Nzira yekuziva sei ukuru hwepfungwa dzevana nevakuru?

Iye zvino magirazi akatanga kushanda kwete chete chekudzivirira kana kugadzirisa basa, asiwo anoshumira sefashoni inoshandiswa inogona kuchinja maitiro evanhu uye kubatsiridza chimiro chemavara. Iko kune maitiro akasiyana-siyana anoshandisa lenzi, uye kunyange mafomu akawanda emapuranga. Asi usati watenga mufananidzo unoda kuziva kuti ungaziva sei ukuru hwegirasi, kuitira kuti ivo vagone kusununguka uye vakasununguka kupfeka.

Kururamisa kugadzika kwezvinhu zvakataurwa kunokosha zvikuru, nokuti zvichange zvakasuruvara zvikuru kana kutenga kunodhura mushure memaminetsi mashomanana apfeke kuchapedza zvimwe zvikamu zvechiso kana, zvakatarisa, zviwisire panguva yechipfuva.

Kana ruzivo rune zviyero zvisingasviki nemiganhu yako yeanthropometric, saka usatenga kunyange mufananidzo waunoda.

Nheyo dzekasiyamu yakaenzana magirazi

Kuti urege kukanganisa pakusarudza fomu yakakodzera, unoda kuziva kuti ungaziva sei ukuru hwegirazi. Kuti ubatsire pakusarudza fomu, kune maverengi akawanda anowanzoita zvinokubvumira kuti usarudze mhando yakakodzera pasina basa rakawanda. Kune zvine chete:

1. Iyo yakafara ye lens.
2. Iyo yakakwirira ye lens.
3. Ihwo hupamhi bhiriji pakati pemarimu emarori.
4. Kureba kwetemberi.

Kana ukasarudza magirazi ane progressive lenses, imwe yemiganhu yefurati ndeyekukosha zvakanyanya: kureba kwemavhenekera emwenje. Munguva yekusarudzwa kwemashure akareba mabheiri, kureba kwema-lens kunofanirana nekupfuurira kwekugadzirwa kwemazizigisi emarara.

Zvakanakisisa kutaurirana naOphthalmologist kana muongorori wezvechiremba anozobatsira kutarisisa kushaiwa kwekusarudza. Nokuda kwechikonzero ichi, vanoongorora kubvumirana kwehuwandu hwenzvimbo yekusimudza yakasarudzwa iyo inoratidzwa musarudzo yakasarudzwa yemasikironi lenzi, pamwe nehupamhi hwemafuro akasarudzwa aya magirazi.

Kukura kwegirazi pamakumbo avo

Iyo mikuru mikuru iyo inobatsira pakusarudza magirazi inoratidzwa mumamilimita, inogona kuonekwa mukati mukati me-arc arch. Iyi nhamba ichakubatsira iwe kupindura mubvunzo - kuti ungaziva sei ukuru hwemashoko. Ray Ban, Oakley, Persol nevamwe vanogadzirisa mararamiro emagetsi ezvinhu izvi zvinoratidzira mitsara mikuru yezvigadzirwa zvavo. Somuenzaniso, unoona nhamba 60 - 14 145 mukati mukati metemberi, dzinofananidzwa nezvikwangwani zvinotevera: hupamhi hwomukova, mushure mokunge dash kana kuti nekona yekona unoratidza hupamhi bhiriji, uyezve, kuburikidza nenzvimbo, - nhamba inoratidza urefu hwetemberi.

Chiratidzo chehupamhi hwechitarisiko lens hachiwanzoratidzi.

Uye pane mamwe magirazi echitengo chisingabatsiri, unogona kuwana nhamba imwe chete - inofananidzwa nehurefu hwehutano huno.

Sezvo mutemo, mapuranga emagetsi emagetsi ane makuru kudarika mapurisa emagalazi pamwe nekugadzirisa basa.

Sarudza rutivi rwechiso

Zivo yakarurama yehupamhi hwechiso ichabatsira kugadzirisa mubvunzo - kuti ungaziva sei ukuru hwemashoko. Pamba, kuyera upamhi hwechiso chiri nyore, asi zvinogoneka.

Kuti uite izvi, unoda mapensela maviri kana mapeji kuti aiswe shure kwekunzwa kwako, uye nzvimbo iri pakati pavo inoyerwa nemutongi.

Ngatiratidzei imwe nzira nzira yekuziva nayo ukuru hwegirazi, tichifunga nezvehukuru hwe lens. Unofanidza kubvisa kubva paupamhi hwechiso chako hukuru hwechivharo pamusoro pebhiriji yemhino dzako, uye kubvisa imwe masentimita gumi. Nhamba inoguma inofanira kugoverwa kuva mbiri. Chigumisiro ndicho chimiro chakakosha che lens, iyo yakakodzera chiso chako.

Nzira yekuziva sei ukuru hwegirazi remwana?

Vana vakanyanya kuoma kugadzika kuti vaenzanise zviso zvavo zvepasita. Mukuwedzera, zviratidzo izvi zvinoramba zvichichinja, kunyanya maererano nekukura kwebhiriji remhino. Bhiriji iri mumagirazi evana rinokosha zvikuru, nokuti ndeyekuchinja kwechigarire muhupamhi hwayo kuti unoshandura magirazi ako mushure meimwe nguva.

Kusvikira ava nemakore matanhatu, ukuru hwebhuririro remhino hunosiyana zvishoma, uye pamakore manomwe kana mapfumbamwe mhino inotanga kusvika pakukura kwayo.

Kuti uone miviri mikuru iyo ichadiwa kutenga mabirazi, zviri nani kushandisa rubatsiro rwevanyori kana kuzviita iwe pachako pahope dzomwana.

Mirairo yekusarudza magirazi nehukuru

Kuti uzive nzira yakarurama yekugadzirisa hukuru hwemashoko, unofanira kutevera mazano akawanda paunenge uchiita zviyero zvekutanga:

• Uwandu hwakazara hwomukati hunotsanangurwa sehuwandu hwebhiriji uye upamhi hwemakiro maviri, uye hupamhi hwezvibatanidza hinge huwedzerwa kwavari, iyo iyo temberi inosanganiswa pamusana weganda. Nhamba inowanikwa semugumisiro, sekutonga, iri mumakiromita mana kusvika kune gumi.
• Zvose zviyero zveganda remaziso rinofananidza nehupamhi hwechiso apo magirazi anosarudzwa uye haafaniri kuenzana nemufananidzo wekupedzisira nemamwe maviri kana matatu mamita.

Mazano ekutsvaga pfungwa

Zvakanakisisa kutenga iyo yakatsanangurwa zvishandiso mune zvigadzirwa zvakasiyana kana optics. Mukuwedzera, nyanzvi dzinokurudzira kusarudza mabhuku akakurumbira kana kuti akajairika uye magirazi. Uye nokuda kweizvi zvakakosha kutsvaka rubatsiro kubva kumuongorori wemagetsi, uyo anonyanya kuwanikwa mune rimwe rega rekutengesa rinotengesa magirazi.

Paunenge uchitenga magirazi iwe pachako, tungamirirwa nehukuru hwekare, hwakatengwa kare.
