Munzvimbo yekugadzirwa kwemaziso, dhizaini yelens inonyanya kuiswa mumhando mbiri: spherical uye aspheric.Aspheric lenses, inosundwa nekutsvaga kutetepa, inoda shanduko mune lens curvature, ichitsauka zvakanyanya kubva kune yechinyakare spherical lens pamusoro curvature.Dhizaini yedenderedzwa, yaimbozivikanwa, yakatambudzwa nekuwedzera kutsauka uye kukanganisa.Izvi zvaiwanzokonzera nyaya dzakataurwa dzakadai semifananidzo isina kujeka, kuona kwakakanganiswa, uye maonero mashoma.
Iye zvino, iyo aspheric dhizaini yakabuda sesimba rekugadzirisa, kugadzirisa izvi zvinokanganisa zvinotaridzika zvinobudirira uye nekupa mhinduro inopa lenses iyo isiri chete yakareruka uye yakatetepa asiwo yakafanana flat.Zvakakosha, kufambira mberi uku hakukanganisi malenses 'akasarudzika maitiro ekupikisa, kuve nechokwadi chekupfeka zvakachengeteka chiitiko.
Traditional spherical lenzis ane inocherekedza pasi - zvinhu zvinotariswa zvakatenderedza periphery yelenzi zvinoratidzika zvakamonyaniswa, zvichimanikidza munhu akapfeka maonero.Muzera umo tekinoroji inoramba ichishanduka, aspheric lenses - yechokwadi yekuona kushamisa - kuderedza kutsauka pamucheto welens, ichiwedzera zvakanyanya ndima yekuona kusangana nezvinodiwa nevatengi.Aspheric lenses ane flatter base curve uye akareruka, achinatsiridza hunhu uye kunaka kukwezva.Kunyanya muzviitiko zvesimba rakanyanya refractive, ivo vanodzikisa zvine hungwaru kukanganisa kwemaziso, vachivaita sarudzo yakanaka kune vatengi vane yakakwira mishonga inodiwa.
Iyo inotsanangura chimiro cheaspheric lenses ndeye yakasarudzika pamusoro curvature.Iyi aspheric dhizaini inopa akati wandei mabhenefiti pamusoro pechinyakare spherical lenses:
1.Clarity: Yakabatwa neyakagadziriswa coating process, aspheric lenses inopa muenzaniso wekuona maitiro, kuve nechokwadi chakajeka uye chakasununguka kuona chiitiko.
2.Comfort: Saka chiedza ivo vanenge vasingaoneki, aspheric lenses inoderedza 'huremu' pameso ako, zvichibvumira kupfeka kwakasununguka uye kusina simba.
3.Natural Vision: Kugadzirwa kwavo kweaspheric kunoderedza kukanganiswa kwekuona, zvichiita kuti pave nemafungiro echokwadi uye akarurama.
Kuenzanisa spherical uye aspheric lenses ezvakafanana zvinhu uye kunyorerwa, aspheric lenzi anomira seanoti nyangarara, akatetepa, uye anopa mamwe echokwadi uye akasununguka ekuona zviitiko.Kucherekedza kuvharwa kwechimiro chelenzi chinopesana nechiedza kunoratidza kuti maratidziro kubva kuspherical lenzi anowanzo kutwasuka (kunze kwemalenzi emagetsi epamusoro);aspheric lenses, zvisinei, anoratidza yakakura kukombama nekuda kwekusiyana-siyana curvature pamusoro penzvimbo yavo.
Mipendero yemativi echinyakare spherical lenzi haingoratidzike yakakora asi zvakare inomonyanisa nekumonyorora maonero ezvinhu, chiitiko chinozivikanwa semufananidzo aberration.Kuti uwane dhizaini yakareruka, yakakwirira refractive index zvinhu zvakashandiswa mukugadzira lens.Uyezve, kana ikatariswa nemalenzi akaita denderedzwa, kutarisika kwechiso chemupfeki kunooneka kwakamonyaniswa.Aspheric lenzi, nekusiyana, inoderedza zvese zviri pakati nepakati uye kumucheto ukobvu, zvichikonzera slimmer lens inobvisa peripheral aberration, nekudaro ichipa yakasikwa yekuona chiitiko.
Aspheric lenses inopa nzvimbo yakafara uye isina curved yekuona kumicheto, ine kushoma kwemufananidzo kubvongodza, ichipa iyo mifananidzo yakasarudzika.Aya lenzi akaomesesa katatu kupfuura mamwe matenderedzwa, zvichiita kuti anyatso kukodzera kune vechidiki vanopfeka.Nezvimwechete -5.00DS prescription, aspheric lenses ane 26% akareruka pane spherical lenzi.Chiso chavo chakati nyangarara chinova nechokwadi chekuona kwechisikigo, kusakanganiswa kwenyika, zviri pedyo nekure, zvichideredza kuneta kwemaziso kwenguva yakareba.
Yakanakira vanopfeka magirazi emaziso ekutanga, kunyanya vadzidzi nevashandi vemuhofisi, aspheric lenses inoderedza zvakanyanya kusagadzikana kwekutanga kunoenderana nekupfeka magirazi.Ivo zvakare yakanakisa imwe nzira yevashandisi velens yekubata, inoshanda seyekuchengetedza maziso kumba.Aspheric lenses anonyatso tevedzera chiono chechisikigo, zvakangofanana nechiitiko chine contact lens.Ivo vakakwana kune avo vanosarudza kuderedza chirevo chavo chepamusoro, vanoshuvira kudzivirira kutaridzika kwemaziso madiki ane myopia magirazi, kutsvaga kurerutsa huremu hwemalenzi avo, kana kuve neyakasiyana refractive zvido zveziso rega rega.
Aspheric lenses inogona kupa epakati refractive index lenses yakafanana slim uye flat kutaridzika seyepamusoro refractive index lenzi, kuderedza kumucheto kutsauka uye kupa kune yakafara ndima yekuona inogutsa zvese zvinodiwa nevatengi.
