    Definity discontinued....

    It seems Definity is being discontinued.....which is a bit of an issue since long-time Definity wearers almost never like any other lens. I am thinking Hoya Lifestyle might be the closest thing available, of course they are significantly more expensive, especially for a vsp order. Any thoughts or suggestions?

    I knew it was slowly being phased out in the more esoteric materials, but was under the impression that, like say Image, Comfort, and Natural, it would likely be available in at least CR and poly for a long time yet to come. To the best of my knowledge, with all the fancy lens wrangling of the last 15 years or so, literally no one has come up with a viable replacement for that design. And for the people it works for, it's really a great optic. I hope it still has some life left in it, or a decent "modern" analogy is one day released to take it's place.

    Are we sure we're talking about the design?

    I got a feeling the Definity 3 will always be with us.

    It still is with us...although I have heard it was to be discontinued YEARS ago.

    Over a year ago, I was talking to my Essilor rep about the new Comfort Max progressive that was to be released. We had some scheduling conflicts, plus Covid affecting everything, so I was not able to get him in office to do official staff training. So I asked him to give me the fast and loose training so I can offer to my patients sooner and train the other staff.
    He described the "new" Comfort Max 2 as a PAL with upgraded corridor with a "boost" of power in the intermediate. To me this sounded very familiar, so I asked him point blank "isn't that the Definity Dual Add"? And he acknowledged the similarity without outright saying it was the Definity Dual Add.

    So, maybe there is a difference between the two, but to me it sounds like one of the Definity line PALs has just been rebranded.

    Welcome to Optiboard DurhamEye!

    Sharpstick777 hasn't been heard from lately but was always a must read.

    Great thread from our Hall of Fame Forum:

    "Barry,
    I have defined a few basic Free-form design types based on corridor emphasis and distance width based on FF mapping we did. These are only possible in Free-form.

    T Design = Distance clarity edge to edge (primary zone gain), narrower intermediate, narrow to moderate reading... Auto II (most Shamir), Seiko Succeed/Supercede, et al.

    Free-form Hour-glass = A little gain in most zones, but not edge to edge clear in any one. Wide Distance (but not edge to edge), moderate int and wider reading. Its a balanced design, general purpose lens, with no single emphasis. and Comfort DRx and Physio DRx, Steath Pro SD/MD

    Plus Shape = Reading and Intermediate are very wide, but distance is not. Distortion is essentially moved to the four corners, which balances spacial distortions, and effectively widens the entire effective corridor, which is more cylindrical. (Definity, Hoya iD Lifestyle)

    Barrel Shape = Wide Intermediate, slightly narrower distance and reading. Basically instead of putting the narrow end of the progressive cone at the pupil, it turns it around and puts the wide end at top instead. Distortion is moved to both the top and bottom edges, but gives about 4X the distance width as most Plus lenses. Basically, its two corridors, stacked with their wide ends together. The Seiko Surmount is the only one in this catagory at this time.

    V Shape= Edge to edge distance, wider intermediate, but very narrow reading. Ziess GT2-3D is the only lens in this catagory.

    Fountain Shape = The newest design, its like a T shape but instead of the narrow part of the corridor at the top, the narrower point is lower in the middle between the intermediate are reading zones. The intermediate ends up being a little wider, with a little lower declination. Reading is a little lower. Distance is edge to edge, and because of the distortion being pushed down, and away from the central view, the feeling is terrific. It turns into two intermediate zones though, one high, and one lower. Two lenses in this category, The new Shamir InTouch and the new Seiko Supernal. Because they start the intermediate lower, its good for laptops, but the reading is little lower too. Fit on Center. I have to dig a little deeper in both lenses to get the fine print. Reading width is OK though.


    [=Barry Santini;452873]IMHO, progressive design is not what has become too complicated, but rather the issues surroundimg defining progressive corridor between designs/companies in a more standardized way.

    Think boxing system for progressives."

    The Hoya Lifestyle 3 should be a good substitute. I literally JUST put a patient back in Definity because he couldn't adapt to a Varilux. So next year may go ahead and try and get him acclimated to Hoya, just in case.

    The more expensive Definity 3 will be the only Definity option soon.

    Some standard Definity lenses are still available but my Essilor lab says not to count on them in the near future as well.

    My tendency will be to switch them to the 3 and if they want a cheaper lens manage their expectations so a variation of Ryser's Rule will apply.

    Ryser's Rule- "The success of a progressive is directly proportional to the motivation of the patient to wear a progressive."

    I reference Ryser's Rule by name to patients at least twice a week. Chris lives on.
