However, the glass holder in the middle, above the nose bridge is far too easy and, unfortunately, no good at all. I bought these glasses a few weeks ago and had it after a few jogging and cycling back again. While jogging, it happened to me several times that when straighten the glasses, the glass broke out of the socket and I both held in his hand - the training on time very impractical. Once me the glass is even fell down while running, without that I noticed at once (I have the glasses with clear prescription glasses) and I was lucky that it was not broken.
With a drop of superglue is here certainly done a lot, but then you can no longer change the glasses (from clear to tinted).
