The first pair of glasses I ordered from 3D vision took 30 days to complete. An upgrade to the transition lenses that I had ordered could not be delivered. The second pair I ordered from them took 32 days. They could not do transition lenses at all for some reason. I have little magnets in my field of vision for clip on sunglasses that are so dark I can't read my speedometer. They cannot deliver what is ordered. The itemized receipt does not show my original order. Once is a mistake, twice is a habit. The staff is not trained. Be sure to get an itemized list of what you have ordered before you pay for it. If you wait till you get your glasses, the receipt will reflect what you get not what you ordered. And be patient with them, you may wait a month for you glasses like I did twice. This was a $830 lesson for me. $500 of it out of my pocket. Be careful with them if you choose to go there.
