My optometrist set the adjustable lenses to what he thought was in the right ballpark and then had me read the chart at my requested distance for the computers lenses. A few adjustments, and done. They're perfect! Bonus: text is a bit bigger now, and I can read smaller fonts than I could before getting computer glasses.
The downside of this is that I now find it very difficult to read computer screens and my phone while wearing my distance lenses. The practice of holding things further away to be able to read them always was, I suppose, inevitable.

You should ask a qualified or licensed optometrist or optician or whatever it's called wherever you live.
AIUI:
- you don't adjust CYL
- The amount you add is roughly 0.75, plus an extra 0.05 for each year above 40yo.
For example, at age 50:
Add = 0.75 + 0.05 × (50 − 40) = 0.75 + 0.5 = 1.25
So let's say that this person's regular glasses are -3.25 in each eye. Their computer glasses would be -2.00 in each eye.
Don't trust random strangers on the internet!
