Nhasi, kusarudzwa kwema contact lens kwakanyanyisa. Naizvozvo, zvakakosha kuziva kuti ndechipi chezvigadziriso zvekugadzirisa zvakawana rumbidzo kubva kuvarwere vanovashandisa kuvandudza kuona. Heano epamusoro gumi epamusoro ekuonana lenses ekugadzirisa maonero.
Epamusoro gumi akanakisa kuonana lenses emeso zvinoenderana neKP
Vanhu vazhinji vanozviona zvisina kugadzikana kupfeka magirazi, saka vanosarudza macontact lens kuti vagadzirise kuona kwavo. Midziyo iyi yekurapa inogadzirisa zvikanganiso zve refractive izvo zvinoita kuti mifananidzo iri kure kana pedyo iite seyakasviba. Kazhinji, zvinova zvakakosha kuti usarudze malenzi ekuona pedyo (inonzi izwi rekurapa myopia), kuona kure (aka hypermetropia) kana astigmatism.
Malenzi anogona kupfekwa zuva nezuva, anoiswa mangwanani uye manheru, anobviswa asati aenda kunorara, anoraswa, uye maviri matsva anoshandiswa zuva rinotevera. Imwe sarudzo ndeye lenses inofanirwa kupfekwa kweimwe nguva yenguva (kazhinji mwedzi), uyezve inotsiviwa nepeya nyowani.
