My understanding of Perfect Vue ...
TruVue tried to make Museum glass. They succeeded, but with a lot of blemish scrap. If you acid etch the back, you can't see the blemish and they can say it reflects less. And, they can effectively sell their scrap hence ... Perfect Vue. Kind of a half-breed between Reflection Control and Museum.
I find it looks pretty good if not viewed near Museum. But, I think for the money I'd just as soon sell up to the Museum, or "down" to the Reflection Control.
Another piece of data (at least around here) M******'s "highest end" glass is Perfect Vue and they seem to sell a LOT of it. They don't (at least the last time I checked) offer Museum.
