I have trifocals and I can see my keys fine with the bottom part of the lens. I use the middle distance for the monitor, and my far vision not at all when on computer.
New glasses might help alot. At his age, I had trifocals for almost 10 years already!
You can have bifocals made with only close and mid range also.
I use those for art work and reading. I use the trifocals when I work, or shop or drive or go out etc.
