I hate to admit it, but I'm going blind. I now must wear my eye glasses to watch TV and see anything more than ten feet away. The trouble is, my glasses don't help up close. So, I'm constantly putting my glasses on top of my head where the rest ever so precariously. One wrong move and they fall to the floor. I've scratched lenses on all my glasses because of this bad habit. I finally got the bright idea to order one on these eyewear retainers. So, you've got eye glasses hanging from your neck much of the time. It could be worse. (Why didn't I think of this before I damaged all my lenses?)
