    Could someone tell me how the reading portion of my new prescription
    compares with the old one in terms of strength?

    I had the new prescription made up and was totally unable to read with
    the lower portion of the bifocals. Yet I can still read quite well
    with the old ones.

    I have been given conflicting stories and am unsure whether the
    problem lies with the prescription or the lens manufacturer.

    The two prescriptions can be view here:

    Many thanks.

    there is very little difference in the reading power of your old and
    new bifocals. the small difference that exists is in the left eye.
    how do you think your distance vision is in your new glasses?
    do you feel like you have to hold your reading material further or
    nearer to see it better with your new glasses?
    is your bifocal height different in your new glasses?

    Thanks for your reply. The distance part of the new glasses seems
    fine, but the reading portion is blurred at any distance. Since you
    confirm that the prescription for the lower part of the bifocals is
    very close to my old glasses, I can only assume that there has been a
    manufacturing error (one optician at the store thought this was the
    case, the other - more senior - optician said he had tested the
    glasses and they matched the prescription).

    As far as I can tell, the bifocal height is the same in both pairs.

    My old glasses date from 2001.

    These new glasses resulted from a reassessment of my prescription by
    the ophthalmologist. His first new prescription, filled by the same
    opticians a month earlier, had a very aggressive reading portion,
    which resulted in my having to hold reading material at a very precise
    and close (and for me unnatural) position. That prescription was very
    likely based solely on my age.

    My plan is to accept a refund on the glasses from the opticians and
    then to get a new prescription from an optometrist after asking
    friends for their recommendations. I have little desire to go back to
    the ophthalmologist or the same opticians. Meanwhile I'll continue
    with the 2001 pair which are fine for reading but slightly too weak
    for distance.

    Again, very many thanks for your input and for your patience in
    reading this rather confusing tale of woe.

    i suggest that you take both pairs of glasses, and both prescriptions,
    into the optometrist when you get your exam. tell him precisely about
    your troubles and what you would like your glasses to be able to do.
    good luck!

    Thanks for your reply. As a layman it's a little hard for me to grasp
    the technical language, but I will take a copy of it to the opticians
    when I have a fresh prescription and I'm sure it will be helpful. It
    will certainly enable me to ask some relevant questions.

    I really appreciate your advice and assistance.
