Visor yagenewe kwirinda urumuri rw'izuba no kwirinda ingaruka z'izuba. Bimwe birashobora kwimurwa inyuma, kugirango uhindure izuba ku jisho, wirinde ko habaho impanuka, kandi bigira ingaruka nziza yo gukonja. Irashobora gukoreshwa mu nzu, nk'iyerekanwa ry'imodoka: visor nayo ituma bigora kwerekeza urumuri rw'izuba mumodoka, bigira ingaruka nziza yo gukonjesha, ariko kandi birashobora kurinda ikibaho, intebe y'uruhu. Izuba rirashobora kandi gukoreshwa hanze.

Iradiyo yemewe ya curvature (R) igomba kuba inshuro zirenga 180 ubugari bwisahani.
Urugero: Kurugero, niba ikibaho cya 3mmPC gikoreshwa hanze, radiyo yacyo yo kugabanuka igomba kuba 3mm × 180 = 540mm = 54cm. Kubwibyo, radiyo yagenewe kugabanuka igomba kuba byibura 54cm. Nyamuneka reba imbonerahamwe ya radiyo ntarengwa.
