    Good Day All,

    Which progressive lens would provide me the best vision?

    I am looking at Zeiss and Rodenstock lens and frames but I am open to other

    I would like a wide field of view (peripheral vision) if possible.

    My prescription is:

    O.D. +0.50 -0.75 X 090
    O.S. +0.50 -1.00 X 094
    Add +1.50

    I work at a computer.
    I also do hands on repairs of controllers and sensors, sometimes in dimly
    lit areas.
    I also bicycle long distances and need help seeing in the distance or doing
    quick repairs.

    Lately I have had to pick up reading glasses and I have also noticed that my
    intermediate and distant viewing are also blurring.

    Other than that, I have not worn glasses the last three or four years.

    Kind Regards and Thanks in Advance,

    Father Times

    PS: I once bought a pair of glasses that just corrected my stigmatism and
    allowed me to read distant street signs.

    Good Day,

    Would the optics be better for my prescription in a mid-index such as
    Rodenstocks or Solamax?

    Any brand preferences or advantges in mid index lens?

    O.D. +0.50 -0.75 X 090
    O.S. +0.50 -1.00 X 094
    Add +1.50

    Kind Regards

    Your prescription is minimal and there is little advantage to a mid index

    If you work on a computer and have little need for good distance vision
    while on the computer, you will have the largest field of view with the
    least distortion with single vision reading glasses instead of progressives.
    Even if you need some distance viewing, if you had them made as half eyes
    you could peek over them for distance (your distance prescription is minimal
    and naked eye viewing should be adequate) and push them further up your nose
    while on the computer.

    For biking, get distance glasses that double as sunglasses either with a
    clip on or with self darkening lenses. Carry your half eye readers for

    If you do very tiny near work at close range, you may need a pair of
    drugstore +2.50 for that.

    Good Day,"Mid-Index" is too vague. Some people may consider a mid-index to be either
    1.54 or 1.60 due to the fact that the use of 1.66 and higher lens index
    powers have increased dramatically in the last 5 years.

    Sola Spectralite material (1.54 index) would be a good choice. It has
    excellent optics (abbe value is 47) and is fairly light. Whether the Solamax
    design is the best choice is debatable, but many people like it. The
    high-end Rodenstocks seem to be preferred by many, although they are not
    cheap. I have heard that Sam's optical was running a special on Rodenstock
    progressives, although it may be expired.

    Just remember that each manufacturer (Sola, Rodenstock, etc) usually has
    several different Progressive lens designs (in addition to several different
    materials) in their line. In your case you referenced a particular lens
    design from Sola (Solamax design) and a brand (Rodenstock) that has several
    different progressive lens designs. Sola also has the Percepta progressive
    lens designs in addition to the venerable VIP progressives.

    Rodenstock is a lens manufacturer who makes several models of PAL's
    including the Progressiv AT, Progressiv XS, Progressiv Life 2, and
    Multigressiv 2. They each have different PAL designs. The ones with
    Automated Prescription Technology (each lens custom made for your Rx without
    using base curve blanks) are usually considered the best.

    Sola is a manufacturer who makes several models of PAL's including the
    Solamax, Percepta, VIP and others.

    Each of the manufacturers usually offer several different lens MATERIALS for
    each of the PAL designs, such as CR-39, Spectralite, polycarb, 1.60, etc).
    Some of these materials (like Spectralite) are proprietary to the

    So your statement about which is better (Rodenstocks or Solamax) is
    comparing apples to oranges. However, the high end Rodenstocks with
    Automated Prescription Technology are usually considered to be the most
    advanced designs, which is not surprising when you see the prices. Many
    people with your Rx are quite happy with Solamax, especially if you don't do
    a lot of mid-distance work (like on a computer).

    Most people would consider the high end Rodenstocks as someehat of an
    overkill for your mild Rx. But if you can afford the high-end Rodenstocks,
    then they will likely be somewhat better and more sophisticated designs than
    the Solamax, but the Solamax has a better mid-index material (Spectralite).

    Good Day All,

    It is a polycarbonate world when you go to Sam's, Wal-Mart, Sears and Costco
    (I'll try BJ's later). They all describe polycarbonate as superior in all
    aspects. Likewise, they do not know what they are really offering in Zeiss
    and Rodenstock. So if I'm going to obtain better optical-quality eyeglasses
    it will be through this group's guidance.

    Wal-Mart's polycarbonate ultras have Zeiss scratch resistant treatment and
    Crizal Alize AR for $217 with supposedly a wider mid-distance channel. Of
    course they do not provide their abbe value.

    Unfortunately, I do a lot of computer work. I was leaning towards Solamax
    Spectralite but with its narrow mid-distance channel it does not seem a good
    choice for me.

    If I go to an independent optician, I would at least like to know
    before-hand what the best lenses / material are for my prescription and

    O.D. +0.50 -0.75 X 090
    O.S. +0.50 -1.00 X 094
    Add +1.50

    Thanks to Everyone in Advance (and for your previous replys),

    Forget about what they tell you. Just get something besides polycarbonate. I
    assume you can still buy at a shop even if you don't agree with them about
    the choice of lens material (assuming they offer other materials). For your
    Rx, you don't need a high index material. You could probably do fine with
    CR-39 (regular plastic) since your Rx is mild and thickness/weight is not
    going to be a problem.

    YOU MUST ASK TO SPEAK TO THE HEAD OPTICIAN. If you don't like what they say,
    go to another Wal-Mart.
    Abbe value of all polycarbonate is 30. Doesn't matter who makes it. Zeiss
    lenses are good in general, but if you can avoid the polycarb you will
    better off for your Rx. I am surprised that you cannot get other lens
    materials besides polycarb.
    Keep in mind that most PAL's have narrow mid-distance vision and are not
    ideal for computer work unless they are custom made for mid distance in the
    upper part of the lens (which means you cannot use them for driving). There
    are specialized "computer" PALs such as Zeiss RD. Or maybe get a pair of
    bifocals just for computer work (with far distance set to about 24"). Talk
    to your OD about this.
    It depends on how much you want to spend. The high end lenses from
    manufacturers such as Rodenstock, Zeiss, Varilux, Sola, Hoya, are all good.
    But you don't necessarily need the very best lens design for your mild Rx
    and you only need a mid-index or even CR-39 lens material.
