Uninzi lwezinto lunexesha lokusetyenziswa okanye ixesha lokuphelelwa, kwaye kunjalo nangeeglasi. Enyanisweni, xa kuthelekiswa nezinye izinto, iiglasi ziyinto esetyenziswa kakhulu.
Uphando lufumanise ukuba uninzi lwabantu basebenzisa iiglasi ezineelensi ze-resin. Phakathi kwabo, ama-35.9% abantu batshintsha iiglasi zabo malunga neminyaka emibini, ama-29.2% abantu batshintsha iiglasi zabo rhoqo emva kweminyaka emithathu nangaphezulu, kwaye ama-36.4% abantu batshintsha iiglasi zabo kuphela xa zigugile.
Ubomi beshelufu yeeglasi Iiglasi zenziwe ngokwezifiso kwaye zilungiselelwe ngokweeparamitha ezahlukeneyo zamehlo (ezifana nee-diopter, umsebenzi wokubona nge-binocular, ubungakanani bokulungiswa kokubona, njl.njl.) emva kwe-optometry yesayensi echanekileyo, kwaye zenziwe ngokwezifiso ngokudityaniswa kweelensi kunye neefreyimu. Nangona kunjalo, azizinzanga ngokusisigxina. Ngokuhamba kwexesha, ukuhanjiswa kokukhanya, ii-diopter zeelensi, kunye nomgama phakathi kwabafundi, ukuthambekela kwe-pantoscopic, kunye nokugoba komphezulu weefreyimu zonke ziyatshintsha.
Emva kokuphelelwa lixesha kwenkonzo yezi glasi, azipheleli nje ekubeni zingonwabi xa zinxitywa kwaye zichaphazela imiphumo yokubona, kodwa zikwachaphazela ngqo impilo yokubona yomthengi.

Izinto Ezichaphazela Ubomi Beenkonzo Zeeglasi
Ubomi obufanelekileyo beglasi ezimbini ziinyanga ezili-12 ukuya kwezili-18. Izinto ezimbini ezibalulekileyo ezichaphazela ubomi beglasi kukudluliselwa kokukhanya kunye nonyango.
Ukuhanjiswa kokukhanya
Masiqale sijonge idatha ethile: ukuhanjiswa kokukhanya kweelensi ezintsha ngokuqhelekileyo yi-98%; emva konyaka omnye, ukuhanjiswa yi-93%; emva kweminyaka emibini, yi-88%. Ukuhanjiswa kokukhanya kweelensi kuncipha kancinci kancinci ngokwanda kwexesha lokusetyenziswa. Iiglasi zisetyenziswa rhoqo, zifuna ukucocwa rhoqo. Uthuli lwangaphandle lunokonakalisa iilensi, kwaye imikrwelo okanye ukukrazuka ngengozi ngexesha lokusetyenziswa kunokukhokelela ekuwohlokeni kokusebenza kweelensi. Ukongeza, iilensi ze-resin zinamandla okufunxa ukukhanya kwe-ultraviolet, kodwa ngenxa yoko, zinokuba tyheli ngokukhula, nto leyo echaphazela ukuhanjiswa kweelensi.
Unyango lwamehlo
Unyango lwamehlo luyatshintsha minyaka le. Ngenxa yokwahluka kweminyaka, indawo yokubona, kunye nobunzima, imeko yokuchacha kwamehlo nayo iyatshintsha. Unyango lweglasi lusenokungahlangabezani notshintsho kwimeko yokuchacha kwamehlo, ngoko ke kuyimfuneko ukuba kwenziwe uhlolo olutsha lwamehlo rhoqo emva kweenyanga ezili-12 ukuya kwezili-18. Kubalulekile ukukhankanya ukuba kumazwe aseYurophu naseMelika, ixesha lokusebenza konyango lwamehlo ziinyanga ezili-18.
