Imicimbi efuna ingqalelo
Iglasi ehambelana neeglasi, ubungakanani bezakhelo buyimfuneko xa ukhetha isakhelo. Ububanzi kunye nokuphakama kwesakhelo kufuneka kukhethwe ngokomfundi.
Emva kweglasi enxibe iiglasi, xa ujonga izinto kumacala omabini, unokufumanisa ukuba inkcazo incitshisiwe kwaye into ebonakalayo ibuthathaka, kuyinto eqhelekileyo kakhulu. Ngeli xesha, kufuneka ujike intloko yakho kancinci kwaye uzame ukubona embindini weelensi, kwaye ukungonwabi kuya kunyamalala.
Ukuqhubeka kwe-Dowsours, iiglasi kufuneka zibekwe phantsi kangangoko kunokwenzeka ukusuka kwindawo ephezulu ukuze ubone.
I-④glaucoma, eye yamehlo, isifo esingakhathaliyo, i-hypertures, i-furvical spondylosis kunye nabanye abantu azicetyiswa ukuba zisetyenziswe.
Ngaba ukhe weva ngeeglasi zeZoming? Ukusuka kwiilensi ekugxilwe kuzo, iilensi ze-Bifocal kwaye ngoku iilensi ze -ustifocus ezininzi,
I-lenses ye-multifucus ye-Multifucus iqhubekile isetyenziswa ngokubanzi kwiilensi ze-myopia zolutsha, i-anti-catigueles zabantu abadala kunye neelensi eziqhubekayo kubantu abadala nabadala. Ngaba uyazi kakuhle i-lenses ye-squinocus yenkqubela phambili?
I-01Iinkalo ezintathu ezisebenzayo ze-lenses ye -usus ye -usus
Indawo yokuqala yokusebenza ibekwe kwindawo ephezulu yendawo ekude. Indawo ekude yidanga efunekayo ukubona kude, isetyenziselwe ukubona izinto ezikude.
Indawo yesibini yokusebenza ibekwe kufutshane nomphetho ongezantsi welensi. Indawo yokusondela sisidanga esifunekayo ukuze sibone kufutshane, sisetyenziselwe ukubona izinto ezikufutshane.
Indawo yesithathu esebenzayo yinxalenye ephakathi edibanisa ezi zinto zimbini, ezibizwa ngokuba yiGradial Aream, ngokuthe ngcembe kunye nokuqhubeka nokuyisebenzisa kude kube ngoku.
Ukusuka ngaphandle, iilensi ze-multifocus ezihambelanayo azifani kwiilensi rhoqo.
02Iziphumo ze-lenses ye -ustifocus eqhubekayo
① Iilensi ze-Multifocus ezihambelanayo zenzelwe ukubonelela ngezigulana ngePressopia enendlela yendalo, efanelekileyo nefanelekileyo yokulungiswa. Ukunxiba iilensi zenkqubela phambili kufana nokusebenzisa ikhamera yevidiyo. Iglasi yeglasi inokubona kude kwaye ikufuphi, kunye nezinto eziphakathi. Ke sichaza iilensi eziqhubayo njenge "iilensi ze-zoom", isibini esinye seeglasi silingana neendidi ezininzi zeglasi.
Ukucothisa ukukhathaza okubonakalayo kwaye ulawule izinga lophuhliso lwe-myopia, kodwa ayingabo bonke abakwishumi elivisayo ukuba banxibe iiglasi ezininzi ezihambelanayo, isihlwele silinganiselwe, ilensi inomda, i-les inesiphumo esithile sokuhlengahlengisa abantwana be-i-bilique abantwana .
Qaphela: Njengoko uninzi lwezigulana zinezigulana ezingaphandle kunokuba zingaphandle, inani labantu abalungele ukunxiba iiglasi eziqhubayo ezininzi ukulawula i-myopia ilinganiselwe, i-accounting i-10% kuphela yeMyopia.
③ Iilensi ezihambelanayo nazo zinokusetyenziselwa ukunciphisa ukudinwa okubonakalayo kubantu abancinci kunye nabakwiminyaka eliphakathi. Njengomqolo welizwe, ukudinwa kweliso kwamehlo omncinci kunye naphakathi kweminyaka eli-bald kungaphezulu ngakumbi kwaye kufanelekile ngakumbi. Iilensi ezihambelanayo zinokufana kwiilensi ze-anti-digigue ukunciphisa ukudinwa okubonakalayo kubasebenzisi bekhompyuter, kwaye kunokusetyenziswa njengeelensi zotshintsho ukuqinisekisa ixesha elide, eliphakathi nelikufuphi nexesha elizayo.
03Ukukhetha kweeglasi ze-strolocial shrinal
Iimfuneko zokuLungisa
Kunqande ukukhetha izakhelo ngebhaphu enkulu ye-nasal kuba indawo yeproximal yezakhelo ezinjalo incinci.
Iimfuneko zeZixhobo
Kungcono ukungakhethi ipleyiti kunye ne-tr frems ngaphandle kweepads zempumlo. Kungenxa yokuba umgama weliso elikufutshane wezakhelo zincinci kakhulu (kufuneka igcinwe malunga ne-12mm eqhelekileyo), iliso elikufutshane alinakufikelela kwisikhundla sendawo ephantsi yendawo esetyenziswayo ngesiqhelo, kwaye kunzima ukuhlengahlengisa i-tilt I-angle yeeglasi.
Ubungakanani besicelo
Ukuphakama okuthe nkqo kuyahambelana nomfundi wesakhelo kufuneka ufezekise iimfuno ezichazwe yimveliso, ebaluleke kakhulu okanye ilingane neemfuno zobude be-16mm +. Ukuba kukho iimfuno ezizodwa, kufuneka ubhekise kwiimfuno zelensi ukukhetha ubungakanani obufanelekileyo besakhelo.
Iimfuneko zomsebenzi
Iifreyimu ezinozinzo olulungileyo kufuneka zikhethwe ukuba ziphephe ukusebenza kweeglasi ezichaphazela iimfuno zosetyenziso. Iiglasi zingagcinwa kwi-angle ye-10 ukuya kwi-15 degrees. Ubuso obugobileyo befreyimu kufuneka bungqinelane needima zobuso bobukrelekrele. Ubude, i-radian kunye nokuqina kwesipili kulungele ukunxiba okuqhelekileyo.
