The Zenni - China experience went from economical to expensive in short order. After purchasing from Zenni, 11 frames with progressive lenses in one years time, I still don't have a single satisfactory pair of eyeglasses. Inferior AR coatings that fail and break up into thousands of micro-fractures resulting in flaring and smudged vision, blurry focusing zones, shifting my eyes to the upper corners of the lenses because that's where the clearest long distance vision is best on most every pair i've ordered — not anywhere near the center where it should be, the freaking corners, can you imagine!! A word on returns and reordering with store credit: Zenni is in no hurry to refill these orders and get them to the U.S.
