Kuyini ukukhanya okuluhlaza okwesibhakabhaka?
ILanga lisigeza nsuku zonke ngokukhanya, okungenye yezinhlobo eziningi zemisebe kagesi, kanye namaza omsakazo, ama-microwave kanye nemisebe ye-gamma.Asikwazi ukubona ingxenye enkulu yala maza amandla egeleza emkhathini, kodwa singawalinganisa.Ukukhanya okubonwa amehlo abantu, njengoba kugxuma ezintweni, kunobude obungamaza obuphakathi kwama-nanometres angama-380 no-700.Ngaphakathi kwale spectrum, ukusuka kokuluhlaza kuya kokubomvu, ukukhanya okuluhlaza okwesibhakabhaka kudlidliza cishe ngobude obuphansi kakhulu beza (400 kuya ku-450nm) kodwa cishe amandla aphezulu kakhulu.
Ingabe ukukhanya okuluhlaza okwesibhakabhaka okuningi kungalimaza amehlo ami?
Njengoba ingaphandle elihle lisinikeza ukuchayeka kwethu okwedlulele ekukhanyeni okuluhlaza okwesibhakabhaka, sesizokwazi manje ukuthi ukukhanya okuluhlaza bekuyinkinga yini.Sesikushilo lokho, ukugqolozela ukukhanya okuluhlaza okuphansi kwezinga eliphansi, ngokungacwayizi, esikhathini esiningi samahora ethu okuvuka, kuyinto entsha uma kuqhathaniswa, futhi i-digital eyestrain isikhalazo esivamile.
Kuze kube manje abukho ubufakazi bokuthi ukukhanya okuluhlaza okwesibhakabhaka okuvela kumadivayisi kuyicala.Abasebenzisi bekhompyutha bavame ukucwayiza ngokuphindwe kahlanu kunokuvamile, okungase kubangele amehlo omile.Futhi ukugxila kunoma yini isikhathi eside ngaphandle kwekhefu kuyindlela yokubuka amehlo akhathele.
Ungayilimaza i-retina uma ukhomba ukukhanya okuluhlaza okwesibhakabhaka okuqinile isikhathi eside, yingakho singabheki ngqo eLangeni noma kumathoshi e-LED.
Uyini udayi omunca ukukhanya okwesibhakabhaka?
Ukulimala Kokukhanya Okuluhlaza okwesibhakabhaka: Ukukhanya okuluhlaza okwesibhakabhaka kungase futhi kubangele ukwethuka okungaba khona nezimo ze-retinal, njengokuwohloka kwe-macular.
Izibambisi zokukhanya eziluhlaza okwesibhakabhaka ezisetshenziswa kumalensi engilazi noma izihlungi zinganciphisa ukukhanya okuluhlaza futhi zivikele amehlo ethu.
