Iimvani zeeklasi kunye ne-diopters

Ehlotyeni, abantu abaninzi abanamahlwempu bafanele bagqoke iilensi zokudibanisa ukukhusela amehlo abo ekukhanyeni kwe-UV. Izibuko zelanga kunye ne-diopters yisisombululo esihle kakhulu kule ngxaki, kuba ikuvumela ukuba ubone kakuhle kwaye ungabandezeleka ngokukhanya okukhazimulayo ngexesha elifanayo.

Unokukhetha njani iilazi zokukhanya ezilungiselelwe ngokulungelelanisa nge-diopters?

Okokuqala, kufuneka uqhagamshelane ne-ophthalmologist ukufumana iilensi ezifanelekileyo. Ugqirha uya kucebisa uhlobo, umbala kunye neqondo lokumnyama.

Ngokubhekiselele kwimilo yesakhelo, umthunzi weglasi kunye nesitayela, unokuthembela kwintetho yakho. Iingongoma ezibaluleke kakhulu ukujonga ngazo zi:

1. Izinto ezivela kuyo iilensi. Iiplastiki, kunye nomgangatho ophakamileyo, uphula ngokukhawuleza kunye nemiqwenga, iphosakele kalula. Ikhethelo elikhethekileyo liya kuba iglasi.
2. Uluhlu lo khuselo. Kubalulekile ukujonga ukuba ukutshiza iilensi kuvimbela ukungena kwemisebe ye-ultraviolet, kwakunye nokukwazi ukulingana nesantya sokukhusela.
3. Tshintsha ukukhanya. Igalagi yekhwalithi yangempela ayichaphazeli ukuguqulelwa kombala kwaye ayikuguqisi umthunzi, kuphela ukukhanya kokungena kwi-retina.

Iidanga zelanga ezithandwayo kakhulu kwiiglasi kunye ne-diopta ebizwa ngokuthi "i-chameleon" - ukhetho oluhle kakhulu, xa udla ngokukhanya. I-sensitive sensitive photocromic layer ishicilela i-glass of sun in bright sun and returns to the state of the room. Kodwa ku funeka kuqatshelwe ukuba ukuchithwa ngokukhawuleza kokulahlekelwa iipropati zayo kunye nama-lens kuya kuguqulwa kaninzi.

Iimvani zeeklasi kunye ne-diopters kubaqhubi

Olu hlobo lwezesebenzi kufuneka lube neengubo ezichasayo ezichasayo, ezingabonakali nje nge-ultraviolet kuphela, kodwa nezibonakaliso ze-asphalt ezimanzi, ukukhanya kwezibane zesitalato kunye neengqamlezo zezimoto ezizayo. Ngaphezu koko, umqhubi kufuneka abone ideshibhodi, ngoko iiglasi kufuneka zithengwe nge-gradient spraying.

Ukuvavanya i-accessory, ungaqhuba uvavanyo lwakho:

1. Beka phambi kweglasi ezifanayo.
2. Jonga kubo ngokusebenzisa imodeli oyikhethayo.
3. Ukuba ujikeleza i-degrees ezingama-90, iilensi zamagalasi afanayo zibonakala zibe mnyama, ngoko zineenkcukacha zokukhawuleza.

Izibuko zemibala yezemidlalo kunye ne-diopters

Xa ukhetha olu hlobo lofikelelo, kufuneka uqwalasele ezi zilandelayo:

• ulungelelwano oluqinileyo lomgca ukuya kwiglasi;
• izibambo ezinobumba;
• bunzima;
• umgca wendlela;
• ubukho be-sealant;
• Umgangatho ophezulu wokukhusela kwimisebe ye-ultraviolet.

Iipropati ezidwelisweyo ziyimfuneko ukwenzela ukuba ngexesha lezemidlalo iiglasi aziwa, zibambe kakuhle ebusweni, zingaphazamisi ukuhamba, imisebe yelanga ihlanjululwe ngokubanzi, inokukhuselwa kwintloko yomoya.

Iiglasi zelanga eziglasi kunye ne-diopters

Iimodeli ezinikezelwe zixhotyiswe ngamacwecwe - ezimbini iilensi ezingaphakanyiswa (mhlawumbi zisuswe) okanye zinciphwe. Ukukhuselwa kwelanga Izixhobo zolu hlobo zilungelekile kuba zibini eziglasi eziqhelekileyo ezineglasi ezibonakalayo, kunye neepaliti eziphathekayo ezithintela ukungena kwe-UV.

Ukuthenga iziglasi ngokugqithisa kubalulekile ukuqwalasela ngokucophelela indlela yokubamba. Iilensi kufuneka zinyuka ngokukhawuleza kwaye ziwe, ngaphandle koxinzelelo, zingawa, kwaye zilungise ngokufanelekileyo isimo esifanelekileyo.

Ukongezelela, kubalulekile ukufanisa ngokuchanekileyo ukuma kunye nobukhulu beiglasi, ukulungelelana kwazo ngokufanayo. Isakhelo esifanelekileyo sifanele sibe sesinye iilensi zamnyama kunye ne-dioptric, ngokukhethekileyo zetsimbi.
