Kubahlobo be-myopic, lonke ixesha usiya kwivenkile yeeglasi ukukhetha isakhelo seglasi yingxaki ebuhlungu kakhulu, kunzima ukukhetha iperi yeeglasi ezifanelekileyo zabo, ukuba namhlanje zifundise indlela yokukhetha iperi yeglasi ezifanelekileyo zabo. isakhelo esakhe.
Inyathelo 1: Khetha ubungakanani besakhelo
1, jonga iqondo: i-myopia lens yi-concave lens, ecaleni kombindi otyebileyo obhityileyo, iqondo eliphezulu, iqondo eliphezulu lelensi, ngoko ke isidanga se-myopia siphezulu abantu abacebisi ukuba bakhethe isakhelo esikhulu, esingesihle. , kodwa kunye nobunzima, kucetyiswa ukuba ukhethe isakhelo esincinci.
I-2, jonga ubuso: ukuthetha ngokubanzi, abantu abanobuso obubanzi akufanele basebenzise iifreyimu ezincinci kunye nezincinci, ubuso obude obude akufanele busebenzise iifreyimu ezibanzi, ukuba unobuso obuqhelekileyo be-oval, ngoko unokukhetha naluphi na uhlobo lweglasi.
Inyathelo lesi-2: Khetha umbala wesakhelo
I-1, umbala wesikhumba omhlophe: khetha ifreyimu yombala okhanyayo, njengepinki ethambileyo, igolide kunye nesilivere;
2, Ulusu olumnyama: Khetha iifreyimu ezimnyama, ezinjebomvu, emnyama okanye iqokobhe lofudo.
I-3, Umbala wolusu ophuzi: kunqanda iifreyimu ezityheli kwaye usebenzise imibala ekhanyayo enje ngepinki, ikofu ebomvu, isilivere kunye nomhlophe;
I-4, umbala obomvu: unqande isakhelo esibomvu, unokukhetha grey, ukukhanya okuluhlaza, isakhelo eluhlaza okwesibhakabhaka, njl.
Inyathelo lesi-3: Khetha uhlobo lwesakhelo
I-1, isakhelo esipheleleyo: kukho isibuko esipheleleyo sokuvala i-lens.Ifanelekile ukuba iimbaleki kunye nabantwana banxibe.Ngenxa yokuba indawo ejikeleze i-lens ikhuselwe ngokupheleleyo yi-lens ring, ifanelekile kwi-lens kunye neeparitha ezahlukeneyo zokuhlaziya.
2, isakhelo sesakhelo sesiqingatha: indawo ephezulu yesipili yenziwe ngentsimbi okanye izinto zeplastiki, kwaye ifakwe ngaphakathi, ucingo lwenayiloni olufakwe ngaphakathi, indawo engezantsi yesipili senziwe ngocingo oluncinci kakhulu lwenayiloni (umzobo wocingo). inxalenye esezantsi yeringi yesipili.Ngenxa yokuba indawo engezantsi ye-lens ayivalwanga sisangqa se-lens, kwaye umda obunzima we-lens uya kuchaphazela ukubonakala, ngoko idigri iphezulu kakhulu ukukhetha olu hlobo lwesakhelo.
I-3, isakhelo esingenafreyimu: akukho ndandatho yesibuko, kuphela ibhulorho yempumlo yentsimbi kunye nonyawo lwentsimbi yesibuko, i-lens kunye nebhuloho yempumlo kunye nonyawo lwesibuko zixhunywe ngokuthe ngqo ngezikrufu, ngokuqhelekileyo ukubhoboza imingxuma kwi-lens.Akukho isakhelo sikhaphukhaphu kwaye sinesithunzi kunesakhelo esiqhelekileyo, kodwa amandla ngokubanzi ambi kancinci kunesakhelo esipheleleyo.Akukhuthazwa ukufanisa olu hlobo lwesakhelo kubantwana.Amalungu ahlukeneyo esakhelo kulula ukukhulula, ubude be-screw bukhawulelwe, kwaye idigri iphezulu kakhulu.
