I’m following this thread, but I tend to agree with Barry. If fitting a 16 dbl, then changing to an 18, even with adjustable pads, the fit will drop Raising the prp by .5 makes sense. Less...

Reading through this thread, and I’m shaking my head.
Get over yourselves re poly. I’ve been in the industry long enough to see the improvements in poly processing.
Trivex isn’t the holy...
Yep, it’s like Kwill is trying to channel Chris in a grating way. To each their own.
Thumper comes to mind, and I’m not heeding his advice right now.
And you wonder why I’m not as active...
Agreed. Most likely causes are dirty windshields, dirty lenses, cataracts.
Under low light conditions, ABBE values have little effect. Adding additional tint for mesopic vision is never...
Yep. Autobevel. Probably done by a novice on an auto edger, or, the lab did not program their LMS to automatically do a front bevel on an industrial edger. Occasionally, I have some that I need to...
A quick email to QTMI.net would answer your question.
One of the primary issues with night driving is scattered blue light due to its shorter wavelength. Notching the specific range combats this...
You state 7yr old. At what age was the habitual dispensed? Did you keep the PD the same as the habitual, or remeasure?
One would naturally go straight to BC difference, as that’s the easy way...
Hi all,
I was invited to attend MEI’s open house in May. I signed up for 5/17. If any optiboarder is going, it would be great to meet up.
My 2 cents
Dispensing Opticians should be HC professionals.
Lab technicians should be tradesmen.
Dispensing opticians could be both.
But, the other 2 O’s will fight it, as will big...
Use an intermediate biased FF. IOT. Zeiss. Whatever.
when in doubt, in today’s world, always go with intermediate biased FF. It’s what the majority of PAL wearers use PALs for. Period.
Captain obvious here. As DRK stated, the axis shift may play a small role here, but I’m thinking PAL design. Either an updated PAL, or a corridor change.
We use the EvoGT in all of our clinics for remote tracing. We find that the scan vs mechanical is more consistently accurate, as it doesn’t require routine calibrations, nor stylus replacements. ...
We have been using the Briot Evolution GT in our clinics without any major issues. 21 of our clinics are using them to remote trace orders to us. We even have one for nylors and rimless, as its...
1. Yes you can
2. Be cognizant of frame to lens size
3. Your edger should have a “frame change” function like the Santinellis, but best option is to go old school Weco 440. No feelers. But,...
And with Santinelli no longer being independent, service is not what it used to be.
Oh my. 108. 113. 2113. Those were the days. Multiple diameter wheels. Saddlebacks. 90 off. When grinding was an art.
And the pella oil “explosions”. Did I just date myself, :bounce:
Sorry...
You may want to look at the Weco E.6. Same family as the Briot, and is quite capable at a good price point. Throughput is better than Santinelli, processes shelving and drills, and IMHO, more...
Hmmmm
Lens manufacturer? Wouldn’t happen to be Zeiss, would it?
Annnndddd…..my favorite. When they sell HEV coatings over photochromics. Like it’s gonna make a difference.
l
if you are speaking of the VE Clear Blue lenses, we sold quite a few. It was, I say was, the first blue filtering lens that have very little color cast to it. It was more of a Super UV than a HEV...
Quick solution. 5 degree incline bevel. Match frame curve. Many of today’s edgers are capable of this, even in “robo-labs”. Most LMS systems have this capability, some, more than others. It...
It is cool.
As a photographer, however, I respectfully reserve my opinion.
Crown glass should be immersed in potassium nitrate @570F . PGX In sodium nitrate @842F.
I’m thinking that the incorrect salts are being used for the material.
When I ran a lab that processed...
Rule of thumb
least minus/most plus - reverse slab - BD ^
most minus/least plus - standard slab - BU ^
Every lab should have an old school manual blocker. CAD blockers are great for bread and butter RXs. But for high RX/prism, nothing beats a manual blocker. AIT, Coburn, whatever.
