——Ukuba iilensi zilungile, kutheni uzitshintshe?
——Kuyacaphukisa ukufumana iindondo ezintsha kwaye kuthathe ixesha elide ukuziqhelanisa nazo.
——Ndisabona kakuhle ngezi ndondo, ukuze ndiqhubeke ndizisebenzisa.
Kodwa eneneni, inyaniso inokukumangalisa: eneneni iiglasi “zinobomi obuhlala kwishelufu”!
Xa sithetha ngomjikelo wokusetyenziswa kweeglasi, ungaqala ucinge ngokulahlwa kwemihla ngemihla okanye iilensi zoqhagamshelwano zenyanga. Ubusazi ukuba iiglasi ezichazwe ngugqirha zikwanazo nomjikelo wosetyenziso olulinganiselweyo? Namhlanje, masixoxe ukuba kutheni kubalulekile ukutshintsha rhoqo iiglasi zakho, ngakumbi iilensi.
01 ILens Wear and Tear
Njengenxalenye ephambili yeeglasi, iilensi zinezinto ezichaneke kakhulu "zembonakalo," eziyimfuneko ekugcineni impilo entle yokubona. Nangona kunjalo, ezi mpawu azimi ndawonye; ziphenjelelwa zizinto ezahlukahlukeneyo ezifana nexesha, izinto eziphathekayo nokunxiba.
Ngokuhamba kwexesha, njengoko usebenzisa iilensi zamehlo, ngokuqinisekileyo ziqokelela ukunxiba ngenxa yothuli olusemoyeni, amaqhuma ngengozi, kunye nezinye izizathu. Ukunxiba iilensi ezonakeleyo kunokukhokelela ngokulula kukudinwa okubonakalayo, ukoma, kunye nezinye iimpawu, kwaye kunokwenza kube nzima ukubona kufutshane.
Ngenxa yokuguga okungenakuthinteleka, ukutshintsha iilensi rhoqo kubalulekile ekugcineni iiglasi zikwimeko entle yokubona. Oku akufanele kuthathwe lula!
02 Utshintsho kuLungiso lombono
Nokuba unxibe iindondo, imikhwa engalunganga efana nokusebenza ixesha elide kufutshane nomsebenzi wokubona kunye nokusetyenziswa ngokugqithisileyo kwezixhobo zombane kunokuzenza nzulu iimpazamo zokuphinda zibonakale kwaye zikhokelele ekonyukeni kwamandla kagqirha. Ngaphezu koko, abantu abaselula basoloko bekwincopho yokukhula kwabo ngokwasemzimbeni, bajongana noxinzelelo olukhulu ezifundweni, kwaye basoloko besebenzisa izixhobo zombane, nto leyo ebenza kube lula ukuba batshintshe indlela ababona ngayo.
Ukulungiswa okubonakalayo okubonelelwa ngeelensi kufuneka kuhlaziywe ngokukhawuleza ukuze kuhambelane nesimo sombono wangoku. Kubantu abancinci abane-myopia, kucetyiswa ukuba kuhlolwe i-refractive rhoqo emva kweenyanga ezintathu ukuya kwezintandathu, ngelixa abantu abadala kufuneka babe nenye ukuya kwiminyaka emibini. Ukuba ufumanisa ukuba iiglasi zakho azisafanelanga utshintsho lwakho lwe-refractive, kufuneka ubeke endaweni yazo ngexesha elifanelekileyo.
Iingozi Zokugcina iiglasi zidlule kwiNkulumbuso yazo
Ukukhusela impilo yamehlo ethu, kubalulekile ukutshintsha iindondo njengoko kufuneka. Ukunxiba isibini esifanayo ngokungenasiphelo kunokuba nemiphumo emibi emehlweni. Ukuba iiglasi "zihlala ixesha elide zamkelekile," zinokubangela le miba ilandelayo:
01 Ummiselo ongalungiswanga oKhokelela ekuwohlokeni ngokukhawuleza
Ngokuqhelekileyo, imeko ye-refractive yamehlo iyatshintsha ngokuhamba kwexesha kunye neendawo ezibonakalayo ezahlukeneyo. Naluphi na utshintsho kwiiparameters lunokwenza iiglasi ezifanelekileyo ngaphambili zingafanelekanga. Ukuba iilensi azitshintshi ixesha elide, oku kunokukhokelela ekungahambelani phakathi kweqondo lokulungiswa kombono kunye neemfuno zangempela, ukukhawulezisa ukuqhubela phambili kwempazamo ye-refractive.
02 Ukunxitywa okuMandundu kwiiLensi Ukwenzakalisa Amehlo
Iilensi zinokuguga ngokusetyenziswa okwandisiweyo, okukhokelela ekunciphiseni ukucaca kunye nokuhanjiswa kokukhanya. Ngaphaya koko, imikrwelo kunye nemigangatho eyahlukeneyo yokunxiba inokuchaphazela ukuhanjiswa kokukhanya, kubangele ukufiphala okubonakalayo okubonakalayo, ukudinwa kwamehlo, kwaye kwiimeko ezimandundu, kunokunyusa ukubona kufutshane.
03 iiglasi ezigogekileyo ezichaphazela umbono
Udla ngokubabona abahlobo benxibe iindondo ezigogeke kakhulu—ezigotywe ekubeni zibethwa ngoxa bedlala imidlalo okanye bekrwitshiwe—ukuze bazilungise nje ngokungakhathali baze baqhubeke bezinxiba. Nangona kunjalo, iziko le-optical lens kufuneka lihambelane neziko labafundi; kungenjalo, kunokukhokelela ngokulula kwiimeko ezifana ne-latent strabismus kunye neempawu ezifana nokudinwa okubonakalayo.
Ngaloo ndlela, abantu abaninzi bavakalelwa kukuba imbono yabo izinzile—ukuba logama nje iindondo zisenokonakala, zinokunxitywa kangangeminyaka. Le nkolelo iphosakele. Kungakhathaliseki ukuba luhlobo luni lweeglasi ozinxibayo, ukuxilongwa rhoqo kubalulekile. Ukuba kukho ukungakhululeki, uhlengahlengiso olungexesha okanye ukutshintshwa kufuneka kwenziwe. Ukugcina iiglasi zikwimeko efanelekileyo kubalulekile ukugcina amehlo ethu esempilweni.
