I have a customer had NIKON GO for years and I dispensed a new PAL, which is ACCOLADE FREEDOM. However he ended up coming back saying he feels swim effect of wearing the new PAL comparing to his old NIKON GO. His Rx has mild change; SPH -0.25 and the ADD +0.25 OU increased comparing his previous RX. I know I have to remake his PAL, but which one PAL having similar design with NIKON GO getting less swim effect; Varilux Comfort, Panamic, or it is better to dispense the same PAL lenses, NIKON GO.
wasn't the Go based on a really wide distance area? I bet Panamic will do fine then
The customer complained he feels the swim effect very bad on the Accolade Freedom lenses, Index 1.58. He compared the lenses I dispensed to him and his old lenses, Nikon GO, Index 1.50 in front of me and he said he doesn't feel any kind of distortion on his old lenses. He could not adapt to Accolade and returned to me. I hope I could dispense a similar PAL lenses from Essilor to him to reduce my lose of the cost. If there is no similar design of PAL lenses from Essilor compare to Nikon GO, then I have no choice to dispense to him with Nikon Go PAL lenses.
Nikon lens design is typical very soft design with a narrow distance vision. If you normally works with Essilor I guess you should go with the panamic that is very soft as well. This will probably work the same way as the Nikon. Other soft designs with smaller distance vision could be Hoya ID.Originally Posted by lichou
Zeiss, Rodenstock, Essilor and Shamir use a tad more distortion because these manufacturers prefer a wider distance and reading area. (Excluding the Panamic with the softer design).

It looks for me that Nikon Go is one of the beginner progressive, with only a tad of addition. All normal progressive will have more distortion if you increase the addition. Essilor and Hoya are making these "prespiopy single vision lenses" as well, but if you change to normal progressive lens design, you will get more distortion. Tell your client this, and change then to Panamic if he needs the extra addition.

Keep your client in Nikon. If you need a lower fitting hight go to the nikon i or w design. The swim your client gets will not be there in any of the nikon designs. If your client is price conscious, consider the new nikon move, or move short(digital economy lens designs with minimum fit hights of 18 and 16). We never switch clients out of Nikon if they are wearing it.
There are so many factors one needs to consider when we dispense PAL. I remember Darry said once of having 95% success rate fitting 100 customers with adapter; I trully belive that. switched a customer from NIkon W ( the digital LOL) to comfort he was happy and brought his wife to buy another pair.
obviously your lab is an essilor lab and the comfort is a real bargain...LOL
It seems the Panamic from Essilor and the Nikon Go are similar design, which is soft design; The advantage of the soft design are: wider, longer intermediate corridor, smoother transition from distance to near, less swim effect, less tendency to curve straight lines, and requires less head turning. :cheers:
I got a lesson for this time, and I think I might not recommend customers to change the brand, and model that they are current PAL to another PAL due to price issues in the future.
Thanks for so much help from everyone.
Don´t be afraid of changing brand. We are all doing that every day. I think what your customer are missing, is the information about the issues when you are changing from a "progressive" single lens (a first time beginner lens with a tad of addition) to a traditional progressive lens with a lot more distortion. I think many opticians will fall in that trap in the future as these new progressive single vision lenses gets more popular.

Actually comfort is not cheap for us, we don't do that many of that(it is not worth it value/price wise), at the end of the day we don't go by the NAME, we know which lens is good on what from studies and other people and our own experience so we don't limit ourself to one lens.
I agree with OCP that it has alot to do with communication.
Is any way to get more specific information of soft design, hard design, contour map of lens by its name? So, we can pick up the right PAL for filling the requirement of or communicating with our customers. The detail information of PAL from the pamphlet of its company seems not very much provided.
I can't believe anyone would still recommend the Panamic over the newer designs. I wore the Panamic for a year but was thrilled to switch to the Physio. i also hear that the Panamic will be phased out.
From the previous discussions, It shows the Panamic is classified to the PAL of soft design. If the physio provides the less swim effect comparing to the Panamic, then what are the reasons. As some common pricipals, companies make some similar products in designs, functions, etc., matching their competitors.
Physio and Physio 360 are going to be really similar to the accolade/accolade freedom.
The result came out ..
I did redo for the px changing the lenses to Panamic, Essilor. The px came to pick up his glasses, and he feels the lenses almost the same as his previous one, Nikon Go. He said he can feel the unswimed effect of Panamic right way, as he felt the uncomfort feeling(swim effect) of Accolade, which caused him hard to adapt. Thanks for all of you helping me to solve my question.:cheers:
