jo - 19 May 2006 21:16 GMT
In Feb. 06 I went to have my eyes examined because age is making it
hard for me to see up close out of my glasses.  My glasses are for
distance.  I am 45 (well, ok almost 46) and have been wearing glasses
for distance since I was 23.  The eye exam showed that my distance
vision had improved some and that my close up vision wasn't what it
used to be.  I've been looking under my glasses or taking them off to
see printed material.  I usually only wear my glasses to shop, go to
mass, and drive.  I had never been to this OD b/4 but he was covered on
my insurance.  I was going to get my rx filled where I used to but
decided get them at the OD office (eye doc and eyeglass place in one).
The girls in the office talked me into getting progressive.  I had
great reservations but after two weeks decided to get them.

They were awful.  I could only see clearly out of a small portion of
the glasses and driving was a nightmare.  Peripheral vision was
sickening.  I went back.  They said they would exchange them for a
single or bifocal.  I went w/the bifocal.  Upclose was fine.  Distance,
however, was off.  I called them after two weeks and the girl said I
just needed to get used to them.  I was still wearing my old
prescrption sunglasses.  I gave it more time but nothing changed.

I went back for another eye exam.  He said my eyes were dry and to use
artifical tears for 2 weeks then come back.  If nothing had changed, he
would write a new rx.  During the next week I noticed that when I
looked directly through the glasses that things were just not clear but
when I looked through them across my nose (head turned right) that
things became sharp.  I went back and told the doc.  He said I was
creating a myopia.  He did his checking with the machine lenses stuff
and wrote a new prescription.  Things at 20/20 seem good, it was the
distance stuff - like reading the grocery store signs, speed limit
signs, road signs, etc that were not sharp).

The girl at the front office said this was the last change they would
make.  They were going to charge me for a new rx, but being the vocal
person I am said no way.  I have had the new glasses for about 3 weeks.
I am having the same problem as before, not quite sharp in the center
but if I turn my head to the right it is much better.  It is not as bad
as the first rx the doc wrote but I am not satisfied.  I have paid $175
out of pocket for the lenses.  I made an appt. w a new doc for next
week.  I will have to pay the cost of the exam myself but for some
reason the first doc's office never submitted the lens/frame stuff to
the insurance co.  So as of right now, I can still get new lenses.  It
will still cost me about $80 for the crizal coating plus the exam.

Sorry this is so long but I am in need of advice.  What is causing me
to see less sharply out of the center of these glasses?  Does the fact
that they are bifocals have anything to do w/it?  The bifocal part is
extremely annoying and if I end up getting new lenses, I will get
single distance and continue to look under my glasses for close up
stuff.  If the new doc says the rx is correct, could the manufacturer
have messed them up?  What should I do w/regards to the $175 I am out
from the old doc?  If I call them now, they will realize they did not
submit the claim for the lenses and frames and will do so, causing me
to have to pay out of pocket for any new lenses I may need.  My
insurance will only cover exams/frames/lenses every two years.  Why
can't I see right out of these glasses?

Thanks for any help/advice/experience anyone can give.

What is your pescription? What you can do is read something as far away
as possible with your single vision lens then do the same with the
bifocals. Progressives may take some time to get used to, the upper
half is for distance and the lower half for near, you need to look at
the right segment for maximal clarity. Took my dad a week to get used
to his plus progressives, ditto to my mom for her minus progressives.
Taking your glasses off for near is another solution, something one of
the old lady I know in person does. Another old lady just doesnt bother
wearing distance glasses except sometimes to drive and shes between -1
and -1.5

Shhhhh.  She'll be okay.  Don't take it so personally.  She'll simply
get MUCH better advice from any of the OD's on this board than from
you or Otis.

Easy there, Ace.  It'll all be alright.  No need to get so snippy

You stated your case.  Once the doc's weigh in, she'll do what she
thinks is best.

Ace only advises. Ace doesn't see the need to read the

or better).

