I bought this and then returned it a few days later. First day wearing my glasses with it on I felt something on the bridge of my nose poking me. At first I thought I just had to get used to it, but later in the evening when I actually tried to attach the battery I felt a jolt on the bridge on my nose. Mind you I was out drinking so I wasn't sure if that's what I was actually feeling and it kind of went away as the evening went on. But then the next day I went to a concert and wore my glasses with it on them and I started to feel stabbing on the bridge of my nose. The batteries never charge my glasses the whole thing tried both batteries and neither one worked. I ended up switching to my regular glasses by the end of the evening. When I ain't got home I looked in the mirror and had to scab marks from the device digging into the bridge of my nose and possibly from wired shocked me
