Imitha ye-ultraviolet inempembelelo eluswini lomntu, amehlo kunye nenkqubo ye-nervous central.Ngaphantsi kwesenzo esinamandla semitha ye-ultraviolet, i-photodermatitis ingenzeka;Iimeko ezimandundu zisenokubangela umhlaza wolusu.Xa evezwe kwimitha ye-ultraviolet, iqondo lokulimala kwamehlo lilingana nexesha, ngokuphambeneyo ngokulinganayo kwisikwere somgama osuka kumthombo, kwaye unxulumene ne-engile yokukhanya kokukhanya.Imitha ye-Ultraviolet isebenza kwinkqubo ye-nervous central kwaye inokubangela intloko ebuhlungu, isiyezi, kunye nobushushu bomzimba obuphezulu.Ukusebenza emehlweni, kunokubangela i-conjunctivitis kunye ne-keratitis, eyaziwa ngokuba yi-photogenic ophthalmia, kwaye inokubangela ukuba kubekho urhatyazo.Indlela yokuthatha amanyathelo okukhusela xa usebenza kwigumbi lovavanyo lokuguga le-UV.

1. Izibane ezinde ze-ultraviolet ezinobude obungamaza e-UV obuyi-320-400nm zinokusetyenzwa ngokunxiba impahla yokusebenza engqindilili kancinane, iiglasi zokhuselo ze-UV ezinomsebenzi wokuphucula i-fluorescence, kunye neeglavu ezikhuselayo zokuqinisekisa ukuba ulusu kunye namehlo akavezwanga kwimitha ye-UV.

2. Ukutshatyalaliswa kwexesha elide kwisibane se-ultraviolet ephakathi kunye ne-wavelength ye-280 ~ 320nm kunokubangela ukuphuka kwee-capillaries kunye nobomvu kwesikhumba somntu.Ke xa usebenza phantsi kokukhanya okuphakathi kwe-ultraviolet, nceda uqiniseke ukuba unxibe iimpahla ezikhuselayo kunye neeglasi ezikhuselayo.

3. Ubude be-Ultraviolet wavelength 200-280nm isibane esifutshane se-ultraviolet, igumbi lokuvavanya ukuguga kwe-UV, i-wave wave ultraviolet iyonakalisa kakhulu kwaye inokubola ngokuthe ngqo i-nucleic acid yezilwanyana kunye neebhaktheriya, ibangela i-cell necrosis, ngaloo ndlela ifezekisa umphumo we-bactericidal.Xa usebenza phantsi kwemitha ye-ultraviolet ye-shortwave, kuyimfuneko ukunxiba imaski ekhuselayo ye-ultraviolet ukukhusela ngokucokisekileyo ubuso kunye nokuphepha umonakalo ebusweni namehlo obangelwa yimitha ye-ultraviolet.

Qaphela: Iiglasi ezikhuselayo ze-UV kunye nemaski zinokudibana neemilo zobuso ezahlukeneyo, ngokukhuselwa kwamashiya kunye nokhuseleko lwamaphiko ecala, olunokuthi luthintele ngokupheleleyo imitha ye-UV ukusuka kumacala ahlukeneyo kwaye ikhusele ngokufanelekileyo ubuso kunye namehlo omqhubi.
