Ngandlela-thile, ngisho nasesimo sezulu esibhakabhakeni, ama-ray angu-80% we-ray ultraviolet ayingozi kithi, futhi ngisho nasesimweni sezulu asikwazi ukwenza ngaphandle kokuvikelwa okwengeziwe. Ngakho-ke, odokotela bancoma ukuthi wonke umuntu ngaphandle kokusebenzisa izibuko kanye ne-sunscreen. Funda ukuthi ungakhetha kanjani izibuko zokukhanya ezilungile futhi uzothola ukuthenga kwakho kwehlobo elizungezile!
Futhi nasi iseluleko esiyinhloko - kungcono ukuthi ungabi yizinyosi, ngakho-ke akudingeki ukuba uphinde uzisole: o, i-mail chain yayifushane. Ukuthenga izibuko ezishibhile ezingxenyeni ezingaqinisekisiwe, ezivela kumkhiqizi ongaziwa, ubulimaza ngokwengeziwe amehlo akho. Iqiniso liwukuthi nje izibuko ezimnyama azivimbeli ukungena kwemisebe eyingozi. Kodwa nge-dimming, umfundi wethu uyazikhukhumeza, asigcini, futhi kuvela ukuthi iso lithola ngisho nakakhulu kakhulu i-ultraviolet!
Umphumela ukuwohloka kombono, i-cloudiness ye-crystal, ukushisa kwe-retinal. Isifo esivame kakhulu esibangelwa imisebe eyingozi kuyisithombe photoatatitis (umonakalo we-corneal). Njengokushisa kwelanga, ukuzwa kungaba buhlungu kakhulu. Ukuvuthwa, ukubomvu kanye nomzwa wesihlabathi emehlweni, izinkophezelo ezikhukhumele, ngisho nokulahlekelwa yesikhashana kwombono - lezi zonke izimpawu ze-photokeratitis. Ifomu layo elibi kakhulu liwukuthi "ukuphuphutheka kweqhwa", okuthinta abagibeli nabagibeli. Kulokhu, ukubuyiselwa kombono kuzothatha izinsuku eziningana, futhi ukukhala nokucasuka kwamehlo kungaphila kuze kube phakade.
Zonke lezi zinkathazo zikhuluma ngokuthenga "okulungile", hhayi izigcawu ezimbi. Kulesi simo, kungcono ukuxhumana nesitolo esikhethekile se-optics. Ngempela, lapha zonke izimpahla ziqinisekisiwe. Futhi akudingekile ukukhetha izinhlobo zezimoto ezibiza kakhulu. Ungathenga izibuko ezivela kubakhiqizi abadumile kangaka, ngamanani endaweni ethile kusuka kuma-dollar angu-200 kuya ku-300, kodwa okuyiwona ovikela kakade imisebe ye-ultraviolet.
I-Glass noma i-plastic?
Lo mbuzo uphendulwe yibo abakhiqizi bomhlaba abahamba phambili isikhathi eside: namuhla izinhlobo eziningi zezibuko zikhiqizwa kusuka epulasitiki. Nakuba ezweni lethu kusengenzeka ukuzwa lokho, kuthi, kungcono ukuvikela amalensi amaminerali (okungukuthi, ingilazi) kusukela elangeni. Okokuqala, akunjalo. Okwesibili, ipulasitiki inezinzuzo eziningi: i-travmobezopasnost, ukukhululeka, ikhono lokwenza izinto ezihlukahlukene kanye nokusetshenziswa kwezigqoko ezengeziwe zokuzivikela (isibonelo, ukuhogela), futhi -kuvikeleka okunokwethenjelwa ngokumelene ne-UV-ray. Impendulo kuphela - le nto isheshe "isuliwe" futhi igwetshiwe. Amalazi anama-glass lens abhekwa njengengaphephile ngenxa ye-fragility yabo futhi awafaneleki ngendlela yokuphila esebenzayo.
Amalensi
Ngokuvamile, izibuko zikhiqizwa ngamalensi ajwayelekile avikelayo. Kodwa kwakukhona izingubo eziningi "ezigcotshwe". Isibonelo, ukugqumisa ukuthuthukisa ukuhlukana, kususa i-glare eyimpumputhe. Amalazi anama-lensi anjalo anconywa ikakhulukazi kwabashayeli. Hlola ukuthi ngabe imodeli yakho inemibala egxilile (ngendlela, ngokukhethekile ku-Polaroid), ungayithola esitolo se-optics ngesikrini esikhethekile noma isitaki. Okokuqala udinga ukubheka ngaphandle kwezibuko, bese-kuzo. Uma isithombe sibonakala esibukweni, ongazange usibone ngamehlo, khona-ke ama-lens akho ahlungwa.
Ukugqoka okuphikisayo (okuphikisana nokuphikisana) - kususa i-glare kanye "nemifanekiso engcolisayo" ngemuva kwe-lens. (Yilapho lapho ngokuzumayo ubona ngaphakathi izibuko zakho ukubonakaliswa kwezinto ezikulandelayo, noma ngisho iso lakho). "Izithombe ezidabukisayo" zimbiza ukucaca kombono futhi zingabangela izinkinga ezinkulu, ikakhulukazi uma ushayela ebusuku.
