Mark,

I haven't worn either lens but the ID should have a narrower intermediate on
both meridians because of its short corridor design, similar to the XS ILT.

I'm guessing that the Hoya lens would be about $100 more than the Multigressiv
ILT, if the ILT is priced similarly to the Multigressiv 2, which I haven't been
able to get since June '06.

"Rodenstock, the German manufacturer of ophthalmic lenses, has been acquired by
European private equity firm Bridgepoint from the current owner Permira, another
private equity."

The USA operation is owned by Optical Distributor Corp. I'm still trying to
product availability.

Just a guess, but it sounds like there's a cataract in the left eye.

Sorry, that can be really uncomfortable.

The old Rx is helpful, but knowing your corrected visual acuities would help to
convey how well you see, along with contrast sensitivity testing if applicable.

Back to your original question- what's the best PAL for general purpose use with
emphasis on the distance vision? Zeiss Gradal Top and Hoya ECP are two of the
best in this regard. If you are looking for the most refined lens, especially if
the add power can not be reduced, try the Impression (if your outside of the US
or ILT in the states), ID (this lens can be optimized for short near focal
lengths) or Zeiss Individual.

Alternatively, you might consider a segmented bifocal fit low, or single vision
distance glasses. Excellent distance vision and much less expensive than PALs.

Suggestion- have the doctor or optician show you the vision with a reduced add
power of about +2.25/+2.50. I think you'll find that adequate for what is
essentially a pair of driving glasses, and because you have separate readers and
computer glasses.

Use my recommendations as a starting point only. Trust your optician to steer
you in the right direction using their experience and by having much more
information about your history and visual requirements.

I have heard that Hoya ID has a wider intermediate area (at the expense of
reading and distance area) as compared to the Rodenstock ILT. Is that
correct?

Are these two about the same price?

Call the office who gave you the eye exam and ask for an updated Rx. They
are required by law to give it to you.

I'm sorry but the optician has the only copy of the new
prescription I'm talking about. However, I do have a
prescription from a year ago which would probably provide
some of the information:

DV
OD spherical plano , cylindrical +2.50, axis 85
OS spherical -0.75, cylindrical +3.25, axis 80

ADD
OD spherical +2.75
OS +3.00

I have one eye problem I know of: I've had a few accidents
over the years and have several abrasions on both corneas.
Periodically, these abrasions become irritated and
problematic. I'm supposed to use Muro 128 when they are
really irritated and lubricating drops such as Systaine
during the day. I still have problems at night and often
wake up with my eyes burning and irritated.

I apologize for not having a copy of the present
prescription - I foolishly went directly from the eye doctor
to the optometrist and didn't make a copy but I hope the
previous prescription can shed some light on the problem.

Thanks for your help.

Louise

The peripheral blur is probably due to the astigmatism, not the Varilux Comfort
design.

Do you mean the "add for reading/near" is +3.25? If so, that implies that there
are some medical problems with your eyes.

Increasing the add power will increase off-axis blur, general discomfort, and
decrease the field of vision at all distances. One might decide to keep the add
power in the +2.50 to +2.75 range, especially if you are using separate readers
for extended near tasks.

Shamir's Autograph lens might be a better option if the astigmatism is more than
three diopters. These types of designs incorporate atoric surfaces, increasing
the field of clearest vision when there is a considerable amount of astigmatism.

Well, that makes the choice of a +3.25 add extremely suspect for the everyday
glasses. Make sure you're comfortable reading at 12" if that's the power they
feel is necessary for the readers.

The first thing to consider is reducing the add power. That might be enough to
make any of the lenses that you've mentioned much more wearable. Either way, if
you want an increase in visual refinement and comfort, I'd consider Hoya's ID
and Rodenstock's Impression ILT designs.

Hope this helps,

Default How to choose a progressive lens?

I've been wearing progressives for many years and finally
ended up with the Varilux Comfort because I was able to
adjust to it. However, the poor peripheral vision
performance of the lens has made me look further now that I
have a new prescription.

I am highly astigmatic and the reading section of my lenses
has just been altered to +3.25

At first the reading was at +3 and I was given the Definity
lens. However, I got headaches and the eye doctor re-did
the prescription and moved the reading to 3.25. I could no
longer use the Definity lens.

Now the Shamir Creation is being recommended. I've looked
at the Shamir site and I don't fully understand how to
assess whether the Creation, or another kind, would be
better for me. I understand the central column, but I don't
understand the yellow and green sections that look like
footprints :-).

I use the glasses mostly for driving, movies, museums and
only for reading when I'm out in the world. I have a
separate pair of reading glasses for the house and a
separate pair of computer/office glasses.

How does the Shamir Creation compare to the Definity? Or
perhaps the better question, given that my lenses are around
$500 and I don't want to make a mistake, how do I figure out
what might be best for me?