I don't think that is quite fair.  Otis' advice for considering Zenni is golden.
But not for "progressives".  Of course, you need a competent script to
start.  Good luck on that.

One theory is that the eye-care professionals have learned that they get
a lot of repeat business attributable to the vagaries of contact lenses,
"aspherics", "progressives", eye potions and solutions, etc., and therefore
vagarize scripts for simple eyeglasses.

One possibility is to check a new script with a $19 single-vision pair --
those should be good for signs and distance detail during night driving.
If good, you can go on to Zenni bifocals, or near-vision glasses, if needed.
If not, heave a brick through the f.cker's store-front, and find another
script writer.

>creating a myopia.

I'm wondering how a person might "create a myopia", honestly.  I
developed mine, I didn't set out one day to acquire short vision :P

It sounds as if the optical centers of the lenses aren't in the
correct place.  I'm going to guess that your pupillary distance
(distance between pupil centers plus displacement up/down/left/right)
wasn't measured at the shop.

Lacking measurements the dispensing optician will oftentimes put the
OC in the center of the frames.  If the frames are too big or too
small for your face (ie, your pupils aren't centered in the frames)
then the OC will be incorrectly placed for you.  Likewise if you were
mismeasured the same problem will happen.

So, if you weren't measured that'll explain the problem.  Go to a
different optician and ask for the OC of the spectacles to be located,
then ask the optician to measure you.  Take the information back to
the dispensing optician and smack 'em upside the head with it, then
demand a refund and take your business elsewhere.  Hopefully you paid
with a credit card, hopefully you're documenting every visit and every
conversation with every person you speak with at the shop so that you
can dispute the charge with your card issuer and make it stick in the
event the shop decides to dig in its heels.

If you happen to have an add for astigmatism you should be able to
locate the OC yourself: hold the spectacles up to a checked surface,
when the meeting point of four squares present 90-degree angles that's
the OC.  I'm not sure if this trick works for spherical Rxs or not.

Disclaimer: I am not an optician, an optometrist or an
ophthalmologist.  I have been wearing glasses for nearly forty years
so I think I know a thing or three about how they work and how they
ought to fit.

jo - 20 May 2006 01:00 GMT
Wooly,

Thanks for the info.  I do believe they measured me.  They had me place
my chin on a rest and look through a machine.  The office girl did
this, not the doc.  She then focused the machine and took a
measurement.  She also measured the rx in the glasses.  He did all the
measuring w/the different lenses in the office.  I don't think I have
astigmatism because I am assuming he would have told me.  But after my
experience, maybe not!

I thought it was odd when he said I was "creating a myopia".  He said
that the prescription wasn't strong enough and that I was increasing
the strength by looking through the far sides.  I tried doing this with
my old prescription and it is all completely the same.  If anything, it
gets slightly blurry when I look out the edges.  The ONLY reason I even
went to the eye doc was because I was tired of looking under my glasses
and thought maybe bifocals would help.  Ok, I also hated my frames :)
If it hadn't been for that, I wouldn't have gone.  I'm not having any
problem w/my current glasses.  The doc said my rx had changed a little,
the girl in the office said it changed a lot.   ????

When I originally got the progressive (aside from maybe being someone
who could not adjust to them) of course I couldn't see well out of them
because the first prescription was wrong!  I asked the office girl if
they just re-do the progressive lenses and she said that they make a
whole new pair because progressives are made differently.  But since I
am still having the exact same problem w/the bifocals, I am wondering
if they didn't just use the same b-focal lens and just re-do them
(don't even know if this is possible).

