I-visor yenzelwe ukuphepha ukukhanya kwelanga kunye nokuthintela impembelelo yelanga. Eminye isenokushukunyiswa emva naphambili, ukuze ilungelelanise ukukhanya kwelanga emehlweni, ukuphepha ukwenzeka kweengozi, kwaye ibe nesiphumo esingcono sokupholisa. Inokusetyenziswa ngaphakathi, njenge-visor yemoto: i-visor yenza kube nzima ukwala ukukhanya kwelanga kwimoto, inesiphumo esingcono sokupholisa, kodwa inokukhusela ideshibhodi, isihlalo sesikhumba. I-sunshades ingasetyenziselwa ngaphandle.
Ukusetyenziswa kwangaphandle
I-radius evumelekileyo ye-curvature (R) kufuneka ibe ngaphezu kwamaxesha angama-180 ubukhulu beplate.
Umzekelo: Umzekelo, ukuba ibhodi ye-3mmPC isetyenziswe ngaphandle, i-radius yayo ye-curvature kufuneka ibe yi-3mm×180=540mm=54cm. Ke ngoko, iradiyasi eyiliweyo yegophe kufuneka ibe yi-54cm ubuncinci. Nceda ujonge kwitheyibhile yerediyasi egobayo.
