Yintoni ukukhanya eluhlaza okwesibhakabhaka kwaye kutheni kufuneka uthenge iilebhu ze-blocker eluhlaza?

Isibane esiluhlaza sisikhanyiso esibonakalayo esibonakalayo esinamaza amafutshane kunye namandla aphezulu, kwaye afana ne-ultraviolet rays, ukukhanya oluhlaza okwesibhakabhaka kuneezibonelelo zombini kunye neengozi.

Ngokubanzi, izazinzulu zithetha i-sloctrum ebonakalayo equka imitha ye-elektromagnetic kunye ne-javenets esuka kwi-380 i-nanometers (NM) kwi-Bloctures eblowu kwi-700 nm kwisiphelo esibomvu. (Ngendlela, i-nanometer yenye yebhiliyoni yemitha-yi-0.000000001:)

Ukukhanya okublowu ngokubanzi kuchazwa njengokukhanya okubonakalayo ukusuka kwi-380 ntm. Ukukhanya okublowu ngamanye amaxesha kuqhekeke ngakumbi kwi-Blue-violet ukukhanya (phantse i-380 ukuya kwi-450 NM) kunye ne-NM-Turquoise Short-Turquoise (phantse i-450 NM).

Ke, malunga nesinye kwisithathu sayo yonke ukukhanya okubonakalayo kuthathwa njengezinamandla ezibonakalayo (hev) okanye "oluhlaza okwesibhakabhaka.

Kukho ubungqina bloby oluhlaza okwesibhakabhaka kunokukhokelela kuguquko olusisigxina. Phantse konke ukuqaqamba okuluhlaza okwesibhakabhaka ngqo kumqolo we-retina yakho. Olunye uphando lubonakalisile ukukhanya oluhlaza okwesibhakabhaka lunganyusa umngcipheko wokuthathwa kwemali, isifo se-retina.

Uphando lubonisa ukubonakaliswa okuncinci oluhlaza okwesibhakabhaka kunokukhokelela ekuthambekeni kwe-MACELINE, okanye i-AMD. Isifundo esinye sifumene ukukhanya okuluhlaza okwesibhakabhaka kuphelelwe ukukhululwa kweemolekyuli zetyhefu kwiiseliptortor. Oku kubangela umonakalo onokukhokelela kwi-AMD.

Kwiminyaka eliqela eyadlulayo, sahlahlisa isizukulwana sokuqalaI-bloble yokukhanya eluhlaza okwesibhakabhaka.Ngobuchule betekhnoloji kwixesha elidlulileyo, bethuI-block eluhlaza okwesibhakabhakabaphuculwe ngokwendalo kangangoko kunokwenzeka ukuze ingabonakali.

Bethubukukhanya ukukhanyaiilensiYiba neefilitha ezibhloka okanye i-verb ukukhanya. Oko kuthetha ukuba usebenzisaeziilensiesXa ujonge isikrini, ngakumbi emva kobumnyama, banokunceda ukunciphisa ukuvezwa kwamaza amaza aluhlaza okwesibhakabhaka anokukugcina uvukile kwaye uncede ukunciphisa uxinzelelo ngamehlo. Nangona kunjalo, abanye abantu banokubanga ukukhanya okuluhlaza okwesibhakabhaka kwizixhobo zedijithali akubangeli iemvakalelo. Iingxaki abantu bakhalaza ngokubangelwa nje zizixhobo ezisebenzisa kakhulu izixhobo zedijithali.
