The wrap does cause more base out, that is what they said. To compensate design the lens with counterbalancing base in prism. Opticampus calculators are great, and so is Darryl's Spectacle Optics...

No you neutralize it at the prism reference point and then any existing prism should be measurable by the displacement on the lensometer reticles. When inspecting always measure where the PDs, seg...

Absolutely, in a progressive you can't just fudge the PD, you gotta grind it.



True, there is little reason to manually compensate anymore. But you gotta know to order that too. I've talked to...

I don't even think that's bad if you are figuring in all the patients that never even step foot into your optical.

That will cause the clear line anywhere that is rolled, but if you move the bevel to the very front edge of the lens it shouldn't be apparent from the front. The polarization filter is laminated into...

Disagree. There is nothing detrimental about polarization. The only thing Lightpro is claiming it is superior in is "Contrast and depth perception" and that's just because they transmit more light....

That would be very interesting. Would that mean ESSILOR WAS RIGHT ALL ALONG, and now even Zeiss is copying their decades-old philosophy?? :giggle:

Wrap frames induce BO prism, so BI prism is needed to compensate. It should be surfaced/generated prism for best effect, but of course simply decentering optical centers can achieve that too. If the...

If the optical manager is only responsible for the optical, and the doctor isn't chewing her out for poor capture, then capture should be the number of pairs sold divided by the number of people that...

Nah, flash mirrors are primarily cosmetic, they don't reflect enough light. If I mirror, and I do on maybe 30% of my suns, it's a solid.

I love KBco mirrored blanks because you can surface or...

Wow, this is golden information! Thanks Uilleann.

Sorry can't help there, I have no experience with HOYA products. But I'd like to know. Do we have a HOYA guru here?

My reasons, in order of importance to me:
You can't readily put the best ARs on tint for the reasons I mentioned, so you have to go for more basic "spray it on anything" ARs. Polarized are...

My go-to guess in such situations is the pt is slightly underminused. The sun lenses are so dark the attenuated light reveals the issue, while it is not noticeable in the clear. What drk says: put...

100% Andy. Zeiss likes precision and shoots for maximal clarity, and likes to tout "zero distortion above the 180". Well, if none of that unwanted astigmatism is in the corridor and as little as...

You are correct they do still mandate 100 frames available that are covered, so I do have those. Luckily the frame reimbursements aren't SO low that you have to provide crap, you can get plenty of...

Vision care plans do not (and may not) dictate your practices and policies. One is not forced to offer or provide "just what my insurance covers", one MAY say no. Accepting customer demands is a...

I do regularly get more reasonable questions from my customers about why their expensive "scratch proof" lenses I made them 3+ years ago are scratched or crazed. Of course first we all remind eveyone...

Update: I just submitted an XR Design on VSP and the "V2702 - Deluxe lens feature" line item is only appears in the calculations IF you input values in the custom measurements fields. If you leave...

It requires no additional measurements, but you may supply them on the Design (notice the input fields will be available on Eyefinity). I think then the only difference between Design and Fit if your...

This is perfect, I'm training an apprentice right now and she's planning to test in a month and this is excellent guidance. Thank you Krystle!

There will be no similarity. Essilor and Zeiss have fundamentally different progressive design philosophies, and I would even opine that they are the most diametrically opposed designs on the market....

Probably the most time-consuming interaction between optician and customer is frame selection. This is not a highly technical task, and with a few simple instructions on frame fit any staff (or even...

I am in a small 1.5 doctor Optometry practice. We don't have storefront so our walk-in traffic is minimal, but of course we get outside Rxs. First, as you said, our business model revolves around...
