The magic words I think are “occupational multifocals”, which have a small area at the top for distance vision and the remaining 75% set for whatever your occupation is. You need to be very specific on the distance setting

Yes. This is the better solution.

Some expensive lenses like Zeiss, Varilux, and Hoya make you an extra pair when you by one. I tought that the extra pair must be equal the first one, but it isn't necessary. I could have asked for a general one and one with a greater area for medium distance.
