Girazi mabhedhi anogadzirwa nekupfura girazi jecha. Zvinoenderana nehukuru, magirazi mabhero anogona kupatsanurwa kuita girazi bead (magirazi mabheji imhando yegirazi mabheji uye anonongedzera kune yakasimba mativi ane chidimbu saizi isingasviki 1 mm) uye magirazi mabheji. Zvinoenderana nekushandiswa, inogona kupatsanurwa kuita inopenya girazi bead, sandblasting girazi mabheji, kukuya girazi mabheji, uye kuzadza girazi mabheji. Pakati pavo, girazi regirazi mabheji rinogona kukamurwa kuita chengetedzo yegirazi mabheji uye skrini yegirazi bead; Zvinoenderana neiyo refractive index, inogona kukamurwa kuita general refractive index uye yakakwirira refractive index girazi mabheji. Iyo general refractive index iri pakati pe1.5-1.64, uye iyo yakakwira refractive index inowanzoita 1.8-2.2. Tichifunga kuti iyo yakanyatsokodzera kufungidzira igirazi mabheji ane refractive index ye1.93, iyi refractive index inogona kudzorwa zvinogutsa kudzokera kumaranzi akafanana, saka iyo yakakwirira iyo refractive index haisi iyo yakanyanya kuratidzwa.
