Utomoni ndi hydrocarbon (hydrocarbon) exudate ku zomera zosiyanasiyana, makamaka conifers. Chifukwa cha kapangidwe kake kapadera ka mankhwala ndipo angagwiritsidwe ntchito ngati utoto wa latex ndi zomatira zimayamikiridwa. Ndi chisakanizo cha mamolekyu apamwamba kwambiri, choncho amakhala ndi malo osungunuka osiyanasiyana. Ma resins amatha kugawidwa kukhala ma resin achilengedwe ndi ma resins opangira. Pali mitundu yambiri ya utomoni, womwe umagwiritsidwa ntchito kwambiri m'makampani opepuka komanso mafakitale olemera, m'moyo watsiku ndi tsiku utha kuwonekanso, monga pulasitiki, magalasi a utomoni, utoto ndi zina zotero. Lens ya resin ndi mandala pambuyo pokonza mankhwala ndi kupukuta ndi utomoni ngati zopangira.

1.56 ndiye index yowonekera ya mandala

Kukwera kwa refractive index ya mandala, kumachepetsanso disolo la digiri yomweyo. Anthu ambiri amagwiritsa ntchito magalasi okhala ndi index ya refractive ya 1.56. Ngati digiriyo ndi yokwera kwambiri, ma lens okhala ndi index of refractive ya 1.56 adzakhala wandiweyani kwambiri, choncho tiyenera kusankha magalasi okhala ndi index yayikulu yowonera. Kupaka ndi kupaka mandala ndi zinthu zosanjikiza zomwe zimakhala ndi ntchito zosiyanasiyana. ena

Anti-ultraviolet filimu, ena akhoza kuimba zotsatira za kuonjezera transmittance wa mandala, ndi bwino magalasi.

Kawirikawiri, posankha magalasi, tikulimbikitsidwa kuti chiwerengero cha refractive chisakhale chokwera kwambiri kapena chochepa kwambiri, chifukwa magalasi omwe ali ndi index yosayenera ya refractive adzawonjezera kulemetsa kwa maso a odwala. Magalasi okhala ndi 1.56 ali ndi index yotsika yowoneka bwino, yomwe nthawi zambiri imakhala yoyenera kwa odwala omwe ali ndi myopia yochepa kapena myopia yapakati. Nthawi zambiri amalangizidwa kuti anthu omwe ali ndi myopia yocheperako komanso yotsika asankhe magalasi okhala ndi refractive index pakati pa 1.50 ndi 1.60.

Refractive index ikugwirizana ndi makulidwe owonda a mandala, koma posankha mandala, simuyenera kungoyang'ana index ya refractive, komanso kuyerekeza mphamvu yokoka ya mandala, kutulutsa kuwala, kukana kwa UV ndi zinthu zina kuti muganizire mozama.
