Glasses for 5 year-old twins?

We have 5 year-old identical twins who will turn 6 next month.

The optometrist checked them 3 years ago and said they needed glasses,
but a second opinion from 2 child opthamologists said they could do
without glasses.

They were just checked again by the same optometrist who said they are
both far-sighted with a weaker right eye and wrote a prescription for
something in the range of -1.75.

I noticed that they could both read the tiniest paragraph on the
cardboard sheet as well as identify the smallest pictures, so they can
obviously compensate (one of the benefits of being so young) and that
the glasses would mostly be to relieve the strain.  Not having glasses
would not harm their eyes.

I'm a bit reluctant to have them start wearing glasses and will probably
get a second opinion again.

What's the general consensus re: fitting them with corrective eyewear at
this age when they can obviously compensate and don't seem to complain
of headaches, sore eyes etc?  They will be starting grade 1 soon, but I
don't imagine that they'll have too much difficulty seeing the board
since they are far-sighted.

Do optometrists look at this situation differently than opthomologists?

Thanks in advance.

Dear Pat,

It is always wise to obtain the second-opinion.  Then you can decide
youself.

This statement is not consistent:

Pat>  They were just checked again by the same optometrist who said
they are
both far-sighted with a weaker right eye and wrote a prescription for
something in the range of -1.75.

Otis> In general a "farsighed" person will require a POSITIVE value,
say +1.75 diopters.  A "nearsighed" child will have some blur
at distance, and will required a -1.75 diopter lens.  Perhaps
you could obtain a clarification.

Best,

Otis

I agree with Otis on the disparity between the prescription numeric value
(-1.75) and the diagnosis of "farsighted." You do not need to be a rocket
scientist or health care professional to know that. The fact that they do
see the smallest pictures would be an indication to me that they are
near-sighted. With further testing there should be no doubt.

Your more profound question is more difficult to answer. Should the twins be
fitted with prescription glasses? If you read this newsgroup over the years,
you would know that any answer to that question is controversial. It seems
to me, that the almost party line response from the professionals is yes but
a small proportion is wavering toward no. Otis and I, who are not vision
professionals, probably would lean toward no.

With twins, you might be in a position to do an experiment. Give one
corrective glasses as proposed by your optometrist. The other would not get
glasses or get bifocals to be used for reading but with no power for distant
vision. As a parent, you obviously want the best for your kids. The trouble
is, as you already point out, you do not know what that is.

With hindsight, I would consult a vision specialist to find out if not
getting glasses will do actual harm to your twins. My guess is that they
will say no, but that it would make it tough to do well in school because
they cannot see the blackboard well. Then I would give one twin the glasses
and not the other. In a year or two you can fit both with glasses if
necessary.

Good Luck!

I think both of you are misguided; the original poster likely got the
sign incorrect and meant +175 and not -175.  Both of you guys
should be jumping up and down that the provider of these
twins are suggesting the holy grail of PLUS lenses and not
the evil twin of the MINUS lens (only  a fiend would prescribe
a minus lens).

Without knowing what the dry and possibly wet refraction
results, it would be pure speculation on whether the kids should
be wearing a correction or not but I guess you and Otis know more
about this than a lowly optometrist.

You are are attributing more to me than I wrote. I noted the the OP said
that his twins could accommodate to close work. If that truly is the case,
why would a main line optometrist suggest a +1.75D lens?

I once was a "rocket scientist," but it does not take one, or an MD or OD,
to ask such a question.

Age 5 is the age when most kids start school, when it's reasonable to
predict an increase in near work and grading based on performance at near.

Age 5 is late enough, beyond the period of emmetropization, when plus lenses
might interfere with the natural resolution of hyperopia.

Age 5 is old enough that we can usually get reasonable data using cover test
and cycloplegia. I don't believe either of those tests were mentioned, and
it's enough of a judgement call that I wouldn't vote without knowing the
results.

That said, it's usually tough to keep a kid in glasses at age 5. And twins?

One approach - get some +175 drugstore readers and let the kids show us how
much good they do. If either Mikey likes it, get them a "real" pair.

