Used to be great.  Now garbage.
[[VIDEOID:4a777f8648496e3c4fa9e063cf8602a7]] I've bought this a few years ago.  Was as clear as regular bifocals.  I ordered one 6 weeks ago ... blurry patches (see video). So they sent me another at no charge.  Again, blurry patches ... I can't read with these.  Why is it after a company is successful their quality control goes to the dogs?  Really, this is something they can and should be easily checking on every product with an automatic optical test ... no humans even needed.  As an engineer I could design a system that would do that automatically, any decent engineer could.
