Indlela yokukhetha iiglasi zezemidlalo?

1. Iiglasi zeMidlalo zineMisebenzi eyahlukeneyo

Kukho iintlobo ezininzi zemidlalo yangaphandle, kubandakanywa ukuhamba ngebhayisikili, ukunyuka kweentaba zangaphandle, ukugijima, ukutyibilika, igalufa, inkampu, njl.

1) Iiglasi zomoyazifanelekile kubathandi bezemidlalo abazilolonga ngaphandle ixesha elide, ngakumbi kwiindawo ezinomoya ovuthuzayo nesanti.

2) Iiglasi zemidlalo yeMyopia.Ukuze uhlangabezane neemfuno zabathandi bezemidlalo be-myopia, ukuzalwa kweeglasi zezemidlalo ze-myopia kwazisa iindaba ezilungileyo kubo. Umsebenzi weeglasi zezemidlalo ze-myopia awubandakanyi kuphela ukusebenza kweeglasi ze-myopia jikelele, kodwa usebenzisa izinto ze-PC ukuxhathisa impembelelo kumphezulu, ukuze abahlobo be-myopia banokunandipha ukuzonwabisa kwezemidlalo.

3) Iiglasi zemidlalo ezipholileyo.Ukutshatyalaliswa kwexesha elide elangeni, imidlalo enzima kunye nexesha elide phantsi kwelanga, kufuneka uthenge iiglasi zezemidlalo ze-polarized.

Kwabathanda ukunyuka iintaba, ikhephu kwiintaba eziphakamileyo kulula ukulimaza amehlo. Ngokubhekiselele kwimitha ye-ultraviolet, ukukhanya okubonakalayo kwekhephu kubude beenyawo ze-10,000 kungaphezulu kwamaxesha angama-50 ngaphezu kolwandle. Iretina yeliso yonakala ngokulula, nto leyo ebangela intlungu enkulu ebizwa ngokuba bubumfama bekhephu. Iindondo zelanga zinokuwunciphisa lo monakalo, kodwa ungakhohliswa sisimo sezulu esinamafu, njengoko imitha ye-UV inokungena emafini, ukukhanya okurhabaxa kunokubangela intloko ebuhlungu, kwaye iindondo zezemidlalo zine-95-100 yokucoca.

2.Izinketho zombala kwiiglasi zezemidlalo

Jonga kwisibuko xa uthenga, ukuba unokubona ngokulula amehlo akho, kukhanye kakhulu. Ukuba ufuna ukubona umbala oyinyaniso, umbala ongcono kakhulu welensi ungwevu okanye uluhlaza; ukuba ufuna ukubona ngononophelo xa kukho amafu okanye inkungu, kungcono ukhethe i-lens ephuzi.

Iilensi ezinemibala emnyama zingcono kunezibane ezinombala okhanyayo, ezinokuthintela ngokufanelekileyo imisebe ye-ultraviolet kunye nokwandisa i-UV index. Ngokomzekelo, iilensi ezimfusa zinokunciphisa ukukhanya okubonakalayo kungena emehlweni ngaphandle kokuchaphazela ukucaca kombono. Ngoko ke, iilensi zeeglasi zokuhamba ngebhayisikili zingaba mfusa kwaye zilungele ukunxiba ixesha elide.

Iilensi ezingwevu zibonelela ngowona mbala ubalaseleyo kwaye zicetyiswa ziingcali.Iilensi ezityheli zinokuphucula umahluko kwiintsuku ezinenkungu, ngoko kuyacetyiswa ukuba ungazinxibi ngelixa uqhuba.

Umbala oqhubela phambili otyheli-luhlaza kunye neelensi zemekyuri ezimfusa zegolide zinokuhluza ukukhanya okubhlowukunye nokwandisa umahluko phakathi kwesibhakabhaka kunye nomhlaba, ngoko ke iiglasi zegalufa zisebenzisa iilensi ezityheli-luhlaza kunye nemfusa ukwenza i-sphere yahluke ngakumbi kwibala lombono.

Yonke imihla, ilanga lihlala likhupha iindidi ezintathu zamaza okukhanya: ukukhanya kwe-ultraviolet, ukukhanya okubonakalayo kunye nokukhanya kwe-infrared. Ukuba akukho khuselo olufanelekileyo lweglasi, ngamnye wabo uya kubangela umonakalo omkhulu kunye nefuthe emehlweni. Kuyabonakala ukuba umbala ubaluleke kakhulu ukukhetha iperi yeglasi ehambelana neemfuno zakho zemidlalo. Ukongeza, kungcono ukuthenga iiglasi ezichasene ne-radiation ezinokumelana ne-UVA kunye ne-UVB.

3.Sports iiglasi Ukukhetha imilo

Khumbula umgaqo wokuhambelana - ubume befomula yobuso obujikelezileyo, ubuso besikwere khetha iellipse. Ngokukodwa: Ubuso besikwere: Iiglasi ezibanzi zesitayile se-aviator zinokuthambisa umhlathi obalaseleyo.

Ubuso obungqukuva:Ilungele iiglasi ezinezakhelo ezingqindilili kancinci, iilensi ezipholileyo, kunye nemibala emnyama, enembonakalo yokucutheka kobuso.

Ubuso obude:Kufuneka ukhethe iilensi ezigobileyo okanye ezigobileyo, ezinomlinganiselo obhityileyo, onika abantu imvakalelo yolungelelwaniso ngokubonakalayo. Iifreyimu zamehlo ekati lolona khetho lungcono.

Ubuso obumbhoxo:zilungele izibuko zelanga zeemilo ezahlukeneyo, kukho ukhetho oluninzi lokukwenza wonwabe.

Ubuso obuncinci:ifanelekile ukunxiba isakhelo esincinci okanye iiglasi ezingenasiphako, ukukhetha iilensi ezintle kuya kuba neziphumo ezingalindelekanga.

Ukukhethwa kwesakhelo kufuna ukuthamba, ukuqina, ukuchasana kwempembelelo, kunye nokukhuselwa okukhuselekileyo kobuso kumonakalo ngexesha lokuzilolonga. Uyilo lwe-veneer yesakhelo lunokugcina amehlo esondele kumda wesakhelo ukukhusela umoya onamandla ukuba ungabonakali emehlweni ngexesha lezemidlalo ezikhawulezayo.

Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