Pat Coghlan - 24 Aug 2006 03:28 GMT
I guess the /do no harm/ rule is the one we want to follow.

She explained that the opthamologists probably did not recommend
corrective lenses two years ago is that the visual demands of 3
year-olds are not that great (distance reading, detail work etc.).  Now
that they are headed into grade 1, these demands will increase.

I know that when I can't see or read something (I have a mild Rx for
astigmatism, something like 0.5), I can get either of the twins to read
it for me or tell me what it is, so they certainly can see fairly well.

It's frustrating to have to keep 2nd-guessing the OD though.  If we get
another opposing opinion, I think we're going to have to change
optometrists :-(

It could have been a +1.75 instead of -1.75.  She did mention that the
eyeball was shorter, while someone who is short-sighted (myopia) has an
eyeball that is longer.

It sounds like they are hyperopic and +1.75 is fortunately not a huge
amount of that, so the Rx probably is pretty optional at this point.  As
a result, you will get a wide spectrum of answers, none of which will
probably harm or help the kids all that much, but nobody knows for sure.
 Having said that, if they were my kids, I'd probably go with the Rx,
at least part time (reading, tv, etc).

If they were +3.00 or more, I'd say it was probably not optional and
witholding the Rx could be damaging.  If it were over +4.00 I'd call the
cops if you didn't give them the Rx.

If the twins could do close work as indicated by their dad, that means that
they could get accommodation of 1.75 + 3 = 4.75D presuming they viewed
pictures at 33cm. Is that a reasonable amount even for young eyes? I am not
the vision pro.

What harm occurs when a strong positive lens is used for young eyes? That is
other than just bumping into things.

5 year olds have great accomodation. Even if they were +3 or +4 they
wouldnt need glasses *unless* it was for amblyopia controll if one eye
was significently weaker and started getting lazy. I doubt they would
wear glasses when it would make *no* difference in their vision! I for
one would never wear glasses if I could see perfect without! Just give
them eye exams annually and make_sure_that their refractive state does
not fall into the negetive. When they fall down to +.5 it may be time
to take action with a plus lens(with prisms if neccessary) for near
work to prevent a negetive refractive state.

Do you see any potential harm in placing all of that effort on a young
accommodative mechanism?

Do you understand the near vision triad?

Can you explain accommodative esotropia or esophoria?

Could you please explain how it comes in to play here ... if it does at
all.

In light of your answers to the above, can you please explain your
rationale for giving the above advice, and ... on what basis you
provide it?

Thanks, Ace.  You're always annoying ... and quite often dangerous.
Good to see =that= hasn't changed.

Sure they *can* accommodate that much, but it causes esophoria and often
esotropia, the former of which is usually uncomfortable for the child
and the latter of which is always harmful to the child.  Ace, Otis, et
alia always view the human vision system one dimensionally, as if
binocularity was of no importance.  Ignorance is bliss.

otisbrown@pa.net - 24 Aug 2006 19:52 GMT
Dear Pat,

If the optometrist said "too short", then the refractive STATE is
positive.

The refractive state of the young, normal eye runs between
zero to +2 diotpers -- in the young.

It is difficult to call refractive STATES in this range a "problem".

Their Snellen is most probably normal for age 5 -- about
20/30.  (Worth your own checking).

Perhaps you could get this majority-opinion optometrist
to explain EXACTLY why he thinks these children
should be wearing a "plus" lens at this point
in their life.

I would suggest the second-opinion, which was
previously suggested to you -- to keep a
lens off their face until they have more time
to develop.

It is good that you understand these two
contradictory, or second-opinions.  It allows you
to make a choice in this matter.

Best,

Otis

I asked her if the primary purpose for getting them corrective lenses
was to relieve strain and her reply was yes.

She also said one of the twins' right eye was a 'bit lazy', but she was
so all over the map that I'm definitely going to get an opinion from the
opthamologist they saw two years ago.  If he again recommends against
any correction at this stage, it's time to find a new OD.

Dear Pat,

If the ophthamologist recommends that a child with a refractive STATE
of +1.75 diopters NOT wear a plus lens -- I would consider this
a vaid second-opinion and NOT put the child into a strong
plus at age 5.

