Kuphatikiza pa aesthetics, muyenera kumvetsera kwambiri izi posankha mafelemu

Anthu ambiri nthawi zambiri amangoganizira za aesthetics posankha mafelemu a magalasi a myopia.M'malo mwake, zisonyezo zaukadaulo za kuwala ndi kuyeza kwa mafelemu agalasi ndizofunikira kwambiri pakutonthoza kwa ogula ovala magalasi.Kusankhidwa kwa mafelemu a magalasi a maso kuyenera kuganiziridwa kuchokera ku magawo atatu: mawonekedwe a aesthetics, ntchito ya chimango ndi kuvala chitonthozo.

Mafelemu a Spectacle amabweranso kukula kwake.Nthawi zambiri, magawo monga kukula kwa chimango chowonera amalembedwa pakachisi, mlatho wa mphuno kapena pachizindikiro.Mwachitsanzo: 54 pakamwa 18-135, kutanthauza chimango m'lifupi ndi 54mm, mphuno mlatho m'lifupi ndi 18mm, ndi kachisi kukula 135mm.Choyamba, muyenera kudziwa kukula kwa magalasi omwe amakuyenererani.Mukhoza kuyang'ana magawo a magalasi ogulidwa, kapena kuyeza magalasi ndi wolamulira kuti mutenge deta, kapena pitani ku sitolo ya kuwala kuti muyese, ndiyeno lembani kukula kwake komwe kumakuyenererani.

Dziwani digiri ya maso anu

Digiriyi imaphatikizapo masomphenya apafupi/akutali a maso onse awiri, ndi mtunda wa interpupillary.Ngati pali astigmatism, mlingo wa astigmatism ndi olamulira astigmatism ayenera kuperekedwa.Axis ndi ngodya ya astigmatism, ndipo astigmatism sangathe kusonkhanitsidwa popanda axis ya astigmatism.Ngati simukudziwa digiriyo, mutha kupita ku shopu yamagetsi kapena kuchipatala kuti mukayeze digirii.Digiri yachipatala ndiyothandizanso kwambiri, ndipo mutha kuyeza digiriyo popachika nambala ya dipatimenti yamaso.

Chizindikiro cha Optometry

Kumbukirani kuyika optometry (ndiko kuti, yesani kuvala choyikapo kuti muwone tchati cha diso kapena kuyang'ana patali, musatenge mndandanda wa optometry wa pakompyuta ngati lamulo lopatulika, ngakhale mutakhala ndi mndandanda wa optometry pakompyuta, muyenera kuyika optometry pamanja. ndi kusintha izo), nthawi yoyamba kuvala magalasi ndi Amene kawirikawiri kuvala magalasi ayenera amaika refraction, apo ayi n'zotheka kuvala chizungulire.Ponena za mtunda wa interpupillary, mtunda wa interpupillary ndi 60mm-70mm kwa amuna ndi 58mm-65mm kwa akazi.Pakati pa wophunzira ndi mandala amafanana ndi omasuka kwambiri.

Kusankha magalasi

Nthawi zambiri, digiriyo siili yokwera (0-300), ndipo index refractive ya 1.56 ikhoza kusankhidwa.Kwa digiri yapakatikati (300-500), index refractive ya 1.61 ikhoza kusankhidwa.800 ndi pamwamba).Kukwera kwa refractive index ya mandala, kucheperako m'mphepete mwa disolo la digiri yomweyo, ndikukwera mtengo.Tsopano zodziwika bwino padziko lonse lapansi ndi Essilor ndi Zeiss, zodziwika bwino zapakhomo ndi Mingyue, ndipo pali mitundu yosiyanasiyana yapakhomo ndi yakunja.Magalasi amawononga kulikonse kuyambira mazana ochepa mpaka masauzande ochepa.Zotsika mtengo pa intaneti!

Oyenera mawonekedwe a nkhope ndi kufanana ndi mtundu

Kawirikawiri, nkhope yozungulira ndi yoyenera kuvala chimango cha square, ndipo nkhope ya square yokhala ndi nkhope ya Chitchaina ndi nkhope ya vwende ndiyoyenera kuvala chimango chozungulira.Kufanana kwamtundu kumatengera zomwe amakonda, ndipo okhwima kwambiri amakhala ma toni akuda.Achinyamata ndi omwe ali ndi malingaliro achichepere amatha kuyesa mafelemu otchuka kwambiri a magalasi a retro posachedwa.Mtundu wa tortoise ndi nyalugwe ndi wodumpha pang'ono, ndipo ndi wa achinyamata enieni.

Kawirikawiri, ngati muli ndi maonekedwe abwino, muyenera kusankha chimango chokhala ndi mtundu wopepuka, monga pinki yofewa, golidi ndi siliva, ndi zina zotero;ngati muli ndi khungu lakuda, muyenera kusankha chimango chokhala ndi mtundu wakuda, monga wofiira, wakuda kapena mtundu wa tortoiseshell, etc.;Ngati khungu liri lachikasu, pewani mawonekedwe achikasu, makamaka amitundu yopepuka monga pinki, khofi wofiira, siliva, ndi woyera;ngati khungu ndi lofiira, pewani chimango chofiyira, sankhani imvi, zobiriwira zobiriwira, Blue frame, etc.
