Very fast delivery and excellent customer service - thank you Agnes for your help, very appreciated! I got my first pair with wrong prescription - my own mistake that I put in a "+" instead of "-". So I received a pair of reading glasses rather than a pair of near-sight glasses. Agnes helped me and I got my new pair and just paid for the shipping fee. The only cons is that the lenses are thicker than what I thought. I chose index 1.67 and a smaller adult frame, but the lenses turned out to be still thick. My suggestion is that maybe you can have more smaller frames for selection? Overall a very pleasant purchase experience with this on-line store and will definitely recommend to my friends!
