Varilux Physio vs Varilux Physio360

    Could someone please explain the difference between the Physio and
    Physio360. I've been to
    Varilux.Com, but they are far from clear on the target market of
    either product.

    I know the following question has been asked and answered in many
    posts, but I am getting ready to
    make a purchase and just want to be sure (the retailers tell me the
    opposite of what I read here)...

    For a light prescription using a Varilux lens and a regular metal
    frame, I am better off getting
    a standard plastic lens as opposed to a polycarb lens... is that
    generally correct?


    Thanks

    For your Rx (previously posted) with a regular metal frame, 1.50 plastic
    (CR-39) is fine. If you want a thinner and lighter lens from Varilux, I
    would go with the 1.60 plastic, which is optically much better than the 1.59
    polycarb.

    Looking at the Varilux web site, it appears that Physio 360 is a finished
    lens with Crizal Alize AR coating included, whereas regular Physio is
    available in traditional unfinished lens which is custom finished at a local
    lab. But I cannot guarantee that this is the only difference.

    All Physio lenses are made with patented technology by essilor. The
    difference between the 2 designs is the Physio is a rear surface
    control only, while the Physio 360 has aberration control on both
    sides.

    While there is not a huge difference between the lenses, we have found
    a wider reading zone in the 360 and crisper distance optics. With the
    exception of higher scripts and higher base curves (where the 360 can't
    be ground) we now are using the 360 exclusively. The few dollars
    difference in cost is irrelevant once function and ease of adaptatin
    are factored in.

    There is no "target" market for these lenses per se. Essilor does not
    and never has made lenses for a specific purpose as some companies,
    such as Sola do. I find most of my patients do a bit of everything, so
    a lens for computers is often useless for reading etc. Essilor has
    always aimed at lenses for general use that work in most situations.

    The Physio 360 is the best lens I have come across and I can highly
    recommend it. For low scripts, stick to CR39. Airwear for higher
    scripts and industrial needs.

    I should have mine any day now. (low script with a 2.5 add).
    Drilled frames so the doc recommended poly. I elected to go
    for 1.6 (Somehow I thought it was 1.67 instead of 1.60?) and
    transitions.

    First pair from the lab they had drilled one side for the frames
    crooked and it was poly instead of 1.6. Doc sent it back but
    not before I tried them out for a couple of days. I don't have
    anything to compare against except my translating trifocal
    rgps but the crispness and clarity was stunning.

    The 360s also come with ClearGuard (antistatic). I'm don't
    know if that is available as an option on the Physio.

    1.60 and 1.67 are two different lens materials (among others) available from
    Varilux.

    Physio do not come in 1.6 material.

    You are correct. We don't get it as an option here.

    Robert, the 360 is freeform on both surfaces, the Physio on the back
    only. The MF is purely front surface on both, but the aberration
    profile is better controlled over both surfaces on the 360.

    The Ipseo was never moulded. It was laser generated front and back
    from day 1. That was the reason to test head/eye movement so as to
    vary the reading band accordingly.

    You americans are very funny then if you get a generated physio as
    they are diamond cut on the rear surface everywhere else to account
    for the aberrations of a given prescription. You can't get that from a
    generator, thus nullifying any benefit of the lens.

    No, Essilor is very funny.
