Hi. I'm online and happy to answer your question today.
This is not related to your PVD. Most likely it has to do with your progressive lenses. As you might know these type of glasses have a zone of "warped" material where the power of the progressive bifocal is formed.
Here is an excellent article on the topic:
What is most likely happening is that you are looking through a small edge of the normally "warped" part of the lens due to a change in the fit from the sore on your nose and, possibly, a slight distortion in the fit of the frame.
This is nothing to be concerned about. I suggest you see your optician who can check how the glasses fit on your face, where you are looking through the lens and set everything back the way it should be.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
