Sviviolet radiation kubva kuzuva inogona kukonzera kukuvadza kwemaziso ako sezvaunenge uchiita - asi iwe unogona kudzivirira zvawakaratidzwa nokupfeka magirazi ezuva nezuva, kunyange mumakore ekunze. Hezvino izvo zvaunoda kuziva pamusoro pokusarudza magirazi akanaka, kuchengetedza chirwere chezera rekare uye mamwe matambudziko eziso munguva.
UV Radiation uye Yei Yekare
Sezvatinokura, maziso edu anotarisana nehupenyu hunoita kuti zvinetso zvekuona uye zvirwere zvemaziso zvakadai sezera rinosangana nehutachiona uye glaucoma .
Ultraviolet chiedza kubva kunezuva inotakura miviri miviri yemirasiyo, UVA , uye UVB rays (iyo inokonzerawo photoaging uye kukakavara kweganda redu). Sezvo UV chiedza ichiwedzera simba kupfuura chiedza chinooneka, inogona kuita kukuvadza kwemaziso edu. Sezvatinokura, mungozi inongova nenguva yakawanda yekuunganidza: cataract, (cloudiness ye lens) somuenzaniso, inotendwa inokonzerwa nemakore akawanda ekuratidzwa kune chiedza chezuva.
Magirazi egorosi akagadzirirwa kubvisa 100% yeUVA uye UVB rays achadzivirira maziso ako pamusoro pekuparara kwekuwedzera.
Rino Rima Rima Matter?
Kunyange zvazvo masikati machena angaita seanoita kudzivirirwa kwakanyanya, rima iro lens rinosanganisa chiedza chinooneka, kwete ultraviolet chiedza.
Natalie Hutchings, Associate Purofesa muYunivhesiti yeWestern's School of Optometry uye Vision Science, inoti lenzi dzemafi dzinogona kuita kuti mwana weziso rako awedzere kubvumira mune imwe chiedza, zvichiita kuti kudzivirirwa kweUV kuve kwakakosha zvikuru.
"Dhigi re rima uye lendende ruvara kana tint hazvizi izvo zvinodzivirira meso ako," anonditaurira. "Zvakakosha kusarudza magirasi anovhara 100% yose yeVU chiedza, zvose UVA uye UVB.Ukudzivirirwa kunogona kuva basa remashoko magirazi ayo akaumbwa, kuwanda kwezvinhu, kana kuti angave akapfeka lens - kunyange mumapirisi asina chero ruvara kana kutora zvachose.
Ndiko kuvhara kweVV 100% iwe unofanirwa kutarisa pane zvakanyorwa, sezvo iwe usingakwanisi kutaura kana vanezvo, kungoona mairazi. "
Mazano Okusarudza Magirazi Akanakisisa Okudzivirira Kutapukisa uye Zvimwe Maziso Emaziso
Maererano neAmerican Academy of Ophthalmology (AAO), magirazi akanaka anopa:
- 100% UV kudzivirirwa
- High optical quality (lenzi haina kusununguka pakugadzira zvakashata semabhuru kana mazaya anogona kunetsa maziso ako
- Zvinyorwa zvinopikisa lens
- Chirongwa chikuru chinopa huwandu hwekuona kwemaziso
Mukuwedzera, tora magirazi ezuva rakanaka uye unokodzera chiso chako zvakanaka, nokuti iwe unenge uchida kuvapfeka. Hutchings inoratidza kuti vakwegura vakuru vangave vachida mapuranga makuru, akasimba ayo ari nyore kubata neminwe yeArthritic.
Kubudirira kwePolarized Lenses
Hutchings anoti lens polarized inoshanda muchiedza chinoonekwa (kwete UV rays), nekudzima kunze kwechiedza chinenge chichiratidzwa kunze kwechando chinopenya sechando, mvura kana mumigwagwa inopisa. Funga nezvemazimbe emapurisa kana iwe uchikwira, ugare pedyo nemvura, kana kuti uvawanire vakasununguka pavanenge vachifambisa. Kunyange zvazvo majekisi aya kazhinji anodhura, unogona kuwana iwe unofarira ivo sezvaunokura.
Paunofanira kupfeka magirazi edzivirira kuchengetedza maziso ako
IAAO inokurudzira kupfeka magirazi egirasi chero nguva iwe uri panze, kunyanya muzhizha, apo uwandu hwemazuva ano hutatu humwe humwe hwemwe nguva dzegore.
Mukuwedzera, iwe unofanirwa kuchenjerera kupfeka magirazi egirasi kana uri pamvura kana muchando, apo magetsi matsva anooneka.
Vakuru vakuru vangawana kuti vanoda kupfeka magirazi ezvisikwa kakawanda kupfuura zvavaimboita, anodaro Natalie Hutchings, nokuti chiedza chinopfuura nepine cornea uye lens chinopararira kune imwe huru muziso rekwegura. Izvi zvinopararira zvinogona kuvhiringidza uye zvinoshungurudza, asi zvinoderedzwa nekushandiswa kwezviedza zvemasikati, zvikurukuru zvikuru zvinodzivirira chiedza chinouya kubva kumativi.
Kupfeka Magirazi Makirasi Mushure meCataract Surgery
Munguva yekuvhiyiwa kwechirwere , imwe nhengo inonzi intraocular lens (IOL) inoiswa kuti ishandise nzvimbo yekare yegore.
Yakawanda yemazino epraocular ikozvino inotora chiedza che UV. Kana iwe wakanga uine chirwere chako chechipatara nguva yapfuura yapfuura, lens yako ingasatora chiedza che UV, uye iwe unofanirwa kupfeka magirazi eguru anopa izvozvo kudzivirirwa. IAOO inokurudzira kunyange vanhu vane majekiseni ekuvhara UV mushure mekuvhiyiwa kwechirwere vanovhara magirazi edziviriro.
Dzimwe Nzira Dzokudzivirira Maziso Ako Kubva Kuzuva
Magirazi egorosi anopa nzira imwe chete yekudzivirira kwekwegura kwemaziso. Utano Canada nedzimwe nhengo dzinopawo zano rekupfeka vhegi kana kuti yakakura-shanho kana iwe uri panze uye kudzivisa nguva dzezuva rakajeka uye rakanyanyisa, zvakadai sezuva rezhizha pakati peawa 11 dzemakore ne4 masikati (apo tsamba yeVV iripamusoro ).
