Ovation vs. Natural

[Uncle Fester]

Out of range in digital???

Hmmm- What's the prescription?

[AllieHind]

Had a patient with cyl out of range for digital lenses so coming back to this thread to decide on Ovation or Natural in 2024. Thank you all!!

Ovations:
- Has a maximum fitting Height about 24mm I think. The add decreases if you look lower than this.
- Not much intermediate area compared to Natural.
.

It's called "ground-view advantage". It's a good thing.

Ovations:
- Pretty much the same as Panamic - of course Essilor will say it is different to keep Panamic price higher.
- I find that the minimum fitting height to be 19mm to get large enough reading area. It is not just the add that increases as you go lower on a Progressive, but the width of the reading area increases also.
- Has a maximum fitting Height about 24mm I think. The add decreases if you look lower than this.
- Not much intermediate area compared to Natural.
- Good overall lens.

Natural:
- Pretty much same as Comfort. Good standard lens with high success rate.
- Minimum fitting height for success: 21mm - my opinion
- larger intermediate area so better for people who need the intermediate vision.
- More distance peripheral distortions than panamic
- no maximum fitting height.
-I havent heard people complain of a narrow reading area, but then the higher the add, the narrower the reading area in most progressives.

Thanks! On a wholesale level difference is more like .65. I would change the original question to Natural vs. Accolade and forget about the Ovation. Take a look at this:

Except I would forget the Natural. Materials and options are being phased out in Natural. I don't think it comes in poly trans or poly polarised or 1.67 anymore (if ever). Ovation comes in all of those. I also think that it has a noticably wider reading area fit at 18 or even 22mm compared to the Natural.

You know the interesting thing is that at 85% of the add you would be stimulateing the accomadative reserve to make up the difference assumeing that the patient had any reserve left, that in my eyes is playing doctor, not optician. I would love to hear the opinion of an Optometrists on this one.

I'm not an optometrist, but that never stopped me from giving advice;).

Part of the add determination is dependent on working distance. So therefore if the total add is only 85%, then the patient only has to move the reading distance a bit further out. Shouldn't be a big problem.

Also, the true add should actually be reduced a bit because that bottom portion of the lens is further from the patients eyes that the OC. Therefore less plus is needed.

Finally, when I check lenses I don't see this 85% number you guys talk about about. It's more like 92% on the shortest fits. And some of that is the limitation of the lensometer. In fact I see some of the lenses that read 0.06D over the add. But most of the time they are 0.06 under. WHich I suppose is about right due to the increased vertex distance of the add portion.

FWIW

What's the difference in Accolade and Ovation?

I remeber, I was in Tampa for the introduction of the Panamic, (junk lens,by the way) when the labs wouldn't warrant any comforts fit below 22mm. This was about the same time (2000) that frames got smaller, and more importantly to Compact came out as the first short corrider pal. Subsequent to Compacts popularity, the Panamic and the Comfort were now warranted to be fit at minimun seg height of 18 mm. We tried them, and of course when we layed them out the total add power was completely taken away. Essilor didn't want us to bump up the adds to make up for it though, because they said it would affect a design change, to which later I understood that by bumping the add that reduced the channel of good vision especially at the intermediate. Thank you for allowing me to revisit that whole situation back in the year 2000, lol

The minimum seg height for Natural is 18mm,

Some of us on Optiboard(Me!), have become jaded! See, there was a time when the minimum seg height for the Natural was...get this...22 or 24 mm!

Your describing the ultimate 360

Joshua,

Oh yeah.....22 or 24!

I would assume that the Ovation would give a much better reading area at 18 high than the Natural. I would assume that since the Natural was originally made for a 22 or 24 seg, that a majority of it would be cut off at 18 high. Although, there are some that would argue that that is OK. There argument is that if you have 85% or even 75% of the add that it is still ok. Don't get jaded like me!

It is nice to hear your refreshing newbie questions....keep them coming!

Absolutely True!!!
The Natural was made for a higher seg ht. The Natural is the sister lens to the comfort, and the ovation is the sister lens to the panamic.
I wear large and small frames depending on what I am doing. The natural has a slower progression and I think 22 is probably the lowest I would go before switching to an ovation.

The minimum seg height for Natural is 18mm, and for Ovation its 17mm. Say a customer OC height is 18mm, would Ovation at times still be better because it would allow a larger area of maximum reading power?

I am looking forward to your answers Mr. Chiling ;).
