i have waxys in glass exo terra 18x18x24, it works well, but I would love the cage with screen sides and glass front for better viewingbut such a thing doesn't exist. they need airflow and low humidity, I've never heard of nose rubbing injuries, but they don't really rub their noses, they are slow and moving like monkeys.
the only problem with screen cages is keeping temps, but if you get basking lamp, they will choose what temp they like better, if too cold will move higher, closer to the lamp.
