Here’s what consumers have asked with answers from Zenni Optical staff and previous consumers.
I had no problem with returning my initial pair of glasses. I contacted customer service via online chat and explained my reason for return and I was told I would receive 100% credit that could be applied to my reorder. I followed the return instructions given and kept track via USPS and the transaction went smoothly without any glitches.
Yes, it costs a little more for bifocal lenses. It does not however cost as much as it does in a typical eyeglass office/store.
I had the same experience. Very disappointing. When I called about the problem they questioned the accuracy of my prescription. I was able to return them for a Zenni credit, less shipping costs. Waiting to see if the second pair is better...
Zenni does not repair or send replacement parts. They refused my request for parts.
To my knowledge Zennioptical is an online store and can mail the glasses pretty much anywhere
