Spectacle izilungiso - kuyini? izibuko: izici jikelele, incazelo, zilwane, izithombe

angaboni kahle seziyinto ejwayelekile namuhla. Nokho, zikhona amadivaysi optical, ngokuvumela ukuxazulula le nkinga. Bona ukuthi umuntu enempilo, ekusizeni izibuko. Kuyini lokhu? Lokhu imikhiqizo ekhethekile ezisetshenziswa kokubili kwalungiswa izinkunga zokubona, futhi yokuhlala.

Ingozi ukuthenga imikhiqizo esezingeni eliphansi

Namuhla, amadivayisi we-optical sokulungisa umbono zidayiswa cishe kuyo yonke indawo. Abakwazi ithengwe ngisho ku underpasses. Kodwa kungakhathaliseki ukuthi ukuthemba izinga yabo? Abantu abaningi angikaze ngimbone umkhiqizo amehlo enjalo, njengoba izibuko zokulungisa. Kuyini abazi. Ebhekene nazo isidingo ukuthenga imikhiqizo enjalo, benza amaphutha. Ngenxa yalokho, abanazo emibi:

• umuntu eseqala ukuzwa ukukhathala emehlweni umbono siyaqhubeka siba sibi;
• Uhlaka yekhwalithi ephansi obulimaza isikhumba, okuholela komzimba;
• izibuko bheka inharmonious, ngoba umnikazi wabo akazange unamathisele ukubaluleka ekuveleni imikhiqizo.

Yini oyibhekayo?

Ukukhetha izibuko, ukuthi iyini - odinga ukukwazi ngempela. Lokhu izimpahla amehlo, kusho ekuthengeni yayo kufanele kuthathwe wemfanelo. Udinga ukuthenga it kuphela nokucwala of yokukhanya. The main ingxenye ingxenye mkhiqizo ukubeka. eziningana zezinto eziphilayo yayo ungabahlukanisa:

• One-piece. It Frames lens ngokuphelele.
• Poluobodkovaya. It has onqenqemeni engenhla kuphela. Iphinde fixed lens. Glass khulula kusuka phansi.
• Rimless. imiphetho sintula. Shackle exhunywe ngqo ingilazi. ozimele okunjalo ngoba izibuko zokulungisa aqukethe i-elementi, nokubopha kubo.

Njengoba metal zokwakha, kanye polymers. Ozimele ezenziwe acetate, kungaba kubhekwe uhlobo eseyintsha.

Uma ufuna ukuba ngumnikazi imikhiqizo ephezulu, qiniseka ukubona ukusebenza. Imibhalo wabonisa GOST 51193-98. Kukhona amabhizinisi abonakele ukuthi udala izibuko, ukuthi kuyini, abaqondi. Kufanele kwenziwe ngokuhambisana iziqondiso ezingokomthetho. Bona lokulawula Ukucaciswa jikelele.

Amazinga kungacacisa ukuthi noma ngabe imikhiqizo obhekene ukulungiswa izidingo wezokwelapha. amathuluzi Optical wadala ezimweni esikhashana, ingozi empilweni yomuntu. Futhi lapha yenziwa ngokuhambisana zonke izidingo GOST izibuko angathengwa kalula.

Yini lens ukukhetha?

Ukuze kukhiqizwe izibuko asetshenziswa amaminerali ingilazi futhi izinto odabuka eziphilayo. Esimweni sokuqala kukhona into esobala. Kumiswa It is emva Ukupholisa enamandla ngaphambilini elicibilikile izingxenye ingilazi-ukwakha. I lens eziba umphumela kuyizipho ngempela laba nzima, kodwa simelane ngokuphelele ukucindezeleka mechanical. imikhiqizo Plastic ngokuphambene ukala kancane. Nokho, izibuko ezifana zidinga enamathela ezengeziwe ukuvimbela ukunwaya.

Indlelanchubo yekusebentisa izinkampani Russian kanye angaphandle

abakhiqizi Domestic kahle ngempumelelo ukukhiqizwa lens for izibuko staining imiklamo. Basebenzisa izinto ezahlukene solar ukulawula izakhiwo. Ngokuvamile ungabona umkhiqizo grey nonsundu. Nokho, emakethe kukhona imibala te ngaphezulu: green, blue, ophuzi. BaseMelika uncamela grey ingilazi, futhi baseYurophu - brown.

izinkampani Russian avame ukuba ukukhetha ngokungadingekile umbala. Phesheya, ngakolunye uhlangothi, bathambekele acabangele yokuphila amakhasimende. Laba bameleli be-ukuzibonakalisa zokudala ukunikela izibuko abanamalensi grey. Imikhiqizo ukunciphisa nalokho ukwakheka aluhlaza okwesibhakabhaka kanye noluhlaza okwesibhakabhaka kancane ayegcwele. Brown ingilazi, kuyinto efiselekayo nika abashayeli ngokuvamile abantu bachithe isikhathi esiningi emgwaqweni. Uma isiguli kubalulekile silondoloze ikhwalithi umbala futhi sandise Ngokuphambene ngesikhathi esifanayo, kudinga oluhlaza lens. Ziyakwazi abameleli nasemikhakheni efana isithuthuthu bamabhayisikili abaphambili, abacibishelayo, abadlali.

Kukholakala ukuthi izibuko abanamalensi ophuzi abe look sporty ehlukile. Kodwa ochwepheshe batusa kubo kuphela abantu abathintekayo ithenisi. Babe ngcono ua umdlali on inkantolo.

