Namuhla, intsha iyanda inomuzwa wokuthi ukugqoka izibuko zefreyimu ezinkulu kakhulu kungenza ubuso bayo bubonakale buncane, okuyimfashini nemfashini. Kodwa-ke, bangase bangaqapheli ukuthi izibuko zefreyimu ezinkulu ngokuvamile zingenye yezizathu zokuwohloka kombono kanye ne-strabismus. Eqinisweni, akuwona wonke umuntu ofanele ukugqoka izibuko zefreyimu ezinkulu kakhulu! Ikakhulukazi kubantu abanebanga elincane le-interpupillary kanye ne-myopia ephezulu!
Amalensi namathiphu okucubungula
1. Iphoyinti eliphakathi nendawo elibonakalayo lawo wonke amalensi kufanele libe maphakathi ngqo nelensi.
2. Ububanzi bezikhala zelensi ngokuvamile buhluka phakathi kuka-70mm-80mm.
3. Ibanga phakathi kwe-interpupillary kwabesifazane abaningi abadala ngokuvamile liphakathi kuka-55mm-65mm, kanti cishe u-60mm yilona elivame kakhulu.
4. Kungakhathaliseki ukuthi usayizi onjani wohlaka, ngesikhathi sokucutshungulwa, indawo ephakathi nendawo yelensi kufanele isuswe ngokufanelekile ukuze ihambisane nebanga le-interpupillary kanye nobude bomfundi.
Amapharamitha amabili abalulekile ekufakweni kwamalensi ama-diopter kanye nebanga le-interpupillary. Lapho ufaka izibuko zozimele ezinkulu, ikakhulukazi ipharamitha yebanga le-interpupillary idinga ukucatshangelwa. Ibanga phakathi kwezikhungo zamalensi amabili kufanele lifane nebanga le-interpupillary; ngaphandle kwalokho, ngisho noma incwadi kadokotela ilungile, ukugqoka izibuko kungase kubangele ukungakhululeki futhi kuthinte umbono.
Izinkinga Ezibangelwa UkugqokaUhlaka OlukhuluIzibuko
Uhlaka lusebenza umsebenzi wokuzinzisa, okuvumela amalensi ukuthi abe sesimweni esifanele ukuze asebenze kahle, ngakho ukuzinza kubalulekile. izibuko zefreyimu ezinkulu, ngenxa yamalensi azo amakhulu kakhulu, zingaba nomthelela othile emehlweni, okuholela ekuphathekeni kabi uma zigqokwe isikhathi eside.
Izibuko zefreyimu ezinkulu kakhulu zingaba nzima, futhi ukuzigqoka isikhathi eside kungacindezela imizwa esebhulohweni lekhala naseduze kwamehlo, kubeka ukucindezela okukhulu emisipha yamehlo futhi kuholele ekukhathaleni kwamehlo. Ukugqoka isikhathi eside kungase kubangele ukuvuvukala kwamehlo, ikhanda elibuhlungu, ububomvu, nokucindezeleka kwamehlo. Ukwengeza, abantu abagqoke izibuko zefreyimu ezinkulu bangathola ukuthi ukubuka phansi noma ukunyakaza kwekhanda kungazelelwe kungabangela izibuko ukuthi zishelele kalula.
Izibuko zefreyimu ezisinda ngokweqile zingaphazamisa ukubukeka kwabantu. Ukugqoka amafreyimu ezingilazi asinda kakhulu kungabangela ukonakala kobuso, ikakhulukazi kuthinte isiphongo, impumulo, nesilevu ngokwezinga elithile. Phakathi nenqubo yokugqoka izibuko, uma umuntu enamehlo amancane, ifreyimu yezibuko ingase icindezele amehlo, ibenze babonakale bebancane; uma umuntu enamehlo amakhulu, amafreyimu ezingilazi asinda kakhulu angenza amehlo abonakale emakhudlwana.
Indaba ye-Interpupillary Distance ngeUhlaka OlukhuluIzibuko
Amalensi amakhulu kakhulu ezingilazi zozimele ezinkulu angenza kube nzima ukuthi isikhungo esibonakalayo siqondane nebanga langempela le-interpupillary yomuntu. Uhlaka olukhulu lwezibuko ngokuvamile lubangela ukuthi isikhungo se-optical samalensi sibe sikhulu kunebanga phakathi kwabafundi, okubangela ukungaboni ngaso linye phakathi kwesikhungo se-optical samalensi kanye nokuma kwabafundi. Lokhu kungahambi kahle kungaholela ezimpawini ezinjengokuncipha kombono, i-strabismus, isiyezi, futhi uma umuntu ezigqoka isikhathi eside, ayanda amathuba okwanda kwe-myopia.
