The Definity may be a better choice if you do much computer work because
it has a very smooth and extended intermediate zone. There is little
sense of narrowness and not much need to practise with viewing angle.

Just picked up mine today. I've never worn progressives.
It's going to take some practice/acclimation. Apparently
the lab didn't do so well attaching the drilled frame and
they're crooked. Left side is lower than the right. That can
be adjusted. The problem is the left side also sits out further
from my face than the right. Additionally I didn't want the edges
polished so they put a "satin" finish on them? Still a good
amount of reflection off the bottom. I was expecting them to
look like the edges had been etched. Doc is going to have
them remade but I'm going to wear them for a week first to
see if I want to make any changes to the script.

I forgot what it was but basically around .75 with a 2.0 add?
I do a lot of computer work. I like my translating trifocal RGPs.
Doc advised against progressives (and the translating trifocals
for that matter) because of the heavy computer use. It's what
I wanted for spectacles as an alternative to my contacts.

1.67?, Crizal Alize, Transitions (whatever the latest version is).

Distance:
Seems like the distance area goes all the way across.
A bit odd is that the very top is not as sharp as the rest
of the distance area. Maybe a bit less than the top 1/8
of the lens. It doesn't seen like the script changes moving
into that area but it just doesn't seem as sharp.
Intermediate:
The intermediate area is narrow. But I don't have anything/
experience to compare with. I think it will work for me for
the computer. practice, practice. At about 33" the intermediate
zone is about 6" wide. Things are readable outside of that
but that's about where I start to notice the blur. I was expecting
it to be wider vertically too. I think I have a slightly taller
intermediate area with my contacts... maybe not.
Near:
Near at about 10" is about 4" wide, so much better (but I don't do
a lot of near work).

I've been wearing them for about 6 hours today and the "swimming"
effect is less when walking around. I'm surprised at the magnification
effect. Things are a noticeably larger through the lenses than without.
Haven't noticed this with the contacts but there's not much way to
do a with/without compare for that with contacts. I guess I knew that
was minimal with contacts being right on the eye. I think the oddest
effect is to see verticle line go \\ || // as you turn your head from
left
to right while looking at the same spot.

So far. I like them.

I started wearing the Definity lenses over a year ago after spending
many months learning about different progressives. I came from the
Comfort. I find the Definity extremely good. It has a much wider
channel than I have found in other progessives so there is no noticeable
periperheral distortion. The intermediate zone is extemely smooth and
wide. This makes computer work, which I do a great deal, very good. I
had anticipated needing a second pair of lenses for computer work, but
the Definity made that unnecessary. Johnson and Johnson sold Definity
to Essilor, the maker of the Comfort. I bought mine when they were
still made by J & J. I hope the manufacturing quality has not lesssened
now that Essilor owns them. They can't be ground by your local optical
shop. I don't know anything about the Physio that Bob Martello
recommended, but I can certainly give you a strong recommendation for
the Definity. Another professor at the university where I teach just
switched to Definity and he is also very pleased. To get the best out
of the smooth intermediate transition, you should get a fairly tall lens
and frame.

Physio 360 blows comforts away. Vision is much sharper in distance,
especially in the periphery and reading/intermediate is very good. I
have put about 15 unsuccessful MF wearers into Physio360 in the past 2
months, all with great success.

I haven't worn the Physio 360, but have tried other freeform back surface
designs, and have used Rodenstock's Multigressiv for about five years now,
although it is not optimized for position of wear like the 360. Very good lenses
for Rxs with more than two diopters of cylinder, especially if there is an
oblique axis. I would expect that the Physio will perform like the Panamac,
which is essentially a tweaked Comfort. These are very good general purpose
designs- medium length corridors, average peripheral blur in the distance,
average corridor widths.

Dana,

Distance field of vision is about the same, the intermediate is wider and
smoother with the Definity, the near zone is larger and comes into play lot
quicker with the Comfort. The Comfort will be a better lens if there is an
average or above average frequency of close tasks, and this is especially true
now that the add power is above +1.75.

Hope this helps,

Consider Varilux Physio360 then.

Does anyone have any experience with, or knowledge about, the Definity
progressive lens? A local optician recommended it to me to replace my
Varilux Comforts, and I'm curious about other opinions. I like the Comforts,
but would like less distortion on the sides even more.

My rx is -6.75 0 0 +2.00 add
-5.75 -.5 50 +2.00 add

Thanks in advance,