I've been wearing glasses for about 25 years and this whole experience
is a first.  They also took pictures of the insides of my eyes, even
though I signed a form saying I didn't want this.  Since it was a new
doc, I thought that the pictures he took were something that was part
of their particular routine.  After talking to the people at the place
where I had gone in the past, I learned that they have gotten many
patients from the other doc with all the same complaints. The people at
the old place said that if a customer/patient just wasn't happy w/their
glasses then they would be returned, including the insurance part, so
they could go somewhere else.  At the new doc, on the bottom of the
receipt, it says that all custom glasses and contacts sales are final.
Well duh, of course glasses and contacts are custom but if something is
wrong they should fix it, no matter how long it takes.  At one point,
when I was deciding about the bifocals after the progressives the girl
said she wasn't sure if the bifocal would fit in the frame.  I said I
would pick out another frame -- she said no, that sale was final.  Yes,
red flags were going off in my head but I still thought they would fix
the problem.

Yes, I did pay for everything via credit card, which I promptly paid
off!  This was two months ago and I don't think I can do anything about
that money now.

I will ask the doc next week about the measurements, as you posted.  I
don't know my prescription (since I had them do the glasses, I didn't
ask for a copy).  Can I get it off the glasses myself?  Thanks for your
help.  

Jo
Wooly - 20 May 2006 03:32 GMT
Sure sounds like you've got a QUACK, which is unfortunate.  Go in,
speak rationally, give them an opportunity to refund your money.  If
they won't make you happy tell them you'll file a complaint with your
insurance provider, with your credit card issuer, and with the state
board of optometry in your state.  Any one of those threats ought to
get their attention, the prospect of all three organizations landing
on them at once ought to make them fall all over themselves to make
things right.

Make noise about small claims court too.  Hell, make noise about a
class-action suit of some sort if you can get the old place to hook
you up with the unhappy refugees.

And be prepared to spend more money at the old place to have correct
spectacles made.

All makes sense so far.

Sounds like a problem either with centration (alignment) of the
progressive lenses (more likely), or maybe with adaptation (less likely)
or a combination of both.

Distance vision in a bifocal should be clear pretty well straight away.
After two weeks there's no more 'getting used to them'.

It's true that dry eyes can cause vision to fluctuate and be hazy but
your description of your problems doesn't seem to match this as a cause.
Did the artificial tears help you see more clearly? If not, then dry eye
wasn't the cause of your problem.

 During the next week I noticed that when I

This indicates that the centres of the bifocal lenses are not aligned
with your eyes. It also suggests that your lens material may be
polycarbonate plastic or some other lower quality optical material
(google 'abbe value') - but this second point is a guess on my part.

 I went back and told the doc.  He said I was
> creating a myopia.  

He meant that when you look through a lens off-centre, distortions
inherent in the lens create a different focus - usually detrimental but
in your case advantageous due to the fact that the central focus isn't
right to begin with.

Sounds like she is blindly following company policy but she isn't
realising that you have had a genuine problem right from the start and
you're not trying to take advantage of them.

They were going to charge you? Unbelievable. Don't they have any kind of
warranty, or after sales service?

 I have had the new glasses for about 3 weeks.

Combination of either (1) wrong Rx to begin with, (2) polycarbonate or
high index material, and/or (3) mis-alignment of the optical centres of
the lenses.

 Does the fact
> that they are bifocals have anything to do w/it?

Probably not - bifocals are pretty straightforward to manufacture and
get used to, especially compared to progressives.

 The bifocal part is

Getting single vision lenses and looking underneath them is always an
option, but progressives are the ultimate solution to give you the most
versatile vision (and of course they have no annoying line). However
progressives must be made precisely and are not forgiving of any error
in the measuring and manufacturing process. I ALWAYS recommend
progressive to my patients (rather than bifocals) because I know my
staff have the expertise to make them accurately. If they're not made
accurately then you'll experience narrow zones of clear vision.

By the way, if you are a computer user, forget bifocals, progressives
are better (or take them off).

Well yes but the other doctor's office should have detected this in
their routine checking and rejected the lenses before they were ever
given to you. In theory.

Best to ask your new doc after you've worked out what the original
problem is. But to me the glasses don't do the job you bought them for
so that's surely grounds for a refund.

