Uma kuziwa emisebeni ye-ultraviolet, wonke umuntu ucabanga ngokushesha ngokuvikelwa kwelanga esikhumbeni, kodwa uyazi ukuthi amehlo akho nawo adinga ukuvikelwa kwelanga?
Iyini i-UVA/UVB/UVC?
Imisebe ye-Ultraviolet (UVA/UVB/UVC)
I-Ultraviolet (UV) ukukhanya okungabonakali okunobude obufushane beza namandla aphezulu, okungesinye sezizathu zokuthi kungani ukukhanya kwe-ultraviolet kuyingozi empilweni. Ngokwamaza ahlukene emisebe ye-ultraviolet, imisebe ye-ultraviolet ihlukaniswe yaba izigaba ezintathu: UVA/UVB/UVC. Iningi lemisebe ye-ultraviolet esichayeka kuyo i-UVA kanye nenani elincane le-UVB. Iso lingesinye sezicubu ezizwela kakhulu emzimbeni wethu. Amaza e-UVA aseduze nokukhanya okubonakalayo futhi angadlula kalula ku-cornea futhi afinyelele kulens. Amandla e-UVB angaphansi kancane kune-UVC, kodwa ngemithamo ephansi, asengadala umonakalo.
Ingozi emehlweni
Njengamanje, indawo ezungezile yemvelo isaqhubeka impofu, futhi “imbobo” yongqimba lwe-ozone emkhathini iya ngokuya iba mkhulu. Abantu bachayeka emazingeni aphezulu emisebe ye-ultraviolet eyingozi kunangaphambili, futhi amandla emisebe ye-ultraviolet amuncwa izicubu zamehlo nawo ayanda kancane kancane. Ukumunca kakhulu imisebe ye-ultraviolet kwandisa ingozi yezifo zamehlo ezifana ne-photokeratitis, i-pterygoid kanye nokuqhekeka kobuso, ulwelwesi, nokonakala kwe-macular.
☀Ngakho-ke, kufanele ukhethe kanjani izibuko zelanga?☀
1. Abantu abane-myopia kufanele banake ukuthi akukho yini ukungakhululeki okufana nesiyezi uma beyizama. Kunconywa ukuthi uye esibhedlela samehlo sochwepheshe ukuze uthole i-optometry nezibuko ukuze ukhethe amalensi afaneleka kakhulu kuwe.
2. Lapho uthenga izibuko zelanga, qiniseka ukuthi ufunda ilebula noma uthole ukuthi izibuko zelanga zingakwazi yini ukuvimba u-99% -100% we-UVA ne-UVB.
3. Izibuko ezinemibala ≠ izibuko. Abantu abaningi bacabanga ukuthi inqobo nje uma izibuko zinemibala futhi zingavimba ilanga, ziyizibuko. Ipheya elihle lezibuko zelanga kufanele likwazi ukuvimba kokubili ukukhanya okunamandla nemisebe ye-ultraviolet. Umsebenzi oyinhloko wombala we-lens ukuvimba ukukhanya okuqinile ukuze abantu babone izinto ngaphandle kokuxhopha, kodwa ayikwazi ukuvimba imisebe ye-ultraviolet.
4. Amalensi agqamile anganciphisa ukubenyezela okuvela ezindaweni ezinjengamanzi noma indawo egandayiwe, angenza imisebenzi yokushayela noma yamanzi iphephe noma ijabulise kakhudlwana, kodwa ayivikeli emisebeni ye-UV! Amalensi agqamile kuphela alashwe ngesivikelo se-UV angavikela emisebeni ye-UV. Udinga ukuqonda ngokucacile ngaphambi kokuthenga.
5. Akungcono uma umbala welensi umnyama futhi uvikela kakhulu! Ayivimbi ngempela imisebe ye-UV eyengeziwe!
6. Ifomu lezibuko zelanga alikhawulelwe kuhlobo lwefreyimu. Uma usunazo izibuko ze-myopia, ungakhetha izibuko zelanga zokunamathisela!
Ukuvikelwa kwelanga kwansuku zonke kwamehlo kubaluleke kakhulu. Wonke umuntu kufanele athuthukise ukuqwashisa kwakhe ngokuvikela iso elangeni futhi athuthukise imikhuba emihle yokuvikela ngaphandle.
Uma ufuna ukwazi okwengeziwe mayelana nezitayela zemfashini yezibuko kanye nokubonisana nezimboni, sicela uvakashele iwebhusayithi yethu futhi usithinte noma nini.
