Honestly, these have to be most uncomfortable sunglasses I have ever bought. The rubber nose piece is quite long and digs into the sides of my nose. It's difficult to order glasses online and expect them to fit without trying them on first.  The 1.5 lens part seems to work well, but the plastic appears quite thin and flimsy.  I guess I'll keep them as an emergency pair because I can't wear them for any extended period of time.
