Nezvehupenyu hwakakodzera hwebasa remagirazi, vanhu vazhinji havana mhinduro chaiyo.Saka kangani iwe unoda magirazi matsva kuti udzivise rudo pameso?
1. Magirazi ane hupenyu hwebasa
Vanhu vazhinji vanotenda kuti dhigirii ye myopia yakagadziriswa, uye magirazi haasi zvokudya nemishonga, izvo zvisingafaniri kuva nehupenyu hwebasa.Muchokwadi, kana tichienzanisa nezvimwe zvinhu, magirazi rudzi rwechinhu chinodyiwa.
Chokutanga pane zvose, magirazi anoshandiswa zuva nezuva, uye furemu iri nyore kusunungura kana kukanganisa mushure menguva refu.Chechipiri, iyo lens inowanzoita yero, kukwenya, kutsemuka uye kumwe kubvongodzwa.Mukuwedzera, magirazi ekare haakwanisi kugadzirisa maonero azvino kana dhigirii re myopia richichinja.
Matambudziko aya anogona kukonzera mhedzisiro yakawanda: 1) deformation yechimiro inokanganisa kunyaradza kwekupfeka magirazi;2) kubvongodzwa kwema lens kunokonzera nyore kuona zvinhu zvisina kujeka uye kurasikirwa kwekuona;3) Chiratidzo hachigone kururamiswa zvakanaka, kunyanya mukukura kwemuviri kwevechiri kuyaruka, kunowedzera kukura kwemyopia.
2. Kangani kuchinja magirazi eziso?
Unofanira kuchinja magirazi kakawanda sei?Kazhinji kutaura, kana paine kudzika kweziso dhigirii, lens abrasion, magirazi deformation, nezvimwewo, zvinotofanira kutsiva magirazi kamwechete.
Vechidiki nevana:Inokurudzirwa kutsiva lenzi kamwe chete pamwedzi mitanhatu kusvika pagore.
Vechidiki nevana vari munguva yekukura nekukura, uye mutoro unorema wezuva nezuva wezvidzidzo uye kudiwa kukuru kwekushandiswa kwemaziso nyore kunotungamira kune dhigirii remyopia yakadzika.Nokudaro, vana vari pasi pemakore gumi nemasere vanofanira kuongororwa maziso mushure memwedzi mitanhatu yega yega.Kana iyo dhigirii ichichinja zvakanyanya, kana magirazi akadzikira zvakanyanya, zvinotofanira kushandura lenzi nenguva.
Vakuru:Inokurudzirwa kutsiva lenzi kamwe pagore nehafu.
Kazhinji, chiyero che myopia muvanhu vakuru chakanyatsogadzikana, asi hazvirevi kuti hachizoshanduki.Zvinokurudzirwa kuti vanhu vakuru vaite optometry kanokwana kamwe pagore, kuitira kuti vanzwisise hutano hweziso uye chiono pamwe neabrasion uye kubvaruka kwemagirazi, pamwe chete nemamiriro ezuva nezuva emeso uye maitiro, vanyatso ongorora zvakakwana kana votsiva.
Mugari mukuru:Magirazi ekuverenga anofanirawo kutsiviwa sezvinodiwa.
Iko hakuna yakatarwa nguva yakatarwa yekutsiviwa kwemagirazi ekuverenga.Apo vanhu vakuru vanonzwa maziso avo kurwadza uye kusagadzikana panguva yekuverenga, vanofanira kuenda kuchipatara kuti vaonezve kana magirazi akakodzera.
3. Nzira yekuchengetedza sei magirazi?
√Tonga woisa pamagirazi nemaoko maviri, woisa lens convex kumusoro patafura;
√Kazhinji tarisa kuti screws pagirazi regirazi rakasununguka here kana kuti furemu yakaremara, uye gadzirisa dambudziko nenguva;
√Usapukuta lenzi nemucheka wakaoma wekuchenesa, zvinokurudzirwa kushandisa sarudzo yekuchenesa kuchenesa lenses;
√Usaisa lenzi muzuva rakananga kana tembiricha yakakwira.
