Anyone use bifocals or trifocals?

@GECKODEV an update on the glasses: The “computer” glasses, which are bifocals with Intermediate as the main lens and Close as the lower inset lens continue to be excellent at the bench. I may end up getting single focus glasses for the Close prescription for when there are long extended periods of close-up work, like carving, to reduce neck strain. The bigger message, though, is that gave up on the other pair of bifocals, which had Far for the main lens and Close for the lower inset lens. This makes sense I suppose, but it didn’t work for me. The Far let me see down the road for driving, but I couldn’t see the instrument panel. It was too far away for the Close prescription and too near for the Far. We remade the glasses to have Far for the main lens and Intermediate (like the upper part of the computer/bench glasses” ) for the lower inset lens. Perfect!!! Now, I can see the dash. Also, they are fine for most reading, e.g., at lap distance or standing reading a label. So, I can do everything with them except close fine work, for which I just put on the other glasses.
