Vanhu vazhinji vane magirazi akashatisa kwemakore
Panogona kunge paine kusava nechokwadi kwakadaro se:
Kupfeka magirazi kwenguva yakareba, haina kujeka kuwirirana kwesimbe
Myopia ne hypereropia? Ndeipi imwe-inotarisa uye yakawanda-kutarisa?
Benzi haribve mutsauko
Kusarudza Lenses anotonyanya kuvhiringidza:
Rudzii rwemarara rwakakodzera iwe?
Kune marudzi ese emabasa? Ndezvipi zvinhu zvandinoda?
Kune marudzi ese emafensi;
Kana iyo lens ikakamurwa kubva pane iyo inotarisisa, inogona kukamurwa kuita single fens lens (monopotto), kaviri fens, mriri miviri fens.
Inofambira mberi midzi yemiltificeal lenses, anozivikanwawo selensive inofambira mberi, ine mapoinzi mazhinji emahara pane lens.
Nhasi ticha taura nezve multificeal inofambira mberi lenses
Chii chiri kufambira mberi multificeal lens?
Inofambira mberi magirazi emarudzi mazhinji, ayo ane akawanda mafirita emakiromita pane imwe lens panguva imwe chete, zvishoma nezvishoma shanduko kubva kunzvimbo iri kure kumusoro kweiyo nzvimbo yepedyo pazasi.
Kuve nemadhigirii akawanda pamahombekombe akagoverwa mumatunhu matatu: kure, pakati uye pedyo:
1, iyo yepamusoro maonero nzvimbo iri kure
Inoshandiswa kwenguva refu yekuona, sekutamba, kufamba, nezvimwe
2, pakati penzvimbo yepakati
For yepakati kure chiratidzo, sekutarisa kombiyuta, uchiona TV, nezvimwe
3. Lower Tarisa padyo nenzvimbo
Inoshandiswa pakuona kwepedyo, sekuverenga mabhuku, mapepanhau, nezvimwe
Naizvozvo, chete kupfeka magirazi maviri, anogona kugutsa zvinodiwa kure, maona, ona pedyo nekova chiratidzo.
Zvakajairika physiological phenomena:
Presbypia, iyo zvishoma nezvishoma inoratidzika nekuwedzera kwezera, kunonyanya kuratidzwa sekukasira uye kutadza kuona zvinhu zviri padyo. Iyi mamiriro ichaderedza kushanda kwebasa uye kukanganisa hupenyu hwehupenyu.
Kufambira mberi multificeal Lenses mhinduro yakanaka yedambudziko iri
Nebasa rakanaka
Zvakawanda zvaida uye zvakatsvaga mushure mekunyora
