These glasses are wide and slip off as soon as I put them on. Most women's glasses fit me even though I have a smaller head. I was hoping to tighten them up and noticing that they came with a few extra screws and a tiny repair kit, I removed one screw to see if I could replace it with something else to tighten it up more tightly make (it was not mentioned in this article in the instructions so I had to guess that any additional parts would fit any glasses of this brand). After I removed the screw, it was physically impossible to insert any size screw, including the original screw. My husband and I spent over an hour trying it together. If there was a way to make the glasses tighter on my head it might be fine, but I haven't had a chance to try them. They feel solid compared to other cheaper readers.
