    Transitions Peeling???

    I had a patient bring in his glasses from 9/08 Creation poly transitions with carat advantage. It appears as if the AR coating is peeling however the patient just walked in from outside and the peeled area was clear, which I verified with our transitions demonstrator. Anyone ever hear of transitions peeling? Do you know could a lab strip the transitions off?

    that's funny because I just had a patient show me her poly transitions no AR, and a part of the lens is peeling. And she got them last year.

    Are you absolutely sure they are Transitions. Transitions is embedded in the material itself. LifeRX lenses on the other hand are garbage on a stick.

    The only thing I could think of is if the customers are cleaning chemical abusers. The penetration of the Photochromic material is not all the way through. Habitual Windex or other cleaning agents may destroy the lens like any other Poly lens.

    I know I don't have as many years in as you but I've never seen Transitions delaminate on any material even poly.

    The progressive is the creation Transitions are the only listed photochromic option.

    A Transition lens is made by Transition.................a photochromatic lens can be made by anybody from China to Thailand.

    Every lens manufacturer in China makles some kind of photochromatic and they are not all the same.

    Same here

    We've had TONS of the same problem lately, for about the past year or so. I have verified with ours that it is in fact Transitions product. Prior to this experience, I was always led to believe that Transitions were embeded in the lens as well. This has proven otherwise. It's odd, because we never had a problem prior to this past year and now we see at least one to two a week. Definitely transitions, and definitely poly. Have not had the same problem on any other base lens materials as of yet.

    Don't know where the progressive comment came from.....

    Transitions last year had a big problem with knock-offs....A la Ray Ben, G&G etc. They reasserted that dispensers dispense a numbered certificate with the eyewear. Maybe these peeling lenses are knock-offs used by some unscrupulous lab or a moron product buyer.

    Photochromic embedded ?

    This ist true for normal index (CR39 similar) Materials.
    However on higher index Materials (typically 1.6 - 1.67 - Poly...) the photochromic Molecules can not be embedded into the matrix of those plastics but must be rather applied onto the plus side of the lens via a thick layer (similar to a Hard Coat).

    Any layer, if applied incorrectly, can peel. Hence the white spots where the photochromic Layer peeled off - clear white lens underneath.

    The lens markings are creation, the lab bill says transisition. We do give out the cards for the transitions, I bet I couldn't find a customer who still has theirs a week later let alone a year later.


    Moving on... OK poly sucks and Transitions on poly has experienced similar problems. Does anyone know if they can be stripped with any probability of success?

    I say no. The lenses are shot. Time for a new pair.

    Sorry I just read right past (over) the Creation part. Calm down, maybe check your sugar.

    Back to chemical check....Done any asking about what the customer uses on their lenses or does for work that may break down the outer coat on the lens?

    The key to Georg's good answer is that any material that blocks UV light inherantly cannot contain any photochromic material, or they will not activate. The photochromic must be added onto the lens using a layer/material/emulsion/coating that does not block UV.
