Zvakangofanana nematayi, bhurasho remazino uye mabhatiri, lenzi anewo zuva rekupera.Saka, ma lenzi anogona kugara kwenguva yakareba sei?Chaizvoizvo, lenzi dzinogona kushandiswa zvine musoro kwemwedzi gumi nemiviri kusvika kumwedzi gumi nemisere.

1. Kutsva kwelenzi
Munguva yekushandiswa kwe optical lens, iyo yepamusoro ichapfekedzwa kune imwe nhanho.Iyo resin lens inogona kutora ultraviolet mwaranzi, asi panguva imwe chete, iyo lenzi inochembera uye kushanduka yero.Izvi zvinhu zvinokanganisa kutapurirana.

2. Mushonga wacho uchachinja gore negore
Nekuchinja kwezera, nharaunda yeziso uye dhigirii rekushandisa, iyo refractive yeziso remunhu yave kuchinja, saka zvinodikanwa re-optometry gore rimwe nerimwe kana gore nehafu.

Vanhu vazhinji vanofunga kuti maziso avo akaiswa.Chero bedzi magirazi e myopia asina kushata, zvakanaka kuapfeka kwemakore akati wandei.Kunyange vamwe vanhu vakwegura vane tsika ye "kupfeka magirazi kwemakore anopfuura gumi".Kutaura zvazviri, tsika iyi haina kururama.Kunyangwe iri myopia kana presbyopic magirazi, anofanirwa kuongororwa nguva nenguva uye kutsiviwa nenguva kana kusagadzikana kukaitika.Varwere venguva dzose myopia vanofanira kuchinja magirazi avo kamwe chete pagore.

Vechidiki vari munguva yekukura kwemuviri, kana vakapfeka magirazi asina kujeka kwenguva yakareba, retina ye fundus haigamuchire kukurudzirwa kwezvinhu zvakajeka, asi ichakurumidza kukura kwe myopia.Kazhinji, vechidiki vanopfeka magirazi emyopia vanofanira kuongororwa maziso avo mwedzi mitanhatu yega yega.Kana pane kuchinja kukuru kwedhigirii, zvakadai sekuwedzera kweanopfuura madhigirii makumi mashanu, kana magirazi akasakara zvakashata, anofanirawo kuchinja magirazi nenguva.

Vanhu vakuru vasingawanzoshandisa maziso avo vanofanira kuongororwa maziso avo kamwe chete pagore uye magirazi avo oongororwa kuti haana kukuvara here.Pakangove nekukwenya pane lens pamusoro, zviri pachena zvinokanganisa maitiro ayo ekururamisa optical.Magirazi e-presbyopic evakwegura anofanirawo kuchinjwa nguva dzose.Presbyopia inokonzerwa nekukwegura kwema lens.Dhigirii rekuchembera rema lens rinowedzera nezera.Ipapo iyo lens degree inowedzerwa.Vanhu vakwegura vanofanira kutsiva magirazi avo pavanenge vachitadza kuverenga mapepanhau uye maziso avo akazvimba.
