Namhlanje, ulutsha oluninzi luvakalelwa kukuba ukunxiba iiglasi zefreyimu engaphezulu kunokwenza ubuso babo bubonakale buncinci, nto leyo efashisayo kwaye isefashonini. Nangona kunjalo, abanakukwazi ukuba iiglasi zefreyimu ezigqithisileyo zihlala zisinye sezizathu zokuwohloka kombono kunye ne-strabismus. Enyanisweni, akuyena wonke umntu ofanelekileyo ukunxiba iiglasi zefreyimu engaphezulu! Ngokukodwa kubantu abanomgama omxinwa we-interpupillary kunye ne-myopia ephezulu!
ILens kunye neengcebiso zokuLungiselela
1. Indawo ye-optical center yazo zonke iilensi kufuneka ibe kumbindi ngqo welensi.
2. Ubukhulu be-lens blanks ngokubanzi buphakathi kwe-70mm-80mm.
3. Umgama phakathi kwe-interpupillary kuninzi lwabasetyhini abadala uqhelekile uphakathi kwe-55mm-65mm, kwaye malunga ne-60mm yeyona ixhaphakileyo.
4. Kungakhathaliseki ukuba ubungakanani besakhelo, ngexesha lokucubungula, indawo ye-optical center ye-lens kufuneka ikhutshwe ngokufanelekileyo ukuze ihambelane nomgama we-interpupillary kunye nokuphakama komfundi.
Iiparamitha ezimbini ezibalulekileyo kwi-lens fitting zi-diopter kunye nomgama we-interpupillary. Xa ufaka iiglasi zefreyimu enkulu, ngakumbi umgama we-interpupillary parameter kufuneka uqwalaselwe. Umgama phakathi kwamaziko eelensi ezimbini kufuneka uhambelane nomgama we-interpupillary; ngaphandle koko, nokuba ngaba i-prescription ichanekile, ukunxiba iiglasi kunokubangela ukuphazamiseka kwaye kuchaphazele umbono.
Imiba eBangwe kukuNxitywaIsakhelo esinobukhulu obugqithisileyoIiglasi
Isakhelo sisebenza umsebenzi wokuzinzisa, ukuvumela iilensi ukuba zibe kwindawo efanelekileyo yokusebenza ngokufanelekileyo, ngoko ukuzinza kubalulekile. iiglasi zefreyimu ezigqithisileyo, ngenxa yeelensi zazo ezinkulu, zinokuba nefuthe elithile emehlweni, okukhokelela ekungonwabi xa zinxitywa ixesha elide.
Iiglasi zefreyimu ezigqithisileyo zinokuba nzima, kwaye ukuzinxiba ixesha elide kunokucinezela imithambo-luvo kwibhulorho yempumlo kunye nokujikeleza kwamehlo, ukubeka uxinzelelo olugqithisileyo kwimisipha yamehlo kwaye kukhokelela ekudinweni kwamehlo. Ukunxiba ixesha elide kunokubangela ukudumba kwamehlo, intloko ebuhlungu, ububomvu, kunye noxinzelelo lwamehlo. Ukongeza, abantu abanxibe iiglasi ezinkulu zefreyimu banokufumanisa ukuba ukujonga phantsi okanye ukunyakaza kwentloko ngequbuliso kunokubangela ukuba iiglasi zityibilike ngokulula.
Iiglasi zefreyimu ezinobukhulu obugqithisileyo zinokuchaphazela inkangeleko yabantu. Ukunxiba iifreyimu zeglasi ezinzima kakhulu kunokubangela ukugqwetheka kobuso, ngakumbi ukuchaphazela ibunzi, ibhulorho yempumlo, kunye nesilevu ukuya kwinqanaba elithile. Ngethuba lenkqubo yokugqoka iiglasi, ukuba umntu unamehlo amancinci, ifreyimu yeglasi inokucinezela amehlo, ibenze babonakale bencinci; ukuba umntu unamehlo amakhulu, iifreyimu zeglasi ezinzima kakhulu zinokwenza amehlo abonakale makhulu ngakumbi.
