Thanks for clarifying that. Very helpful to know it's not supposed to work this way.

I got the prescription here in Canada, but the glasses were made by Zenni in China, so there is a bit of a disconnect. Zenni will refund me half the value, but I am going to ask them for the full amount now I know they are not supposed to work that way at all. They checked a scan of prescription and they say they filled it right (ie I entered it right in the computer.) Any thoughts, Christina?
