Ukufunda rhoqo phantsi komthombo wokukhanya we-stroboscopic kuya kuwonakalisa umthambo we-optic. Salayita ikhamera yefowuni ephathwayo kwaye siyikhomba kwindawo yokukhanya kwedesika. Ukuba umthombo wokukhanya uboniswe ngokucacileyo, kwangqinwa ukuba akukho nto iqhwanyazayo. Akukho ilitha = akukho monakalo wamehlo, ukuphepha i-myopia. Ukuze wenze ukukhanya okukhutshwe sisibane sokukhusela iliso kufana ngakumbi kwaye kuthambile, ngaphandle kokudakumba, samkele uyilo olungaphandle olukhuphayo.
Ukukhanya okukhutshwa ngamaso esibane kuhluzwa sisibonakalisi, isikhokelo sokukhanya kunye ne-diffuser, kwaye emva koko kukhanye emehlweni omntwana, ukuze amehlo agcinwe ekhululekile kwaye efumile ixesha elide. Umgangatho wesizwe we-AA-level illuminance = ukunciphisa ukukhathala kwamehlo. Izibane ezininzi zedesika zinomthombo owodwa wokukhanya kunye nokukhanya okuphantsi kunye noluhlu oluncinci lokukhanya. Oku kuya kwenza umahluko oqinileyo phakathi kokukhanya nobumnyama, kwaye abafundi bomntwana baya kwandiswa kwaye bancitshiswe, kwaye amehlo aya kukhawuleza adinwe.
Ukukhanya kwabiwa ngokulinganayo, kukhanyisa indawo ebanzi, kukhusela ngokufanelekileyo amehlo omntwana, kwaye kuvumela umntwana ukuba agxininise ngakumbi ekufundeni.
3000K-4000k ubushushu bombala kuthetha ukunciphisa ukukhanya okuluhlaza kunye nokuphucula ukusebenza kakuhle. Ubushushu bombala ophantsi kakhulu buya kwenza umntwana ozele, kwaye ubushushu bombala obuphezulu kakhulu buya kwandisa umxholo wokukhanya oluhlaza kwaye bonakalise iretina yomntwana.
