Abantu abaningi bavame ukunaka kuphela ubuhle lapho bekhetha izibuko ozimele for myopia.Eqinisweni, izinkomba zezobuchwepheshe ze-optical and measurement of glasses frames zibaluleke kakhulu ekududuzeni kwabathengi abagqoke izibuko.Ukukhethwa kwamafreyimu we-eyeglass kufanele kucatshangelwe kusuka ezingxenyeni ezintathu: uhlaka lwe-aesthetics, umsebenzi wefreyimu nokugqoka induduzo.
Amafreyimu e-Spectacle nawo afika ngosayizi wawo.Ngokuvamile, imingcele efana nobukhulu befreyimu yombukwane imakwe ethempelini, ibhuloho lekhala noma uphawu.Isibonelo: imilomo engu-54 18-135, okusho ukuthi ububanzi befreyimu bungu-54mm, ububanzi bebhuloho lekhala bungu-18mm, nosayizi wethempeli ngu-135mm.Okokuqala, udinga ukwazi ubukhulu befreyimu yezibuko evumelana nawe.Ungahlola amapharamitha ezingilazi ezithengiwe, noma ulinganise izibuko ngerula ukuze uthole idatha, noma uye esitolo sezinto ezibonakalayo ukuze uzizame, bese ubhala phansi usayizi ofanele wena.
Yazi idigri yamehlo akho
Idigri ifaka idigri yokubona eduze/kude kwawo womabili amehlo, kanye nebanga le-interpupillary.Uma kukhona i-astigmatism, izinga le-astigmatism kanye ne-axis ye-astigmatism kudingeka ihlinzekwe.I-axis i-angle ye-astigmatism, futhi i-astigmatism ayikwazi ukuqoqwa ngaphandle kwe-axis ye-astigmatism.Uma ungazazi iziqu, ungaya esitolo samehlo noma esibhedlela ukuze ulinganise iziqu.Iziqu zesibhedlela nazo zilula kakhulu, futhi ungakwazi ukukala idigri ngokulenga inombolo yomnyango wamehlo.
Isitatimende se-Optometry
Khumbula ukufaka i-optometry (okungukuthi, zama ukugqoka okufakiwe ukuze ubone ishadi lamehlo noma ubheke kude, ungathathi uhlu lwe-optometry yekhompyutha njengomthetho ongcwele, noma ngabe unohlu lwe-optometry yekhompyutha, kufanele ufake i-optometry ngesandla. futhi uyiguqule), okokuqala egqoke izibuko futhi Labo abangavamile ukugqoka izibuko kufanele bafake i-refraction, ngaphandle kwalokho kungenzeka kakhulu ukugqoka isiyezi.Mayelana nebanga le-interpupillary, ibanga elijwayelekile le-interpupillary lingu-60mm-70mm kwabesilisa no-58mm-65mm kwabesifazane.Isikhungo somfundi kanye nelensi sihambisana nokulingana okunethezekile kakhulu.
Ukukhetha lens
Ngokuvamile, i-degree ayiphezulu (0-300), futhi inkomba ye-refractive ye-1.56 ingakhethwa.Ngokwezinga eliphakathi (300-500), inkomba ye-refractive ye-1.61 ingakhethwa.800 nangaphezulu).Uma iphezulu inkomba ye-refractive yelensi, iba mncane unqenqema lwelensi yezinga elifanayo, intengo iyanda.Manje imikhiqizo eyaziwa emhlabeni wonke yi-Essilor kanye ne-Zeiss, imikhiqizo yasekhaya eyaziwa kakhulu yi-Mingyue, futhi kunezinhlobo ezihlukahlukene zasekhaya nezangaphandle.Amalensi abiza noma yikuphi ukusuka kumakhulu ambalwa ukuya ezinkulungwaneni ezimbalwa.Kushibhile ku-inthanethi!
Ifanele ukuma kobuso nokumatanisa kombala
Ngokuvamile, ubuso obuyindilinga bufanele ukugqoka ifreyimu yesikwele, futhi ubuso besikwele obunobuso bezinhlamvu zesiShayina kanye nobuso bekhabe bufanele ukugqoka ifreyimu eyindilinga.Ukumataniswa kombala kusekelwe ngokuyinhloko ekuthandeni komuntu siqu, futhi abavuthiwe kakhulu ikakhulukazi amathoni amnyama.Abantu abasha kanye nalabo abanomqondo omncane bangazama amafreyimu ezibuko ze-retro athandwa kakhulu muva nje.Umbala wegobolondo lofudu kanye nengwe uyagxumagxuma kancane, futhi ezabantu abasha abamsulwa.
Ngokuvamile, uma unebala elimhlophe, kufanele ukhethe uhlaka olunombala okhanyayo, njenge-pink ethambile, igolide nesiliva, njll.;uma unombala omnyama, kufanele ukhethe ifreyimu enombala omnyama, njengombala obomvu, omnyama noma we-tortoiseshell, njll.Uma umbala wesikhumba uphuzi, gwema uhlaka oluphuzi, ikakhulukazi ngemibala ekhanyayo enjengobomvana, ikhofi elibomvu, elisiliva, nelimhlophe;uma umbala wesikhumba ubomvu, gwema ifreyimu ebomvu, khetha okumpunga, okuluhlaza okukhanyayo, Uhlaka Oluluhlaza okwesibhakabhaka, njll.
