My friend is an eye surgeon/opthalmologist, and I had him check out my zenni glasses and he assured me that they were fine. We have 4 prescriptions here, including a son who throws and breaks his glasses regularly. I just ordered him 2 new pairs and one pair of progressives for me for 78 dollars (it was the buy 2 get one free sale). I would suggest going to one of the stores mentioned to try on glasses to see what looks best on you, then order a trial pair from zenni. At worse, you'll have a backup pair in case something breaks. We have had a great experience using zennioptical.
