I've worn glasses and ridden my entire adult life. I prefer full face, have used various brands and generations of Shoei, Scorpion, Bell, Arai ...(others I can't even remember) from 70's to current.
Glasses off before putting helmet on, off again prior to helmet removal. Its always a necessary PIA...but I've never once brought my helmet in to optometrist to attempt test fitting of frames. But never had a major issue thereafter, either.
Hey, why not bring your helmet in? Give a try.
PS...thin earpieces able to slide in/out between the helmet padding and your temples may be in your best interests. Something to be aware of and experiment with. Maybe the opto will offer some ideas, suggestions or alternatives on frames.
good luck with it!