There is indeed a "secondary" effect to a +1.75 diopter lens worn
all the time, and that is that the refractive STATE of the child
will move in a strong positive direction.  And that
is what the ophthamologist would wish to avoid
for your twins.

There are STRONG OPINIONS about this issue -- and
you will have to sort them out to the best of your ability.

Ace - 25 Aug 2006 07:00 GMT
Otis is right, plus at this point will be overkill, not only will it
prevent myopia, it will leave them with too much hyperopia which will
cause big problems in the future as they lose their accomodation and
end up in bifocals. Let them undergo emmetropization, they shouldnt be
+1.75 as they get older due to emmetropization. Otis has said its
normal for young people to have this much positive refractive state
which will go down to about +.5 several years from now and to plano
somewhere in high school. Thats where they may want to use plus glasses
for reading to avoid inducing a negetive refractive state.

In all my years of practice, I've never ever heard an optometrist, an
ophthalmologist, or any scientist in the field agree with that
statement, and I've never seen it happen to any of the hundreds kids
I've prescribed plus for.  You and ace are misleading inoccent people in
a harmful way.  Your incessant b.s. on myopia development is at least
not as potentially harmful as the above advice.

w.stacy, o.d.
otisbrown@pa.net - 25 Aug 2006 15:32 GMT
Dear Pat,

As I said -- you will encounter strong opinions about
a child's refractive STATE of +1.75 diotpers.

There seems to be no overt problem -- that the OD
could articulate.

I would agree with the ophthamologist -- in his recommendation
that no plus be applied at this point.

None of us will know of your choice -- and that is up to
you -- clearly.

Also, was the recommendation that the child
wear the +1.75 diopter all the time.

Or was it ONLY for reading.

You should ask the OD that quesiton -- and ask
why.

The OD suggested that they be worn most of the time, else they would be
tempted not to wear them since they can see okay without them.

Mike,

Please keep the subject -- on topic.

In case you forgot -- these are NOT COLLEGE KIDS.

They are 5 year-olds with normal refractive STATES of
+1.75 diopters.

The optometrists recommend NO PLUS AT THIS POINT -- and
you seem to insist that these twins wear a +1.75 diopter
16 hours a day, 7 days a week -- forever.

I personally think that is a bad idea -- for this SPECIFIC
situation -- as do two highly qualified medical doctors.

That is the issue for Pat to review.

Amblyopia, or lazy eye, is more prevalent in farsighted children in the
eye that is more farsighted.  I have seen amblyopia develop in children
with a difference of 1.00 diopter between the two eyes.  Lazy eye also
has a strong genetic basis.

Also, unless a cylcoplegic refraction has been performed (i.e. dilating
drops), it is quite possible that the 1.75 diopters of farsightedness
is an underestimation.

Obviously, if a child has a lazy eye, they will compensate by using the
good eye.  The key points are to (1) obtain an accurate assessment of
monocular visual acuity, and (2) an accurate refraction, i.e. with
cycloplegia.  This will help you decide if doing nothing is causing
more harm than doing something.

otisbrown@pa.net - 23 Aug 2006 21:03 GMT
Dear Pat,

As an engineer -- I prefer to do my own measurements and testing,
just to double check.

A competent person (medical, engineering, or science) should have
no problem with YOU doing the checking.

Just to make certain of your twin's Snellen reading, I would suggest
that the read a "easy" Snellen on my site:

www.myopiafree.com

This is the IVAC Snellen, and had "pictures" that the twins
can easily see.  If you inform your professional, I think
he will be positive with you doing these "at home" measurements.

There are ophthamologists who are very reluctant to put a
5 year-old into a minus.  That is the second-opinion on the
subject.

Further, as stated here, a percentage of 5 year-olds do not
have 20/20, but rather 20/30.

The DMV in most states is between 20/50 and 20/40 -- and
there is no reason to "rush" a child into a minus lens.

So these are issues you should consider.

