I have had a Mar 10 Lexan shield for 15 years and used it extensively with wipers. It did get a few scratches over the years but not from the wipers.
I replaced it after I had a accident and that windshield saved my life. A tree branch that scratched the shield I am sure would have gone through a glass one.
Anyway, this time around I was a cheap ass and did not get the MAR10 and the Lexan (plain) scratched the first time I used the wipers!!
So with the scratch resistant MAR10 .........go for it!!!!
