I really love these neck hanging glasses. this is a genius idea. I have 20 other pairs of readers, but these are the only ones I wear, because they are around my neck, I don't have to go look for them!! I was actually getting thin hair on the sides of my head from always putting my readers up on my head. well When I started wearing these neck hangers, I no longer have to do that, and my hair is still intact. I am so glad I found these. this is the 3rd pair I've gotten. They're stylish and durable and just what I needed and wanted. excellent.
