Magirazi ezuva anovharira kupenya kusingagadzikane uku uchidzivirira maziso ako kubva pamwaranzi yeUV.Zvese izvi zvinogoneka nekuda kwesimbi poda mafirita ayo "sarudza" mwenje painorova.Magirazi ane mavara anogona kusarudza mamwe mabhendi ewavelength anoumba mwaranzi yezuva nekuti anoshandisa hupfu hwakatsetseka hwesimbi (simbi, mhangura, nickel, nezvimwewo).Muchokwadi, kana mwenje ukarova lenzi, inodzikiswa zvichienderana nemaitiro anonzi "anoparadza kupindira."
Ndokunge, kana mamwe mafungu echiedza (munyaya iyi, UV-A, UV-B, uye dzimwe nguva infrared) achipfuura nepakati pelens, vanodzima mumwe nemumwe kunze kwemukati me lens, kuziso.Kupindirana kwemasaisai emwenje haisi tsaona: nhongonya dzeimwe wave uye zvigero zvemasaisai ari padyo zvinodzima.
Chiitiko chekuvhiringidza kunoparadza kunoenderana nerefractive index ye lens (kureva, dhigirii iyo mwenje wemwenje unotsauka kana ichipfuura nemuzvinhu zvakasiyana mumhepo), uye zvakare zvinoenderana nehupamhi hwema lens.Kazhinji kutaura, ukobvu hwelenzi hauchinje zvakanyanya, nepo refractive index yelens inosiyana zvichienderana nemusiyano wemakemikari ekuumbwa, uye magirazi ezuva haafanirwe kuratidzwa kune yakananga zuva.
