Magirazi ebhuruu akacheka magirazi anogona, kusvika pamwero wakati, kuve "icing pakeke" asi haana kukodzera vanhu vese. Chiremba anoti: "Vanhu vane retinal abnormality kana avo vanoda kushandisa mascreen emagetsi zvakanyanya vangafunga kupfeka magirazi eblue cut. Zvisinei, vabereki havafanirwe kusarudzablue cut light magirazikuitira vana kungodzivirira myopia."
1.magirazi ebhuruu akacheka magirazi haakwanise kunonoka kutanga kwe myopia.
Vabereki vazhinji vanoshamisika: Vanofanira kusarudza magirazi ebhuruu akachekwa evana vavo vari pedyo here? Chiedza chechisikigo chinosanganisira mavara manomwe akasiyana echiedza, nesimba rawo richiwedzera kutevedzana. Chiedza chebhuruu chinoonekwa nemeso emunhu chinoreva kureba kwemasaisai e400-500 nm. Kunyangwe zvese zviri bhuruu mwenje, wavelength iri pakati pe480-500 nm inozivikanwa seyakareba-wave bhuruu mwenje, uye iyo iri pakati pe400-480 nm inonzi short-wave bhuruu mwenje. Nheyo yemagirazi ebhuruu akachekwa mwenje ndeye kuratidza pfupi-wave yebhuruu mwenje nekupfekedza jira pane lens pamusoro kana nekubatanidza zvinhu zvebhuruu zvakachekwa mwenje mulenzi kuti utore "chiedza chebhuruu," uchiwana bhuruu yekucheka mhedzisiro.
Ongororo dzinoratidza kuti kusefa kunze kwechiedza chebhuruu hakuderedzi kuneta kwemaziso kunokonzerwa nekutarisa pamacomputer skrini, uye hapana humbowo hwakakwana hunoratidza kushanda kwayo mukudzivirira myopia muchipatara.
2.Kukuvadza kwechiedza chebhuruu chinobudiswa kubva pamagetsi emagetsi kusvika kumaziso kunogumira.
Kunyangwe mwenje webhuruu usiri iwo wakanyanya kusimba muchiedza chinooneka, ndicho chakanyanya kukonzeresa kukuvadza. Izvi zvinodaro nekuti, kunyangwe mwenje weviolet uine simba rakasimba, vanhu vanonyanya kungwarira nezvazvo. Kusiyana neizvi, chiedza chebhuruu chinowanikwa kwose kwose muzera redhijitari uye hachidzivisiki. Iyo LED mukuvhenekesa uye yemagetsi skrini inonyanya kuburitsa mwenje chena kuburikidza nebhuruu mwenje machipisi inosimudzira yero phosphor. Kupenya kwescreen, kunowedzera kujeka kweruvara, ndiko kuwedzera kwechiedza cheblue.
High-energy short-wave blue mwenje ine mukana wepamusoro wekupararira paunosangana netunhu tudiki mumhepo, zvichikonzera kupenya uye kuita kuti mifananidzo itarise pamberi pe retina, zvichikonzera kukanganisa kwekuona kwemavara. Kuratidzwa kune yakawandisa-pfupi-wave yebhuruu mwenje usati warara unogona zvakare kuvharira kugadzirwa kwe melatonin, zvichikonzera kushaya hope. Zvidzidzo zvinoratidza kuti 400-450 nm mwenje webhuruu unogona kukuvadza macula uye retina. Nekudaro, kukurukura nezvekukuvadza pasina kufunga nezveyero hakuna kufanira; saka, kuratidzwa kwedosi yechiedza chebhuruu kwakakosha.
3.Hazvina kunaka kushora mwenje wese webhuruu.
Kunyange pfupi-wave blue light ine mabhenefiti ayo; kumwe kutsvagurudza kunoratidza kuti pfupi-wave yebhuruu mwenje muchiedza chezuva chekunze inogona kuita basa mukudzivirira myopia muvana, kunyangwe iyo chaiyo nzira isiri kujeka. Chiedza chebhuruu-refu-wave chakakosha pakudzora physiological rhythm, zvichikanganisa hypothalamus's synthesis ye melatonin uye serotonin, ichipesvedzera kurongeka kwekurara, kuvandudza manzwiro, uye kusimudzira ndangariro.
Nyanzvi dzinosimbisa: "Lens yedu inosefa mwenje weblue, saka pane kusarudzablue cut light magirazi, kiyi pakudzivirira maziso edu kushandisa zvine musoro. Dzora nguva uye kuwanda kwekushandisa zvigadzirwa zvemagetsi, chengetedza chinhambwe chakakodzera panguva yekushandiswa, uye simbisa mwenje wemukati wemukati. Zvakanaka kugara uchiongororwa maziso kuti uone uye ubate nyaya dzemaziso nenguva."
blue cut light magirazi, nekuratidzira chiedza chebhuruu chinokuvadza nefirimu yakavharidzirwa pamusoro pe lens kana kubatanidza zvinhu zvechiedza cheblue cut mu lens material, inovhara chikamu chikuru chechiedza chebhuruu, nokudaro zvichigona kuderedza kukuvadzwa kwayo kunoramba kuripo pameso.
Uyezve, magirazi ebhuruu akacheka mwenje anogona kuwedzera kusiyanisa kweziso, kuvandudza basa rekuona. Ongororo yakaitwa kuChina yakaratidza kuti mushure mekunge vanhu vakuru vapfeka malenzi eblue cut kwechinguva, kusiyanisa kwavo kwakasiyana kumadaro akasiyana uye pasi pemwenje wakasiyana-siyana uye kupenya kwakavandudzika. Kune varwere vari kuita retinal photocoagulation nekuda kwechirwere cheshuga retinopathy,blue cut light magiraziinogona kuwedzera post-operative yekuona kunaka. Kune avo vane dry eye syndrome, kunyanya avo vanoshandisa makomputa kana nharembozha zvakanyanya, kupfeka magirazi ebhuruu akacheka magirazi anogona kuvandudza zvakanyanya-kwakagadziriswa kuona acuity uye kusiyanisa senitivity kune dzakasiyana siyana.
Kubva pakuona uku, magirazi ebhuruu akacheka mwenje zvechokwadi chishandiso chinobatsira chekudzivirira maziso.
Mukupedzisa,optical lens vagadzirivakapindura zvine hungwaru kukuwedzera kwekuda kweblue cut lenses, vachiratidza kuzvipira kwavo kuhutano hwemaziso uye hunyanzvi hwekuvandudza tekinoroji. Nekubatanidza tekinoroji yekusefa yeblue yemhando yepamusoro muzvigadzirwa zvavo, vagadziri ava havasi kungogadzirisa zvinonetsa mutengi nezve dhijitari yeziso asi varikumisa mazinga matsva mumapfekero emaziso ekudzivirira. Uku kusimukira kunosimbisa kuzvipira kweindasitiri yemaziso mukusimudzira kunyaradzwa kwekuona uye kuchengetedza chiono munyika yedu iri kuwedzera yedhijitari-centric.
