My understanding is that the Definity starts out with a Plano lens. Both sides are ground to achieve a 50% wider useable area by splitting the add power between the front and back surfaces....
That is correct.
The 360 Digital Surfacing is designed to match the front surface. The Physio 360 is processed using Alize w/Clear Guard, which is and anti-reflective & anti-static. Physio...
If you take a look at the link and scan the availability chart, most will be happy to see that there is a 400add available. The actual range is .75 to 3.50, (no 3.75). The 400 add is a nice bonus.

Just wondering, are you using a different generator when the prism occurs? You mention the V50, but that generator wasn't causing us as much problem as the SL2's we have. Turns out that it's...

Try looking down at the lens using an overhead light reflecting off the concave side of the lens instead of the front side. Usually I can find the marks just at the edge of the reflection.
Just for the sake of clearing up any misunderstanding, AR does not absorb or reflect UV light. UV coating must be applied under the AR.
By the by, my opinion on children and AR is that it...
On occasion I refer people to the optical instrucor on the internet. This puppy I down loaded right to my desktop...way cool! Nice job

Hey there! We just recently switched from wax to alloy, also using the PLA's. Your problem is HAUNTIngly familiar! Did you get it straightened out? I'm very interested in how your...
Mister Meister, (:) I've always wanted to say that)
Caught your site last week, verrry nice. An associate EM'd it to me, as I'd been off the board for a while. Wasn't smart enough to look...
Daryl, I'm not that great with paper calcs but how did you get the 2.25 BD OD, 2.25 BU OS? I ended up with 3.66 PD between the two. And if so, why is it requesting 4.25 PD slab. It just dawned on me...
The problem is that I can't figure out how to specify a prism amount to fix this, if indeed it does need fixing. DVI is the coolest thing since sliced bread, far be it for me to second guess it's...
Hey guys, any of ya got yer ears on?
Pete and I are having a problem. Our work ticket says -3.25 SLAB -2.00 HIGH with 4.25/100 in bold. I've been reading this incorr apparently because we've...
Thank you all for your instruction. It's nice to know, (and maybe a little unfortunate), that other people can relate to my circumstance.
I work for a wholesale manufacturer. The client is one...
I wish it were that simple. For some reason we are hanging on to this client. I feel an odd sort of reluctance to say, "let's not do this anymore",
one: because I don't give up easily
and...
Having worked in the industy for a few years now, I've had the opportunity to work with the general public, doctors, opticians, business owners and frame stylist.
I appreciate the difference and...

There's a great discussion on this subject but I don't know how to link it, so, let's see if I can get you lost giving directions. At the top of this page hit search, then type in...
