Unyango lwe-UV phototherapylunyango lokukhanya kwe-ultraviolet oluyi-311 ~ 313nm. Ikwaziwa njengonyango lwemitha ye-ultraviolet eqingqiweyo (Unyango lwe-NB UVB).Icandelo elincinci le-UVB: ubude be-311 ~ 313nm bunokufikelela kumaleko we-epidermal yesikhumba okanye kwindawo edibana kuyo i-epidermis yokwenyani, kwaye ubunzulu bokungena abunzulu, kodwa busebenza kwiiseli ekujoliswe kuzo ezifana nee-melanocytes, kwaye bunefuthe lonyango.
Uvavanyo lwezonyango lubonise ukuba uluhlu lwamaza angama-311-312 nm olukhutshwa yi-311 narrow spectrum UVB luthathwa njengolona kukhanya lukhuselekileyo nolusebenzayo. Lunezibonelelo zokusebenza kakuhle kunye nemiphumo emibi emincinci kwi-psoriasis, i-vitiligo kunye nezinye izifo zesikhumba ezingapheliyo.
Nangona kunjalo, kungcono ukulandela icebiso okanye imiyalelo kagqirha xa usebenzisa isixhobo sonyango lwe-ultraviolet, kuba ukusetyenziswa kakhulu kwesixhobo sonyango lwe-ultraviolet kuya kubonakala ukutsha okuncinci, okubonakala njengolusu olubomvu, ukutsha, ukuxobuka kunye nezinye iimpawu zokutsha okuncinci.
Okwesibini, imisebe ye-ultraviolet iya konakalisa i-retina nge-cornea, nto leyo ebangela umonakalo kwiiseli ze-retina, ngoko ke abantu okanye izilwanyana ezichatshazelwe yimisebe ye-ultraviolet ixesha elide kufuneka zinxibe iimpahla zokuzikhusela kunye nezinye izixhobo, zinxibe iiglasi zelanga zokuzikhusela.