Kubantu abane-myopia, ukuba ukusebenzisa iilensi kudlula "ubomi beshelufu," kunokubangela ukudinwa kwamehlo kwaye kukhawulezise ukuqhubela phambili kwe-myopia ngenxa yokwaluphala kweelensi kunye notshintsho kwimeko yokuchacha kwamehlo. Kubomi bemihla ngemihla, kufuneka sihlale sigcina kwaye sijonge iilensi zethu ukuze sikhusele iiglasi zethu, kwaye kwangaxeshanye, sikhusele amehlo ethu.
Iimpawu zokuphelelwa yiwaranti yeglasi
Ukuba kukho nayiphi na kwezi meko zilandelayo, kuya kufuneka utshintshe iiglasi zakho ngexesha.
1 Ilensi igugile kakhulu
Abanye abantu abakhathali kwaye bathanda ukubeka iiglasi zabo kufutshane, okanye ngempazamo bakrwele iilensi zabo ngelixa bezilolonga. Ukusebenzisa iiglasi ixesha elide ezineelensi ezigugileyo kakhulu kunokukhokelela ekuboneni okufipheleyo kwaye konakalise impilo yokubona.
Iiglasi ezi-2 zikhubazekile kakhulu
Ulutsha ludlamkile kwaye lusebenza, kwaye iiglasi zabo zihlala zigqunywa okanye zinyathelwa ngaphandle kokunika ingqalelo, nto leyo ebangela ukuba iifreyimu ziguquguquke. Ngamanye amaxesha iiglasi ziwela phantsi kwempumlo, kwaye abantwana bayaqhubeka bezinxiba emva kokuzilungisa ngokungakhathali. Abazali kufuneka bajonge iiglasi zabantwana babo yonke imihla ukuze babone ukuba kukho ingxaki yokuguqulwa. Nika ingqalelo ekhethekileyo kwinto yokuba iziko le-optical lelensi kufuneka lihambelane neziko le-pupil leliso. Ukuba alilunganga kakuhle, liya kubangela ukudinwa kokubona, i-strabismus, kunye nokwanda kobukhali bokubona.
3. Indlela ebhalwe ngayo iiglasi ayifani.
Xa uninzi lwabantwana lungakwazi ukubona kakuhle ngeeglasi zabo, abayi kubaxelela abazali babo ngoko nangoko. Endaweni yoko, baya kuzikrwitsha okanye bazinyuse iiglasi zabo ukuze babone, nto leyo eyenza kube nzima kubazali ukuba baqaphele ngoko nangoko. Xa umntwana ejongene nokwanda kwe-myopia ngesiquphe kunye nokungakwazi ukuziqhelanisa kakuhle, kudla ngokufunyaniswa ukuba sele kudlule ixesha ukulungisa ingxaki kwaye kunokunyusa kuphela ummiselo weeglasi.
Abantwana abanxiba iiglasi kufuneka baye kwiziko okanye esibhedlele esiqhelekileyo sokufaka iiglasi ukuze bahlolwe umbono wabo rhoqo (kwiinyanga ezintathu ukuya kwiinyanga ezintandathu). Kufuneka uhlakulele umkhwa omhle wokujonga umbono wakho. Nangona abanye abantwana banokubona i-1.0 ngamehlo omabini, kunokwenzeka ukuba elinye iliso linokufikelela kwi-1.0 kodwa elinye iliso alikwazi. Kunzima ukulibona ngaphandle kokuhlolwa ngononophelo.
Wakuba unxibe iiglasi, ingakumbi ebantwaneni, kufuneka uqaphele indlela ezisetyenziswa ngayo ezi glasi. Musa ukulinda de zibe zonakele kangangokuba zingasakwazi ukusetyenziswa ngaphambi kokuba uzitshintshele ezintsha. Impilo yombono womntwana wakho yeyona nto ibalulekileyo.
Indlela Yokunyamekela Iiglasi
1. Musa ukubeka iiglasi ujonge phantsi.
Beka iiglasi ujonge icala lesipili phantsi. Ukuba ngempazamo uhambisa iiglasi kwifreyimu, iilensi zisenokukrweleka. Ukubeka iiglasi iilensi zijonge ezantsi kulula kakhulu ukuzikrweleka iilensi, nto leyo engafanelekanga.
