Vanhu vazhinji vakapfeka magirazi kwemakore
Panogona kuva nekusava nechokwadi kwakadai se:
Kupfeka magirazi kwenguva yakareba, hazvinyatso kujeka kurongwa kwema lens
Myopia uye hyperopia?Chii chinonzi single-focus uye multi-focus?
Benzi harigone kutaura mutsauko
Kusarudza lenzi kunotonyanya kuvhiringa:
Ndeupi rudzi rwe lens rwakakukodzera iwe?
Kune marudzi ese emabasa?Ndezvipi zvinhu zvandinoda?
Kune marudzi ese emalenzi;
Kana iyo lenzi yakakamurwa kubva pane yakatarisa, inogona kupatsanurwa kuita imwe focal lens (monophoto), kaviri focal lens, akawanda focal lens.
Progressive multifocal lenses, anozivikanwawo seanofambira mberi lenzi, ane akawanda anotarisisa mapoinzi palenzi.
Nhasi tichataura nezve multifocal progressive lenses
Chii chinonzi progressive multifocal lens?
Progressive multifocal magirazi, ane akawanda anotarisisa mapoinzi pane imwe lenzi panguva imwe chete, zvishoma nezvishoma shanduko kubva kunzvimbo iri kure kumusoro kwelens kuenda kunharaunda iri pazasi.
Kuve nemadhigirii akawanda pane imwechete lens yakakamurwa kuita matunhu matatu: kure, pakati uye pedyo:
1, iyo yekumusoro yekuona nzvimbo iri kure
Inoshandiswa kuona kure kure, sekutamba, kufamba, nezvimwe
2, pakati pedunhu repakati
Zvekuona zviri pakati nepakati, sekuona komputa, kuona TV, nezvimwe
3. Kuona kwepasi pedyo nenzvimbo
Inoshandiswa pakuona zvakanyanya, sekuverenga mabhuku, mapepanhau, nezvimwe
Nokudaro, kungopfeka magirazi chete, kunogona kugutsa kudiwa kure, ona, ona pedyo nechiratidzo.
Normal physiological phenomena:
Presbyopia, iyo inooneka zvishoma nezvishoma nekuwedzera kwezera, inonyanya kuratidzwa seyakasviba uye isingakwanisi kuona zvinhu zviri pedyo.Iyi mamiriro achaderedza kushanda kwekushanda uye kukanganisa mararamiro ehupenyu.
Progressive multifocal lenzi mhinduro yakanaka kune iri dambudziko
Nebasa rakanakisa
Zvakawanda zvinodiwa uye zvakatsvakwa kubva pakunyorwa
