Visor yagenewe kwirinda urumuri rw'izuba no gukumira ingaruka z'izuba. Bamwe barashobora guhuzwa inyuma, kugirango uhindure izuba rirenze amaso, birinda kubaho kwabaye, kandi ufite ingaruka nziza zo gukonjesha. Irashobora gukoreshwa mu nzu, nka virusi ya mumodoka: Visir nayo ituma bigora urumuri rw'izuba mu modoka, bifite ingaruka nziza zo gukonjesha, ariko nanone zirashobora kurinda ikibaho, intebe y'uruhu. Sunshades irashobora kandi gukoreshwa hanze.
Gukoresha hanze
Radiyo yemewe ya curvature (R) igomba kurenza inshuro 180 z'ubugari bw'isahani.
Urugero: Kurugero, niba ikibaho cya 3mmpC cyakoreshejwe hanze, radiyo ya kaburimbo ya curvature igomba kuba 3mmm × 180 × 180 = 54Cm. Kubwibyo, Radius yashizweho ya curvature igomba kuba byibuze 54cm. Nyamuneka reba kumeza ya radiyo ntarengwa yo kunama.
Gukoresha mu nzu
Radiyo yemewe ya curvature (R) igomba kuba inshuro zirenga 150 z'ubugari bwisahani.
