The new Scott Split OTG goggles or the 100% Accuri OTG googles are two very good OTG googles. I use Scott 87 googles from years ago. I actually bought them at Iron Pony when they were on a close out sale for about $5 each years ago. I still have one pair in the box for a backup.
No I don't notice my glasses bouncing at all. But, there are precautions you must use other than the average rider. Your glasses will fog up before your googles, so you gotta have a defog towel or wipe for both sides of your glasses and the insides of the googles. Also, if you ride in the rain you'll need lots of tearoffs, or roll offs, as you don't want to take the googles off. Won't take much for the glasses to get muddy or water on them and you can't take them off.
I've used contacts too, they work well too, but I always forget to put them in before I leave because I usually wear glasses. Never had a problem with contacts, but always bring everything with you that you need to take them out and clean them if you have too, and an extra set, and your glasses as backups.
