Ungazisiza Kanjani Izingane Ukukhetha Ipheya Efanelekayo Yezibuko Zezingane?

Esifundweni esishubile, ukugcinwa kwemikhuba yamehlo ezingane kubaluleke kakhulu ngalesi sikhathi, kodwa ngaphambi kwalokho, kungakhathaliseki ukuthi izingane ezingaboni kahle kakade sezivele zinezibuko ezifanele zona ukuze zibhekane nezinkinga ezihlukahlukene zokukhula nokufunda?

Kubaluleke kakhulu ukuhlola i-optometry ngaphambi kokufaka ingilazi ngayinye. Ukucutshungulwa kwenziwa ngokuvumelana nemingcele efanaibanga le-monocular interpupillary,ukuphakama komfundi we-monocular, i-diopter, indawo ye-axial ye-astigmatism, mpofuthiumehluko ovundlile wephoyinti lezibuko eliphakathi nendawo lezibuko, futhiubudlelwano phakathi kwe-diopter nohlaka. I-Optometry inembile, izibuko zingaba ezifaneleka kakhulu izingane.

Ukwanda kwezinkampani zezingubo zamehlo ngenxa yentuthuko yezobuchwepheshe kanye nokwanda kweziguli ezine-myopia kudida abazali abaningi lapho bekhetha izingubo zamehlo, ikakhulukazi entsheni enamehlo asakhula futhi asakhula. Ukuze kulungiswe umbono ngisho nokuvimbela ukubona, izibuko zibalulekile. Izinkinga ezifana nokukhuphuka okubukhali kwe-myopia zibaluleke kakhulu.

Ngakho ungakhetha kanjani izibuko ezifanela ingane yakho?

◀Mayelana nokukhethwa kohlaka▶

  Ngemuva kwe-optometry ngokucophelela, isinyathelo esilandelayo yizibuko.

Ukukhetha uhlaka akumele kugxile kulokho okuthandwa nguwe kuphela, kodwa kumele kube ngokwesayensi futhi kube nengqondo ngokwencwadi ye-Optometry. Ngokuvamile, i-diopter, i-axis ye-astigmatism, ibanga le-interpupillary, i-engeli yokugqoka izibuko, njll. izocatshangelwa. Odokotela bamehlo abangochwepheshe bazosiza ekukhetheni lezi zici.

① Mayelana nokukhetha kohlaka

Ukukhetha uhlaka akumele kugxile kulokho okuthandwa nguwe kuphela, kodwa kumele kube ngokwesayensi futhi kube nengqondo ngokwencwadi ye-Optometry. Ngokuvamile, i-diopter, i-axis ye-astigmatism, ibanga le-interpupillary, i-engeli yokugqoka izibuko, njll. izocatshangelwa.

② Usayizi wohlaka

Khetha uhlaka lwengane yakho olungeke lube lukhulu kakhulu noma lube luncane kakhulu. Uma ifreyimu inkulu kakhulu, ukugqokwa akuzinzile futhi izibuko zisheleleka kalula. Uma izibuko zishelela phansi, isikhungo sokukhanya selensi sizochezuka phakathi nendawo yomfundi, okuzophazamisa umphumela wokuthwebula. Ngokuhamba kwesikhathi, kungase kuthinte ukujula kwe-myopia. Uma ifreyimu incane kakhulu, umkhawulo womugqa wokubona uzovinjelwa, futhi kuzoba nezindawo ezifile, ezizothinta insimu yombono. Ngakho-ke, zama ukukhetha izibuko ezinefreyimu elinganiselayo, ukubukeka okufanelekile, nokuphakama okufanele ukuthuthukiswa kwebhuloho lekhala, ukuze uqinisekise ukuthi izibuko ngeke zishelele phansi.

③ Izinto zohlaka

Okungasindi, okuphephile, nokunethezeka ukugqoka amaphuzu ayisihluthulelo lapho ukhetha uhlaka lwengane, ukuze kugwenywe ukucindezelwa okubangelwa uhlaka olukhulu kakhulu.

◀Mayelana nokukhetha ilensi▶

① Ukufakwa kwelensi

Ake sikhulume ngokugcotshwa kwelensi kuqala. I-surface coating ye-lens inemisebenzi eminingi. Isibonelo, ingavikela i-lens, ivimbele imihuzuko, ikhulise impilo yesevisi ye-lens; thuthukisa ukudluliswa kokukhanya, futhi ubone izinto ngokucacile; ingavimbela ngokuphumelelayo amanzi namafutha ukuthi anganamatheli ku-lens, okwenza i-lens ibe lula ukuyihlanza. Kunezinhlobo eziningi ze-lens coatings. Ezinganeni, i-anti-wear kanye ne-resistant-resisance coat inganikeza izingane kalula ukufunda, ukuzivocavoca, nokuzijabulisa.

② Impahla yelensi

Amalensi ahlukaniswe ikakhulukazi amalensi engilazi, amalensi eresin, namalensi ePC ngokuya ngezinto zawo. Inketho yokuqala yezibuko zezingane yi-PC lens, eyaziwa nangokuthi i-cosmic lens, enesisindo esincane futhi encane, engakwazi ukukhulula ukucindezela kwamalensi ebhulohweni lekhala. Nakuba ilula futhi izacile, i-Cosmic Film inokumelana nomthelela omuhle, ukuphepha okuphezulu, ukuqina okuqinile futhi akulula ukuphuka. Izingane ziyaphila futhi zikhuthele, ngakho kuyisinqumo esiphelele.

③Umsebenzi welensi

I-lens akufanele inikeze kuphela umbono ocacile futhi okhululekile, kodwa futhi ibe nomphumela omuhle wokulawula i-myopia, ongasiza izingane ukuba zinciphise ukuqhubeka kwe-myopia futhi zinciphise amathuba okuthuthukisa i-myopia ephezulu. Ngenxa yokuthi izingane zisesigabeni sokukhula nokukhula, izinga le-myopia lizokhula unyaka nonyaka ngokukhula.

Uma ufuna ukwazi okwengeziwe mayelana nezitayela zemfashini yezibuko kanye nokubonisana nezimboni, sicela uvakashele iwebhusayithi yethu futhi usithinte noma nini.