It sounds like you picked the wrong eye doctor! Please don't be put off
progressives (or bifocals) as they can be very useful; it sounds like
your problem is with the eye doctor and his office rather than the type
of lenses. The moral of the story is to go to the place you trust rather
than the place that's cheapest!

PS: Please take the advice of both Otis & Aceman with a grain of salt -
they probably mean well but are full of misinformation & half-truths.

jo - 20 May 2006 16:48 GMT
Dom,

Thanks so much for the info you gave me.  I think I am going to go to
the new eye doc (I've been to them b/4) and see what he says about the
rx.  I will decide what to do w/the old doc after I know if I need new
lenses.  Either way, I will be in contact w/the old doc.  At the least
I feel they should refund my out of pocket expenses.  If I end up
needing new lenses, I will get the old ones and return them and ask for
a refund.  I doubt they will give me one because on the bottom of the
receipt it says that all custom eye glasses and contact sales are
final.

I don't want to go back to this doc because I've been there three
times.  He wants nothing to do w/the office end of things.  I don't
necessarily think the problem is the doc, but rather the office people
and the manufacturer.  At one point I asked the office girl of they
could have made a mistake in making them and she flippantly said not
possible.  My impression is that the office girls (I think one of them
is married to the doc) are SALES people first and foremost.  My husband
had his eyes checked there as well.  He doesn't wear glasses but like
me, the up close stuff isn't as clear.  The doc said over the counter
reading glasses w/be fine for now but the office girl tried to talk him
into progressives!!  I wish I had just paid out of pocket for an exam
at the old place to begin with and had gotten my glasses there too.

Unfortunately, I am very put off by the progressives.  My sister-in-law
has them and says she can only see out of one specific place on her
glasses.  Everything else is off.  Maybe in a few years when I get my
eyes checked again (at the old, trustworthy, competent place!!) I will
consider progressives.  As for now, if I need new lenses I am going to
get a single, distance lens and just look under them if needed.  Where
I need them the most is grocery shopping or mass -- looking distance
then at a list or music.  I wear rx sunglasses about 90% of the time.
They are the best.  I don't know how people can drive w/out
sunglasses!!  As for tv, being at home and stuff I don't wear them; I
never have.  Sometimes it's nice that things are quite clear -- then
you can't see how messy the house really is!!

Thanks again for everyone's help.  I will let you know what happens.
As for now, I'll just use my old glasses.

Nope!  Depth of field and residual accomodative amplitude favor single-
vision eyeglasses for computer use (Zenni's are good).

Only a very small portion of "progressive" lenses is right for the computer,
or other desk work.  With the single-vision close-work eyeglasses you can
see anything on your desk, including the computer display, no matter how
you hold your head.  Well, if you are totally presbyopic, and require a huge
36" display on the other end of your huge mahogony desk, you might need
bifocals with add+1 uppers and add+2 downers, but with those you could
also see what the crowd at the bubbler is up to, and, in a pinch, drive by day.

Actually, bifocals for computer use are a bad idea, because you have to hold
your head at an unnatural angle.  Same, no doubt, for "progressives", though I
cannot speak from personal experience about that.  My lady has several pairs
of "progressives" that she does not use, but she does not tell me exactly why.

Dicky,

It's funny you should comment about progressives and computers.  The
sales girl at the glass place kept pushing the progressives on me
because they have the intermediate field for computers.  She kept
telling me this over and over, despite the fact that I told her no less
than 6 times I don't need any glasses for the computer and that I don't
wear glasses at home.  That wasn't the reason I tried the progressive.
I was concerned about the line in the bifocal interferring w/my vision
- and it does - but am very leery about trying the progressvie again
due to my experience.  While I think the idea of progressive lenses is
great, I don't like having to hold my head or turn my head just so in
order to see out of the relatively small viewing field.  I'm more
comfortable turning my eyes instead.  Of course, if I had the right rx
w/the right progresssive and just got used to them, I'm sure I'd like
them just fine.

Ordinary single-vision reading glasses can be quite good for
computers as well as for reading*, for folks who need them.
You should bake a special pie for the girl at the glass place.

