They are a lovely fit and don't pinch the bridge of my wide nose.
My only criticism is I wish they were a few shades darker!
they fit well, and I use them because they are a good price, and I have lost many good pairs in the past so am reluctant to spend on this item. There does seem to be a design issue with them as the bridge on the nose is not very strong or flexible, and if there is any pressure applied can break at this weak point. As they are not expensive, I just keep a spare pair, but be prepared they are not very durable
What more can I say?!
Simple and effective; very good value.
