    I am not a fan of drilling surfaced 1.74 as it flakes so easy and tends to break down the line.
    The edge of .5 is great in freeform.
    Thanks for all the compliments, including yours Craig. I know you luv Trivex, but that index in this RX would not cut it (I think!)

If not 1.0mm min edge thick would look nice as well.
    Yeah, a 1.0mm FE would have been ok too. But...labs are notorius for wanting to avoid spolilage (NOT BREAKAGE), and if they produce a lens the "account thinks is too thin" they eat the lens, so they are biased to make thicker lenses. That said, I tend to specialize in drilling materials that other might say no to. I just had a client call me for new lenses for two pairs of Minima rimless progressives. Both pairs were done 4 years ago. Both were done in CR 39. The Rx is -0.50 sph/+2.50 add. They're still intact. The mounting, the drilling/workmanship AND the client handling all play a role in longevity, IMHO.

    You're right. It did look damn flat. Are you saying Barry is using stuff I can't get my stock lens hands on? What else is new lol. I need to learn so much because I love making the best glasses I can. :cheers:

    I can't think of any clients I know with such a high correction in this direction that don't fumble with things reaching for them without their glasses. I don't doubt the craftsmanship or skill that went into making this pair and I too don't have an issue with drilling CR especially if its a minus but man, I would have a hard time getting to sleep at night. One fumble and those things are toast. I don't mean any disrespect.

    I remember as a young pup I used to surface lenses to their limit, it always looked great but the functionality was sacrificed. I don't know your clients reaction but I remembered tears in certain circumstances. I was both proud and arrogant.

    My concerns with this eyewear 1.74 is notoriously brittle.
    Secondary that frame as you mentioned later on is rodenstock, at least 4+ years old.
    Third I question why a 1.74 transition physio drx the equivalent of a Ferrari engine would be fitted into a geo metro of a frame. In the grand scheme of things a new frame would have been a wise choice here.
    Last but not least as I was signing up for Wes conference for the opticianry summit, I read over the research paper on online eyewear. 20%+ lenses produced online don't meet the FDA drop ball standard, that standard is referenced in ANSI so the glasses made here might not meet ANSI and I must say the artisan comment is right because they are gorgeous but they are literally tenths of a mom away from being medical devices.

    As a salesman I applaud you, because that patient will have the hardest time finding anyone willing or capable of producing a similar product, kudos to a client for life.

    If this pair is a time bomb, then I bear the responsibility of the ensuing wait. I did advise the client that these need to be handled carefully, and that errant grandchildren and overly-loving hugs from friends and family are mortal predators.

    A former employee of mine has been quoted as saying that I make eyewear "dangerously thin."

    BTW, I prefer both the old Minima mtgs and the Rodenstocks to many of today's new ones. But I will admit my experience with many boutique mountings is limited at best.

    None taken and a valid counterpoint.

    Looks great - hope it doesn't craze within 6 months like most of their coatings.

    Personally, I think the biggest edging challenge back in the days of glass was trying to put 8 Base glass STOCK lenses in the +2.75 range into a Liberty all-aluminum, flat-metal 1/2 eye with the split metal eyewire...with chipping the lenses or leaving eyewire-to-lens gaps.

    Barry, they LOOK real nice! Be sure to post the pic of them when they come back in with the endpieces in one hand and the front in the other. It's going to happen!

    SO I have to wonder - with companies like Ice Tech using their zone thinning/blending tech to make lenses thinner...could an opposite tack be taken here? Could a skilled and capable tech with the right equipment create a lens like this that thickened that outer 2mm or so from the temporal edge to add that extra half mm or 1 mm to the very edge, and seamlessly blend it in with the rest of the optic?

    Just out of curiosity, how is it you can do a job like this but you can't get 1.9 glass with a 1 CT like we can up here?

    Very nice Job ,carefully edged and assembled.I was wondering if this was a front side progressive design,since a backside would have left the reading zone ectremely flat.Actually the picture seems very flat.

    I am impressed with your work ,well done.
