Unokukhetha njani iilazi zelanga ngeendlela zokukhusela?

Iqondo lokutshatyalaliswa kwelanga kunye nenqanaba lokukhusela kwimilayezo ye-ultraviolet zibonakaliso ezimbini ezibalulekileyo eziqinisekisa umgangatho kunye nobubanzi bemodeli yelanga. Ngoko, makhe sijonge indlela yokukhetha ama-sunlight ngeendlela zokukhusela.

Umgangatho wokukhusela izibuko zelanga

Kuphelele kukho amanqanaba amane okukhusela ama-glass. Inqanaba "0" lithetha ukuba kulezi glasi unokuhamba kuphela kwiimozulu zezulu okanye ezinamafu, njengoko zidlula ukusuka kuma-80% ukuya kwi-100% yemisebe yelanga. "1" ilungele ilanga elibuthathaka, umzekelo, ukuhlwa kwehlobo. Iqondo lokutshatyalaliswa kwemitha ngamalensi enokumakisha amanqaku angama-43 ukuya kuma-80%. Amaphupha agqitywe "2" afanelekileyo ilanga elinamandla, anokukhethwa ukuba unqwenela ukuchitha ihlobo eluzini. Zihlala zihlala zikhanya kwelanga, zidlula kwi-18% ukuya kwi-43% yemitha. "3" ifanelekile ukuphumla elwandle, apho ilanga sele likhulu kakhulu. Ipesenteji yokudluliselwa kuzo kuphela 8-18% kuphela. Iingongoma ezikhuselekileyo zinqanaba "4". Ngelo lensi, amehlo akho aya kukhululeka nakwi- ski resort , njengoko badlula kwi-3% ukuya kwi-8% yeemitha zelanga.

Ulwazi malunga naluphi ukukhusela okumele lube ngamaziko okukhanya, kubalulekile ukujonga iilebula, equlethe idatha kumenzi. Ezi ileta kufuneka zibe yinto nayiphi na imodeli esemgangathweni. Ukongezelela, kuyafaneleka ukuthobela ingqalelo ukuba inqanaba elikhuselekileyo lokukhusela, i-darker lens. Ngoko, iiglasi kunye nenqanaba lokukhusela "4" alinakusetyenziswa xa ushayela imoto, yinto emnyama.

Iimvani zeeklasi kunye nokukhuselwa kwe-UV

Indlela yokumisela izinga lokukhuselwa kwamagumbi okukhanya kwamabhinqa, ngaphezu kwenkcazelo yokudluliselwa kokukhanya? Ngenxa yale njongo, kukho enye ipharamitha kwileyibhile - idatha malunga nokuba yiyiphi imitha ye-UV (i-UVA kunye ne-UVB spectra). Kukho iintlobo ezintathu zeengongoma kuxhomekeke kule parameter:

1. Iziqhenkco - ezi glasi azikhangeli umbane onobungozi (ukudluliselwa kwe-80-100%), oko kuthetha ukuba unxiba ukususela apho ilanga lingasebenzi.
2. Jikelele- iilazi ezinokumakisha zilungele ukusetyenziswa kwesi sixeko, kuba iiglasi zazo zibonisa ukuya kwi-70% ye-radiation yezimbonakalo zombini.
3. Ekugqibeleni, ukuzonwabisa olwandle okanye ezintabeni, kufuneka ukhethe iziglasi eziphawulwe ukhuseleko oluphezulu lwe-UV , njengoko zigcina zigcina zonke iimitha eziyingozi, eziphindaphinda ngokuphindaphindiweyo xa ziboniswa ngamanzi.
