Uninzi lwezinto zinexesha lokusebenzisa okanye ubomi beshelufa, kwaye kunjalo neeglasi. Enyanisweni, xa kuthelekiswa nezinye izinto, iiglasi ziyinto enokutyiwa.
Uphando lufumanise ukuba abantu abaninzi basebenzisa iiglasi ezineresin lens. Phakathi kwabo, i-35.9% yabantu itshintsha iiglasi zabo malunga nesithuba seminyaka emibini, i-29.2% yabantu itshintsha iiglasi zabo rhoqo emva kweminyaka emithathu okanye ngaphezulu, kwaye i-36.4% yabantu ibuyisela kuphela iiglasi zabo xa zigugile.
Ubomi beshelufa yemveliso yeeglasi Iiglasi zenzelwe umntu kwaye zilungelelaniswe ngokweeparameters ezahlukeneyo zamehlo (ezifana ne-diopters, i-binocular vision function, iqondo lolungiso olubonakalayo, njl.njl.) emva kwe-Optometry yenzululwazi echanekileyo, kwaye zenziwe ngokwezifiso ngokudityaniswa kweelensi kunye nezakhelo. . Nangona kunjalo, azinzanga ngokusisigxina. Ngokuhamba kwexesha, ukuhanjiswa kokukhanya, ii-diopters zeelensi, kunye nomgama we-interpupillary, i-pantoscopic tilt, kunye nokugoba komphezulu wefreyimu zonke ziyatshintsha.
Emva kokuphela kobomi benkonzo yeeglasi, kungekhona nje ukuba bangonwabi ukugqoka kunye nokuchaphazela iziphumo ezibonakalayo, kodwa zichaphazela ngqo impilo yombono womthengi.

Izinto ezichaphazela uBomi beNkonzo yeeglasi
Ubomi benkonzo obugqwesileyo beperi yeglasi ziinyanga ezili-12 ukuya kwezili-18. Izinto ezimbini ezibalulekileyo ezichaphazela ubomi benkonzo yeelensi kukuhanjiswa kokukhanya kunye nomyalelo.
Ukuhanjiswa kokukhanya
Makhe siqale sijonge idatha ethile: ukuhanjiswa kokukhanya kweelensi ezintsha ngokuqhelekileyo ngama-98%; emva konyaka omnye, ugqithiso yi-93%; emva kweminyaka emibini, yi-88%. Ukuhanjiswa kokukhanya kweelensi kuncipha ngokuthe ngcembe ngokunyuka kwexesha lokusetyenziswa. Iiglasi zisetyenziswa rhoqo kakhulu, zifuna ukucocwa rhoqo. Uthuli lwangaphandle lunokuphinda lugubungele iilensi, kwaye imikrwelo ngengozi okanye imikrwelo ngexesha lokusetyenziswa kunokukhokelela ekuwohlokeni kokusebenza kwamehlo kweelensi. Ukongeza, iilensi ze-resin ziyakwazi ukufunxa ukukhanya kwe-ultraviolet, kodwa ngenxa yoko, zinokutyheli ngokuguga, ezichaphazela ukuhanjiswa kweelensi.
Umyalelo weOptometric
Ummiselo we-optometric utshintsha minyaka yonke. Ngomahluko kwiminyaka yobudala, indawo ebonakalayo, kunye nobukhulu, imeko ye-refractive yamehlo nayo iyatshintsha. Umyalelo weeglasi awunakuhlangabezana neenguqu kwimeko ye-refractive yamehlo, ngoko ke kuyimfuneko ukuba noviwo olutsha lwe-optometric rhoqo kwiinyanga ezili-12 ukuya kwezi-18. Kufanelekile ukukhankanya ukuba kumazwe aseYurophu naseMelika, ixesha elisemthethweni lomyalelo we-optometric ziinyanga ezili-18.
