Ngokuqhelekileyo, xa ukhwele kwingqatsini yelanga, kulula ukonakalisa amehlo ngenxa yokukhanya okubonakaliswa yindlela okanye imitha ye-ultraviolet eyomeleleyo ngokugqithisileyo, ebangela ukuphuka kwesikhumba se-punctate, ukuvutha, kunye nentlungu kwi-cornea, ebangela iinyembezi, imizimba yangaphandle, ukutshisa, kunye noxinzelelo lwamehlo. Iimpawu ezifana neentlungu kunye nokungakwazi ukuvula amehlo.
Ukuba kukho ukungabikho kwamanyathelo okukhusela afanelekileyo, kulula kakhulu ukubangela izifo zamehlo, ngakumbi xa ukukhwela umgama omde kunomoya, kwaye kunokubakho nemiphumo emibi ebangelwa zizinambuzane ezindizayo okanye izinto zangaphandle ezibhabhayo emehlweni. Ukongeza kwiinambuzane ezincinci ezindizayo okanye izinto zangaphandle ezindizayo emehlweni ngexesha lokuhamba ngebhayisikili, ukukhanya kwelanga okunamandla kunye nemitha ye-ultraviolet enamandla ehlobo kunokubangela umonakalo emehlweni ethu.
Ukuba ufuna ukukhusela amehlo ethu. Ukukhetha iiglasi ezifanelekileyo zokukhwela ibhayisekile kuyimfuneko. Okulandelayo, makhe sijonge indlela yokukhusela amehlo ethu xa sikhwela ehlotyeni.
Kutheni Unxiba iiglasi zeBhayisekile?
1. Ingangeni moya, ingangenwa luthuli kunye nesanti
Kuba xa ukhwela endleleni, isantya sesithuthi siya kuba ngaphezu kwe-30km/h, okanye nangaphezu kwe-50km/h. Ukuba amehlo abonakaliswe ngeli xesha, kuya kuba yingozi enkulu emehlweni; xa udibana nendlela enomoya omninzi nesanti, amehlo akho afumana isanti ngokulula. Ukuba uhamba ngaphandle kweeglasi ixesha elide, kunokwenzeka ukuba kubangele i-trachoma, kwaye amehlo akho aya kuba negazi kwaye abomvu. Ngoko ke, xa ugibela, kufuneka unxibe iiglasi ezingenamoya ezihambelana nesimo sobuso ukuze usebenze.
2. Vimba ukukhanya okunamandla kunye nemitha ye-ultraviolet
Imozulu ehlotyeni ishushu nje kwaye inesiyezi, kwaye ilanga elingaboniyo liya kwenza abantu bangafuni ukuvula amehlo abo. Wonke umntu umele ukuba wayekhe wayiva le mvakalelo. Ukuba oku kwenzeka ixesha elide, amehlo aya kubandezeleka ngenxa ye-cataract. Eyona ndlela isebenzayo yokuphepha ukulimala kokukhanya okunamandla emehlweni kukugqoka iiglasi kwaye ungakhangeli ngokuthe ngqo ekukhanyeni okunamandla.
3. Thintela ukudinwa okubonakalayo
Sinxiba iindondo zelanga ngenxa yokuba imitha yelanga yomelele kakhulu, kodwa izibuko zelanga eziqhelekileyo zithintela ukukhanya yaye zinciphisa nokukhanya okusingqongileyo, nto leyo eyandisa umthwalo emehlweni ukusa kumlinganiselo othile, iwenza amehlo abe buhlungu ngokugqithiseleyo yaye ibangela ukudinwa okubonakalayo. Ezinye iiglasi ezinempembelelo ye-polarizing zinokwenza le ntsilelo kakuhle kakhulu, ziphucule isisombululo sezakhiwo ezijikelezileyo ngelixa zithintela ukukhanya, kwaye zinciphise umthwalo obonakalayo emehlweni.
Indlela yokukhetha iiglasi zokuhamba ngebhayisikile?
Kuba iindondo zokukhwela ibhayisekile zibaluleke kakhulu, kufuneka sikhethe iiglasi ezigcweleyo nezifanelekileyo. Ziziphi iinkalo esifanele siziqwalasele?
