The thing is that with progressive bifocals, and the right size lense, this is rarely an issue, as you choose the focus you need by simply moving your eyes and head. When setup properly I rarely need to move my head at all for normal day-to-day stuff, as we naturally put what we’re viewing in the center of our vision.
For example, when looking far, we tend to look upward more, so naturally use the upper portion of a lense. When on a computer or reading, we tend to look downward. Driving is a great example, we look forward and up while driving, down to see the dash, and progressives cover that with no problem.
The only time I run into “problems” is when doing really close work for an extended period, like stuff inches from my face. But for those times, I just switch to readers only while I’m doing that work. These glasses could maybe work there.
