Free-Form Technolgy

[For-Life]

Now I kow that Free-Form is a name trademarked by a particular company, but I will use the term for simplicity.

When I was told about the Varilux Ipseo I was really interested in its technology; however, it does not seem like I will be able to use that technology for a while. What I wanted to know is for those of you who have used the technology if you could answer the following questions:

1. Which lenses have you tried?
2. From those lenses what have been the results of use of that lens?
3. Comparison-wise what has been the price of them (for certain reasons do not post the actual price, just compare one by expense)?
4. Of those designs what have you found to be the best?
5. If you have a conflict of interest please mention before you post.

Thank you

Has Essilor not released the Varilux Ipseo in Canada yet, or decided to push back the release date? (Thank you.)

It sounds to me that it is only in test markets or bigger markets. Additionally, with the cost of this lens I do not know if it will come to the smaller markets

I will give it one last goal. I just read you guys talk about these lenses a lot so I want to make an educated decision with that. Thank you.

Lenses I've tried:

Rodenstock Multigressiv II
Zeiss Individual
Zeiss Individual Short

Multigressiv II is not a totally free-form lens. The back surface is freeform; the front is the standard Life 2 design. Multigressiv II will compensate for anomolies caused by the prescription, but does not adapt for fitting issues like vertex distance and panto. Zeiss Individual and Individual Short, as fully freeform lenses, do all of that.

My Rx is not that complex. OD: +2.50-0.50x90, OS: +3.00-1.00x95, Add 2.50.

I found Multigressiv II to be a fabulous lens. Clear, relatively undistorted distance vision even at the furthest periphery. Good, wide intermediate. Reading area is fine. More to the point, every high astigmat we've fit with Multigressiv II has been happy. One guy, with 3.50 cyls, told us he'd never seen as clearly through any pair of glasses as he does through is Multigressiv II.

Zeiss Individual and Individual Short: I wear both. I actually prefer the Short. The intermediate zone feels wider to me, the reading area a bit bigger, and of course it's higher up. I don't know for sure, but I suspect Zeiss eliminated the drop on the Individual Short just as they did on the Brevity. Both lenses have supurb distance vision, like the Multigressiv II, and the intermediate on the Short and Multigressiv II are comparable. In my view, the intermediate area on the regular Individual is a bit skinnier. Everyone we've fit with the Individual or Short has been thrilled.

Zeiss Individual and Short are available only in 1.6 and only with Carat AR. Price is about $250 per pair through our lab.

Multigressiv is available in CR39 and 1.6, with or without AR. The AR is Rodenstock's Solitaire, appiled in Germany, and comparable to Carat's old formula. CR39 without AR costs us $95 through Rodenstock. The 1.6 with AR costs us about $165.

Multigressiv II is surfaced in Germany, takes about 10 days to 2 weeks to get direct from Rodenstock. You can purchase the lenses uncut from Rodenstock with no problem. Zeiss Individual is surfaced in the US or Canada, is available only through authorized wholesale labs, and recently has been taking nearly a month for the lab we use to get.

My assessment: I'd use the Individual or Individual Short for people who are phobic about progressives, or who have anomolies like convergence differences between the two eyes. I'd also use it for minus Rxs, as we've had more success with Zeiss than any other design with our myops. I'd use the Multigressiv with hyperops (like me), anyone with strong astigmatism, and (as with the Zeiss Individual) anyone who's phobic about going into progressives.

Dear Andrew Weiss vbmenu_register("postmenu_88046", true);
Optical clairvoyant

Please try Individual Free Form PALs like " Rodenstock Impression ILT 1.6 High Strength Plastic ABBE 42 "


Rodenstock Impression ILT Plastic 1.6 ABBE 42 is double better quality of vision at distance if you compare to Ip... 1.67 ABBE 32 with the price difference 2 time up.

Adaptation of Impression ILT and Ip... are about the same , they are instant adaptation PALs.

In case that CVD not 13 mm , FFA not 5 degree , PTA not 7 , PD not 64 mm , then Impression ILT will more better than Ip...


I am sorry that I can not say their full name , because in Thailand we not have permission to say the truth about Ess... , if we do we have go to jail.
