I recently purchased a progressive pair of Barton Perreira glasses with X design lenses. And wow! I was very impressed how easily I was able to adapt to progressive lenses. I have always had trouble adapting to new progressive glasses. The sales person was patient and spent the time to explain everything I needed to know. She recommended numerous frames that suited me, which was great to have so many options. I highly recommend this place for their choice of glasses, their knowledge, attention to detail and patience!
