Varilux Ipseo

**Mivec** · 03-24-2005, 05:57 AM

Can anybody explain the difference between the ordered power and the measured power on the Varilux Ipseo packaging. Is there any formula to calculate? How do I know if the mesaured power Essilor provided will benefit the wearer. :finger:

I just heard of this lens the other day. It sounds a lot like pentax's af lenses. There realy is no calulations that we figure out it is already done by the manufacturer. I guess that you have to trust the calculations and do a little bit of trial and error. Your best bet is to contact Pete Hanlin he works for essilor and is on here some times.

It's actually nothing like the AF lens. That lens is not even as advanced as Panamic. Ipseo is the first lens, to really take in the importance of eye and head movement and design a lens based around this information. You will see lots of people try to imatate this design, they always try to one up Essilor. But they never do.

Ipseo is the first lens, to really take in the importance of eye and head movement and design a lens based around this information.

Keep in mind that SOLA introduced an eye-tracking system for selecting progressive lens designs to the market over 5 years ago (in France, even). The technology was used exclusively by Grand Optical for a number of years, and assesses eye movements for both near and intermediate working distances (not just a single working distance), as well as eye declination.

You will see lots of people try to imatate this design, they always try to one up Essilor. But they never do.

Since I can already see where this will end up going, I'll also add that SOLA introduced SOLAOne Ego in Europe over a year ago, which varies the viewing zone configuration of a free-form progressive lens based upon wearer lifestyle feedback captured by a PDA-based dispensing tool. (Wearers with more near vision demands are given a design with a larger near zone, and vice versa for wearers with greater demand for distance vision.) Moreover, the lens is completely optically optimized for the prescription in the as-worn position.

Most recently, SOLAOne Ego+ was launched, which is a free-form progressive lens whose design is quite literally "morphed" on-the-fly for each wearer based upon both lifestyle feedback and fitting height (that is, both the viewing zone configuration and the corridor length are manipulated). This lens is also completey optically optimized for the prescription in the as-worn position.

If Sola's technology is so good, why were they bought? There product is and has been average at best for years, that includes Sola one. It is not a true custom lens, and thier Itracker system has been around for almost 8 years, not 5. I dosen't matter though. We can all believe what we want..have a good day

I just have a small question. Who do you work for?

I think your question answers itself.

Sola one. It is not a true custom lens

Before I respond to this one, I wanted you to clarify whether you are referring to semi-finished SOLAOne, SOLAOne HD, SOLAOne Ego, or all three.

thier Itracker system has been around for almost 8 years, not 5.

Yes, our technology has been around (in development) for 8 years. But we first introduced it into a retail location close to 6 years ago. But are you defending Ipseo as "newer" technology by asserting that our iTracker system has been around for 8 years?

Best regards,
Darryl

Gee I think that SOLA was bought because they have good products and a strong following. They are a good investment. And yes we all can belive what we want. That is obviously what you do with no regard to facts.

Yeah, it was kind of a no-brainer. SOLA has a strong global presence; good market penetration in the US; capable manufacturing and distribution facilities; excellent human resources in marketing, sales, and R&D; and (to address Genius's point more directly) a great deal of intellectual property in areas important to Zeiss.

Speaking as objectively as possible, I think that the merger of AO*SOLA and Zeiss is probably one of the more sensible alignments I've seen recently in the manufacturing side of this industry.
