Nezera, simba rekuona richiderera kunyange kune avo vanhu avo muupenyu hwose vane zviratidzo zvakakwana. Sezvo mutemo, mumadzimai nevarume mushure memakore makumi mana, presbyopia inokura, kana kuti yakareba kwenguva refu. Nenzira yakawanda, dambudziko iri harisi kunyanya kuwedzera kunaka kwehupenyu, zvisinei, zvinenge zvichizviratidza pachakaedza kuverenga bhuku kana pepanhau.
Mumamiriro ezvinhu akadaro, vanachiremba vanokurudzira kutenga magirazi anokosha pakuverenga. Nhasi mu saloni imwe neimwe ye optics pane zvakasiyana-siyana zvakadai zvakawanikwa, pakati pazvo zvakaoma kuwana mhando yakakodzera.
Mitauro yegorozi yekuverenga
Pakati pezvikwata zvakasiyana-siyana zvezvipfeko zvakafanana zvinokonzera zvinotevera:
- magirazi ne single-focus lenses . Vanopa maonero akanaka ekuonekwa kwepamusoro pamasendimita 30-40 kubva maziso uye anongotarisirwa chete kuverenga. Kana iwe wakatotanga kupfeka magirazi kana lenzi yekugadzirisa zvinetso zvehupombwe, izvi zvigaro zvinofanira kuva kwauri wechipiri, uchiita basa rayo pakarepo. Mumamiriro ezvinhu akadaro, mumwe anowanzozvitenga kupeta magirazi e-focal for reading in case in order to get them out for some time and immediately remove after reading the books necessary;
- zvishoma zvakanyanya magirasi-zvigaro zvekuverenga zvine lenzi, zvakakamurwa kuva 2 optical zones. Chikamu chepamusoro chegorozi yakadaro yakagadzirirwa kunyatsofungisisa zvinhu zviri mumwero wakakura, uye iyo yepamusoro yekuvandudza maonero pedyo, apo kutungamirirwa kwemaziso kunomhanya pasi. Kunyanya, iyi ndiyo mamiriro ezvinhu anoonekwa paanoverenga bhuku kana pepanhau. Pamusana pemufananidzo wakaoma uye lens, inogoverwa muzvikamu nechinhu chinokosha, magirazi akadaro anogona kushandiswa mumamiriro ezvinhu akasiyana, saka vanogona kutora nzvimbo dzakasiyana-siyana kamwe chete;
- iyo yakanakisisa yekuverenga magirasi kusvika pano ndeyezvinhu zvinowedzera mberi lenzi , simba rekushandisa iro rinowedzera kana richiderera zvichienderana nekuti kure kure nemeso chinhu chinenge chichifungidzirwa. Izvi magirazi zvakagadzirwa mumwe nomumwe kune munhu mumwe nomumwe uye zvinodhura, saka havasi vose vanogona kutenga chinhu ichi.

Zvisizvo zvakakodzera kukoshesa magirazi kuitira kuverenga kwenhema . Kunyange zvazvo vanachiremba vasingakurudzire kuverenga mune chimiro chinonyangadza, vanhu vazhinji havagone kusiya tsika iyi. Mumamiriro ezvinhu aya, unogona kushandisa magirasi anokosha achabvisa kusangana kwakanyanya kubva pameso uye kumucheto wemumhino. Panguva imwe chete, vanhu vose vanogona kushandisa zvinhu zvakadaro, pasinei nezera uye kuvapo kwematambudziko e ophthalmologic.
