Ophthalmologists vanokurudzira kuti unofanira kugara wakapfeka magirazi ezuva kudzivirira maziso ako;Izvi zvinodaro nekuti mboni yeziso redu (lenzi) iri nyore kwazvo kutora mwaranzi yeultraviolet, uye kukuvadzwa kwemwaranzi yeultraviolet kune maitiro maviri akatanhamara:

1.Kukuvadza kwemirairo ye ultraviolet kuchaunganidza.Sezvo ultraviolet chiedza chiri chiedza chisingaoneki, zvakaoma kuti vanhu vazvione intuitively.

2.Kukuvadza kwemirairo ye ultraviolet kumaziso hakugoneki, ndiko kuti, haigoneki.Zvakadai se: kuvhiyiwa kwecataract kunogona kungotsiviwa ne-intraocular lenses.Kukuvara kwenguva refu kweziso kunogona kutungamira kukuvadzwa kwe cornea uye retina, kuvharika kwe lens kusvika cataract yaitika, zvichikonzera kukuvara zvachose kwekuona.

Sezvo kukuvadzwa kwemirairo ye ultraviolet kumaziso kusingaoneki, haigoni kunzwika pakarepo.Kana iwe usingapfeki magirazi, haunzwe kunyanya kugadzikana.Zvinongoreva kuti maziso ako haanyanyi kutarisisa kuchiedza chinooneka (sekupenya kupenya, kupenya, uye kupenya kwechiedza)., uye haigone kudzivirira kukuvara kweUV.

Ko kusviba kwemagirazi ezuva, ndiko kuri nani kuvharisa UV?