2. Musa ukubeka iiglasi zakho kumaqondo obushushu aphezulu
Iilensi zanamhlanje zonke ziilensi ze-resin ezigqunywe nge-coated. Iilensi ezigqunywe nge-coated zinokuthintela ngempumelelo imisebe ye-ultraviolet kwaye zonyuse ukuhanjiswa kokukhanya. Umaleko wefilimu welensi ugqunywe phezu komphezulu welensi. Ngenxa yokuba i-coefficient yokwandiswa komaleko wefilimu kunye nezinto ezisisiseko zahlukile, umaleko wefilimu kulula kakhulu ukuwuqhekeza ngenxa yempembelelo yobushushu obuphezulu, okuphazamisa ukukhanya okungena kwi-eyeball, okubangela ukukhanya okukhulu.
Iingcebiso: Iiglasi akufuneki zishiywe emotweni ehlotyeni, kwaye azinakuthathwa xa kuhlanjwa okanye kuselwa kwi-sauna. Kufuneka uphephe ukuba kufutshane kakhulu nelangatye elivulekileyo xa upheka okanye usela inyama. Ubushushu obuphezulu buya kubangela ukuba yonke ifilimu ephezu kwelensi iqhekeke ize ikrazuke.
3. Zama ukungazisuli iilensi ngelaphu leglasi
Xa unxiba iiglasi imihla ngemihla, umphezulu welensi udla ngokufunxa uthuli oluninzi (olungabonakaliyo emehlweni). Ukuba usula ilensi ngqo ngelaphu lelensi ngeli xesha, kufana nokusebenzisa iphepha lokusila ukucola ilensi, kwaye abanye abantu baqhele ukusebenzisa ilaphu lelensi ngezangqa. Ukusula iilensi, konke oku akulunganga.
Ukuba awunazo iimeko zokucoca iiglasi zakho okwethutyana, kufuneka uzisule iilensi ngelaphu lelensi. Kucetyiswa ukuba uzisule iilensi ngobunono kwicala elinye kwaye ungazisuli iilensi ngasemva nangaphambili okanye ngezangqa. Umbane oqinileyo uya kubangela ukuba kungene uthuli oluninzi kumphezulu welensi, ngoko ke ukusula okomileyo ngelaphu lelensi kufuneka kuthintelwe kangangoko kunokwenzeka.
4. Akukho kudibana neekhemikhali
Musa ukusebenzisa ulwelo lokucoca lwe-Amway, ishampu, isepha, umgubo wokuhlamba impahla, okanye isicoci sokungcola esingaphezulu ukuze ucoce iiglasi (iilensi), kuba oku kunokubangela ukuba ifilimu yelensi ixobuke kwaye ixobuke.
Ungazicoca iiglasi zakho wedwa yonke imihla xa usiya ekhaya. Sebenzisa amanzi abandayo kunye nesepha yezitya engathathi cala. Faka isepha yezitya kumacala omabini elensi, uze uyifake ngokulinganayo kwizangqa ngeminwe yakho, uze uhlambe ngamanzi epompo ude kungabikho mvakalelo yokutyeba.
Emva kokucoca, kuya kubakho amathontsi amancinci amanzi kumphezulu welensi. Sebenzisa itawuli yephepha eyomileyo ukufunxa amathontsi amanzi (qiniseka ukuba awuyikhuhli ilensi).
Ukuququmbela
Iiglasi zizinto ezichanekileyo kakhulu kwaye zibola lula, kwaye ukunxiba iiglasi ukulungisa i-myopia lukhetho oluqhelekileyo. Ukukhusela iiglasi kuthetha ukukhusela amehlo ethu. Sinike isikhokelo sobuchwephesha malunga nokugcinwa nokunakekelwa kweeglasi, kodwa okubaluleke ngakumbi, sifuna ukuxelela wonke umntu ukuba iiglasi azizozinto zodidi okanye izinto ezihlala ixesha elide; zizinto ezisetyenziswayo ebomini bethu. Ukuba ufunda oku kwaye ufumanisa ukuba iiglasi zakho azisekho phantsi kwewaranti, nceda ukhumbule ukuzitshintsha ngexesha elifanelekileyo.
