I made a glasses with the focus optimized for 1.5m. A lot easier on my eyes for working than my progressive lenses.

How did you go about that? Can you just take your prescription someplace and have them made?

Tell your optometrist you want that, and they'll write the prescription.

Last I went, they wrote me two different prescriptions: one with an up-close focal point for books/screen work, and a second one with the focal point further out for driving.

Yes. You can have reading lenses or lenses for medium distance. Measure the distance from your seat to the screen. Get a max, minimum and most common distance in your different seating positions.

Not OP but look into "computer glasses". Usually they're optimized for distances a bit closer than 1.5 meters, but I'm sure that can be changed.

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.

I used to work in the optical industry, that's not what computer glasses are, they are just blue blocker lenses.

Any lens can be customized for desired focal length, including distance, intermediate (e.g. computer) or closeup/reading.

Right. It's an industry term though and doesn't have anything to do with focal length.

Consumers develop their own interpretations and usage of industry terms used in marketing to consumers.
