I have worn my reading/close work specs on a cord ever since I 1st needed them. I don't like the metal chains, they can get tangled up and caught with necklaces etc. I have to be honest and tell you that it's kinda awkward when the cold weather hits and I wear a snood, artistically wound round my neck (I have to watch a Youtube video of how to do it every flaming time.)
There can be a problem, especially if you wear a handbag crossways over your body, and the strap joins in the fun....but I still recommend wearing specs on a cord :)
