Aspheric lens kana asphere (inowanzonzi ASPH pazvidimbu zveziso) irenzi ine maprofiles asiri zvikamu zvebhora kana humburumbira.Iyo asphere yakanyanya kuomarara chimiro chepamusoro inogona kuderedza kana kubvisa spherical aberration uye zvakare kuderedza mamwe maoptical aberrations senge astigmatism, zvichienzaniswa neakareruka lenzi.Imwe aspheric lens inogona kazhinji kutsiva yakanyanya kuomarara multi-lens system.Chishandiso chinokonzeresa idiki uye chakareruka, uye dzimwe nguva chakachipa pane akawanda-lens dhizaini.Aspheric zvinhu zvinoshandiswa mukugadzirwa kweakawanda-element yakafara-ekona uye nekukurumidza akajairwa lenses kudzikisa aberration.Anoshandiswawo pamwe chete nezvinhu zvinoratidzira (catadioptric systems) senge aspherical Schmidt corrector plate inoshandiswa mumakamera eSchmidt uye materesikopu eSchmidt-Cassegrain.Madiki akaumbwa aspheres anowanzo shandiswa kurovera diode lasers.Aspheric lenses dzimwe nguva anoshandiswa kune magirazi emaziso.Aspheric eyeglass lenses inobvumira kuona kwakajeka pane akajairwa "best form" lenzi, kunyanya kana uchitarisa kune mamwe mativi kupfuura lens optical centre.Uyezve, kuderedzwa kweiyo magnification effect ye lens inogona kubatsira nemirairo ine masimba akasiyana mumaziso maviri (anisometropia).Hazvina hukama nehupamhi hwemaziso, dzinogona kupa lenzi yakatetepa, uye zvakare kukanganisa maziso emuoni zvishoma sezvinoonekwa nevamwe vanhu, zvichiita zviri nani kutaridzika.
2.Spherical vs aspherical lenzi

Aspherical spectacle lenses anoshandisa macurves akasiyana-siyana pamusoro pepamusoro pawo kudzikisa kuwanda uye kuita kuti anamate mune yavo chimiro.Spherical lens anoshandisa imwe curve mune yavo mbiri, ichiita kuti ive nyore asi yakakura, kunyanya pakati pelens.
3.Aspheric Advantage
Zvichida truism yakasimba pamusoro peasphericity ndeyokuti kuona kuburikidza neaspheric lenses iri pedyo nekuonekwa kwechisikigo.Aspheric dhizaini inobvumira flatter base curves kushandiswa pasina kukanganisa optical performance.Musiyano mukuru pakati pespherical neaspheric lens ndewekuti lenzi yakatenderera ine imwe curvature uye yakaumbwa sebhasikiti.Aspheric lens inotenderera zvishoma nezvishoma, sebhora riri pazasi.Iyo aspheric lens inoderedza kukudzwa kuita kuti kutaridzika kuve kwakasikwa uye kuderera kwepakati ukobvu kunoshandisa kushoma zvinhu, zvichikonzera huremu hushoma.