Kubantu abane-myopia, ukuba ukusetyenziswa kweelensi kudlula "ubomi beshelufu," kunokubangela ukudinwa kwamehlo kwaye kukhawulezise ukuqhubela phambili kwe-myopia ngenxa yokuguga kweelensi kunye nokutshintsha kwimeko ye-refractive yamehlo. Kubomi bemihla ngemihla, kufuneka sigcine kwaye sijonge iilensi zethu rhoqo ukuze sikhusele iiglasi zethu kwaye, kwangaxeshanye, sikhusele amehlo ethu.
Iiglasi zeWaranti yokuphelelwa kweempawu
Ukuba kukho nayiphi na imeko kwezi zilandelayo, kufuneka utshintshe iiglasi zakho ngexesha.
1 I-lens igugile kakhulu
Abanye abantu abakhathali kwaye bathanda ukubeka iiglasi zabo macala onke, okanye ngempazamo bazikrwempa iilensi zabo ngelixa bezilolonga. Ukusetyenziswa kwexesha elide kweeglasi ezineelensi ezigugile kakhulu kunokukhokelela ekuboneni mfiliba kwaye konakalise impilo yombono.
2 Iiglasi zonakele kakhulu
Abakwishumi elivisayo badlamkile yaye badlamkile, yaye iindondo zabo zidla ngokugingqika okanye zinyathelwe ngaphandle kokunikela ingqalelo, nto leyo ebangela ukuba iifreyimu zibe nokonakala. Ngamanye amaxesha iiglasi zize ziwe phantsi kwempumlo, kwaye abantwana baqhubeka benxiba emva kokuzilungisa ngokungaqhelekanga. Abazali kufuneka bajonge iiglasi zabantwana babo yonke imihla ukubona ukuba akukho ngxaki na. Nika ingqalelo ekhethekileyo kwinto yokuba iziko le-optical lens kufuneka lihambelane neziko lomfundi weso. Ukuba ayilungiswanga kakuhle, iya kubangela ukukhathala okubonakalayo, i-strabismus, kunye nokunyuka kombono.
3. Umyalelo weeglasi awuhambelani.
Xa inkoliso yabantwana ingaboni kakuhle kwiindondo zabo, abayi kubaxelela ngoko nangoko abazali babo. Kunoko, baya kukrwaqula okanye baphakamise iindondo zabo ukuze babone, nto leyo eyenza kube nzima kubazali ukuqaphela ngokukhawuleza. Ukujongana nokunyuka ngokukhawuleza komntwana kwi-myopia kunye nokungazinzi kakuhle, kudla ngokufunyanwa ukuba kusemva kwexesha ukulungisa ingxaki kwaye kunokunyusa kuphela umyalelo weeglasi.
Abantwana abanxiba iindondo kufuneka baye kwiziko eliqhelekileyo lokufakela iindondo okanye esibhedlele ukuze kujongwe ukubona kwabo rhoqo (iinyanga ezintathu ukuya kwiinyanga ezintandathu). Kuya kufuneka uhlakulele umkhwa olungileyo wokujonga umbono wakho. Nangona abanye abantwana bekwazi ukubona u-1.0 ngawo omabini amehlo, kusenokwenzeka ukuba iliso elinye linokufikelela ku-1.0 kodwa elinye alikwazi. Kunzima ukubhaqa ngaphandle kokuhlolwa ngenyameko.
Emva kokuba unxibe iiglasi, ngakumbi kubantwana, kufuneka ubeke ingqalelo ekusebenziseni iiglasi. Musa ukulinda de iiglasi zonakaliswe kangangokuba azinakuphinda zisetyenziswe ngaphambi kokuba ubeke ezitsha endaweni yazo. Impilo yombono womntwana wakho yeyona ibalulekileyo.
Indlela Yokunyamekela Iiglasi
1. Musa ukubeka iindondo nesipili sijonge ezantsi.
Beka iiglasi ngecala lesipili phantsi. Ukuba uhambisa ngempazamo iiglasi kwisakhelo, iilensi kusenokwenzeka ukuba zikrwelwe. Ukubeka iiglasi ngeelensi ezijonge phantsi kulula kakhulu ukukrazula iilensi, ezingafanelanga ukulahlekelwa.
