I ordered some glasses last month, and they came in wrong. Too much trapazoid stuff happening, so they glasses folks kindly reground them to the same exact result. So, I then went in and they rechecked my eyes and everything came out the same. The trapazoid stuff was simply because of my progressive lenses.
I hadn't ordered progressive lenses. Problem found. My glasses are far too small for progressives, unless you LIKE getting both distance and reading at the exact same time. I don't like that motion sickness feeling, and I don't get motion sickness. Anyhow, my glasses should be in in about a week.
