Ukukhanya okuluhlaza okwesibhakabhaka kukukhanya okubonakalayo kunye nobude obufutshane kunye namandla aphezulu, kwaye kufana nemitha ye-ultraviolet, ukukhanya okuluhlaza kuneenzuzo kunye nobungozi.
Ngokubanzi, izazinzulu zithi ukukhanya okubonakalayo okubonakalayo kubandakanya imitha ye-electromagnetic enobude obusuka kwi-380 nanometers (nm) kumphetho obhulowu wespectrum ukuya malunga ne-700 nm kwisiphelo esibomvu.(Ngendlela, i-nanometer yibhiliyoni enye yemitha - yimitha eyi-0.000000001!)
Ukukhanya okuluhlaza ngokuqhelekileyo kuchazwa njengokukhanya okubonakalayo ukusuka kwi-380 ukuya kwi-500 nm.Ukukhanya okuluhlaza ngamanye amaxesha kuye kwaphulwa kwakhona kube kukukhanya kweblue-violet (malunga ne-380 ukuya kwi-450 nm) kunye nokukhanya kweblue-turquoise (malunga ne-450 ukuya kwi-500 nm).
Ngoko ke, malunga nesinye kwisithathu sakho konke ukukhanya okubonakalayo kuthathwa njengokukhanya okuphezulu okubonakalayo (HEV) okanye "blue" ukukhanya.
Kukho ubungqina bokukhanya okuluhlaza kunokukhokelela kutshintsho olusisigxina lombono.Phantse konke ukukhanya okuluhlaza kudlula ngokuthe ngqo ngasemva kwiretina yakho.Olunye uphando lubonise ukukhanya okuluhlaza okwesibhakabhaka kunokunyusa umngcipheko we-macular degeneration, isifo se-retina.
Uphando lubonisa ukukhanya okuluhlaza okwesibhakabhaka kunokukhokelela ekuwohlokeni kwe-macular ezinxulumene neminyaka, okanye i-AMD.Olunye uphando lufumene ukukhanya okuluhlaza okwesibhakabhaka kubangele ukukhutshwa kweemolekyuli ezinetyhefu kwiiseli ze-photoreceptor.Oku kubangela umonakalo onokukhokelela kwi-AMD.
Kwiminyaka eliqela eyadlulayo, saphuhlisa isizukulwana sokuqala seiilensi zokuthintela ukukhanya okuluhlaza.Ngokusungula itekhnoloji kwixesha elidlulileyo, yethuiilensi zokuvala eziluhlazaziphuculwa ngokwendalo kangangoko ukuze kungabonakali.
Yethubukuthintela ukukhanyaiilensizinezihluzi ezivimba okanye ezifunxa ukukhanya okuluhlaza.Oko kuthetha ukuba usebenzisaeziilensiesxa ujonge isikrini, ngakumbi emva kobumnyama, banokunceda ukunciphisa ukuvezwa kwamaza okukhanya aluhlaza anokukugcina uphaphile kwaye ancede ekunciphiseni ubunzima bamehlo.Nangona kunjalo, abanye abantu babanga ukukhanya okuluhlaza okwesibhakabhaka kwizixhobo zedijithali akubangeli i-eyestrain.Iingxaki abantu abakhala ngazo zibangelwa kukusetyenziswa kakhulu kwezixhobo zedijithali.