If you had some ham, you could have a fine ham sandwich,

Dicky and I like single vision glasses.  Most older people don't.  It's
a personal preference thing.

Speak for yourself.  I don't like eyeglasses or any other kind of eye
prosthesis, intervention, or eye guk.  However, given  human condition
and the situation with human eyes, I feel that some choices are more
reasonable than others.

With regard to "older people", they, in general, like most everybody else,
don't have the slightest friggin' idea how their eyes work, or don't work,
and can be baffled and buffaloed by most any smooth-talking operator
with a fancy, expensive, high-margin, often-hazardous, solution to the
simplest of their visual problems.

Regarding the adaptation of presbyopic eyes to close work, like reading
and computer-screen viewing, I feel entirely competent (though neither
OD nor MD), to shout from the housetops that reading glasses are the
simplest, cheapest, and most obvious solution.

I think it's obvious that *no* glasses are best.  My comment was simply
meant to convey that if you *have* to wear glasses, most people with
presbyopia prefer multifocal glasses.

> With regard to "older people"

"Older people" is a code phrase for "presbyopia".

Works for me.  Works for you.  Of course, we both have IOLs due to
cataract.  Not everybody does.  For a presbyope with myopia or
hyperopia, reading glasses may not do the trick.

My wife could use reading glasses, but she doesn't want to be carrying
around multiple pairs of glasses and swapping them in and out.  So she
wears progressives.

It's kind of funny, really.  For 35 years, I wore glasses almost every
waking moment.  My wife didn't wear glasses at all.  Now, she puts on
her glasses when she gets up and doesn't take them off until she goes
back to bed.  I don't normally wear glasses anymore, due to the IOLs.  I
only wear them for close work.

This is why some of us work hard to create an experience that dissuades
patients from seeing "...the doctor on my insurance plan."  It appears
the patient education and the post-sale service were lacking.  Don't
write off progressives, yet.  If your first car was a lemon, would you
stop driving?  Your visual needs may require a reconsideration in the
future.

My wife, Mrs. Adams, has a couple of expensive eyeglass pairs that she
does not use.  I thought they were progressives, but it turns out that one
pair are simple reading glasses she got for computer use.

Here are the details -- see if you can make any sense:

Here basic script is
+3.75
+3.75
Add 2.0

The script for "computer glasses" is:
+6.00
+6.00

She is an proud person who has a large computer display screen which
sits a bit beyond her reach on a huge fancy table.

I asked her about the examination for the "computer glasses" and she said
the "doctor*" repeatedly and rapidly asked "which is best, this or this", and
she got confused.

I have tried to explain to her, from 8th-grade general science, about how
focal length is inversely related to lens power, and about how a one-diopter
lens is one with a focal length of one meter, and how one inch is equivalent
to 2.54 centimeters, but she did not take that course, and inversity is
offensive to her.  So we never even got so far as the significance "add number",
which I have been told by some "doctors*" is a subjective thing, anyway.

So, like your wife, Mrs. Adams prefers the same pair of eyeglasses for all
tasks, which eyeglasses happen to be "add 2.0" bifocals.  Though she needs to
sit before the computer with her head at an awkward angle, she says the
bifocals give her a less blurry image of the computer screen than do the
computer glasses (which actually have much fancier frames).

My dinky little CRT screen sits at 20 inches from my face, and my "add 2.0"
(Zenni) reading glasses work quite perfectly, for that, and most everything on
my desk, which is actually quite narrow.  In a pinch, I can use Walgreens
readers, but that is a matter of dumb luck because my implant surgeon was
having good days when he did me.  Also, for that reason, I can see everything
else in the room quite sharply by peering over my narrow readers.

flip-floppers are mostly home-grown techs.  Neither of two excellent phoropter jockeys
I have known were doctors of any sort, and the absolute worst one was.  (That
was the one who prescribed "add 2.0" for one eye, and "add 1.5" for the other.)
