Kuvhiringidza kwemaonero inoshanda kunoitika zvikonzero zvakasiyana-siyana. Inogona kuva:
- ophthalmic diseases;
- hereditary predisposition;
- kupera kwemaziso kwenguva yakareba, nezvimwe.
Imwe yezvisarudzo zvisiri izvo zvepamusoro yekugadzirisa kwekuona zvakapfeka magirazi nemakomba (perforating glasses).
Ko magirazi ane masango anoshanda sei?
Magirazi mugomba rekuvandudza maonero mapepa epurasitiki ane mashumo akawanda maduku, akarongedzerwa mukugadzikana, akaumbwa nepurasitiki, zvisingatoweri masimbi, mafaira. Nheyo yekuitwa kwegandazi dema nemabako inobva pamigumisiro ye pinhole kamera kana stenstop. Pamusana pehukuru hwemafuro, kupararira kwechiedza pane retina kwakaderedzwa, uye mufananidzo unoguma unowedzera uye unopinza.
Ko magirasi nemakomba anobatsira kudzorera chiratidzo?
Mubvunzo wekubudirira kwechiito chegirazi-simulator inomutsa kukurukurirana kukuru. Dzimwe nyanzvi-ophthalmologists dzinofunga kuti chigadzirwa ichi hachina chekurapa, uye kutenga magirazi anoputika inoparadza mari.
Zvimwe oculists vanodavira kuti kushandiswa kwegirazi magirazi nemakomba kunobatsira nenzira yakakodzera yekudzivisa kukanganiswa kubva kumeso emeso ega, uyewo kunobatsira pakugadzira rimwe mutoro pamatambudziko asina simba. Chirwere chenguva refu uye chenguva dzose nerubatsiro rwegorozi dzakadaro chinangwa chekuwedzera maonero ehutano ne 0.5-1.0 diopters. Hazvisi nyore kuwana zvigaro zvikuru mukudzorera chiratidzo.
Zviratidzo zvekushandiswa kwekugadzirisa magirasi
Magirazi ekugadziriswa kwemufananidzo mukati megomba anokurudzirwa kuti ashandiswe mune zviitiko zvinotevera:
- kureba;
- kupona-kuona;
- astigmatism;
- anisometropia (kusiyana kwakasiyana-siyana mumeso);
- presbyopia (lens kuchinja);
- asthenopia (maziso emeso).
Zvinorambidzwa kushandisa magirazi paforforating apo
Nzira yekushandisa magirazi nemakomba?
Kuti uwane hutano hunobatsira, zvinokosha kushandisa magirasi-simulator kwehafu yeawa imwe pazuva. Mune basa rezvemhizha rinosanganisira chinhu chinokosha chekuona, zvinokurudzirwa kupfeka magirazi kwemaminitsi 10 mushure meawa ese maawa 1-1.5 ekushanda. Zvakakosha kusaisa pfungwa pane imwe nyaya panguva imwe chete, asi kutarisa zvinhu zvepedyo uye zvakanyanya kure, zvichiita kuti maziso ako aende nguva dzose. Nguva yenguva yekurapa inenge gore rimwechete.
