Magirazi ebhuruu anovharira magirazi ave kuwedzera mukurumbira mumakore achangopfuura, nevanhu vazhinji vachiaona senge mhinduro inogona kuderedza kushushikana kwemaziso uye kunatsiridza kunaka kwekurara.Kubudirira kwemagirazi aya inyaya yekufarira uye yakafuridzira zvidzidzo zvakasiyana uye nharo.Muchinyorwa chino, tichaongorora mabhenefiti angangove eblue light blocking glasses, sainzi kuseri kwawo, uye zvimwe zvinhu zvekurangarira kana uchiashandisa.Chiedza chebhuruu isimba repamusoro-soro, pfupi-wavelength mwenje unoburitswa nedhijitari skrini, mwenje we LED, uye zuva.Kuratidzwa kwechiedza chebhuruu kubva kumasikirini, kunyanya husiku, kunovhiringa kutenderera kwemuviri kumuka-kumuka nekudzvinyirira kugadzirwa kwe melatonin, hormone inodzora kurara.Pamusoro pezvo, kuratidzwa kwenguva refu kuchiedza chebhuruu kunosanganiswa nedhijitari yeziso dhiri, mamiriro anoonekwa nekusagadzikana kweziso, kuoma, uye kuneta.Magirazi ebhuruu akagadzirirwa kusefa kunze kana kuvharira imwe mwenje webhuruu, nokudaro kuderedza huwandu hwechiedza chebhuruu chinosvika mumaziso ako.Mamwe malenzi akagadzirwa kuti anange mafungu anokuvadza echiedza chebhuruu, nepo mamwe achigona kuve nekusefa kwakawanda.Pfungwa iri kuseri kwemagirazi aya ndeyekudzikamisa zvingangove zvakashata zvinokonzeresa mwenje webhuruu pahutano hweziso uye maitiro ekurara.Zvidzidzo zvakati wandei zvakaongorora mhedzisiro yeblue light blocking magirazi pakuneta kwemaziso uye kunaka kwekurara.
Chidzidzo che2017 chakabudiswa muJournal of Adolescent Health chakawana kuti vatori vechikamu vaipfeka magirazi eblue-light blocking pavanenge vachishandisa michina yedhijitari vakawana zvakanyanya kuderedzwa zviratidzo zvekunetsekana kwemaziso zvichienzaniswa nevatori vechikamu vasina kupfeka magirazi.Imwe ongororo yakabudiswa muna 2017 mujenari Kurara Hutano yakaratidza kuti kupfeka magirazi ebhuruu-anovharira magirazi usiku kunogona kuvandudza kunaka kwekurara nekuwedzera melatonin mazinga uye kuderedza nguva yainotora kurara.Nekune rimwe divi, zvimwe zvidzidzo zvakakanda kusahadzika pakubudirira kwese kweblue light blocking glasses.Chidzidzo che2018 chakaburitswa mujenari Ophthalmology uye Physiological Optics yakagumisa kuti kunyangwe kuratidzwa kwechiedza chebhuruu kuchigona kukonzera kusagadzikana kwekuona, humbowo hwekuti bhuruu kusefa lenses kunogona kuderedza zviratidzo izvi hazvigoneke.Saizvozvowo, ongororo ya2020 yakaburitswa muCochrane Database yeSystem Ongororo yakawana humbowo husina kukwana hunotsigira kushandiswa kwemagirazi eblue ekusefa magirazi kuderedza dhijitari yeziso.Kunyangwe mhedzisiro yekutsvagisa yakasanganiswa, vanhu vazhinji vanorondedzera kuvandudzwa kwemeso mukunyaradza kweziso uye kunaka kwekurara mushure mekupfeka magirazi ekuvharisa chiedza chebhuruu muhupenyu hwavo hwezuva nezuva.Zvakakosha kuziva kuti mhinduro yemunhu kumagirazi aya inogona kusiyana zvichienderana nezvinhu zvakaita senguva yekuratidzwa skrini, kubatwa nemaziso emunhu, uye maitiro ekurara aripo.Paunenge uchifunga nezvekugona kushanda kwebhuruu chiedza chekuvhara magirazi, zvakakosha kunzwisisa kuti magirazi aya haasi mhinduro imwe chete.Zvinhu zvakadai semhando yemalenzi, iwo wavelengths chaiwo echiedza chebhuruu chakanangwa, uye misiyano yemunhu mufiziology yeziso uye kunzwisiswa kwechiedza zvese zvinokanganisa zvinoonekwa mhedzisiro yekupfeka magirazi aya.Pamusoro pezvo, kutora nzira yakazara yehutano hwemaziso uye hutsanana hwekurara kwakakosha.Pamusoro pekushandisa magirazi ekuvharisa chiedza chebhuruu, kutora nguva dzese skrini, kugadzirisa kupenya kwescreen uye masisitimu ekusiyanisa, kushandisa mwenje wakakodzera, uye kudzidzira tsika dzakanaka dzekurara zvinhu zvakakosha zvekuchengetedza hutano hwemaziso uye kukurudzira kurara kwakazorora.
Zvese mune zvese, nepo humbowo hwesainzi pamusoro pekushanda kwechiedza chebhuruu chinovharira magirazi hachikodzeri, pane kukura kutsigirwa kwekugona kwavo kuderedza kushushikana kwemaziso uye kugadzirisa kurara mune vamwe vanhu.Kana iwe ukasangana nekusagadzikana kubva kwenguva yakareba skrini kana uchinetseka kurara mushure mekushandisa dhijitari, zvingave zvakakosha kufunga nezvekuyedza bhuruu kuvharira magirazi.Nekudaro, kushandiswa kwavo kunofanirwa kutariswa sechikamu chehurongwa hwekuchengetedza maziso uye hutsanana hwekurara, uye yeuka kuti mhinduro dzega dzingasiyana.Kubvunzana nenyanzvi yekuchengeta maziso kunogona kupa nhungamiro yakasarudzika yekubatanidza magirazi ekuvharisa chiedza cheblue muhupenyu hwako hwezuva nezuva.
