Ukukhanya okuluhlaza okwesibhakabhaka kungukukhanya okubonakalayo okukhanyayo nge-wavelength emfushane kakhulu namandla aphezulu kakhulu, futhi kufana nemisebe ye-ultraviolet, ukukhanya okuluhlaza okwesibhakabhaka nakho konke kunezingozi.
Ngokuvamile, ososayensi bathi i-spectrum ebonakalayo ebonakalayo inezindawo ezinama-electromagnetic nge-wavelengths ezisukela kuma-nanometers angama-380 (nm) ekugcineni okuluhlaza okwesibhakabhaka kokuphela kwama-700 (By the way, i-nanometer inguzigidigidi zamamitha - leyo yi-0.00000000001
Ukukhanya okuluhlaza okwesibhakabhaka ngokuvamile kuchazwa njengokukhanya okubonakalayo okusukela ku-380 kuya ku-500 nm. Ukukhanya okuluhlaza okwesibhakabhaka kwesinye isikhathi kuhlukaniswe ku-Blue-Violet Light (cishe i-380 kuya ku-450 nm) kanye nokukhanya okuluhlaza okwesibhakabhaka (cishe ama-450 kuya ku-500 nm).
Ngakho-ke, cishe ingxenye eyodwa kwezintathu yazo zonke izibani ezibonakalayo ibhekwa njenge-High-Energy ebonakalayo (HEV) noma "Blue" Light.
Kunobufakazi Book Light kungaholela ekushintsheni kombono okungapheli. Cishe konke ukukhanya okuluhlaza okwesibhakabhaka kudlula ngqo emuva kwe-retina yakho. Olunye ucwaningo lukhombisile ukukhanya okuluhlaza okwesibhakabhaka kungakhulisa ubungozi bokuwohloka kwama-macular, isifo se-retina.
Ucwaningo lukhombisa ukuvezwa kokukhanya okuluhlaza okwesibhakabhaka kungaholela ekuwohlokeni okuhlobene nobudala, noma i-AMD. Isifundo esisodwa sathola ukukhanya okuluhlaza okwesibhakabhaka kwakha ukukhishwa kwama-molekyuli anobuthi kumaseli we-Photoreceptor. Lokhu kudala ukulimala okungaholela ku-AMD.
Eminyakeni eminingana eyedlule, sakha isizukulwane sokuqala seAma-lens aluhlaza okwesibhakabhaka avimba ama-leves.Ngokuqamba ubuchwepheshe esikhathini esidlule, kwethuamalensi avinjelwe okwesibhakabhakazithuthukiswa njengemvelo ngangokunokwenzeka ukuze ingabonakali.
-KwethubUkuvinjwa Kokukhanya Kokukhanyaamalensiube nokuhlunga okuvimba noma kunciphise ukukhanya okuluhlaza okwesibhakabhaka. Lokho kusho ukuthi uma usebenzisaleziingilazi eqoqa ukukhanyaesUma ubheka isikrini, ikakhulukazi ngemuva kobumnyama, bangasiza ekunciphiseni ukubonwa kwamagagasi akhanyayo aluhlaza okwesibhakabhaka ongakugcina uvukile futhi usize ukunciphisa ubunzima bamehlo. Kodwa-ke, abanye abantu bafuna ukukhanya okuluhlaza okwesibhakabhaka kumadivayisi edijithali akubangeli i-Eyestrain. Izinkinga abantu abakhalaza ngazo zimane zibangelwa ukusetshenziswa ngokweqile kwamadivayisi edijithali.
