Progressive bi-focals have a very small area of full magnification where as line bi-focals give the magnification over the entire area below the line.
The problem often is based on the PD, Pupillary distance.
when you are looking at something far away, your pupils will be a couple of MM's farther apart compared to when you are looking at something up close.
If they did not take BOTH measurements when your glasses were ordered the strongest part of your magnified field may be outside the area where your eyes are focused.
