Ukufakwa kwelensi eqhubekayo ibisoloko ingumba oshushu kwishishini le-Optometry.Isizathu sokuba i-lens eqhubekayo ihluke kwi-lens eyodwa yokukhanya kukuba iperi ye-lens ehamba phambili inokusombulula ingxaki yabantu abadala inokubona ngokucacileyo ukusuka kude, phakathi nakufuphi, ekulungele kakhulu, intle kwaye inokugubungela iminyaka.Ngoko kutheni loo mveliso "egqwesileyo" inezinga lokungena kuphela kwi-1.4% e-China, kodwa ngaphezu kwe-48% kumazwe aphuhlileyo?Ngaba kungenxa yexabiso?Ngokucacileyo akunjalo, i-xiaobian ikholelwa ukuba izinga lempumelelo longqamaniso oluqhubekayo linxulumene ngokusondeleyo.
Izinga lempumelelo yokufakwa okuqhubelekayo iphenjelelwa zizinto ezininzi, ezinjengolindelo lomthengi, ubaxo lwemveliso, ukuchaneka kwedatha (umyalelo we-Optometry, umgama womfundi, ukuphakama komfundi, i-ADD, ukukhetha itshaneli), ukhetho lwefreyimu yelensi, njl. njl. Oogqirha bamehlo abaninzi emsebenzini wabo baya kunzima nokukhethwa kwejelo.Namhlanje, uXiaobian uya kukwabelana nawe ngendlela yokukhetha itshaneli eqhubekayo.
Emva kokubonisana nolunye ulwazi kunye nokubuza oogqirha bamehlo abanamava, bonke bavumile ukuba akufuneki sichaze ukuba loluphi uhlobo lwesitishi esilungele abathengi kuphela ukusuka "kubude besakhelo", kodwa kufuneka sithathele ingqalelo ezi zinto zilandelayo:
1. Ubudala bomthengi
Ngokubanzi, abantu abadala abaphakathi nabadala abangaphantsi kweminyaka engama-55 banokukhetha zombini iitshaneli ezinde nezimfutshane, kuba i-ADD ayinkulu kakhulu, kwaye ukuguquguquka kukwalungile.Ukuba i-ADD inkulu kune +2.00, kungcono ukhethe umjelo omde.
2. Ziqhelanise nokuma kokufunda
Abathengi banxiba iiglasi ukuze babone izinto, ukuba bajwayele ukuhamba kwamehlo, bengaqhelanga ukuhamba kwentloko, kucetyiswa ukuba iziteshi ezide kunye ezimfutshane zinokubakho.Ukuba usetyenziselwa ukuhambisa intloko, ungasetyenziselwa ukuhambisa amehlo, kuyacetyiswa ukuba ukhethe umjelo omfutshane.
3. Ukuziqhelanisa nomthengi
Ukuba ukulungelelaniswa komelele, imijelo emide kunye nemfutshane ingaba.Ukuba ukulungelelaniswa kubi, kuyacetyiswa ukuba ukhethe umjelo omfutshane
4. YENGEZELA inombolo yefotometric (ADD)
I-ADD ngaphakathi kwe-2.00d, zombini iziteshi ezide kunye nezifutshane zamkelekile;Ukuba i-ADD inkulu kuno + 2.00d, khetha isitishi eside
5. Ubude bomgca othe nkqo wesakhelo
Khetha itshaneli emfutshane yezakhelo ezincinci (28-32mm) kunye netshaneli emide yezakhelo ezinkulu (32-35mm).Akukhuthazwa ukuba ukhethe iifreyimu ezinobude bomgca othe nkqo ngaphakathi kwe-26mm okanye ngaphezulu kwe-38mm, ngakumbi ukuba iifreyimu ezinobukhulu obukhulu zikhethwa kwiitshaneli ezimfutshane, ukwenzela ukuphepha ukungahambi kakuhle kunye nezikhalazo.
6. Ukuthotywa kwamehlo
Xa sikhetha amajelo, kufuneka siqwalasele ukwehla kwamehlo omthengi kunye nezinye iingxaki.Ngokwethiyori, umthengi emdala, kokukhona ukwehla kuya kuba buthathaka, kwaye ubungakanani bedigri yokongeza i-ADD sanda ngokukhula kweminyaka.
Ke ngoko, nokuba abathengi abalupheleyo bane-ADD ephezulu, kodwa amandla okwehla kwamehlo afunyaniswa angonelanga okanye awahlali ngokwaneleyo emva kovavanyo, iimpawu zokungakwazi ukufikelela kwindawo ekufutshane yokukhanya kunye nokubona ukufiphala okukufutshane kunokubakho. kwenzeka ukuba bakhetha itshaneli elide okanye umjelo oqhelekileyo.Kule meko, kukwacetyiswa ukuba ukhethe itshaneli emfutshane.
