Most progressives are problems. Varilux is better these days but still blurred compared to Zeiss. Zeiss is far better for only slightly more money. I find the best solution is Zeiss on a frame that has a nosepiece that moves the lenses higher for reading and close work. Such frames started in Austrailia a few years ago but are now in the US. You may also like what they call a "Double D." These have another bifocal inverted and set at the 12 oclock position so that commercial pilots and focus on overhead switch panels. Also be aware that fast service labs too frequently mess up your prescription; even though the industry "allowable" error is plus/minus .125 diopters. Frankly .125d is sloppy enough to be irritating; so tell them to get it right on your prescription and then check it there and by an outside firm when it arrives. I deal with a quality medical provider in a good area and they still miss the prescription about 50% and have twice tried to sneak me Varilux. BTW plastic is not a clear as glass, and the problem with your exact request is that such a blank on which to grind may not be in the US directory. Let us know if you find a source.
