    I'm 58 and work in a small workshop making hand made furniture. Some of my work is close up detail work, some is at arms length such as working at a bench or when using machinery and when working on larger pieces of furniture I need to see up to about 3m away.

    For the past 8 years I've been wearing a pair of varifocals, they are far from perfect but I have got used to their idiosyncrasies and I have stuck with them as they have given me moderately clear vision for all the tasks I do in the workshop.

    I had my eyes tested 2 years ago and my prescription had altered so I bought a replacement pair of varifocals. I couldn't get used to them, the intermediate corridor was very narrow and the sway and distortion was too large for my type of work. I returned them and have stuck with my old varifocals, a pair of long distance and a pair of reading glasses since then.

    It's coming up to that time again to have my eyes tested. Varifocals are not going to be an option so to adequately cover the range from reading distance to about 3m away I'm looking into the possibility of a pair of intermediate/near vision bifocals.

    My prescription from 2 years ago was:

    SPH: R +1.25 L+1.25
    CYL: R -0.75 L -1.00
    AXIS: R 3.0 L 22.5
    ADD: R +2.0 L +2.0

    As I understand it the ADD part of the prescription relates to the reading part of the prescription. If I were to have a prescription for intermediate glasses this ADD figure would be between 0 and +2.0, with the actual ADD number dictated by the Optician dependant on the distance I say that I need to focus on.

    Ideally I would like good vision from reading up to about 2.5m-3.0m without anything going out of focus (too much). So what sort of ADD number would be best for my application?

    Thanks for any help.