Best,

Otis

Pat,

you opted not to listan to this optom 2 years ago, you choose not to
listen to them now. Why do we need to answer you? You will not listen
to us either. You want to hear what you want to hear, not what is
happening with your children.

Yes, optoms look at eyes differently to ophthals. We actually know more
when it comes to functional issues.

With their script, it may be advisable to get glasses for near work,
but I would like to see how their eyes function. The script should
reduce by 1/2 over the next 4-5 years, and glasses will make no
difference to the final Rx. They make a huge difference to how they go
with learning to read however.

dr grant
Pat Coghlan - 25 Aug 2006 15:35 GMT
I negelected to mention that they actually saw TWO opthamologists back
after the OD 2 years ago.  Both suggested not getting glasses for them.

I'm not *ignoring* the information from the optometrist.  I go to her
myself and she has me seeing very clearly :-)  However, my gut feeling
is that it's not as cut-and-dry when it comes to young children -
especially mine - that's why I'm also looking for input here.

Reading isn't a problem.  They've been able to read for about a year
now, and would be able to read this message :-)

I just want to make sure that I make the right decision to give them the
best possible outcome, which would include getting glasses for them if
there was a risk of one eye becoming lazy etc.

I didn't want to bring up the ethics issue, but ODs here in Ontario get
a small fee from the province for an eye exam and make most of their
money from the sale of prescription eyewear.  She seemed very anxious
for me to look at frames while we were in the office, but I'm not going
to be rushed into a decision.

I'm surprised at the number of barbs thrown in this discussion.  While
this may not be an *exact* science, but it is a science, isn't it???

Dear Pat,

    The refractive STATE of the eye will "move positive" if you
place a +1.75 diopter on it -- and wear it all the time.

    In this case the childs vision went from about +2.0 diopters
to +3.25 diopter in eight months.

    This is probably why the ophthamologist recommended that the
twins not wear the "plus" at this point.

    But that is why their must be a second-opinion -- and that
you have a choice in this matter.

   The "name calling" that goes on about your right to an informed,
competent second-opinion is NOT PROFESSIONAL.

    Best,

    Otis

    ++++++++++++++++++++++

    Hi I wrote on March 15 regarding my son.  Here is the link in
case is of any use, there were a lot of nice people helping me.

    http://groups.google.com/group/sci.med.vision/browse_thread/t
hread/a6...

    To make the story short:

    My four years old boy was diagnosed with strabismus and
amblyopia.  He started crossing (in) his right eye when he was
almost 4 years old.  The

    ophthalmologist prescribed glasses OD +2.25 (sphere) OS +1.75
(+0.25) and then advised us to patch him 2 hours a day, and do
some manual activities while patched.  We did this for 7 months,
the amblyopia is gone for now.    Both eyes are 20/30.

    The doctor has raised the prescription twice, so in 8 months
my son has needed 3 different prescriptions, why didn't the doctor
go all the way since day one?

    Anyway, my son has been wearing the last prescription, 3.25
in both eyes, for 5 days now and we noticed today, as he was
watching TV, that he still crosses his right eye.

    Is that that he may need a little more time to get used to
the new prescription, and then he won't cross?  Or this is just
wishful thinking, and he'll need surgery?

    And how useful will be vision therapy in his case?

    Thanks

The barbs are caused by one or two resident trolls who repeatedly substitute
imagination for science.

A broken clock is right twice a day, and that seems to be enough for Otis.

I want to point out that her own optometrists both opted NOT to
prescribe your sons glasses. I am not a doctor and have no say in this.
Otis isnt a doctor either and is marely explaining the eye from an
engineer's point, not a medical point. What Otis is saying is to listen
to your second opinion optometrist who said NO to glasses for your sons.

Not that Im a doctor or nowt, but, I can read this message too. But with
a pair of just weak reading glasses of about +.75 and an astigmatism
correction of -.50 in each eye, I can see even better.

The text it sharp, in focus, edges are no longer fuzzy.

They *may* be able to read, but they  will probably read better WITH
glasses.

You could do what I did, and just get a cheap pair made up and see if
the kids notice anything different. You don't have to make them keep
wearing the glasses!

