Vamwe vakadzi vanotenda kuti magirasi akaipa kune chimiro, echinjai majekiseni. Asi ivo havakwanisi kutora, saka vanhu vazhinji vari kufunga nezvekusarudza kodzero yekuona lenzi. Mushure mezvose, unofanirwa kufungisisa zvakawanda-kubva kune zvinopesana nezvinodiwa zvako pachako. Mukuwedzera, kushanyirwa kune ophthalmologist kunotarisirwa. Dzimwe tsanangudzo pamusoro pechirongwa chekusarudza lens contact, tichakurukura mberi.
Nezvo zvakakosha kutanga?
Kusarudza lenzi inzira yakaoma, saka unofanira kutevera mitemo inotevera ichakuponesa kubva kune mamwe matambudziko ehutano. Chokutanga pane zvose, zvakakosha kutanga nekushanyira kune ophthalmologist. Zvinoda kuti kubvunzurudza kuitike muhofisi yekombiyuta kuongororwa. Zvishandiso zvemazuva ano zvinogona kunyatsonyatsogadzirisa kuti ndeipi lenzi iwe unoda. Kusanganisira, iyo inofanirwa midziyo ichakwanisa kuyera cornea kuti ione hupamhi hwekodhi yakakodzera. Iyi nhamba yakasiyana kubva pa13 kusvika ku15 mm. Uyezve, zvakakosha kudzidza mabhuku matsva nema lenzi evanhu vakasiyana-siyana vanogadzira, uko kwaisava kungotsanangurwa kwakakwana kwechigadzirwa, asiwo murairo wekutarisira kwacho.
Sezvo uchitarisa mumabhuku akawanda, sarudza izvo zvinonyanya kufanana nezvikurudziro zvechiremba. Uyewo teerera kutarira mutengo. Iko yakakwana yakakwana-yehuwandu yehuwandu inowanikwa mumarangire nemutengo uri pamusoro pevhareji, sezvo iine hutano hwakanaka, uye iwe haufaniri kudhinda.
Zvikamu zve lenzi
Iwe usati watanga kudzidza majekisi evanhu vakasiyana-siyana vanogadzira, zvakakosha kuziva kuti ndezvipi zvikamu zvakaparidzirwa mavara lens, uye ndezvipi zviri nani kusarudza, iwe uchabatsira kuziva kuti iwe unoona sei. Chokutanga pane zvose, lenzi dzose dzakakamurwa kuva mapoka matatu:
- toric - kururamisa astigmatism;
- spherical - kururamisa myopia;
- bifocal - kururamisa kure kure.
Inofanira kuonekwa kuti ivo vakaparadzaniswa zvakare:
- soft;
- rakasimba.
Iko kusagadzikana kweiyo lens kunobva pane zvinhu zvavanenge vaita. Soft lenses zvakakamurwa kuva:
- hydrogel;
- silicone-hydrogel.
Yokutanga ndiyo inonyorera, sezvo shell yavo inosanganisira gel chete, uye mukati imomo mvura. Risiyumu lenzi yakagadzirirwa kururamisa high degree ye astigmatism uye inogadzirwa ne thermoplastic uye silicone. Mukati, iwo anewo mvura, asi mari yacho haisi yepamusoro 50%.
Lenses inogona kuva nekusiyana kwakapfeka kupfeka - kubva pazuva rimwe kusvika pamwedzi. Dzimwe nguva inova inogadzirisa chimwe chinhu. Saka, nguva refu-kupfeka lenzi inogona kushandiswa kubva pavhiki kusvika pamwedzi. Asi lenzi dzakadai, marwadzo, hazvina kukodzera munhu wese, saka chenjerera. Kusiyanisa kupfeka lenzi kunogona kupfekwa pasina kubvisa rimwe kana maviri mazuva. Zuva rezuva lenzi, zvakare, rinogona kupfekedzwa kwete kupfuura zuva rimwechete.
Kuva nechido chekusarudza kodzero yakakodzera yekutora lens, zvichave zvakakosha kuziva kuti ivowo vanosiyana nenzira ye hydrophilicity (yehuwandu hwehuwandu hwemvura). Muduku
Nzira yekusarudza mavara lenzii?
Kusarudzwa kwemavara emaronda kunotonyanya kuoma. Chiremba-ophthalmologist anofanirwa kunge achitaura nezvekusarudza kwemavara lenzi . Asi zvisati zvaitika, anofanirwa kuenzana chaiyo chaiyo, hutengo hwehutano uye anosarudza radius yekuputika. Kuziva migumisiro yezviyero izvi nekuteerera kukurudzirwa kwechiremba, iwe uchaziva kusarudza kodzero yekuona lenzi iwe pachako. Tinokukurudzira kuti iwe ureve kutengesa kune zvigadzirwa kubva kune vanozivikanwa zvikuru vanogadzira, sezvo vachipa tsanangudzo yakanyatsorondedzera yezvigadzirwa zvavo. Nokudaro, une mukana muduku wekuita zvikanganiso. Mukuwedzera, mabhizimusi anozivikanwa ari kutarisisa hutano hwezvigadzirwa zvavo, sezvo vanotya kurasikirwa nevatengi uye vakwikwidzana.