Amalensi we-photochromic, aphinde abizwe ngokuthi ama-chameleons, amnyama noma alulame kuye ngokuthi amandla akhanya kangakanani. Ikakhulukazi zilula kubantu abanezinkinga zombono abangafuni ukushintsha izibuko emgwaqweni. Abantu abaningi, ngeshwa, abazi ukuthi bangakhetha kanjani izibuko ezilungile, kodwa ngezincomo zethu uzothola okuningi.
Ukugqoka i-Mirror - okungafani nokukhanya okuqhathaniswa nama-lens avamile, kanye nokukhipha imisebe yokushisa. Ama-lensi anjalo anconywa ikakhulukazi ukubhukuda nokuqhwa.
Uma ugqoka izibuko ngama-lens ezinemibala, futhi izwe elizungezile liye lashintsha umbala kakhulu, wazi: unefake ekhaleni lakho. Amalensi aqinile agcina yonke imibala yemvelo, kuphela eguqulela umthunzi kancane. Ama-glass lens multicolored kubantu abanesithakazelo sokubona umbala onembile, isibonelo kubashayeli, bangadala izinkinga. Ukuhlukumeza umbala ojwayelekile wemibala egameni lombala owodwa ngokuphawulekayo kudlulisa ukunakwa, umuntu ogqoke izibuko ezinemibala akhathele ngokushesha.
Okusemandleni kunawo onke ama-grey (kusuka emthunzini omnyama kuya ojulile, cishe omnyama) futhi obomvu. Kulokhu, i-gray imhlinzeka ngombono wangempela, umbala obomvu - obala kakhulu, kodwa uhlaza luba luhlaza futhi imibala ekhanyayo - i-paler. Kubashayeli, ukuphuzi kuvame ukuphakanyiswa (ekukhanyeni okuncane). Lesi sihlungi sinciphisa ubunzima bamehlo, sithuthukisa ukuqonda kwesikhala ngokujula (ingozi yengozi ihlolwe ngokucacile). I-Orange iklanyelwe ukunciphisa umphumela wokuphazamisa wokukhanya ebusuku. I-Green inikeza izinga eliphakeme lokuphambene ezimweni eziphansi zokukhanya futhi ivikela kusuka elangeni elikhanyayo.
Gwema izibuko, izwe ocabanga ngalo (ngokoqobo) oluhlaza okwesibhakabhaka nokubomvu. Kuzo, usengozini yokuchitha umbono wakho ngokoqobo ngehora elilodwa. Iqiniso liwukuthi le mibala inegalelo elibi emehlweni ethu. I-predominance ye-blue-violet ingxenye ye-spectrum ivimbela ijubane lokucabanga namakhono omuntu wesithuthuthu. Ngokusebenza isikhathi eside kwikhompyutha - kunezinsizwa, ukukhathala, ukucasula. I-predominance ye-blue-blue - ikhulisa umphumela wokusabalalisa ukukhanya (lokhu kubangela ingozi ye-glare kusuka ezibukweni zezimoto ezizayo).
Ifomu
Ukugoba kwe-lens nakho kuyindaba, kodwa ukuqonda kakade kuxhomeke ekuziphatheni komuntu ngamunye: isibonelo, uzizwa uhle ngamalensi aphansi, futhi nge-convex - isipiliyoni singathandeki. Lokhu kungenzeka ngenxa yezinkinga ezifihliwe. Isibonelo, ngokuphulwa kombono we-binocular (ngamehlo amabili). Iseluleko siwukuthi: uma uzizwa, ngisho nokuphazamiseka okuncane, kungcono ukuyeka lesi simodeli sezibuko.
Uhlaka
Kusukela ku-frame impahla akuxhomeke nje ekubukeni kwayo, isisindo, amandla, kodwa futhi nezakhiwo ze-allergenic, lapho isikhumba singasabela ngokungathandeki ukuxhumana nalezi zinto zokusebenza. Ukuguga kwezifo ngokuvamile kubangelwa i-nickel, esetshenziselwa ama-alloys amaningi. Insimbi engenasici, i-titanium, igolide nesiliva kubhekwa njenge-hypoallergenic. Amafolda enhlobonhlobo, njengoba ama-nosoupory namathempeli, exhumana nesikhumba, zenziwe nge-silicones, i-acetate, amanye ama-plastiki noma izinsimbi. Kumele kukhunjulwe ukuthi ezinye ze-silicones nazo zingabangela ukusabela okweqile.
Kubuntu bezemidlalo
Khetha ngokukhethekile ngokucophelela izibuko zezemidlalo. Amafreyimu kufanele abe njengokukhanya futhi okuqinile ngangokunokwenzeka, anamathempeli aguquguqukayo ahlinzeka ngamapulangwe ekhaleni elungiswayo, aqoshwe ngezinto ezikhethekile, ukuze izibuko zingagodli.
