I wear glasses and I have a 2017 GT w HUD, I've found that my existing polarized prescription sunglasses make the HUD nearly invisible. Looking around for some non-polarized clip-ons was frustrating because almost everything is polarized. But I found this site that has a wide range of non-polarized wear-over/clip-on/flip-up and regular sunglasses. They seems to be pretty reasonably priced too.
Just thought I'd share it if anyone is interested: https://sunglassrage.com/
