Iyo base curvature yeakawanda anotengeswa anowanikwa contact lenses anotangira pa8-9 mm. Zvichienderana neiyo yakakosha curvature yelens uye chimiro checornea, kukwana kweiyo contact lens inogona kuve yakajairika, yakati sandara kana kukwira.
Iine flat fit, iyo lens ichanyanya kufambisa uye inofamba zviri nyore kana ichibwaira, ichikonzera kusagadzikana. Iine mukwidza (kana kusimba) kukwana, iyo lenzi haifambe, iyo isingakonzerese kusagadzikana, asi inogona kukonzera matambudziko gare gare.
Mushure mekuona zvose zvinodiwa parameters, chiremba anopa mishonga yekuona lens. Nezvo, iwe unoenda kune optics salon, uchitora lenzi dzinokukodzera iwe.

- chiremba anotaurira zvakadzama uye anoratidza mukuita maitiro ekuisa zvakanaka uye obva abvisa lenzi, anotaura nezvemitemo yekupfeka uye kutarisira;
- kana itching, kusagadzikana kana kubvarura, kuoma kwakanyanya kunonzwika, vamwe vanosarudzwa maererano nechinhu kana ma parameter e lens.
Mibvunzo nemhinduro dzakakurumbira
Takakurukura na ophthalmologist Ksenia Kazakova mibvunzo pamusoro pekusarudzwa kwema lens, nguva yekupfeka kwavo, mitemo yekupfeka uye kubvisa, kutarisira lenzi.
Ndeupi rudzi rwe lens yekusarudza?
Hydrogel lenses -Ichi chizvarwa chekare chezvigadzirwa, ivo vane zvese zvavo pluses uye mamwe minuses. Iyo hydrogel ine chikamu inoumbwa nemvura, saka lenzi dzinochinjika uye dzakapfava. Asi ivo havakwanise kupfuudza okisijeni mukati mavo, iyo cornea inoigamuchira yakanyungudika kubva mumvura iri mulens. Nekupfeka kwenguva refu kwema-lenses, cornea inooma uye kusagadzikana kunoitika, saka nguva yekuramba uchipfeka inogumira - anenge maawa gumi nemaviri. Mune lenses dzakadaro, hapana nyaya inobvumirwa kurara.
Silicone hydrogel lenses nekuda kwezvakagadzirwa nesilicone mukuumbwa kwavo, okisijeni inopfuudzwa kune cornea, inogona kupfekwa zvakanaka mukati mezuva, kurara kunobvumirwa mavari, uye vamwe vanobvumirwa kupfeka kwenguva refu (mazuva akati wandei zvichienderera).
Malenzi anofanira kuchinjwa kakawanda sei?
Mazuva ese lenzi iyo yakanyanya kugadzikana uye yakachengeteka, asi mutengo wavo wakakwira kupfuura mamwe ese. Mangwanani, unovhura ma lens matsva, uapfeke uye upfeke zuva rose, usati waenda kunorara, ubvise uye uirase kure. Ndivo vari nyore kutarisira. Hazvidi kucheneswa uye kurapwa nemhinduro dzakakosha. Aya lenzi akanyanya kunaka kune vanhu vane predisposition kune allergies uye kazhinji kuzvimba kwemaziso zvirwere.
Yakarongwa kutsiva lenzi -Iyi ndiyo imwe yezvakajairika sarudzo. Vanopfekwa kwenguva yemavhiki maviri kusvika kumwedzi mitatu.
