    Life Rx and polarized poly splitting

    Anyone else having problems with "laminate" poly lenses splitting/delaminating in grooved rimless frames?

    We've had a lot of that trouble lately with both polarized and life Rx in grooved poly. We now won't do poly rimless in those options.

    Anyone know when Transitions FT poly is supposed to come out?

    I have always been told that you shouldn't use laminated lenses, ie: polorized, in a grooved rimless for obvious reasons.

    Ditto here. And the ones I've seen had the groove set way back to avoid any contact with the laminate area

    you can use trivex ft28 trans for now. The LifeRx manufacturers are aware of the problem and working on it....we have noticed it is happening much less in the more recent batches we have received.

    Odd, I've been wearing a pair of polarized progressives in a grooved rimless frame for almost 3 years, with no problem at all. Perhaps the placement of the groove is questionable?

    Many moons ago I had a problem with polarised lenses de-lanimating because I was dumb enough to leave them on my boat (the idea was I wouldn't forget them when I went fishing). Could this be the problem, moisture absorbing in between the lanimates?

    The elements do work on polorized and all lens. How many problems have been attributed to people leaving lenses in a hot car. Best just stay away from groove frames in polorized or risk having to deal with a problem. I had a grooved pair split non my glasses once. Now they are the only sunglasses I have that aren't polorized.

    :drop:yes i have seen this happen twice in a year and a half the first pair was in a rimless and you could actually see the film seperating from the lens. the second time was in a full frame it was just ugly it happened after the patient had their lenses for a year and it looked as if a solvent had spilled over the lenses oh it was just ugly. although I currently wear the lens and have had no problems with it in my semi rimless frame I have had them for about six months and no their is no yellowing of the lens. When our practice called vision ease they said it happens in 1 percent of the lenses.

    Aside from the splitting, I notice the LifeRx lenses do not get as dark as Transitions. I started using Trivex Transitions but I found that they did not get as clear indoors, nor is Trivex (or LifeRx for that matter) compatible with Crizal coatings according to my lab. I have done a mid-index FT-28 Transitions before in a drill-mount and it's worked out fine.

    Redhot Jumper Delamination of lenses............................

    Actually grooving a lens on the lamination line and then pulling a nylon thread ariund it that has a few pounds of pressure...........................is like inserting a screwdriver blade in the same place and continously rocking it.

    You are creating material fatique of the glued part and it is just normal to delaminate. At least make the groove to the side, for or back of the lamination line.

    Since their launch in 2005 LifeRx lenses have been extremely successful in the marketplace and we are pleased with their performance. As with many new products, we have found ways in which we would have wanted them to perform better. One of those is when the lenses are exposed to more extreme conditions with respect to temperature and humidity the top layer can start to separate. This was more prevalent in the earliest lots of our production as we were still learning of the issue. We have since made considerable improvements in the materials and manufacture of the lenses and have greatly reduced the potential for this type of defect. Returns for this issue have been fewerthan 1 in 4,000 lenses sold. Review of the returned lenses show there is no higher incident rate with grooved frame mounts.
    As a further point of clarification, the issue with lens separation is not seen with SunRx polarized lenses. Vision-Ease Lens has manufactured polycarbonate polarized lenses for over 10 years and has not experiences any returns for lens delamination. Our patented manufacturing process has been proven to deliver a superior product in terms of optics, color consistency and durability. In order to guarantee you receive the highest quality polarized lens without a risk of separation, ask for SunRx by name.
    If you still have questions or doubts about LifeRx photochromic lenses or SunRx polarized lenses we encourage you to contact Vision-Ease Lens. We would like you to judge these lenses for yourself. Contact a Vision-Ease Lens Sales Representative at 800-328-3449 to learn more and to receive a voucher for a free trial.

    Grooving polarized lenses

    If its grooved in the right place you'll never have a problem with it.

    Ditto. However I have had approximately 40% of my "generic" polarized lenses delaminate, even in a zyl frame. One within 24 hrs!

    NuPolar is pretty good stuff. I don't have any bad experiences w/ LifeRx, but I haven't used lots of it.
