Nikon i versus other progressive lenses

**parimar** · 08-01-2004, 02:40 PM

I have worn Essilor's Comfort progressives for a number of years. This year I thought I'd like to try a smaller frame and "short corridor" progressives were suggested.

I should mention that I do a lot of computer work and do not like moving my head a lot to read either on screen or paper.

My new RX read:

OD sph: -8.50 cyl: +050 axis: 43 add: +255
OS sph: -8.50 cyl: +100 axis: 163 add:+225.

The beginning of a cataract was also noticed in my left eye.

Almost all opticians I visited suggested the Nikon i with the ICE coating.

I was fitted twice with the RX I listed above using the Nikon i and ICE coating. Once in a 1.6 index the other in a 1.67. Both times vision ito my right was great - left vision had me moving my head for focus and clarity in pheripheral vision and driving me crazy at a computer screen.

The optician who fitted the 1.67 index lenses suggested that I should get my RX re-checked. (1st RX was April 27, new RX Jul 13)

I did; the RX changed for the OS and now reads:
OS sph: -8.25 cyl: +050 axis: 150 add:+225

I was fitted for the third time again with the Nikon i and again the same problem ocurred - I'm constantly moving my head to compensate for poor pheripheral left vision

I am getting a bit frustrated by all this and am wondering if there is another lens that can be tried to improve my pheripheral left vision.

One optician did suggest the Essilor Panamic, but said it was the Nikon i in "disguise".

As a consumer I am totally confused and baffled by this new technology.

Any suggestions would be greatly apprecaited.

They actually told you that the Nikon i was the Varilux Panamic in disguise?

Those are completely different lenses.

I understand why you are confused. I would suggest either going into the Panamic (because that is the next step up on the Comfort), or I would suggest going back to the Comfort.

It can be a lot of factors, but to me it sounds like the Optician should check the measurements on the left eye. Do you mind telling me if you purchased the glasses from an Optician or an Optomitrist?

from an optician

Hmm, strange. Maybe get the Optician to put you back into the Comfort, because you know that you do not have problems with that lens, and hint to recheck the measurements. Of course no professional likes being told that their measurements are off.

Try using the Zeiss individual lens, it is the latest in progressive technology and it comes in 1.6 high index with Zeiss Carat AR coating.

Went back to the optician yesterday and I was told that all my concerns are "normal" and I should give more time to breaking in the Rx.

When I made a general inquiry about using another lens I received the response that "all lenses are basically the same", "try these for another week or two and if you're still not happy we can set you up with a recheck".

However, the optician did adjust the frame, so now I have more blurred vision when viewing a computer screen then I did before. :(

So I'll give it another week and ask for a refund and try another place.

Any suggestions for a knowledgeable optician in the Ottawa, Ontario Canada area?

parimar, the nikon i is not available in the US, so i'm not familiar with it, is it a "short corridor" design? did you get a too narrow frame? you said the OD was fine, it's just the OS bothering you? did the optician use monocular pds and monocular seg heights? a short corridor lens design in a 2.25 add in a shallow frame is going to cause some problems at the PC...you should have a nikon online PC lens design for working at the PC. comes in 1.67 Crizal, wonderful product...

The Nikon i is a lens with a 16 fitting height, but I think you hit the nail on the head with the monocular fittings. That was what I was thinking. I have found that one of the biggest adaption problems for PAL's is when the dispenser fits bioculary instead of monoculary. A lot of dispensers do not understand that if you move a couple of mm's out on a flat top or single vision lens there is usually no problem, but with a progressive it can make all of the difference in the world.

If you would have said that above mentioned sentence......................you should never have walkled out of the place with any type or brand of progressives.

You would have purchased glasses with a large segment straight top and would have clear vision to the right as well as to the left. Besides that a small frame with progressives is only good for fashion........and not professional use.

I agree with Chris, however something like a Nikon Online or a Zeiss Business lens should still be suitable. The ST bifocal would only work in a case like this if you change the top portion to include part of the add ie if add was +2.50, on a +1.00 rx ou, I would rx +2.50 to +2.75 on top depending on distance to computer screen and have ST seg have remainder of add either +1.00 or +0.75. this would be very easy to use but patient will need second pair for distance if distance correction is needed...you will have 2 sales...too bad:)

I also agree with Chris that small frames progressive use is for fashion. These short corridor permit rapid change from distance rx to near rx but the sacrificial lamb is the intermediate...I had an optician who was really stuck on small frames and short corridor lenses...never had so many come backs and unhappy customers...she only lasted 6 months with me. Px who want progressives in short frames need to be educated as to their down fall and if they do not do any computer work or have need for intermediate va and really want a small frame with short corridor lens, then they should do fine...if not, they probably will be too embarrassed to return and hear: "I told you so...":cheers:
