I had vai-focal lenses for some years, and whilst my near & distance prescription was not too different, I coped. It gave me what I needed. However a couple of years ago it was decided that I needed more strength for reading. From then on I couldn't cope with var-focal lenses - I tend to move my eyes to focus and I could not get used to moving my head to find the small focal point for what I was looking at - much as RCR describes.
Bi-focal lenses are fine, but not ideal; it's harder to draw (for instance) and also read a newspaper - probably one of the drawbacks of growing old(er) - having one eye described as 'lazy' doesn't help my poor brain to interpret what I'm looking at .... I tend to have to sit too close to a PC screen than I ought to ... looking through the 'reading' part of the lenses.....
With time, it ought to get better RCR, mine cost £600 (vari) - so I expect that is a fraction of your cost ! - I'm surprised how expensive bi-focals are too ...