★Amandla esakhiwo
Xa sikhwela ngokukhawuleza, ngamanye amaxesha izinto zasemzini ezifana namatye okanye izinambuzane ezibhabha ngaphambili zinokubetha iindondo. Amandla eeglasi ozinxibayo abaluleke kakhulu. Ukuba amandla awanele, kunokubangela umonakalo kwiiglasi. Umonakalo kwiiglasi kunokwenzeka ukuba wenze umonakalo ongenakulungiseka. Ngokomzekelo, ukuba i-cornea (i-transparent layer ngaphandle kwe-eyeball emnyama) yonakele, ayikwazi ukubuyiselwa ngokupheleleyo kwaye iya kushiya izibazi. Ngoko ke kubaluleke kakhulu ukukhetha iperi yeglasi elungileyo.
★Ukhuseleko
Ukukhwela ibhayisekile ngumdlalo wangaphandle. Ukukhanya kwelanga kunye nomoya kwindalo kuya kuvela kuwo onke amacala. Ukuba ukugquma kweeglasi akufanelekile ngokwaneleyo, kuya kubakho iindawo ezifileyo, ezingayi kukwazi ukukhusela kakuhle amehlo. Ngoko ke, xa ukhetha iiglasi, kungcono ukuba uzame ngokwakho ukuze ufumane ukugubungela zonke iiglasi ngaphambi kokuthenga.
★Ukuphefumla
Xa uhamba ngebhayisikili ehlotyeni elishushu, ngakumbi emva kwemvula, umphunga wamanzi uya kubambelela kwi-lens kwiiglasi, ngoko xa ukhetha iiglasi zokuhamba ngebhayisikile, ukusebenza kwe-lens ye-anti-fog kuyinkalo efuna ukuqwalaselwa ngumntu wonke. Ukuba ubushushu obungaphakathi kwiiglasi buyaphela, buya kuvelisa inkungu, nayo engamkelekanga.
★Ukuqina
Xa sikhwela ngokukhawuleza, ukuzinza kokugqoka iiglasi nako kufuneka kuqwalaselwe. Xa ukhwele ngokukhawuleza, ukuba iiglasi zihlala ziwela, kufuneka uhlale ubambe isakhelo ngezandla zakho, eziyingozi kakhulu. Mhlawumbi iifreyimu zakho zikhulu kakhulu kwaye azihlali ngokukhuselekileyo kwibhulorho yempumlo yakho, nezona glasi zibalaseleyo azinamsebenzi.
★Ipolarization
I-polarization kukukwazi kweeglasi ukucoca amaza okukhanya amdaka avela kukukhanya kwelanga kwizinto ezibethayo emva koko zibonakalise. Inokuhluza ukukhanya okuninzi okupholalisiwe kwimbonakalo esasazekileyo, ngokwenjenjalo inciphisa ubunzulu bokukhanya esibhakabhakeni. Kulo msebenzi, kukho ezinye iingcali, kwaye abantu abaninzi baya kubhidanisa nombala welensi. Ezi zimbini zineentsingiselo ezahlukeneyo.
Umbala weLens.
Imibala eyahlukileyo yeelensi zeeglasi zokuhamba ngebhayisikili iya kuba nemiphumo eyahlukileyo. Kufuneka sikhethe iilensi zemibala eyahlukeneyo kwindawo ethile. Ukuba mnyama umbala welensi, kokukhona ukukhanya kumnyama. Ukugqoka imibala eyahlukeneyo yeelensi kwiindawo ezahlukeneyo kunokunyusa ukuchasana kokukhanya kunye nokwenza izinto esizibonayo zicace ngakumbi. Ngaphandle koko, ukukhetha umbala ongalunganga kuya kuba yinto echaseneyo kwaye kubangele ingxolo engadingekile. umonakalo.
Amehlo yifestile emphefumlweni, kwaye kubaluleke kakhulu ukukhusela amehlo akho. Kufuneka uqale kwiinkcukacha ezininzi ukukhusela amehlo akho xa uqhuba ibhayisekile. Khumbula ukunxiba iperi yeendondo zebhayisekile ezikulingana nawe.
Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
