The issue I think (as a glasses wearer) a lot of wearable eyewear has is that it generally assumes the person won’t already be wearing glasses. I remember Google eventually fixing this, by letting glasses wearers buy prescription lenses with their Glass. BUT not as a separate attachment for their current, existing glasses. Also how many people really want to walk around in public, looking like a borg?

So good idea. 👍 Bad execution. 👎
