Zenni Optical Zennioptical You don't need glasses to see they are unscrupulous San Rafael, California

Beware of ordering your glasses from these people.  When I received my order of two glasses, one for bi-focals, the other for single-vision, it was obvious the prescription was incorrect.
When I called to let them know the glasses were wrong, and to request a return authorization, they told me they would only refund 50% of the price, adding "how could we stay in business if we gave everyone a refund?"
The glasses are made in China.  One can only wonder how huge the markup.  Add the money they keep from prescription errors to their profit margin and you can see how well they are doing.  Maybe right now.
Well, I wonder how long they will stay in business if they keep ripping off their customers.
Won't be long.
