Abantu abaninzi bahlala benikela ingqalelo kuphela kwi-aesthetics xa bekhetha iiglasi zeefreyimu ze-myopia.Enyanisweni, izibonakaliso ze-optical kunye nemilinganiselo yobugcisa bezakhelo zeglasi zibaluleke kakhulu ekuthuthuzelekeni kwabathengi abanxibe iiglasi.Ukukhethwa kweefreyimu zeglasi kufuneka kuthathelwe ingqalelo kumacandelo amathathu: i-frame aesthetics, umsebenzi wesakhelo kunye nokugqoka induduzo.
Iifreyimu zeSpectacle nazo ziza ngokwesayizi yazo.Ngokuqhelekileyo, iiparitha ezifana nobukhulu besakhelo sokubukela ziphawulwe kwitempile, ibhuloho yempumlo okanye kwisibonakaliso.Umzekelo: imilomo engama-54 18-135, oku kuthetha ukuba ububanzi besakhelo yi-54mm, ububanzi bebhulorho yempumlo yi-18mm, kunye nobukhulu betempile yi-135mm.Okokuqala, kufuneka ukwazi ubungakanani besakhelo seglasi esikufanelayo.Unokujonga iiparitha zeeglasi ezithengiweyo, okanye ulinganise iiglasi ngerula ukuze ufumane idatha, okanye uye kwivenkile ye-optical ukuze uzame, kwaye ubhale phantsi ubungakanani obukufanelayo.
Yazi isidanga sakho samehlo
Idigri ibandakanya iqondo lombono elikufutshane/elikude lamehlo omabini, kunye nomgama we-interpupillary.Ukuba kukho i-astigmatism, iqondo le-astigmatism kunye ne-axis ye-astigmatism kufuneka ibonelelwe.I-axis yi-angle ye-astigmatism, kwaye i-astigmatism ayikwazi ukuhlanganiswa ngaphandle kwe-axis ye-astigmatism.Ukuba awusazi isidanga, ungaya kwivenkile yamehlo okanye esibhedlele uyokumeta isidanga.Idigri yesibhedlele nayo iluncedo kakhulu, kwaye unokulinganisa idigri ngokuxhoma inombolo yesebe lamehlo.
Ingxelo yeOptometry
Khumbula ukufaka i-optometry (oko kukuthi, zama ukunxiba i-insert ukuze ubone itshathi yamehlo okanye ujonge kumgama, ungathathi uluhlu lwe-optometry yekhompyutha njengommiselo ongcwele, nokuba unoluhlu lwe-optometry yekhompyutha, kufuneka ufake i-optometry ngesandla. kwaye uyiguqule), okokuqala ukunxiba iindondo kwaye Abo bangafane banxibe iiglasi kufuneka bafake i-refraction, kungenjalo kunokwenzeka ukuba banxibe isiyezi.Ngokumalunga nomgama we-interpupillary, umgama jikelele we-interpupillary yi-60mm-70mm kumadoda kunye ne-58mm-65mm yabasetyhini.Umbindi womfundi kunye nelensi ihambelana neyona nto ifanelekileyo.
Ukukhetha iilensi
Ngokuqhelekileyo, idigri ayiphezulu (0-300), kwaye isalathisi se-refractive se-1.56 sinokukhethwa.Kwiqondo eliphakathi (i-300-500), i-index refractive ye-1.61 inokukhethwa.800 nangaphezulu).Ukuphakama kwesalathiso se-refractive ye-lens, i-thinner edge ye-lens yezinga elifanayo, ixabiso eliphezulu.Ngoku ii-brand ezaziwayo zehlabathi zi-Essilor kunye ne-Zeiss, ii-brand ezaziwayo zasekhaya yi-Mingyue, kwaye kukho iintlobo ezahlukeneyo zasekhaya nezangaphandle.Iilensi zibiza naphi na ukusuka kumakhulu ambalwa ukuya kumawaka ambalwa.Ngexabiso eliphantsi kwi-intanethi!
Ifanelekile ukuma kobuso kunye nokudibanisa umbala
Ngokuqhelekileyo, ubuso obujikelezileyo bufanelekile ukugqoka isakhelo sesikwere, kunye nobuso besikwere kunye nobuso baseTshayina kunye nobuso be-melon bufanelekile ukugqoka isakhelo esijikelezileyo.Ukutshatisa umbala kusekelwe ikakhulu kukhetho lomntu, kwaye abo baqolileyo ngakumbi bangamathoni amnyama.Abantu abancinci kunye nabo banesimo sengqondo esincinci banokuzama iifreyimu zeglasi ze-retro ezithandwayo kutshanje.Iqokobhe loFudo kunye nombala wehlosi ziyatsiba kancinci, kwaye zezolutsha olusulungekileyo.
Ngokuqhelekileyo, ukuba unombala ococekileyo, kufuneka ukhethe isakhelo esinombala okhanyayo, njengepinki ethambileyo, igolide kunye nesilivere, njl.;ukuba unombala omnyama, kufuneka ukhethe isakhelo esinombala omnyama, njengombala obomvu, omnyama okanye we-tortoiseshell, njl.Ukuba umbala wolusu utyheli, kuphephe ifreyimu emthubi, ingakumbi ngemibala ekhanyayo efana nepinki, ikofu ebomvu, isilivere, nemhlophe;ukuba umbala wolusu ubomvu, gwema isakhelo esibomvu, khetha grey, ukukhanya okuluhlaza, isakhelo esiBlue, njl.
