Lens aspheric ama asphere (badanaa lagu calaamadiyaa ASPH ee qaybaha isha) waa muraayada oo muuqaalkiisu aanu ahayn qaybo ka mid ah goob ama dhululubo.Muuqaalka dusha sare ee asphere-ku wuxuu yarayn karaa ama baabi'in karaa aberration-ka wareega wuxuuna sidoo kale yareeyaa aberration-ka kale ee indhaha sida astigmatism, marka la barbar dhigo muraayadda fudud.Mid ka mid ah muraayadaha aspheric ayaa badiyaa bedeli kara nidaamka muraayadaha badan ee kakan.Qalabka soo baxay waa ka yar yahay oo ka fudud yahay, mararka qaarkoodna wuu ka jaban yahay naqshadda muraayadaha badan.Curiyayaasha aspheric waxaa loo isticmaalaa naqshadaynta xagal ballaadhan oo walxo badan leh iyo muraayadaha caadiga ah ee degdega ah si loo yareeyo khalkhalka.Waxa kale oo loo istcimaalay iyada oo ay weheliyaan walxo milicsi leh (nidaamyada catadioptric) sida saxan saxan saxan oo Schmidt ah oo lagu isticmaalo kamaradaha Schmidt iyo telescopes-ka Schmidt-Cassegrain.Aspheres yaryar oo qaabaysan ayaa inta badan loo isticmaalaa isku-dhafka laysarka diode.Muraayadaha aspheric ayaa sidoo kale mararka qaarkood loo isticmaalaa muraayadaha indhaha.Muraayadaha muraayadaha indhaha ee aspheric waxay u oggolaanayaan aragti qallafsan marka loo eego muraayadaha caadiga ah ee "qaabka ugu fiican", inta badan marka la eegayo jihooyin kale oo aan ahayn xarunta indhaha ee lens-ka.Waxaa intaa dheer, hoos u dhigista saameynta weyneynta muraayadda ayaa laga yaabaa inay ka caawiso daawooyinka loo qoro kuwaas oo leh awoodo kala duwan 2 indhood (anisometropia).Aan la xiriirin tayada indhaha, waxaa laga yaabaa inay bixiyaan muraayad khafiif ah, iyo sidoo kale in ay qalloociyaan indhaha daawadayaasha sida dadka kale u arkaan, soo saara muuqaal qurxoon oo wanaagsan.
2.Spherical vs aspherical lenses

Muraayadaha muraayadaha aspherical waxay isticmaalaan qaloocyo kala duwan oo dusha sare ah si ay u yareeyaan tirada badan oo ay uga dhigaan kuwo si fiican u muuqda.Muraayadaha wareegsan waxay isticmaalaan qalooc keli ah oo muuqaalkooda ah, taasoo ka dhigaysa mid fudud laakiin ka weyn, gaar ahaan bartamaha muraayadda.
3.Aspheric Advantage
Waxaa laga yaabaa in runta ugu awoodda badan ee ku saabsan asphericity ay tahay in aragtida iyada oo loo marayo muraayadaha aspheric ay ku dhowdahay aragtida dabiiciga ah.Naqshadaynta aspheric waxay u oggolaaneysaa qalloocyada sal-balaadhan in la isticmaalo iyada oo aan waxyeello loo geysan waxqabadka indhaha.Farqiga aasaasiga ah ee u dhexeeya lenska wareegsan iyo muraayadda aspheric ayaa ah in lenska wareegsan uu leeyahay hal qalooc oo u qaabaysan sida kubbadda kolayga.Lenska aspheric ayaa si tartiib tartiib ah u leexanaya, sida kubbadda hoose.Muraayada aspheric waxay yaraynaysaa weyneynta si ay muuqaalka uga dhigto mid dabiici ah iyo dhumucda dhexe ee hoos u dhacda waxay isticmaashaa walxo yar, taasoo keentay miisaan yar.