Uma ebekiwe izibuko, ukubuyekezwa kudingeka uhlole ngempela - abanitshela eziningi imininingwane ewusizo. Amazwana kungaba ehlukene, ngoba lapha, njengoba kwaba njalo endabeni ka-izidakamizwa, konke kuncike nesineke futhi umkhiqizo izici yomenzi ethize.

nemingcele ezibalulekile

Uma umbono kuyahlukahluka kusuka 0.5 kuya 0.05, kwakudingeka zamehlo telescopic. Ziyakwazi ngempumelelo ngephutha yezokubona, ngokwanda okukhulu ubukhulu bezinto. Umkhiqizo ekhona engeyinhle kanye ne-lens omuhle.

izibuko Prism zenzelwe iziguli izifo of the imisipha iso. amaphrizimu ababili, okuphakathi samanje, refract imisebe i-engela 90 degrees. Ngenxa yalesi umuntu angakwazi ukubeka incwadi esifubeni sakhe, futhi esimweni ukuze ubone ukuthi okulotshwe kuyo. yokukhanya enjalo inikeza esisemqoka ukwesekwa iziguli esembhedeni ngenxa yokugula.

Kwezinye izimo, bamehlo linqume izibuko sesibuko zokulungisa. Kuyini lokhu? Sinenkosi izakhiwo lembhali, asetshenziswa abantu hemianopsia sohlangothi olulodwa.

Ochwepheshe njalo ukubhala isithako somuthi nokusetshenziswa kwawo izibuko, eliqukethe amasethingi abaluliwe:

• ibanga esasihlukanisa izikhungo lens optical komunye nomunye;
• sibalo ngenhla kokubili amehlo;
• ukufuduka kahle isikhungo;
• injongo yokukhanya.

Ukuze sithole amandla optical okwasetshenziswa - dioptrimeter. Kuyinto esihlupha bonke izifundo zamehlo. Idinga isikhathi ukuvakashela udokotela wamehlo ukunqanda lesi sifo ngo zisaqala.

onobuhle ezithile zidinga izibuko ukulutheka, kuyilapho abanye kuhluke uhlamvu linesizotha. Ziyinkimbinkimbi ngokuvamile kwenzeka nge yokukhanya, okuvumela ukuba uxazulule izinkinga ezithile, njengabaphostoli astigmatism, isibonelo. Yingakho ke ngezinye izikhathi izihloko, akhethwa ochwepheshe, neminye imiphumela emibi. Sinenkosi ukujwayela kancane kancane.

Manje ezidayiswa izibuko wenza ukuthi izithombe ukunikela ukubukeka khona lapho ngaso leso sikhathi. Ngezinye izikhathi amakhono abo optical idlule kuvunyelwe. Kufanele uqaphele. ngezinye izikhathi Amakhasimende wathenga amehlo yokukhanya kusengaphambili.

Odokotela batusa ayeke egqoke izibuko zokulungisa onobuhle ngabanye njalo. Kungcono ukusebenzisa kwabo ngezikhathi ezithile, isibonelo, uma ufika beshayela. Ungakwazi sizigqoke uma usebenza nge izingxenye, incane ngobukhulu.

Ukukhethwa imikhiqizo ngokuhambisana uhlobo lomuntu

Ngakho, i-theory okuyingxenye ufundwa, Manje singakwazi ukucabanga mayelana nokudala ngendlela evumelanayo izibuko. Akufanele zizizwe zilahliwe imibono yabo kusuka kumnikazi yabo. Yiqiniso, ungakhetha ukuma umkhiqizo ngokwayo. Kodwa akufanele sikhohlwe imithetho embalwa ezibhekwa eziyisisekelo.

1. ozimele ingasabeli futhi poluobodkovye kungukuthi Kunconywa ukuba abanikazi uhlobo side lomuntu. Abantu abanjalo zingcono ukuthenga izibuko naphakathi.
2. Imikhiqizo kokwehla okusezingeni eliphezulu, kuhle abanikazi ebunzini ububanzi.
3. Izingilazi nge look ephansi ayejikijela ukuba esihle nge ikhala elikhulu kubantu. Ungasebenzisa Uhlaka omkhulu shades amnyama. Kusetjentiswa kahle futhi ibhuloho double. iseluleko Okufanayo kumele inikwe abantu nge kwesilevu ezinkulu. Uma zonke izici kobuso abantu kukhona ngokulingana, ukusetshenziswa kwanoma yiluphi uhlobo amaphuzu kuvumelekile.

Kwembala

Abantu ne izinwele blonde kukhona izibuko efanelekayo zokulungisa Kwakwakhiwa ngesiliva noma umbala igolide. umbala Bronze sibukeka sisihle kusuka abanikazi ngezinwele ezibomvu, kuyilapho Brown batusa ensundu, segolide noma obomvu. Brunette, kunalokho, kufanele kubhekwe abamnyama.

Ukukhetha ngokuhambisana ikhabethe

izibuko okuqinile zivumelane ngokuphelele kuhlanganiswe suit ibhizinisi. izixazululo Brighter Kunconywa isitayela emgwaqweni. Ziyakwazi ethandwa nje isizukulwane esisha. imikhiqizo ezinjalo zivame atholakala phakathi yokukhanya nge polymer ozimele.