Ukuze uhamba ngebhayisikili uthole izibuko ngesigqoko esibukweni, ama-lensi ezinamabala aluhlaza anombala obomvu nokukhanya, i-photochromic. Imibala: zonke izinhlobo ze-brown futhi ezinye-ezimpunga futhi eziluhlaza. Ukuze uhambe ngemoto, insabala, imbala eluhlaza-grey, imibala emibala kungcono ukukhetha. Ezemidlalo yamanzi - imibala enombala obomvu neyimpunga, ukugcoba, isibuko noma i-antireflection. Nge-tennis - i-lens enombala ophuzi, o-orange, obomvu (kungcono ukubona ibhola ensimini eluhlaza), ubukhulu obuphakathi kombala. I-basketball - i-yellow, i-orange, i-grey, i-brown, i-antireflective ne-polarising.
Yini ezobekwa uphawu?
Into ebaluleke kakhulu ekukhetheni izibuko yiyona nhlobo yokuvikelwa kwe-UV. Cwaninga ngokucophelela imibhalo ebhalwe ngelebula, emagcekeni, isitika sezingilazi. Bathi okulandelayo: "I-UV-400" - izibuko zinikeza ukuvikelwa okuphelele ngokumelene ne-ultraviolet, lokhu okubhalwe kumamodeli "ahloniphekile" akunakwenzeka, kusukela manje ukuvikelwa okugcwele kusuka ku-ultraviolet kunikezwa izinga lokukhiqiza.
Emkhakheni wezibuko kumele kube yi-CE yokumaka: ngokulandelana kwayo ukuhlukaniswa kwesilazi sosizi ngezigaba ezinhlanu (okuchazwe izibalo ezivela ku-0 kuya ku-5), kuye ngokuthi kubonakala kangakanani ukukhanya okubonakalayo - kusuka ekukhanyeni kuya emnyama. Amalensi esigaba saso asilahlekelwa 80 - 100%, owokuqala - 43 - 80%, owesibili - 18 - 43%, ukukhanya okwesithathu - 8 - 18% no 4 - 3 - 8% okubonakalayo. I-Zero neyokuqala zibizwa okuthiwa izimonyo, noma isithombe, izibuko. Owesibili kufanelekile ukuvikelwa kwelanga edolobheni elisezingeni eliphakathi. Okwesithathu - ungaya olwandle ngokuphepha, futhi okwesine - ezintabeni ezimbozwe iqhwa. Isimiso yilokhu: kungcono ukuhambahamba edolobheni ogwini kunalesi vice.
Ngisho nasezigodini ikhodi yesimodeli, ngenxa yokuthi ungalawula uhlaka olufanayo noma ingxenye.
Ungayithenga kanjani?
Ukuya "umlindi wamehlo", khumbula ukuthi izibuko ezinhle nezikhwalithi azikwazi ukubiza okungaphansi kwamaRandi 200 (ngaphandle kwesaphulelo). Ama-fake aphansi angama-dollar angu-20 kuya kwangu-80, athengiswa ekushintsheni nasematayini athengiswayo emakethe, hhayi nje kuphela aphumule ngokushesha, aqale, kodwa futhi alimaze amehlo.
Ngakho-ke, indlela yakho eya ezitolo ezikhethekile ze-optics. Iphuzu elilodwa elilodwa: ngaphambi kokuthenga izibuko kufanele unikezwe (esikhungweni esiqinile) ukuphuma emgwaqeni. Ekamelweni awukwazi ukuthola ukuthi ikulandela yini. Isimiso esengeziwe sokukhetha amaphuzu amahle singaba yiqiniso lokuthi ubona ngosuku oluhle futhi olulula kunokungenawo. Ngendlela, noma kunjalo, ungaboni ilanga - kuphela ezintweni. Lena iphutha elivamile labantu abahlola lapho bethengisa ukuthi ukukhanya okungahle kutholakala kanjani izibuko. (Ungaboni ilanga njengesikhuphuka esivela ku-cartoon!). Ngisho nama-super-dark lens coatings awavikeli ngokuphelele amehlo akho.
Amathrendi wefashini
Futhi-ke, akufanele sikhohlwe ukuthi izibuko azigcini nje kuphela ukuvikelwa emisebeni ye-ultraviolet, kodwa futhi nezesekeli zemfashini. Ngakho-ke, kule nkathi, kukhona amafolda epulasitiki amakhulu phansi. Kubantu - izinhlobo ezifana "ne-aviator", kubantu besifazane - "izinhluzane". Imibala: emnyama, emhlophe, emnyama, emnyama. Emuva ngo-2010, ukungafani kwakuthandwa kakhulu. Isibonelo, uhlaka olumnyama namalensi aluhlaza. Ama-lens angama-topical ane-color gradient, okungukuthi, avela phezulu angaphezu komnyama kunokuba avela ngezansi.
