Eye Vibration?

I'm a newbie rider this year, have my own bike, observe all forms of safety, even forsaking the "coolness factor". However, if I go past 45 miles an hour or so, I notice "eye vibration". I wear prescription glasses and would never take them off, but it's certainly not safe. Does anyone else have this problem? I tried using the pinchy things that tighten your glasses to your head, but there is still some movement in my glasses. I really feel unsafe with everything moving around as it does. Would Rx sport glasses help? They're so expensive, would like an easy fix if there is one. Can't believe I would get used to this.
