Isu tese tinoziva kuti yakawandisa mbozha nhare, komputa kana TV skrini inogona kuita kuti iwe uwone zvishoma.Dzimwe nyanzvi vanhu vanogona kuziva kuti chikonzero chaicho chekurasikirwa kwekuona uye myopia mwenje webhuruu unoburitswa nemagetsi skrini.
Sei zvidzitiro zvemagetsi zvine mwenje weBlue wakawandisa?Nokuti magetsi emagetsi anonyanya kugadzirwa ne LEDS.Zvinoenderana neatatu ekutanga mavara echiedza, vagadziri vazhinji vanowedzera zvakananga kusimba kwechiedza chebhuruu kuti vavandudze kupenya kwechena LED, kuitira kuti yero mwenje uwedzere zvinoenderana, uye kupenya kwechiedza chena kuchawedzera pakupedzisira.Nekudaro, izvi zvinokonzeresa dambudziko re "rambi rebhuruu rakawandisa" ratinozotsanangura gare gare muchinyorwa.
Asi chatinowanzo taura kuti mwenje weblue ipfupi kune yakakwirira simba short wave blue light.Iyo wavelength iri pakati pe415nm ne455nm.Chiedza chebhuruu mune iyi wavelength ipfupi uye ine simba repamusoro.Nekuda kwesimba rayo rakawanda, masaisai echiedza anosvika muretina uye anoita kuti masero epithelial anoumba pigment iri muretina aore.Kupera kwemasero epithelial kunokonzera kushayikwa kwezvokudya mumasero asinganzwisisi chiedza, zvichikonzera kukanganisa zvachose kwekuona.
Anti - yebhuruu mwenje lens ichaita yero yakareruka, nekuti iyo mwenje chiitiko lens inoshaya bhendi rechiedza chebhuruu, zvichienderana nechiedza chemavara matatu ekutanga.RGB (tsvuku, girini uye bhuruu) kusanganisa musimboti, mutsvuku uye girinhi musanganiswa kuita yero, ndicho chikonzero chaicho nei magirazi ekuvharira ebhuruu achitaridzika seyero isinganzwisisike.
Yechokwadi yebhuruu mwenje inodzivirira lens yekumira iyo yebhuruu laser pointer bvunzo, isu tinoshandisa yebhuruu mwenje bvunzo peni kuvhenekera bhuruu inodzivirira lens, tinogona kuona kuti mwenje webhuruu haugone kupfuura.Ratidza kuti iyi anti-blue light lens inogona kushanda.
