Rx: OD +8.50: OS +8.00
Add: +3.00
PD 57.5
Frame 43-19 drilled rimless (POF)
Lens shape: Custom
Lens: 1.74 Physio DRX Transitions with Crizal Avance+
Base Curve: +8.00
Patient luv'd the thinner appearance and lighter weight vs her old 1.67s (same shape)

Gorgeous!
Beautiful work sir!
Barry, you are an amazing optician. End of discussion.
Why DRX and not Enhanced?
What edge thickens did you specify?
1.74 transitions will only be, as far as I Understand, a backside-only progressive designOriginally Posted by LENNY
Requested 0.5mm edge. And got it!
Important! I upload tracings for lens layout and optimization for all my lab work.
Outstanding!
Looks awesome but wouldn't it be really prone to breaking being so thin in that index?
Why would they weight less than 1.67 in the same shape?

Density is similar, but thickness is less = lighter. She wore 2 pairs of 1.67 Trans in the same mtg now for 6 years, so I am not worried about handling.

Nicely done. Optician=Artisan!
At 0.5 ET,
Did you have to use washers on the temples or did the temples have threads throughout the screw length?
Rodenstk mtgs feature fully threaded male screw studs. 1 plastic, 1.4mm T washer on the front and 1 thin, flat metal washer on the back. I had to trim off quite a bit of these studs because the lenses were so much thinner.

Wow, wow, wow. I just sent out a drill job for a +7.50 ou with a +2.50 add. After running the numbers regarding the PD and the frame size I'm confident I'll get a good looking product but this is an outstanding job. I wanna be like you when I grow up! Hah!

Good luck with that ET
Hells yeah!
+1
I came, I saw, I left
I was thinking the same thing. +1
The screw stud is outboard of the locating stud. (edited)
Remember, I grew up drilling in the age of glass.

Nice work Barry!
+8.00 presbyopes are drooling worldwide.
Note the extension of the shape at the near reference point creating a generous near zone.
Note the +3.00 add. You'll never get anywhere close to this thin and flat with a FBS PAL.
Edge may be a tad thin, but the temporal drill point should have just enough beef to minimize breakage under normal use.
Bravo!

Edge thickness of 0.5mm would certainly be an issue to me as well *if the temples did not have a spring hinge. With a spring hinge I may have tried it too. IMHO Drilling glass doesn't really compair as the strength of the drill point is what is at question not the art of drilling. Nice job cosmetically for sure, hope it holds up for the patient. If not 1.0mm min edge thick would look nice as well.
Physio DRX is a full back surface lens right?
Looks amazing. Why not Seiko for + lens?
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.
No. Maybe. Still checking. Yes, as of 2012. My rough calculation shows you can just get +11 D on a +8 BC with a 1.74 index by using a plano back curve, or locally plano at the NRP.

I always thought the DRX lenses were backside only and the enhanceds were optimized frontside molds. Thanks for the info and again great job barry
