Qonda ukubaluleka kweiindondo zelangakukhathalelo lombono

Iindondo zelangazingaphezulu nje kwefashoni okanye isincedisi-simbo somntu;zisisixhobo esibalulekileyo ekukhuseleni amehlo ethu kwimiphumo eyingozi yelanga elibukhali.Inkqubela phambili kwinkcubeko yethu yezinto eziphathekayo iye yenzaiindondo zelangaukhetho oludumileyo lokuphucula ubuhle kunye nokubonakalisa isimbo somntu.Nangona kunjalo, umsebenzi ophambili weiindondo zelangakukukhusela amehlo ethu axabisekileyo kumonakalo ongabonakaliyo obangelwa yimitha yeultraviolet (UV).Iingcali zamehlo zigxininisa imfuneko yokusetyenziswa rhoqoiindondo zelangaukugcina umbono osempilweni, njengoko amehlo echaphazeleka kakhulu kukufunxa le mitha iyingozi.Kubalulekile ukuqaphela ukuba umonakalo owenziwe yimitha ye-UV uyanda kwaye awunakuguqulwa, ukwenzaiindondo zelangakufuneka ube nayo kumntu wonke.

Umonakalo owongezelekayo nongenakulungiseka kwimitha ye-UV

Ngokungafani nokukhanya okubonakalayo, ukukhanya kwe-ultraviolet akukwazi ukubonwa ngeso lenyama.Ngoko ke, umntu akanakulinganisa ubungakanani bomonakalo owenziweyo de kube kusemva kwexesha.Yiyo loo nto kubalulekile ukunxibaiindondo zelangangamaxesha onke.Kukho iimpawu ezimbini eziyingozi zemitha ye-UV efuna ingqalelo yethu.Okokuqala, umonakalo ovela kwimitha ye-UV uqokelela ngokuhamba kwexesha.Ukuba sesichengeni ixesha elide kule ndawo kunokwenza amehlo atyekele kuluhlu lwezifo zamehlo, eziquka ukonakaliswa kwe-cornea kunye ne-retinal, ukugquma kwelens, kunye norhatyazo.Ukuqokelelana komonakalo wamehlo onxulumene ne-UV nako kuchaphazela ngqo umbono womntu, okwenza kube nzima ngakumbi ukubuyisela umbono oqhelekileyo.Okwesibini, umonakalo owenziwe yile mitha awunakuguqulwa, nto leyo ethetha ukuba xa kusenzeka iingxaki ezinxulumene nombono, azinakulungiswa ngokupheleleyo.Utyando lwe-cataract, umzekelo, luhlala lubandakanya ukutshintshwa kwe-lens ye-intraocular, kodwa ayilungisi umonakalo ovela kwixesha elide le-UV.

iingenelo kunye neempawu zelanga njengemveliso yokukhusela amehlo

Inzuzo yeendondo zelanga kukuba zinokuvala ngokufanelekileyo kwaye zihluze imitha ye-ultraviolet eyingozi ekufikeni kwamehlo ethu.Iindondo zelanga ezikumgangatho ophezulu, ezinje ngeNgqokelela yethu eCokisiweyo, zibonelela ngokhuseleko oluphezulu ngetekhnoloji yelensi ephucukileyo.Ngokusebenzisa iilensi ezikhethekileyo, ezi zibuko zelanga zivala ukuya kuthi ga kwi-100% yemitha ye-UV eyingozi, iqinisekisa ukhathalelo olupheleleyo lwamehlo.Ukongeza, iiglasi zethu zelanga zibonelela ngezinto ezongezelelekileyo njengokukhanya kwepolarized.Eli nqaku linciphisa ilitha ukusuka kwindawo ekhanyayo efana namanzi okanye izinto ezikhanyayo, ukunika ukucaca kunye nentuthuzelo kumbono wakho.Ngokukhetha iiglasi zelanga ezipholileyo, awuphuculi impilo yamehlo akho kuphela, kodwa namava akho onke okubonwayo.
