I see there are some pretty terrible reviews on here and granted things go wrong especially when you're ordering something like glasses. But I have to say after having ordered three sets of glasses through them I think I can give you a pretty fair assessment of at least my experience.
The first time I ordered glasses through glasses USA must have been approximately 6 years ago. Everything went fine no particular problems. The hard part is just being patient and waiting to get the glasses but they came and they were okay.
The next set of glasses were okay but there was something about one pair that just never seemed quite right the way I could see out of them. But it was a pretty minor problem everything considered and I kept them.
My most recent glasses which I just received a few days ago well...... That's a different story. I ordered glasses and then promptly got a message back that said the frames I picked were unavailable. Okay so I picked another frame. Then nothing happened. But I called in and the customer service person was nice enough but I ended up canceling those and was a little perturbed.
After a couple weeks or so I got a good offer for buy one get one free so I went back on the site and picked out some glasses and some sunglasses. This time the service was excellent and the speed with which they got the glasses done and shipped was actually ahead of time and I actually received them a day before the scheduled delivery date. So I thought that was fantastic!
So now I have my glasses and they are absolutely all that I had hoped for and maybe a little more. And after reading these really bad reviews I thought I would go ahead and put my two cents worth in here.
All I can say is anytime you order online to begin with you need to look at reviews on several different sites for that same company. Read the good reviews, the indifferent reviews, and the bad reviews. Then you've got to just stop and think about what you read and what makes the most sense. And this is for any company out there.
Glassesusa has been around a while and they've sold a lot of glasses. I originally started buying my glasses online after a Dave Ramsey review of Zenni optical. I didn't really have any problem getting glasses from them it's just that they were cheap in price and of course they were cheap in quality. I think Glassesusa does a pretty good job. So you just have to use your own judgment and give them a shot.
