In my experience there are inevitable issues with the progressive glasses.
One should have different ones for different purposes - paradox :o/
Now, when it's berry-picking time, one issue is accute:
Hiking in the woods you need to carefully look where you put your feet. The lowest part
of the lenses is for reading, so it won't do. You need to walk pressing your chin against your
chest in order to be able to point the 4-6 feet focus area to where you step. Impossible. Also, the path going up and down every yard makes it even harder. When you kneel down to pick berries, it's a little better.
Driving a car and some tasks at job are the only these progressives are fine for.
I still (had them for ten years) can't draw with these progressive glasses on. As Bit described, the drawing gets so skewed it's intolerable. And I have not gotten used to (in many cases) having to move my head instead of my eyes. So, in the woods and gardening, I use cheap +1 or +1.5 glasses, and when drawing, using PC and reading, cheap +2/+2.5 glasses. I have about a dozen of them. For the price of one good pair of progressive glasses you get ten pairs of the cheap, fixed ones. If you get ones with poor lenses, you can afford throwing them away. Of course, you need to have similar sight in both eyes to use the grocery store cheapos.
My wife has used progressives for 40 years, and she still gets seasick/dizzy walking in the woods. And she does have two customized pairs of glasses. She'd need a third pair for the woods.
