I've been trying to get a progressive for computer work - computer, down
to reading. I had one a long time ago but my prescription has changed. I
had an optometrist do the prescription and his optician chose the lens
etc.
I was told to use Zeiss lens as they have a wide field. I did so and used
the anti glare coating that comes with the Zeiss lens.
Now I am having trouble due to glare - a problem I don't have with my old
prescription - I believe they are Varilux Comfort. I have had a few
corneal abrasions (healed but not perfectly), and I have light eyes. I am
sensitive to glare and overly bright lights.
I visited my ophthalmologist asking for help and was told the following:
Zeiss uses a very light, and inadequate anti-glare coating and that is the
reason I'm having this problem. Essentially, therefore, I should not use
a Zeiss lens.
My ophthalmologist recommended Kodak Unique Progressive lens and the use
of Teflon Clear Coat for the anti glare. He said this would markedly
reduce my problems and that the lens is also superior.
Needless to say I've just spent a lot of money on lenses that aren't
working for me and the optometrist is saying there's nothing wrong, while
the ophthalmologist is saying the choice of lens, and particularly the
coating that goes with it, will not work for me.
I would greatly appreciate your thoughts and experiences both the the
Zeiss anti glare coating and with the new Kodak Unique Progressives with
Teflon Clear Coat.
My prescription for the computer glasses:
DV
OD +2.25 +2.50 80
OS +0.75 +3.50 80
ADD
OD +1.00
OS +1.25
Thanks in advance.

First, if you have polished edges, that is most likely the problem. AR
coating will not solve this. This is a common mistake made by opticians,
especially when they get a few extra bucks for the polished edges.
Zeiss has several different AR coats available (not including the ones with
a reflective coating in addition to AR coat).
- Teflon Clear Coat - This is available on Zeiss branded lenses, including
the RD and Business (computer lenses)
- Carat Advantage - Premium Zeiss AR coat which I have on my Zeiss ID (very
satisfied with durability and effectiveness of this coating)
- Carat - Regular Zeiss AR coat
If you have the regular Carat AR coat, that "might" explain it. The premium
Zeiss coatings are excellent and durable.
The main advantage of Teflon Coated lenses is they are durable and easier to
clean than traditional AR coats, but the Carat Advantage is very good IMO
(not sure what the difference is).
AR coating was invented for use on camera lenses by Carl Zeiss Optics in
1935. I think your ophthalmologist is blowing smoke and/or has no idea what
he is talking about (they don't teach about lens products in medical school,
and even if they did, the products change rapidly).
Ask for a remake of your Zeiss lens with the Carat Advantage or Teflon Clear
Coat. Or ask for a refund. There is almost always a remake or money-back
warranty included with progressive lenses, which is one reason they cost so
much.
