Le nxalenye idinga ukukhuselwa kwelanga ngakumbi, abantu abaninzi bayalibala

Xa kufika intwasahlobo nehlobo, kukho indawo enye abantu abaninzi abangayi kuyihoya, ingamehlo.

Ulusu olujikeleze amehlo luncinci, kwaye ukuvezwa rhoqo kwimitha ye-ultraviolet, ngoko kuya kukhawulezisa ukuguga kwesikhumba esijikeleze amehlo.

Ngaphezu koko, i-eyeball nayo "iyingozi" kakhulu.Ukuvezwa kwamehlo ixesha elide kwimitha ye-ultraviolet kuya kubangela ukuba i-lens iguge kwaye ibe namafu;ngokuhamba kwexesha, kuya kwandisa kakhulu ithuba le-cataract.

Oku kungenxa yokuba ukukhanya kwe-ultraviolet kukungena njengokukhanya okubonakalayo, kwaye nangona i-cornea inokucoca inxalenye enkulu yokukhanya kwe-ultraviolet, ezinye zifikelela kwi-lens kwaye zonakalise iliso.Njenge-electro-optic ophthalmia, inokuba sisiphumo somonakalo we-UV.

Ngoko akufuneki kuphela i-sunscreen, kodwa kunye nonyango lwe-VIP!Eyona ndlela ilula nesebenzayo yokukhusela amehlo akho kuku:

Ukunxiba iindondo zelanga kunokukhusela ngokwenene amehlo ethu.

Ke umbuzo ngulo, zininzi kakhulu iintlobo zeendondo zelanga kwimarike, ungazikhetha njani iindondo zelanga ezikufanelayo?Mandize kukuxhasa namhlanje.

Iiglasi zelanga ezinokukhusela elangeni kufuneka zibe nezi mpawu zimbini

Ukungaqondi kakuhle okokuqala kukuba ayizizo zonke iilensi ezikhanyayo ezibonelela ngokhuseleko elangeni.

Ukukhusela ilanga, iilensi zelanga zelanga kufuneka zicutshungulwe ngokukodwa: izinto ezikhethekileyo zetsimbi zongezwa ukufunxa imitha ye-UV, okanye iingubo ezibonisa imitha ye-UV.

Iiglasi zelanga zelanga eziqeqeshiweyo kufuneka zikwazi ukuvimba ngokufanelekileyo i-95% ukuya kwi-99% yemitha ye-ultraviolet kunye nokucoca i-75% ukuya kwi-90% yokukhanya okubonakalayo.

Isitshixo sokunxiba izibuko zelanga ezahlukeneyo ngezihlandlo ezahlukeneyo kukubona i-CAT coefficient

Umzekelo, uhlobo lwe-4 iimveliso zinefuthe elinamandla kakhulu lokukhusela ukukhanya kwaye zifaneleke ngakumbi kwimidlalo yangaphandle enokukhanya okunamandla njengamalwandle, ukutyibilika, kunye nokunyuka intaba, kodwa zimnyama kakhulu ukuba zisetyenziswe imihla ngemihla.Ngaphantsi kokukhanya okuqhelekileyo, kwanele ukukhetha udidi lwe-2 kunye neemveliso ze-3, ezinokufikelela injongo yokukhusela ilanga ngaphandle kokuchaphazela ukujonga okuqhelekileyo.

Umbala welensi awulungile njengomnyama ngokusemandleni

Nangona umbala we-lens unokubonisa ngakumbi nge-intuitively iqondo lokuhanjiswa kokukhanya (oko kukuthi, ukuhanjiswa okukhankanywe ngasentla), akusiyo mnyama ngcono, kwaye umbala ofanelekileyo kufuneka ukhethwe ngokweemfuno zokusetyenziswa.

Izibuko zelanga ezilula kakhulu ukuba zibone amehlo akho zinokhuseleko olubuthathaka lwelanga kwaye azifanelekanga ukusetyenziswa ixesha elide ngaphandle

 

Imibala emithathu yengwevu, imdaka, kunye nohlaza-grey ikhethwayo, enokufunxa okufanayo kwe-spectrum kunye nokwahlukana kombala omncinci.Inokuhlangabezana ngcono nokusetyenziswa kokukhanya kwemihla ngemihla.

Ukuba umbala umnyama kakhulu, awufanelekanga ukuwunxiba imini yonke ixesha elide.Ukukhanya kumnyama kakhulu kwaye ukhuseleko luyachaphazeleka.
