The clip has small metal eyelets with rubber tips. One of the rubber tips came off, perhaps due to the fact that they were persistently removed and put on. I wore them like this for a while before realizing my polycarbonate lens had a scratchy mark. I still liked them so much that I bought an extra set as the darker pair are very close to my glasses, but maybe this time I'll remove all the tips and put a drop of superglue in them. See it and improve the tips' ability to stick to steel levers.
