Hi all.

I've tested four or five sets of progressive lenses, the latest being touted as "premium" and some others as "wide field..." and found that the reading zone is mostly useless.

You have a few millimeters of clear vision in the very middle, but any deviation outside that results in a double image. You can't even read one page of a paperback book with these.

Yet bifocals can cross the entire frame.

What is the problem here? Why can't we retain the wide reading zone and simply feather it into the mid range and then again into the upper range? The current status quo is a pathetic and degraded visual experience for the customer.
