Magirazi ebhuruu anogona, kusvika pamwero wakati, kuva "icing on the cake" asi haana kukodzera vanhu vese. Kusarudza magirazi asingaoni kunogona kutokanganisa. Chiremba anoti: "Vanhu vane retina isina kunaka kana avo vanoda kushandisa masikirini emagetsi zvakanyanya vanogona kufunga kupfeka magirazi ebhuruu. Zvisinei, vabereki havafaniri kusarudzamagirazi emwenje ebhuruu akachekwavana kungodzivirira myopia.
1.Magirazi ebhuruu akachekwa haagoni kunonotsa kutanga kwe myopia.
Vabereki vazhinji vanobvunza kuti: Vanofanira kusarudza magirazi ebhuruu anochekwa nevana vavo vanoona zviri pedyo here? Chiedza chechisikigo chine mavara manomwe akasiyana echiedza, simba rawo richikwira zvichiteerana. Chiedza chebhuruu chinoonekwa nemaziso evanhu chinoreva kureba kwemarefu e400-500 nm. Kunyangwe chiri chiedza chebhuruu chose, kureba kwemarefu kuri pakati pe480-500 nm kunozivikanwa sechiedza chebhuruu chine mafungu marefu, uye icho chiri pakati pe400-480 nm chinonzi chiedza chebhuruu chine mafungu mapfupi. Nheyo yemagirazi ebhuruu anochekwa ndeyekuratidza chiedza chebhuruu chine mafungu mapfupi nekuputira pamusoro pelenzi kana nekuisa zvinhu zvechiedza chebhuruu mulenzi kuti itore "chiedza chebhuruu," zvichiita kuti ikwanise kuchekwa nebhuruu.
Ongororo dzinoratidza kuti kubvisa chiedza chebhuruu hakurerutsi kuneta kwemaziso kunokonzerwa nekutarisa pamakombiyuta, uye hapana humbowo hwakakwana hunoratidza kushanda kwaro mukudzivirira myopia mukurapa.
2. Kukuvadzwa kwechiedza chebhuruu chinoburitswa kubva kumasikirini emagetsi kuenda kumaziso kwakaganhurirwa.
Kunyangwe chiedza chebhuruu chisiri icho chinonyanya kusimba muchiedza chinoonekwa, ndicho chinonyanya kukonzera njodzi. Izvi zvinodaro nekuti, kunyangwe chiedza cheviolet chine simba rakawanda, vanhu vanongwarira zvakanyanya nezvazvo. Kusiyana neizvi, chiedza chebhuruu chiripo nguva yedhijitari uye hachidzivisiki. LED iri mumwenje uye masikirini emagetsi inonyanya kuburitsa chiedza chichena kuburikidza nemachipisi echiedza chebhuruu anokurudzira phosphor yeyero. Kana skrini yakajeka, ruvara rwacho rwakanyanya kujeka, simba rechiedza chebhuruu rinokwira.
Mwenje webhuruu une simba guru une mukana wakakura wekupararira kana wasangana netunhu tudiki mumhepo, zvichikonzera kupenya uye zvichiita kuti mifananidzo ionekwe pamberi pe retina, zvichikonzera kutsauka kwekuona mavara. Kuratidzwa nechiedza chebhuruu chine mafungu mapfupi usati warara kunogonawo kudzivirira kuburitswa kwe melatonin, zvichikonzera kushaya hope. Zvidzidzo zvinoratidza kuti chiedza chebhuruu che400-450 nm chinogona kukuvadza macula ne retina. Zvisinei, kukurukura nezvekukuvadza pasina kufunga nezvemuyero wacho hazvina kukodzera; saka, mwero wekushandiswa kwechiedza chebhuruu wakakosha.
3. Hazvina kunaka kushora chiedza chebhuruu chose.
Kunyangwe chiedza chebhuruu chine mafungu mapfupi chine zvachinobatsira; kumwe kutsvagurudza kunoratidza kuti chiedza chebhuruu chine mafungu mapfupi muzuva rekunze chinogona kubatsira kudzivirira myopia muvana, kunyange hazvo nzira yacho isina kujeka. Chiedza chebhuruu chine mafungu marefu chakakosha pakudzora rhythm yemuviri, zvichikanganisa kugadzirwa kwe melatonin ne serotonin mu hypothalamus, zvichikanganisa kurongeka kwekurara, kuvandudza mafungiro, uye kuvandudza ndangariro.
Nyanzvi dzinosimbisa kuti: "Lenzi yedu inosefa chiedza chebhuruu, saka pane kusarudzamagirazi emwenje ebhuruu akachekwa, chinhu chikuru chekudzivirira maziso edu kushandisa zvine mwero. Dzora nguva uye nguva yekushandisa zvigadzirwa zvemagetsi, chengetedza daro rakakodzera panguva yekushandisa, uye chengetedza chiedza chiri pakati nepakati mumba. Zvakanakisisa kugara uchiongororwa maziso kuti uone uye ugadzirise matambudziko emaziso nenguva."
magirazi emwenje ebhuruu akachekwa, nekuratidza chiedza chebhuruu chine njodzi nefirimu rakaputirwa pamusoro perenzi kana kuisa zvinhu zvechiedza chebhuruu zvakachekwa mugirazi, zvinovhara chikamu chakakura chechiedza chebhuruu, nokudaro zvichigona kuderedza kukuvara kwacho kunoramba kuchiitika kumaziso.
Uyezve, magirazi echiedza chebhuruu anogona kuwedzera kunzwisiswa kwemaziso, zvichivandudza mashandiro ekuona. Ongororo yakaitwa kuChina yakaratidza kuti mushure mekunge vanhu vakuru vapfeka magirazi echiedza chebhuruu kwenguva yakati, kunzwisiswa kwavo kwekuona kusinganzwisisike padaro rakasiyana uye pasi pemamiriro akasiyana-siyana echiedza nechiedza kwakavandudzika. Kune varwere vari kubatwa neretinal photocoagulation nekuda kwechirwere cheshuga retinopathy,magirazi emwenje ebhuruu akachekwazvinogona kuwedzera kunaka kwekuona mushure mekuvhiyiwa. Kune avo vane dry eye syndrome, kunyanya avo vanoshandisa makombiyuta kana nharembozha zvakanyanya, kupfeka magirazi ebhuruu kunogona kuwedzera kugona kuona zvakanaka uye kunzwisiswa kwemavara akasiyana-siyana.
Kubva pamaonero aya, magirazi ebhuruu anobatsira zvikuru pakudzivirira maziso.
Mukupedzisa,vagadziri vemagirazi emazisovakapindura neunyanzvi kuwedzera kwekudiwa kwemalenzi ebhuruu, zvichiratidza kuzvipira kwavo kuhutano hwemaziso uye hunyanzvi hwetekinoroji. Nekushandisa tekinoroji yepamusoro yekusefa mwenje webhuruu muzvigadzirwa zvavo, vagadziri ava havasi kungogadzirisa zvinonetsa zvevatengi nezvedambudziko remaziso edhijitari chete asiwo vari kuisawo mwero mutsva muzvipfeko zvekudzivirira maziso. Kuvandudzwa uku kunosimbisa kuzvipira kweindasitiri yemaziso mukuvandudza kunyaradzwa kwekuona uye kuchengetedza maonero munyika yedu iri kuramba ichitarisa padhijitari.
