I used a voucher to order a set of progressive lenses for myself of a brand I've recently sold but not yet worn. They came in today, and to my dismay the vision was horrible!! I literally had to optician myself and try to troubleshoot. I tried everything from adjustments to panto, covering one eye and then the other. I tried to walk around and forget about them. As my frustration mounted, I started to feel a cold chill , what if I had been selling a brand of lenses that is inferior? By 15 minutes in I had a terrible headache and I still couldn't find a single part of either lens that I could read with, no matter how I moved my head or glasses. I went back and stared at the invoice for the third time trying to see it with fresh eyes (by this time I was back in my regular progressives). I then realized that I had flipped the add powers when I ordered them, my od is +3.00, my os is +1.50. No wonder I couldn't see!
