I have a few pair myself. Of course I was very skeptical at first. What happens is there is a .6 diopter added (in +) or subtracted (in -) from the bottom of the lens.
However, I do notice a lot. When I work a 10 or 12 or 14 hour day I do notice that my eyes really are not sore. But with every other lens I have had my eyes were very tired after that length.
The major problem is it is not something really obvious to the client. I mean we can see transitions change, we notice the benefits of AR, but it is hard to show the client the benefits of this lens.
Am I correct in interpreting your post, are you over plussing .6 diopters at near only? Chris.
any special fitting requirements?
that is what I was told. Of course, remember, this is Essilor who does invents lots and has little information about all of it. However, I doubt a mm or two difference on this lens matters.
So this is a SV lens with a 0.6 add? Sounds like a PAL for a 37 year old. Very progressive!

Prdon my asking, but how could it be a single vision lens if it has two different prescriptions on it?
How can a lens be labeled an "anti-fatigue lens"? What if it is given to a pre-presbyopic exophore or someone with convergence insufficiency? Then would it be an "anti-anti fatigue lens"?
Since this is a PAL or blended seg, it has to be generated, right? My labs don't know anything about it.
Is it available in the US?
What is the fitting height recommendation? or is it fit like a round?
What is the cost relative to a SV? FT? computer lens? (just answer more, less or same)
And finally, what materials?
I want a pair for myself since I won't admit that I need help reading.
Thanks. I love one-upping the lab guys.

Yours truly
Thanks Rinselberg for the links. It really seems like a progressive with a low add in disguise. How can they call it a single vision lens?
I could see where the lens can benefit some people. Actually, optometrists have been preaching for a century that low adds can help people with near work, children included.
But I can see the advertising coming. Building a niche market..."Oh I want those lenses that relieve your eyestrain compared to regular lenses."
According to the essilor.co.uk website provided by Rinsel, the anti-fatigue lens is not suitable for an exophore or persons under 16 years of age.
I found my answers. Not available in US yet, but planned later this year (it's already pretty late in the year). Materials will be Orma (CR-39), poly, and 1.67. CR and 1.67 are available now in Europe. Range in Europe is +6.00 to -10.00. You fit it like a progressive, however the fitting can be done on the pupil to 2mm below.
If the distance has little distortion, I would like a pair for computer use.
Pete, do you have anything to add?
I would not use the term progressive, because it does not have a channel. You may want to say multi-focal. The distance does not have any distortion that I notice (compared to other 1.67 single vision lenses.
I wass just working on the information on this lens and this is on the Luzerne web site
Available in clear CR39, polycarbonate and 1.67 materials.
When ordering, please supply the distance Rx, monocular distance PD’s and fitting height dotted to the center of the pupil
Recommended minimum fitting height is 13mm.
Minimum B measurement of selected frame is 23mm.
Systematically available with EVC, Crizal, Crizal Alize and Avance with Scotchguard.
Shamir has a digital design called the Relax that is also an anti-fatigue single vision lens. We also have our own in house digital anti-fatigue single vision. They are both available in a wide variety of materials, not just clear. They are both eligible for crizal as well.
I'm VERY Skeptical of these lenses. Even More so for anyone under the age of 30. All it's going to do is kill their accommodation sooner and even possible require Prism later on as well because of the lens design having a Small, but yet still an amount of prism to draw the eyes inward.
There are MANY HUGE debates out there about these lenses epically for younger kids and teenagers.
My Shamir Rep is ABOM and a former Optical Teacher at a large School and even he is skeptical about the lens and the possible problems it may cause later on.
And YES it is considered a SV Lens even though it has an addition power to the lens. Because the reading power doesn't go over 0.7 it's considered to still be in the single vision range.
Better to remain silent and be thought a fool than to speak out and remove all doubt.
