweeglasi zeglasi, iilensi zeresin, kunye nePC lens ngokwemathiriyeli yazo. Ikhetho lokuqala leeglasi zabantwana yi-PC lens, eyaziwa ngokuba yi-cosmic lens, ezinobunzima obuncinci kwaye zincinci, ezinokunciphisa uxinzelelo lweelensi kwibhulorho yempumlo. Nangona ilula kwaye incinci, iFilimu yeCosmic inempembelelo entle yokuchasa, ukhuseleko oluphezulu, ukuqina olomeleleyo kwaye akulula ukuphuka. Abantwana badlamkile kwaye bakhuthele, ngoko lukhetho olugqibeleleyo.

③Umsebenzi weLens

I-lens ayifanele ibonelele nje ngokucacileyo kwaye ikhululekile, kodwa ibe nefuthe elihle lokulawula i-myopia, enokunceda abantwana banciphise ukuqhubeka kwe-myopia kunye nokunciphisa ithuba lokuphuhlisa i-myopia ephezulu. Ngenxa yokuba abantwana bekwinqanaba lokukhula kunye nophuhliso, iqondo le-myopia liya kwanda unyaka nonyaka kunye nobudala.

Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
