what lens and what coating for difficult computer progressive

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.

 

I don't know your exact situation, but I found this article very
interesting.
http://www.lightenergysource.com/ScotopicTechnical.htm
The article discusses different light frequencies (temperatures) and how
by using
a higher temp light you can use less intensity and still perceive the same
brightness,
However the higher temp light is received by the rods in the eye and causes
your pupil
to close down. When your pupil is closed down you have less glare within the
eye and less
external light to cause the glare.
I'm not sure I explained it well or correctly, read the article and try
making some changes
around you computer.
Hope this helps, Mike
