Screen cages are not a must for chameleons. I have kept chameleon's in glass cages for most of the years I've kept them...and my veiled females, for instance usually live to be 6 and more often than not 7 years old. The males live even longer. There is no one kind of caging that is the only way to keep them...there are pluses and minuses for each type. If you don't do it right, with screen cages, you may have trouble keeping the humidity up all year round and temperatures high enough in the winter. With glass, you may have standing water issues and trouble with temperatures in the summer time.
Also, in my 25+ years of experience very few of the chameleons I have kept have had any reaction to a reflection in the glass.
Just my opinion.
