Last week I received my first pair of "lineless" bifocals.  After a 
week I went back to have the fit adjusted and aligned for better
far and medium vision - much better!  However, during that week I
noticed a lot of Pulfrich effect while watching tv, so I assume that
one lens was underperforming, making that eye work harder and giving
the effect.

It's gone now.