Umba we-Interpupillary Distance ngeIsakhelo esinobukhulu obugqithisileyoIiglasi
Iilensi ezigqithisileyo zeeglasi zefreyimu ezinobukhulu obugqithisileyo zingenza kube nzima kwiziko lokubonwayo ukulungelelanisa nomgama wokwenene we-interpupillary. Isakhelo esigqithisiweyo seeglasi sihlala sibangela ukuba iziko le-optical lens libe likhulu kunomgama phakathi kwabafundi, kubangela ukungahambi kakuhle phakathi kweziko le-optical lens kunye nezikhundla zabafundi. Oku kungahambi kakuhle kunokukhokelela kwiimpawu ezinjengokuncipha kombono, i-strabismus, isiyezi, kwaye ixesha elide umntu enxibe ngalo, ayanda amathuba okunyuka kwe-myopia.
Ukongezelela, kubalulekile ukuqaphela ukuba amandla okuhlaziya iindawo ezahlukeneyo zelensi azifani. Ngokuqhelekileyo, amandla ahlaziyayo kumbindi welensi angaphantsi kancinane kunalawo akumda welensi. Abafundi bethu bagxininise kumbindi welensi, ke ngoko ukunxiba iiglasi zefreyimu enkulu kakhulu rhoqo kunokukhokelela ekutyibilikeni kweeglasi ngenxa yobunzima bazo. Oku kunokubangela ukungahambi kakuhle phakathi kokugxilwa komfundi kunye nendawo ye-lens, okubangelwa ukuphazamiseka okubonakalayo kunye nokuhla okuqhubekayo kombono.
Kwenziwa kanjaniChola iRbusukuGabafaziFRame?
1.Ikhaphukhaphu, ilula ngakumbi. Isakhelo esikhaphukhaphu sinokunciphisa uxinzelelo empumlweni, siyenze sikhululeke!
2. Ayikhubazeki lula, ibaluleke kakhulu! Iifreyimu ezithambekele kwi-deformation azichaphazeli kuphela ixesha lokuphila kodwa zichaphazela umphumo wokulungisa umbono.
3. Umgangatho ogqwesileyo, obaluleke ngakumbi. Ukuba isakhelo sinomgangatho ombi, sithande ukuqhawuka kunye nokutshintsha kombala, okuchaphazela ngqo ukuqina kwesakhelo.
4. Ukuhambelana kobuntu, kubaluleke kakhulu. Iimpawu zobuso bomntu wonke ziyahluka, nokuba bubuso obugcweleyo okanye obuncinci, ibhulorho yempumlo ephakamileyo okanye ephantsi, okanye i-asymmetry phakathi kweendlebe ezisekhohlo nasekunene kunye nobuso, okukhokelela ekunxibeni okungafanelekanga. Ngoko ke, kubalulekile ukukhetha isakhelo esihambelana neempawu zakho zobuqu.

1. Kubantu abaneqondo eliphakathi ukuya kwiqondo eliphezulu lemposiso ye-refractive, ukukhetha iifreyimu ezinobukhulu obugqithisileyo akunakuwusombulula umba wemiphetho eshinyeneyo yeelensi, kungakhathaliseki ukuba sisiphi na isalathiso esiphezulu se-refractive seelensi ezikhethiweyo. Nokuba idigri ye-myopia iphantsi, imiphetho yeelensi iya kuba ngqindilili.
2. Xa ukhetha iiglasi zefreyimu ezingaphezulu, kuyacetyiswa ukuba ukhethe izinto ezilula ezifana ne-TR90 / titanium metal / insimbi yeplastiki kunezixhobo zeplate (ezinzima). Imilenze yefreyimu akufuneki ibe mncinci kakhulu, njengoko iifreyimu ezingaphambili zinzima kunye nezikhanyisa ngasemva zinokubangela ukuba iiglasi zityibilike ezantsi rhoqo.
Wonke umntu ufuna ukuba nenkangeleko entle, kodwa nceda ungalibali ukuba impilo yamehlo yeyona nto ibalulekileyo. Ukuba ungayihoyi injongo yokulungisa umbono ngenxa yento ebizwa ngokuba "ubuhle," kwaye ekugqibeleni ubangele ezinye izifo zamehlo, kuya kuba yingozi kakhulu.
Xa ukhetha iifreyimu zeglasi, ukongeza ekuthatheni ingqalelo imilo yobuso bakho, i-hairstyle, ithoni yesikhumba, njl.njl., kubalulekile ukuba uqaphele imeko yamehlo akho kwaye ukhethe iifreyimu ezikufanelayo. Kuphephe ukukhetha ngokumfamekileyo iifreyimu ezinobukhulu obukhulu, njengoko oku kunokukhokelela kwiingxaki ezibonakalayo ezingeyomfuneko.
