Priceless, we are chastised for not ass-uming that they were in fact, prescription lenses.

Just for my own entertainment, I tried on my Decots earlier today. Head down some, slight right tip down and back, and sure enough there's a sharper area where the birds might be. When I ordered them, the helpful person on the phone explained what they did, but I didn't take it all in. Certainly, in-person would be ideal if the right tech were present, but over the phone and through the mail was very satisfactory, in terms of results.
