Are there problems with Nikon's digital eye lenses?

Recently I got eye glasses with Nikon lens- the last I got was in 2007 - however with a slight change in prescription I got the same Nikon lens but one extra new feature digital and I wore them for 2 weeks but having trouble - I went to my eye doctor and she said that some of her clients who have got the digital feature have also complained. Because I have 60 days warranty the place I purchased my glasses say that they can return it and I can get the original Nikon lenses I had. Nikon it seems does not even have a number where consumers can call to question them about their eye lens.
So is any one aware of some having problems? I'm also thinking that if I have to revert back to the original lenses I was going to try Nikon's Max Progressive but am not sure if that will do any better.
I have progressive lens right now but not the max progressive.

This happened to me two. I was also wondering why. I later figured out that its a certain enlargment the eyeglassess make combined with the Nikon Lens iritates the eye.
