The suggestion of metal frames is a good one. I’ve been wearing Shoei helmets sense the mid 1990s. I’ve warn eye glasses sense I was 3 years old, 63 years. The thin metal bows works really well especially if you have com speakers. The first time I had to add bifocals I pushed off putting them in my prescription sunglasses. A rather expensive mistake. Go ahead and try to look over the top of your glasses in the tiny slit of space between the top of the glasses and the opening edge of the helmet. You will show your age when you have to shut down the bike and remove your glasses to read a map. When you have 15 bikes waiting on the ride leader.
