Hi Alex,
I like your idea. For now 1 d. is fine for the computer.
For "closer" work, then get a +1.75 diopter - like reading a book.
Make sure to "check" for proper distance (and effectiveness) by "pushing print" to find the "just blur point".
I think that a wise person will combine BOTH exercise AND the wearing of a plus-for-near.
But I add one additional requirement. Patience and persistence. This also includes getting to 20/30 and 20/20 (and stop wearing a minus), and also "refractive checking" - yourself.
This process always aims at your personal confidence and capability - and trust.
You truly trust you self - when you begin to read the 20/20 line, on your own brightly-lit Snellen.
This is just not "medical work", but rather scientific competence - in my judgment.
You are indeed successful.

I mention that I wear only +1D in my case of about 20/25 visual acuity because I spent most of my near vision habits at the computer which I see it at the blur zone of about 70cm with +1D on.
Your +1.75D suggestion I think is also correct because when reading with +1.5D on I need to move away my head from the book a lot. It is in my plans to buy a stronger plus for book reading. Is pupils distance so important factor for plus or can I just buy a cheap pair from a pharmacy store? But on the other hand if I buy them from Zenioptical they also have antireflective coating for future monitor use and can input my pupils distance.
