Tinoreva chiedza chinogona kuonekwa neziso remunhu sechiedza chinooneka, kureva kuti, “red orange yellow yellow blue blue blue purple”.
Zvinoenderana nezviyero zvakawanda zvenyika, chiedza chinooneka muwavelength range ye400-500 nm chinonzi blue light, inova ndiyo yavelength ipfupi uye chiedza chine simba zvakanyanya (HEV) muchiedza chinooneka.
Chiedza chebhuruu chinowanikwa kwese muhupenyu hwedu.Chiedza chezuva ndicho chikuru chechiedza chebhuruu, asi akawanda emagetsi ekugadzira magetsi, akadai semarambi eLED, flat screen TVS uye madhijitari anoratidza masikirini akadai semakomputa nenharembozha, anoburitsawo mwenje wakawanda weblue.
Zvakakosha kuziva kuti nepo HEV inoburitswa nemidziyo iyi iri diki kana ichienzaniswa neinoburitswa nezuva, nguva inopedzwa nevanhu vari pamidziyo yedhijitari iyi yakakura kudarika nguva yavanenge vachisangana nezuva.
Chiedza chebhuruu chinogona kunge chakaipa kana chakanaka kwatiri, zvichienderana nenguva yekuratidzwa, kusimba, huwandu hwewavelength uye nguva yekuratidzwa.
Parizvino, mhedzisiro yekuedza inozivikanwa vese vanotenda kuti chikuru chinokuvadza ziso remunhu ndeye pfupi-wave bhuruu mwenje pakati pe415-445nm, yenguva refu cumulative irradiation, ichakonzera kumwe kukuvadza kwemaziso kumunhu;Yakareba wavelength yebhuruu mwenje pamusoro pe445nm haingokuvadzi kumaziso emunhu, asi zvakare inoita basa rakakosha mubiological rhythm.
Naizvozvo, kuchengetedzwa kwechiedza chebhuruu kunofanirwa kuve "chaizvo", ichivharira mwenje webhuruu unokuvadza uye uchirega mwenje unobatsira webhuruu uchipfuura.
Anti-blue light glasses kubva kune yekutanga substrate absorption type (tan lens) lens kune film reflection type, ndiko kuti, kushandiswa kwefirimu layer kuratidza chikamu chechiedza chebhuruu kunze, asi kutarisa kwepamusoro kwe lens kunonyanya kuoneka;Zvino kurudzi rutsva rwelens isina ruvara rwekumashure uye yakakwira mwenje transmittance, yebhuruu ray anti-magirazi zvigadzirwa zvinogara zvichivandudzwa uye kudzokororwa.
Panguva ino, musika wakaonekwawo mamwe ziso rehove rakasanganiswa beads, shoddy zvigadzirwa.
Semuenzaniso, mamwe mabhizinesi epamhepo anotengesa magirazi ekuvharisa bhuruu kune vatengiwo zvavo.Magirazi aya anotanga kushandiswa kuvarwere vakaonekwa vaine chirwere chemacular kana vamwe varwere vanopora kubva pakuvhiyiwa kwemaziso, asi anotengeswa se "100% blue-blocking".
Iri rudzi rwemagirazi e-anti-blue light, ruvara rwemashure re lens rakanyanya kutsvuka, chiono chichakanganiswa, iyo transmittance yakaderera zvikuru asi inowedzera njodzi yekuneta kwekuona;Mwero weblue light blocking rate wakanyanya kuvharisa mwenje weblue unobatsira.
Naizvozvo, vanhu havafanirwe kukanganisika se "chigadzirwa chakanaka" nekuda kwe "medical" label.
Kuti ive nechokwadi chekuita uye mhando yezvigadzirwa zvekudzivirira zveblu-ray, muna Chikunguru 2020, chiyero chakakodzera "GB/T 38120-2019 Blu-ray yekudzivirira firimu, hutano hwakareruka uye chiedza chekuchengetedza application technical zvinodiwa" chakagadzirirwa zvigadzirwa zvekudzivirira blu-ray.
Saka, kana munhu wese ari KUSARUDZA KUDZIVIRIRA magirazi ebhuruu, anofanirwa kutarisisa chiyero chenyika.
