    Hi,

    I am looking for a recommendations for progressive lenses (by brand and
    model)

    By day, I am either reading from paper or computer screen (about 50/50)

    I am also a pilot, which involves near vision (For charts),
    intermediate vision (for instruments) and distant vision. It also calls
    for reasonably good peripheral vision (especially for landing).

    I am hoping that one or more of the newer progressive lenses can handle
    these chores, while providing reasonably good peripheral vision.

    To date I have been wearing single vision distance glasses and bifocal
    computer glasses.

    Prescription is:

    -2.50 -0.50 100
    -2.75 -0.25 85

    add 2.25
    +1.25 computer add

    Can anyone recommend a specific lenses that would be good (or should be
    avoided)?

    Thanks

    Your vision is similar to mine, and I'm about 90% satisfied. I cannot
    find anything with decent peripheral close vision. That 2.25 add is
    the problem, I'm told. While I HAVE NO EXPERIENCE, I'm told that if I
    only had 1.75 add then everything would be much wider.

    Only your optician and some trials will tell you if that is enough;
    I'm 99% sure it would be for me as I like to read at 24" or so. I'll
    try to talk him into it next exam.

    Lens ... my first were Essilor (Varilux) Panamic, their "premium"
    product. I absolutely hated them. The problem is partially that
    their optimization and my desires conflict ... they try, I think, for
    pretty good everywhere, and in doing so peripheral SUCKS. My optician
    also mounted them too high.

    For MY desires, I would have single vision in a top area like the
    top/bottom executive grind, with progressive in the lower third;
    AFAIK, that doesn't exist. We switched to Essilor Liberty, not well
    known (and their entry level, lower cost in Europe) product (same
    price as Panamic, I was told, here in the good ol' USA) I have
    satisfactory distance and peripheral, and marginal mid and near;
    marginal for almost total lack of peripheral, not for center
    sharpness. They are wider than the Panamics, however.

    I've heard plus and minus on the AO b'Active; it gives much that I
    want, and may be exactly; the available literatuer is lacking, and my
    optician has no experience, nor good input from her lab. I may gamble
    and try it.

    Be sure the frame you select are pretty tall; mine, at 34mm, are too
    short. When I do it again, 38mm will be my minimum.

    Hi rck,
    I don't have any tips for lenses for pilots, as I will leave that to the
    professionals in this newsgroup.

    Only thing I want to do is to forewarn you to disregard any postings from a
    person named Otis. He is not in the medical profession and not in any
    position to give medical advice.

    Thanks for the tips.

    I had not heard of the AO b'Actives and can't find much about them
    except their marketing claims so far.

    Thanks Carl,

    I am in the Milwaukee area. If anyone can recommend an optician with
    progressive experience with pilots around here I would appreciate the
    referral.

    Robert Martabello (sp?) of Roberts Optical is one of the best opticians in
    the US, especially for progressives. I believe he is located near Milwaukee.
    He is a frequent contributor to this newsgroup.

    I went through a search for a progressive with a similar prescription
    about a year ago. My add is also 2.25. I settled on the Johnson and
    Johnson Definity design:
    http://www.ecp.definity.com/patient_benefits.htm#zone

    They have a very smooth and broad transition through the intermediate
    zone, a broader than usual channel width, and are much better than the
    Essilor lenses I wore previously. Although I am not a pilot (I am a
    teacher who uses the computer a great deal) once I was satisfied with
    the Definity the optometry lab where I got them prescribed a pair for a
    pilot and report that he is quite satisfied. They cannot be made
    locally, but your eye doc will have to send the prescription to the
    Virginia J&J plant. They must also be fitted precisely, centered over
    the pupil. In the first pair the fitting was a little off so I had them
    remade. The second were "perfect." I understand that Essilor is in the
    process of buying Definity from J&J, I just hope they don't wreck the
    design or manufacturing process of this great lens, since IMO it is
    better than anything Essilor makes itself. BTW, I first thought that I
    might get another pair optimized for computer use. But the Definity
    work so well with the monitor that I decided against a separate pair of
    computer glasses. I had to get the Definity lab and my eye doc in
    contact since no one in my area previously worked with Definity. It was
    worth doing this.

    Thanks Dennis,

    I have some progressives being made for me right now and I will report
    on my degree of sucess with them when I get some experience with them

    I just went through this for the first time myself.

    Got my first pair of "progressives" two months ago - and they were, for
    me, a disaster! The distortion at the sides was such that when turning my
    head from side to side - as at a stop sign and checking for oncoming
    traffic to the sides - was so bad that it gave me a mild vertigo!

    I would be extremely nervous to be flying with a pilot who was wearing
    these lenses for the first several times.

    I returned them for "lined" trifocals, and found them to be perfect for
    driving - far distance sharp, instrument panel sharp, and (when stopped)
    close range for maps also perfectly sharp. Peripheral vision is good, with
    the same grind as the top (distance) area.

    The down side is that they are useless for reading or close work because
    they involve constant head turning for even slight 'side glances'. (I use
    my peripheral vision a lot.)

    The answer, for me, was to keep my old 'close-up' glasses for general
    bench work and most reading (but they are now fuzzy at closer than about
    18 in.).

    I have no idea who the lens supplier was, but I bought them through Sears
    Canada's "Sears Optical" division.

    From reading this thread, I can only suggest that you shop very carefully
    AND try to get a "full value return" for any that are unsatisfactory.
    (Sears Canada Optical allowed one return, but no price difference refund
    for the lower cost 'lined trifocals'.)

    I will continue to follow this thread for more very useful information!

    Oh, I don't know. I've made a number of progressive lenses for pilots.
    Many of them have fairly mild prescriptions anyway.
