Ukukhanya ukuphela komthombo wokukhanya otholakala endlini ebusuku.Ekusetshenzisweni kwansuku zonke kwasendlini, umthelela wemithombo yokukhanya ye-stroboscopic kubantu, ikakhulukazi asebekhulile, izingane, njll.Kungakhathaliseki ukuthi ufunda esifundweni, ufunda, noma uphumule ekamelweni, imithombo yokukhanya engalungile ayigcini nje ukunciphisa ukusebenza kahle, kodwa ukusetshenziswa kwesikhathi eside kungase kushiye ingozi efihliwe empilweni.

U-Lightman wethula abathengi ngendlela elula yokuqinisekisa ikhwalithi yeIzibani ze-LED，Sebenzisa ikhamera yefoni ukuze uqondanise umthombo wokukhanya.Uma isitholi sokubuka sinemizila eguquguqukayo, isibani sinenkinga "ye-strobe".Kuyaqondwa ukuthi lesi sigameko se-stroboscopic, okunzima ukusihlukanisa ngeso lenyama, sithinta ngqo impilo yomzimba womuntu.Lapho amehlo evezwa endaweni ye-stroboscopic ebangelwa izibani eziphansi isikhathi eside, kulula ukubangela ubuhlungu bekhanda nokukhathala kwamehlo.

Umthombo wokukhanya we-stroboscopic empeleni ubhekisela ekuvamiseni nasekuhlukeni kwezikhathi ezithile kokukhanya okukhishwa umthombo wokukhanya ngokukhanya okuhlukile nombala ngokuhamba kwesikhathi.Umgomo wokuhlola ukuthi isikhathi sokuvala sefoni ephathekayo sishesha ukwedlula ukuphazima okuguquguqukayo okungama-24/isekhondi okungabonwa ngeso lomuntu, ukuze into ye-stroboscopic engabonakali ngeso lenyama iqoqwe.

I-Strobe inemiphumela ehlukene empilweni.I-American Epilepsy Work Foundation iveze ukuthi izici ezithinta ukwethulwa kwesithuthwane se-photosensitivity ikakhulukazi zifaka imvamisa ye-scintillation, amandla okukhanya, kanye nokujula kokuguquguquka.Ocwaningweni lwethiyori ye-epithelial ye-photosensitive isithuthwane, uFisher et al.waveza ukuthi iziguli ezinesifo sokuwa zinamathuba angu-2% kuya ku-14% okuqalisa ukuquleka ngaphansi kokukhuthazwa kwemithombo yokukhanya ye-scintillation.I-American Headache Society ithi abantu abaningi abanekhanda elibuhlungu bazwela kakhulu ekukhanyeni, ikakhulukazi i-glare, imithombo yokukhanya ekhanyayo ene-flicker ingabangela i-migraine, futhi i-low frequency flicker inzima kakhulu kune-high frequency flicker.Ngenkathi becwaninga umphumela wokucwayiza ekukhathaleni kwabantu, ochwepheshe bathola ukuthi ukucwayiza okungabonakali kungaphazamisa umzila wenhlamvu yeso, kuthinte ukufunda futhi kuholele ekwehleni kwamehlo.