2. Musa ukubeka iiglasi zakho kubushushu obuphezulu
Iilensi zanamhlanje zizo zonke iilensi eziqatyiweyo. Iilensi ezigqunyiweyo zinokuthintela ngokufanelekileyo imitha ye-ultraviolet kunye nokwandisa ukuhanjiswa kokukhanya. Uluhlu lwefilimu ye-lens lufakwe phezu kwe-lens. Ngenxa yokuba i-coefficient yokwandiswa koluhlu lwefilimu kunye nesiseko sezinto ezisisiseko zihluke, umgca wefilimu ulula kakhulu ukuqhekeka ngenxa yempembelelo yokushisa okuphezulu, ukuphazamisa ukukhanya okungena kwi-eyeball, kubangela ukukhanya okukhulu kakhulu.
Amacebiso: Iiglasi akufunekanga zishiywe emotweni ehlotyeni, kwaye azinakuthathwa ukuze ziyokuhlamba okanye i-sauna. Kufuneka ukuphephe ukusondela kakhulu kwidangatye elivulekileyo xa upheka okanye ukosa inyama. Ukushisa okuphezulu kuya kubangela ukuba yonke ifilimu ephezu kwendawo ye-lens iqhekeke kwaye ikhutshwe.
3. Zama ukungazisuli iilensi ngelaphu leglasi
Ekunxibeni kwansuku zonke iiglasi, umphezulu welensi uhlala ufunxa uthuli oluninzi (olungabonakali ngeso lenyama). Ukuba usula ngokuthe ngqo i-lens ngelaphu lens ngeli xesha, kufana nokusebenzisa i-sandpaper ukugaya i-lens, kwaye abanye abantu basetyenziselwa ukusebenzisa ilaphu lens kwizangqa. Ukosula iilensi, ezi zonke azilunganga.
Ukuba awunayo imiqathango yokucoca iiglasi zakho okwethutyana, kufuneka usule iilensi ngelaphu lelensi. Kunconywa ukuba usule iilensi ngobumnene kwicala elinye kwaye ungasuli iilensi ngasemva nangaphambili okanye kwizangqa. Umbane we-static uya kubangela ukuba uthuli oluninzi lufunwe phezu kwe-lens, ngoko ke ukosula okomileyo ngelaphu lens kufuneka kugwenywe kangangoko kunokwenzeka.
4. Akukho ukudibana neekhemikhali
Musa ukusebenzisa i-Amway yokucoca ulwelo, ishampu, isepha, umgubo wokuhlamba, okanye isicoci sobumdaka obungaphezulu ukucoca iiglasi (iilensi), njengoko oku kunokubangela ukuba ifilimu yelensi ixobuke kwaye ixobuke.
Ungazicoca ngokwakho iindondo zakho yonke imihla xa ugoduka. Sebenzisa nje amanzi abandayo kunye nesepha yesitya engathathi hlangothi. Faka isicelo sesepha yesitya kumacala omabini e-lens, uze uyisebenzise ngokulinganayo kwizangqa ngeminwe yakho, kwaye uhlambulule ngamanzi ompompo de kungabikho ukuvakalelwa kwegreasy.
Emva kokucoca, kuya kubakho amaconsi amancinci amancinci kumphezulu welensi. Sebenzisa itawuli eyomileyo yephepha ukufunxa amathontsi amanzi (qiniseka ukuba ungayihliki i-lens).
Ukuququmbela
Iiglasi zizinto ezichaneke kakhulu kwaye kulula ukubola, kwaye ukunxiba iindondo zokulungiswa kwe-myopia lukhetho oluqhelekileyo. Ukukhusela iindondo kuthetha ukukhusela amehlo ethu. Sinike isikhokelo sobuchwephesha malunga nokugcinwa kunye nokunyamekela iiglasi, kodwa okona kubaluleke kakhulu, sifuna ukuxelela wonke umntu ukuba iiglasi azikho izinto ezinqabileyo okanye izinto ezihlala zihleli; zizinto ezityiwayo kubomi bethu. Ukuba ufunda oku kwaye ufumanisa ukuba iiglasi zakho azisekho phantsi kwewaranti, nceda ukhumbule ukuzibuyisela endaweni yazo ngexesha elifanelekileyo.