Not a good situation. In the UK, you're under no obligation to buy
glasses from whoever did the eye test - well, maybe some of the smaller
independants do (though Im not saying they're all bad). Over here, we
have a chain called SpecSavers, who give you your Rx and I can then go
away and get them from somewhere else if I want.

You could find a different optician and see if the results agree if its
that important?

Actually, yo are ignoring the optoms advice as you haven't acted. The 2
ophthals are only saying they don't need glasses as the eyes are
straight and they can read the bottom line of the chart. They have
taken no readings on how your children's eyes perform up close, which,
to me, as a paediatric optom, is the major thing of importance here.

Au contrair mon petite. The ability to read and the capacity to sustain
the activity are 2 separate issues. One is the processing of visual
code, the other is the ability to contract a muscle for a lengthy
period of time. With a script of +1.75, your children have to do 50-60%
more work to get things clear up close than the kid sitting next to
them in class. Try putting a bag full of books on your back and walk
around with it on all day and see how you feel. The problems we get
from moderate levels of hyperopia are fatigue and avoidance, not blur
and can't read. Additionally, there is the issue of the script. +1.75
is not necessarily the full prescription. Thet may be +3.00 or +4.00
and the optom has only given a script of +1.75, which is what I would
do in the same circumstance.

You can't give them a lazy eye from glasses in this case, nor will they
develop one if they don't get them. This is not the issue for your
children. The correct script will enable the to get maximal
comprehension from the text they read, no glasses may well cause them
to not get as much information from the text, which can lead to poor
academic performance down the track. While I am not specifically
advocating glasses here, this is the area which I spend most of my time
on and an appropriate assessment of the children is critical. If you
want a second opinion, look up a COVD fellow at www.covd.org that is in
your area. http://www.covd.org/membersearch.asp?cn=CA

I only think about the welfare of your children, I make no money from
advice here, in my practice, I only concern myself with the welfare of
my patient and what is best and make my recommendations. I only have a
script of +1.00 and I actually stopped reading in grade 1 due to the
same issue of eyestrain. I was 28 before I realised I had a problem and
that I hadn't read a book since then.

There is a lot of interpretation of what constitutes vision. We also
have a few non-professionals here who like to scare-monger that you
will damage your children's eyes. They post fictitious accounts and
have no basis to make these posts, but they like to think they are
saving your soul from the damnation of glasses. One absolute guarantee
I can make to you is that reading glasses will not do any harm to your
children in any way.

All the best.

Actually, I was in for my own check-up yesterday (time for reading
glasses) and asked to see my kids' results.

One has +1.25 in each eye, while the other has +2.5 in the right eye,
and +1.25 in the left.

I would ask the eye doctors who prescribe their rationale for

I tend to NOT prescribe for low amounts of hypermetropia in children
when they are completely asymptomatic and do not have any significant
findings -- glasses aren't free.

However, if they have subnormal VA, esophoria, difficulties in
school/learning that I can possibly attribute to refractive error,
then I will not hesitate to prescribe.

What is "low"?  I tend to follow the guidelines given in the American
Academy of Ophthalmology's Preferred Practice Patterns for Pediatric
Eye Examinations (which only go from age 0-3).

Does the situation change when you become adult? I have a low reading
for hyperopia, but the optician said I didn't need glasses, only if I
had a problem.

Why shouldn't the same apply to children?

My point exactly. As long as they have no trouble seeing and no
symptoms, glasses are useless. If I were hyperopic and glasses did
nothing, why_would_I_wear them?

Children with convergence excess and a high AC/A ratio many times
fatigue quicker or use excessive effort when reading/studying.  Many
times they don't realize this because they have no point of comparison
-- IOW, they don't realize what clear, comfortable, effortless vision
is.  When they fatigue quicker than their peers, they are at an
educational disadvantage.

>If I were hyperopic and glasses did nothing, why_would_I_wear them?

If they in fact, "do nothing" they shouldn't be prescribed.

A doctor should be able to give a valid reason or purpose for
prescribing glasses.  Everytime I prescribe glasses, I am able to do
so.

