Okokuqala, kufunxa ubushushu obuvela kwimitha yelanga.Umzekelo, iglasi edadayo eyi-6mm ecacileyo, i-diathermancy iyonke phantsi kokukhanya kwelanga yi-84%.Kodwa kwiimeko ezifanayo, yi-60% yeglasi enemibala.Iglasi enemibala enobunzima obahlukeneyo kunye nombala owahlukileyo, iya kutsala ubushushu obahlukileyo kwimitha yelanga.
Okwesibini, Funxa ukukhanya okubonakalayo kwelanga.Iglasi enemibala inokwenza buthathaka amandla okukhanya kwelanga, ibe nefuthe le-anti-vertigo.
Okwesithathu, ukuba sobala, kunokufunxa imitha ye-ultraviolet, ukukhusela abantu.
