You can get a separate intermediate distance pair specifically for computer use. If you're -2.25 then something like -1.25 would put optical infinity at 31 inches away allowing your eyes to be completely relaxed. I've got close to the same prescription and just prefer to keep my screen at 24" and increase the font size a bit, and I can see that just fine most days. I'm not sure if my brain has learned to deconvolve better, but around -2 is a sweet spot where you can definitely get away with not needing glasses at all for computer work if you try, considering that you're uncorrected plane is at 20 inches.
