Been wearing glasses since I was 4. Been using glasses mounted take-a-look mirror for 10 or 12 years. I like it better than handle-bar mounted mirrors. Never tried a helmet mounted mirror, but you might consider the take-a-look glasses mounted mirror. And if you don't wear glasses, consider wearing glasses-style safety glasses and put the take-a-look on them. But they do make handle-bar mount mirrors that clamp or velcro to the bar, and I've seen some that clamp to the brake lever on drop-bars...plenty of options. But even though I haven't used a helmet mount, I'd say I'd prefer that to handlebar mounted mirrors for the helmet-mounted mirror's ability to sweep the background behind you, like the glasses mounted mirrors do.
