Chimwe chezvinhu zvakakosha zvekufunga nezvacho kana uchitenga magirazi emaziso ekunyoreswa ndiko kukora kwemalenzi.Ukuru hwema lenses ako haungokanganisa kutaridzika kwemagirazi ako, asiwo kunyaradza kwavo uye basa.Kuti uve nechokwadi chekuti waita sarudzo chaiyo, zvakakosha kuti unzwisise izvo zvinokanganisa girazi regirazi ukobvu.
Chinhu chekutanga chekufunga nezve simba remishonga.Kukwirisa kwaunonyorerwa nachiremba, ndiko kuwedzera kwaungada malenzi akakora.Mitemo yakasimba inowanzo sanganisira ma curvature akasimba, ayo anoda zvimwe zvinhu kuti awane kururamisa kuona kwakakwana.Kana iwe uine mishonga yepamusoro, ungada kufunga nezve high-index lenzi.Aya malenzi akagadzirirwa kuve akatetepa uye akareruka kupfuura echinyakare lenzi, achiaita sarudzo yakanaka kune vanhu vane myopia yakakwira.
Chimwe chinhu chekufunga nezvacho ndeye lens zvinhu.Zvishandiso zvemalenzi zvakasiyana zvine mareferensi indexes akasiyana, ayo anokanganisa kuti mwenje unokotama sei kana uchipfuura nemulenzi.Kazhinji kutaura, zvinhu zvepamusoro-index zvine yakakwira refractive index, zvinoreva kuti vanogona kukotama chiedza zvakanyanya.Naizvozvo, marenzi epamusoro-soro akatetepa pane akajairwa epurasitiki lenzi kune imwecheteyo simba rekuraira.
Mukuwedzera, kusarudzwa kwemafuremu kuchakanganisawo ukuru hwema lenses ekuona.Mafuremu akazara-asina rimless anowanzo kukwana malenzi akakora, nepo mafuremu asina rim kana semi-rimless achida malenzi matete kuti akwane.Saka kana iwe uchida imwe mhando yefuremu, iva nechokwadi chekufunga kuti inokanganisa sei kukora kwemalenzi ako.
Chekupedzisira, kukwidziridzwa kwemalenzi senge anti-reflective coatings kunogona kukanganisa ukobvu hwemagirazi ako.Aya machira anoderedza kupenya uye kufungidzira pamalenzi, kuvandudza kunyaradzwa kwekuona uye kujeka.Kunyangwe zvisingakanganisi zvakananga kukora kwelenzi, vanogona kuita kuti lens iite seyakatetepa nekuda kwekuderedzwa kwechiedza.
Muchidimbu, pane zvinhu zvakati wandei zvekufunga nezvazvo pakusarudza iyo chaiyo girazi reziso ukobvu.Simba rako rekunyorerwa, lens zvinhu, sarudzo yefuremu, uye makwidziridzo emalenzi ese anoita basa mukuona ukobvu hwelens.Nekubvunza nyanzvi yemaziso, iwe unogona kuita sarudzo ine ruzivo iyo isingangokupa iwe yakanakisa gadziriso yekuona, asi zvakare ive nechokwadi chekuti magirazi ako akasununguka uye akashongedzwa.
