>         I have a few options to offer for your student. 

    One consideration would be corrective surgery that can now correct
    astigmatisim but would not help with her magnification needs. I use
    Zeiss Lenses for my general work during the workday. These are the
    equivelent of a # 7 optivisor or slightly better. With a wonderful
    working distance of 11 " and are very lightweight. They correct both
    my far sighted issues and need for reading magnification so nothing
    else needed. I buy these from Miller Optical in Texas and have been
    very happy with them.I believe they are also available in a lighter
    power. 

    I also use surgical loupes from Design for vision in N.Y. These are
    larger and heavier telescopes and I wear them for fine detail work
    only but they also contain my needed script ( optional ), and the
    combination of the two answers all of my needs.They also make the
    smaller lenes  AT  lower magnification with or without script included..
    It also seems to help to keep the " Pop " in the greater
    magnification as I noticed a few years back that if I wore the
    stronger magnification all day, my eyes would over time seem to
    adjust and I would loose some of the power somehow. I can't explain
    this medically but this is what I found happened. 

    This is another area where our trade falls far short of
    professional. To think that for the majority of the trade the typical
    answer to this need is plastic lenes with a terrible working distance
    and fixed pupilariy distance, as if all our eyes are the same
    distance apart.This creates terrible strain on our eyes and over the
    course of time I believe  bigger trouble, and this in a trade where
    our healthy vision is so critical . Sorry to ramble a bit but "your
    eyes" are worth it. Peace Karl
