Ziso rako rechiremba rinogona kunge rinokurudzira magirazi ehupamhi kuitira kudzivirira meso ako kubva kune zvinokuvadza zvinokonzera masikati machena anobudiswa nezuva, sezvo chiedza che ultraviolet chinogona kuita kuti kuve nekunyanya kwekemikari kenza, cataract, pinguecula, uye pterygium. Asi zvakadini newavelength yebhuruu yechiedza? Chiedza chebhuruu chinogona kukonzera kukuvadza kwehutachiona kumeso, uye chinogona kuita basa rinokosha mukukonzera kufanana kwehutano hwe macular, izvo zvinogona kutungamirira pakuona kurasikirwa kwemaonero.
Sezvo uchidzivirira meso ako kubva kune zvinokuvadza zve ultraviolet chiedza, iwe unofanira kunge uri kuvadzivirira kubva kuchiedza chebhuruu here?
Basics
Maziso ako anononoka kune boka rakamanikidzwa remagetsi anonzi "chiedza chinowanikwa." Visible chiedza-chiedza chinogona kuonekwa neziso revanhu-chinosanganisira mawindo emhando dzakasiyana. Chiedza chebhuruu chine nguva yakareba chaizvo uye inoonekwa neziso revanhu. Kwete chete inopa kujekesa kwekutanga kwepasi redu, chiedza chebhuruu chinobatsirawo kuwedzera manzwiro ehupenyu. Asi kuonekwa kune zvakawanda zvechiedza chebhuruu zvinogona kuva zvinokuvadza kumeso.

Izvo zvinoshandiswa nemagetsi zvemagetsi zviri kushandiswa mazuva ano, zvakadai sefoni, mahwendefa, uye makombiyuta emakombiyuta, zvakanyanya kuwedzera kusvibiswa kwatinoita bhuruu. Chimwe chitubu chechiedza chebhuruu inyanzvi yekugadzira magetsi semafuta e-fluorescent light bulbs uye magetsi e LED. Kutsvakurudza kwakagadzirisa kuti lens mukati meziso, uye iyo pigment iri kumashure kweziso, inopa kudzivirirwa kune chiedza chebhuruu.
Asi izvi zvinogadzirisa chete zvinotora kwenguva pfupi yekutsvaga kuchena kwechiedza chebhuruu, uye masikati masikati.
Chiedza chebhuruu uye Macular Degeneration
Zvichida dambudziko guru rekuchena kwebhuruu ndiyo iyo inobatanidzwa mukusimbiswa kwehupenyu hunokonzerwa nemakore akawanda , zvikurukuru mufananidzo wemufananidzo-oxidation.
Vanhu vane ngozi yakanyanya yechirwere vanofanira kuchengetedza maziso avo kubva pakuchenesa kwebhuruu. Vamwe vanachiremba vanokurudzira halogen magetsi senzira kune dzimwe mhando dzechiedza.
Munguva ichangopfuura, kambani inonzi Eye Solutions yakagadzira chigadzirwa chinotibatsira kutidzivirira pakuchenesa kwebhuruu-kwete kwete kunze, asiwo mukati. Iyo lens inonzi Blu-Tech lens uye ine pigment iyo inosvibisa chiedza chebhuruu isingabatsiri ruvara rwemavara. Izvi zvingava sarudzo huru kune vanhu vane macular degeneration kana avo vari pangozi yekuvandudza chirwere. Izvo zvinogonawo kukosha kune vanhu vane chirwere checataract sezvo intraocular lenses inowanikwa munguva yekuvhiyiwa kwechirita inogona kunge isina kudzivirirwa kwakanyanya pamusoro pechiedza chebhuruu.
Chiedza chebhuruu uye Melatonin
Melatonin inonzi hormone yehope mumitumbi yedu inobatsira kudzora chitarisiko chedu circadian rhythms. Meso edu ane zvinyorwa zvine chinyorwa chinonzi photopigment chinonzi melanopsin chinoshungurudzika kune chiedza chebhuruu. Aya masero anopa ruzivo kumitumbi yedu inotungamirira pfungwa dzedu masikati neusiku. Chiedza chebhuruu chave chichiratidzwa nevatsvakurudzi kuti chaizvoizvo kuwedzere kufarira uye mafungiro mukati mezuva, asi kusingagumi kwenguva refu kune chiedza chebhuruu usiku kunogona kupa mharidzo muuropi hwedu kuderedza kuchengetedzwa kwe melatonin, iyo inotiudza kuti tike uye tive takangwarira-zvingangovhiringidza isu circadian rhythm.
Zvaunofanira Kuziva
Kunyange zvazvo chiedza chebhuruu chave chisingabatanidzwa nehuwandu hwehutano hwekenza, chirwere cheshuga, chirwere chemoyo, kuneta, uye kukanganisa mumutauro we circadian, inoramba iine chikamu chinokosha chezvisikwa zvepanyama uye zvechigadzirwa. Bvunza optometrist yako kana ophthalmologist kana iwe uri pangozi yemaziso maziso angave akabatanidzwa nehutukutu hwemhepo. Izvi zvinowanzobatanidza kubvunzurudzwa kwenhoroondo yemhuri yako uye kuongororwa kwemaziso ekudzoka kweziso.
Sezvo nguva dzose, chengetedza mazano anotevera mupfungwa nokuda kwekudzivirira kweziso kwe UV:
- Chiremera chakawedzerwa zuva kuvira kana zvichibvira.
- Pfeka zvipfeko zvakapetwa mukati mezuva.
- Funga nezvemarara ekunyunguduka kwemalaanin pigmented. Kunyange zvazvo zvingakonzera kuchinja kwemavara maonero, inoderedza pasi kunze kwebhuruu chiedza.
- Deredza kuderedzwa kwechiedza chebhuruki nekuchengeta madivhidhijiti kubva muimba yekurara.
- Deredza mutambo wekutsvaga paIndaneti manheru kuti uderedze chiedza chine ruvara rwebhuruu kubva pakombiyuta yako uye zvingashandurwa mu circadian rhythm.