Ukwengeza, kubalulekile ukuqaphela ukuthi amandla e-refractive wezindawo ezahlukene ze-lens awafani. Imvamisa, amandla acwebezelayo maphakathi nelensi angaphansi kancane kunalawo asemkhawulweni welensi. Abafundi bethu bagxila enkabeni yelensi, ngakho-ke ukugqoka izibuko zefreyimu emikhulu njalo kungase kuholele ekutheni izibuko zishelele phansi ngenxa yesisindo sazo. Lokhu kungabangela ukungahambi kahle phakathi kokugxila komfundi kanye nendawo ephakathi kwelensi, okuholela ekuphazamisekeni okubonakalayo kanye nokwehla okuqhubekayo kombono.
Kwenziwa kanjaniChoqa iRubusukuGlassesFi-rame?
1.Okungasindi, ukukhanya kuba ngcono. Uhlaka olulula lunganciphisa ukucindezela ekhaleni, kwenze kube ntofontofo!
2. Ayikhubazeki kalula, ibaluleke kakhulu! Amafreyimu athambekele ekuwohlokeni ayithinti nje kuphela isikhathi sokuphila kodwa futhi anomthelela nomthelela wokulungisa embonweni.
3. Ikhwalithi enhle kakhulu, ebaluleke nakakhulu. Uma uhlaka luyikhwalithi ephansi, luthambekele ekuhlukanisekeni nasekushintsheni umbala, okuthinta ngokuqondile ukuqina kohlaka.
4. Ukufanisa ubuntu, okubaluleke kakhulu. Izici zobuso zawo wonke umuntu ziyahlukahluka, kungakhathaliseki ukuthi ubuso obugcwele noma obuncane, ibhuloho lekhala eliphakeme noma eliphansi, noma i-asymmetry phakathi kwezindlebe nobuso besokunxele nesokudla, okuholela ekugqokeni okungafanele. Ngakho-ke, kubalulekile ukukhetha uhlaka olufanele izici zakho zomuntu siqu.
Izingozi zeGirlsCi-hoosingKukhulu kakhulu GlassesFizinqama
1. Iningi lamantombazane linamabanga amancanyana kunabesilisa, okuholela ekungqubuzaneni phakathi kwamabanga amancane phakathi komfundi emantombazaneni namafreyimu ezingilazi amakhulu, okuholela ezinkingeni ngemva kokucubungula ilensi:
2. Uma ifreyimu inkulu kakhulu futhi ibanga le-interpupillary lilincane, ukukhishwa kwelensi akwanele, okubangela isikhungo sokubona sezingilazi eziqediwe sibe sikhulu kunebanga langempela le-interpupillary, okuholela ekungaphatheki kahle okuhlukahlukene lapho ugqoke.
3. Ngisho noma ibanga le-interpupillary licutshungulwa kahle, ukukhishwa kwelensi nakanjani kuzofinyelela engxenyeni ewugqinsi emaphethelweni, okubangele ukuthi izibuko eziqediwe zibe nzima kakhulu. Lokhu kungase kubangele ukubonakala kwemiphumela ye-prismatic emaphethelweni, kubenze bangakhululeki ukugqoka futhi mhlawumbe kuholele esiyezini nezinye izimpawu.
Iziphakamiso zeFittingKukhulu kakhulu GlassesFizinqama
1. Kubantu abanamadigri amaphakathi ukuya phezulu ephutha le-refractive, ukukhetha amafreyimu amakhulu kakhulu kungase kungayixazululi indaba yamaphethelo amalensi aminyene, kungakhathaliseki ukuthi inkomba ephezulu ye-refractive yamalensi akhethiwe. Ngisho noma idigri ye-myopia iphansi, imiphetho yamalensi isazoba wugqinsi.
2. Uma ukhetha izibuko zozimele ezinkulu kakhulu, kuyatuseka ukuthi ukhethe izinto ezilula njenge-TR90/titanium metal/plastic steel esikhundleni sezinto zamapuleti (ezisinda kakhulu). Imilenze yohlaka akufanele ibe mncane kakhulu, njengoba amafreyimu angaphambili asindayo nangemuva angabangela izibuko ukuthi zishelele phansi njalo.
Wonke umuntu ufuna ukuba nokubukeka okuhle, kodwa sicela ungakhohlwa ukuthi impilo yamehlo iyona ebaluleke kakhulu. Uma ungayinaki inhloso yokulungisa ukubona ngenxa yalokho okubizwa “ngobuhle,” bese ugcine usudala ezinye izifo zamehlo, kuzoba yingozi kakhulu.
Lapho ukhetha amafreyimu wezibuko, ngaphezu kokucabangela ukuma kobuso bakho, izinwele zezinwele, ithoni yesikhumba, njll., kubalulekile ukunaka isimo samehlo akho bese ukhetha amafreyimu afanele wena. Gwema ukukhetha ngokungaboni ozimele abakhulukazi abadumile, njengoba lokhu kungase kuholele ezinkingeni zokubuka ezingadingekile.
