No fewer than 11 frames in a variety of styles with progressive lenses over the last year and none of the optics are satisfactory. The Zenni China experience went from economical to expensive in short order, over $600.00 USD and I still don't have one good pair of glasses. The Anti-Reflective coatings they use are sensitive to anything but cool water with mild soap, even high quality optical cleaner heavily diluted with water will in time break down the AR coating leaving thousands of micro fractures on the lens that cause flaring and a general smudged appearance, exactly what I was trying to avoid when ordering AR coating!?
Zenni has two options for pupillary distance: Single PD and Dual PD, but no entry for Near PD, be very aware of this when ordering progressive lenses. Zenni is like stopping into the Quicky Lube when what you really need is a professional tune-up.
I've since ordered a "Live Fitting" with Zeiss Schott Glass, yes it's expensive but so were 11 pair of "discount" Zenni lenses. Zeiss glass is superior optical technology that China has not yet been able to steal and ruin
