Uko ikirere gishyuha, ushobora gusanga umara igihe kinini hanze. Kugira ngo wirinde ikirere, kwambara indorerwamo z'izuba ni ngombwa!
Guhura n'imiraba y'izuba n'ubuzima bw'amaso
Izuba ni ryo soko nyamukuru ry'imirasire ya Ultraviolet (UV), ishobora kwangiza amaso yawe. Izuba ritanga ubwoko butatu bw'imirasire ya UV: UVA, UVB na UVC. UVC yinjizwa n'ikirere cy'Isi; UVB irafunze igice; imirasire ya UVA ntabwo iyungururwa bityo ishobora kwangiza amaso yawe cyane. Nubwo hari ubwoko butandukanye bw'indorerwamo z'izuba, si indorerwamo zose zirinda imirasire ya UV - ni ngombwa guhitamo lenses zirinda imirasire ya UV na UVB mu gihe uguze indorerwamo z'izuba. Indorerwamo z'izuba zifasha kwirinda izuba hafi y'amaso rishobora gutera kanseri y'uruhu, cataracts n'iminkanyari. Indorerwamo z'izuba nazo zagaragaye ko ari uburinzi bwiza bwo kureba mu gihe utwaye imodoka kandi zitanga ubuzima bwiza muri rusange no kurinda imirasire ya UV mu maso yawe hanze.
Guhitamo Indorerwamo z'Izuba Zikwiye
Nubwo imiterere n'uburyohe bifite uruhare runini mu guhitamo indorerwamo z'izuba zikwiye, indorerwamo zikwiye nazo zishobora kugira itandukaniro rinini.
- Irangilentile: Imirasire ya UV iboneka umwaka wose, cyane cyane mu mezi y'izuba. Kwambara indorerwamo z'izuba zirinda 100% bya UV ni bumwe mu buryo bworoshye bwo kugabanya ibyago byinshi ku buzima bw'amaso. Ariko nyamuneka menya ko indorerwamo z'izuba zijimye zidatanga uburinzi bwinshi mu buryo bwikora. Shaka uburinzi 100% bya UVA/UVB mu gihe uguze indorerwamo z'izuba.
- Ikirahuri gifite imiterere ya polarized:Amabara atandukanye y'indorerwamo z'izuba ashobora kuba ingirakamaro ku bikorwa bitandukanye. Indorerwamo z'izuba zikozwe muri polarized ntizishobora kukurinda imirasire ya UV gusa, ahubwo zinafasha kugabanya urumuri n'ishusho ku buso nk'amazi. Bityo rero, indorerwamo z'izuba zikozwe muri polarized zizwi cyane mu gutwara ubwato, kuroba, kugendera ku igare, gukina golf, gutwara imodoka n'ibindi bikorwa byo hanze.
- Irangi ry'indorerwamo riboneka kuri lensi ifite ibara ry'umutuku n'iry'umutuku:Indorerwamo zirinda imirasire y'izuba n'imirabyo hamwe n'amabara agezweho y'indorerwamo.
Kurinda izuba ni ingenzi umwaka wose kandi kwangirika kwa UV birakomeza kwiyongera mu buzima bwawe. Kwambara indorerwamo z'izuba buri munsi iyo usohotse mu muryango ni uburyo bwiza kandi bworoshye bwo kubungabunga ubuzima bw'amaso yawe.
