I don't seem to experience the vibration distortion with mirrors mounted to the arm of my glasses. My guess is my Halo headband holds them tight against my skull.
However, keeping the mirror secure to the arm can be challenging. I've broken several of [MENTION=418370]canklecat[/MENTION] 's example above. I've had them come off while riding and splatter across the road. Or the arms break due to the thickness of the glasses arm. Finally, I produced a sewn-on leather band to secure the mirror to the arm.
The leather band is laced to the arm, like shoelaces.
One of the plastic retaining arms had broken on the above mirror.
The mirror can fold inside the arms for storage in the case.
Like my post above, I have to ask why? Why do we cyclist have to jump through such hoops to have a good mirror that works? Yes, for eyeglasses, there are a lot of standards. But there are also several big brands with huge marketing. Relatively few helmet makers. And how many cyclists who could benefit from really good mirrors who don't have our time or inclination?
