In my opinion, glasses have a sweet spot in the glass.
I wear trifocals. I have the lines that separate the three.
I know that just above the top line is the sweet spot. This is more important to me when manual focus is used.
Your glasses require correct adjustment so that the lines are even with your pupils (not just face). Actually, I need the correct adjustment for close up stuff, like reading.
Hope this helps!!

I'll tell you what DOESN'T work for me.....no line bi-focals !! I didn't like the line so I spent a couple hundred on NO-LINE glasses......can't really look towards the side, I have to be looking through them straight on.......terrible !!
