    maui jim lenses

    Anyone know the index of refraction of the Maui Jim lenses that are called the Maui Brilliant (abbe 56)?? Supposed to be the lightest lens material out there.

    That's a good question. I asked my rep and couldn't really get an answer. I suppose it's some kind of Tribred material?

    There are only two ophthalmic lens materials that have an Abbe value in the mid/high 50's, crown glass (59v) and hard resin cr39 (58v). If it is cr39, the refractive index and density should be similar, 1.50 and 1.32 respectively, with a similar tensile strength and impact resistance. The lower Abbe might be due to the polarizing film. If true, it wouldn't be available for rimless or drill mounts.

    Hope this helps,

    My experience has been almost every pair of MJ with plano lenses is just simply poly, marketed with incredible BS to justify the ridiculous retail cost.

    I assume its similar to trivex. The mauibrilliant lenses have a smaller range of RX's than their polycarbonate lenses.

    Maui Brilliant is available in rimless so can't be CR39.

    I've wondered this myself - it seems to be a new category of material but then I don't really believe that either

    Well then I don't know how you've been around for so long and are a manufacturer/vendor and have not come across plano MJ glass lenses more often. They're what is used in the majority of their higher end glasses and poly has actually been totally phased out in Plano. It is only available in limited models these days.

    Just an fyi MJ glass lenses were up until this year manufactured out of Italy by Barberini which is another name you should know if you've been around. The coatings and polarized film however are all proprietary. Barberini unfortunately has folded to Luxottica as well and last I heard MJ was looking for a new glass lens supplier based out of either Japan or Germany considering they now have a fully operational lab there as well that rivals their Peoria Illinois location.

    I've been lurking on and off for a while but finally had to join...Product knowledge in the industry these days especially from the old timers seems to be at an all time low.

    I am an old timer and I knew Barberini very well. Vinny Barberini studied under a Mr. Gabe Cotter in high school before becoming involved in optics with Barberini. He coined the phrase "Up your nose with a rubber hose!" and used it after buying up competitors and firing all staff.

    Wikipedia is a wonderful thing. Where shall I send the bill for the therapy session?

    More for Jay 2390...For the record for all....I'm certain we all reach out for confirmation once in a blue moon.

    Barberini Italy? are u sure? vinny?

    anyway I think Mj is poly and some trivex material on high end stuff.

    They use glass on many of their Plano lenses, I think they phased out poly on their RX lenses.