I-4, Isakhelo esidityanisiweyo: kukho amaqela amabini eelensi kwisakhelo sangaphambili sesakhelo sokudibanisa, enye enokuthi iguqulwe, ngokuqhelekileyo ukusetyenziswa kwangaphakathi nangaphandle.Ezona ziqhelekileyo zizikliphu zeglasi zelanga, okanye iikliphu zeglasi ze-3D.Icala elisezantsi lelokuba kunzima ukufumana iikliphu ezilingana nezakhelo, ngaphandle kokuba uthenge iseti epheleleyo.
I-5, isakhelo sokugoba: isakhelo sinokusongwa ngokubanzi kwibhuloho yempumlo kunye nomlenze wesibuko ukunciphisa indawo ehlala isakhelo xa igcinwe okanye ithwalwa;Olu hlobo lwesakhelo lusetyenziswa ngokubanzi kwiiglasi zokufunda.Kulula ukugaya i-lens, kulula ukukhulula uxhumano.
Inyathelo lesi-4: khetha izinto zesakhelo
1, isakhelo sesipili seplastiki: ikakhulu sahlulwe ngokwesakhelo sokutofa kunye nesakhelo seplate iindidi ezimbini.Isakhelo sokubumba isitofu silula ngobunzima, kulula ukusetyenzwa, ukubumba okulungileyo, kodwa kulula ukukhubaza, ukungahambi kakuhle kunye namandla acinezelayo;Isakhelo seplate sinombala oqaqambileyo, ukuqina okuhle kunye namandla oxinzelelo, kodwa inkqubo yokuvelisa inzima ngakumbi.
I-2, isakhelo sesipili sesinyithi: iimpawu zayo zezi: zomelele, zikhaphukhaphu, zintle, isitayile senoveli, ezahlukeneyo.Uninzi luyi-alloy, kwaye ezinye zinokuphela ngokuxhomekeke kwinkqubo yokucwenga.Ukongeza, kukho iifreyimu ezicocekileyo ze-titanium, kunye neefreyimu ze-alloy yememori, eziguquguqukayo, ezihlala zihleli kunye ne-corrosion resistant.
I-3, isakhelo sezinto ezixubeneyo: ubukhulu becala zenziwe ngentsimbi kunye nomxube weplastiki.Ukudibanisa izibonelelo zeplastiki kunye nentsimbi, ukufezekisa ubuhle kunye nokukhanya, ininzi iplastiki yesakhelo, umlenze wesipili sesinyithi, ethandwa kakhulu kule minyaka mibini idlulileyo.
I-4, isakhelo sezinto zendalo: i-tortoiseshell eqhelekileyo, iimpondo zeenkuni kunye neempondo zezilwanyana, njl njl. Kuyinto ehlobisa ngaphezu kwezinto eziphathekayo, i-hawksbill ilula ukuphuka, ukhuni lulula ukubola, kunye nefreyimu yomthi enqabileyo kulula ukunxiba ulusu.Ukubulawa kweehawksbill turtles akuvumelekanga ngoku kwaye kunqabile.
Inyathelo lesi-5: Yizame
I-1, iNtuthuzelo: Ifreyimu yeglasi idinga ukuziva ikhululekile emva kokugqoka, ngaphandle kokucinezela iindlebe, impumlo okanye iitempile, kwaye ayiyi kukhululeka kakhulu.
2, umgama wamehlo, njengoko igama lithetha, ngumgama phakathi kwe-lens kunye neso, ngokuqhelekileyo yi-12MM.Ukuba amehlo akude kakhulu, abantu abane-myopia banokungaboni ngokucacileyo, kwaye abantu abane-hyperopia banokuba ne-diopter ephezulu kakhulu.Okuchaseneyo kuyinyaniso xa amehlo esondelelene kakhulu.Kungcono ukhethe isakhelo sesibuko esinempumlo yentsimbi yokubamba, sinokuhlengahlengisa ubude.
I-3, kuluhlu olukhethiweyo, intando yabo yeyona nto ibalulekileyo.
Phezulu KUKUBA UKHETHE amanyathelo amahlanu efreyimu yeglasi, isakhelo seglasi esifanelekileyo sinokunceda ukulawula i-myopia.Izigulane ze-myopia eziqhelekileyo kufuneka zitshintshwe rhoqo emva kweminyaka emibini ngokuqhelekileyo iiglasi ze-myopia: enye yi "uhlaziyo", 2 kukulungelelanisa isidanga.