I am MUCH LESS apt to prescribe for asymptomatic low hypermetrope
adults.  In fact, I almost never prescribe for them.  I mean the
purpose of glasses are to solve or prevent problems.

Because children don't know what is best for them many times.

I saw what you wrote to Ace. Yes, Children don't have a valid point of

Sounds like me to be honest though. Im 29, and as I said in another
thread, I think Im about +.75 in each eye, and ok, I have a slight -.50
astigmatism, but even at these small values, the difference the glasses
make are unbelievable.

They really do bring everything into sharp focus and get rid of eye
strain and ease fatigue.

It's very subjective.

Some people find such a prescription to provide little improvement;
others find the changes "unbelievable".

The clearer one's focus, the less eye strain and the less fatigue the
easier one is able to process visual stimuli and learn.

IOW, you don't want your brain power dealing with optical defocus,
strain and fatigue when it could be processing important information.

I also have slight astigmatism in roughly the same range, but only lost
the ability to accomodate after about age 40.  Prior to that, my vision
was 20/17 in my best eye.

Young children can probably accomodate such variations more easily.

For small amounts, you are quite right. Your kids apparently have an
amount of hyperopia that is on the borderline between a small and a
moderat amount.  We probably wouldn't be having this discussion if they
were +.75 or +4.00.  By far most authorities wouldn't Rx for the former
and would for the latter for little kids. It's that pesky borderline
situation that warrant discussion and consideration.  The biggest
problem on s.m.v. is that we have a couple of guys who disagree with
mainstream modern eyecare and prescribing. I wouldn't have any problem
with that, except that neither of them has any formal education in the
subject, only some highly questionable self-education.  If they could
find a single o.d., m.d., or Ph.d. in the eye field come on this forum
and support their positions, now there would be a good discussion.

But they can't find even one to do so.
otisbrown@pa.net - 26 Aug 2006 21:43 GMT
Dear Pat,

You came to S.M.V looking for the second-opinion -- that was
already confirmed by two ophthamologists.

You can, if you wish, follow the OD majority opinion, and
place the twins in a +1.75 dipoters plus -- which they will
wear all the time.

The opthamologists who SUGGESTED that you kids
not wear the +1.75 diopters -- do not have time to
post on s.m.v.  The have  job to do, and their own
children and grandchildren to worry about.

On most medical subjects (if the natural eye's proven behavior
is even "medicine) you will find two opinions -- often profoundly
contradictory.

The point is to identify these opinions -- and make your choice
accordingly.

To read some more of this "second opinion" I would suggest reading:

www.chinamyopia.org

Steve Leung OD simply does not have time to come
on s.m.v.  He has his hands full helping his own children.
That is how it should be.

If you keep the "plus" off the twins, then their refractive STATE
will "move" slowly down, to 1.5, then 1.0, then +0.75 then
0.5 diopters.  This is a normal process -- and you can monitor
if you wish.

Under specific circumstances, when their refractive STATE is +0.5
diopters,
and in school, I do argue that at that point, the plus could be used --
for
prevention.

But these are the nature of scientific arguments.

For now, I would consider following the advice of the
two ophthamologists you consulted.

Best,

Otis

I believe the majority of ODs here have recommended NOT using glasses
without further evidence of problems.

Not that you care.

You have a spherical equivalent of only +.5 but for someone like you
with poor accomodation, your vision will be blurry at all distances and
you wont be able to read without reading glasses or plus. You might be
able to strain to accomodate in the distance enough to pump out a
couple 20/20 guesses but your eyes will quickly fatigue and your head
hurt from the strain.

I am not gonna label you as picky because its much worse to be
farsighted than nearsighted. Myopes like me see perfect from near,
whereas hyperopes see extremely blurry from near. Also myopes can go
without correction and almost never get headaches, in fact to the
courty(spell?) minus glasses *can* give headaches, especially if they
are just a bit too strong! The reason is accomodating places a strain
and being myopic relaxes all accomodation. When I get orthoK and reduce
my -4.5 myopia, I will go without glasses most of the time like my -1
bro never wears glasses except to drive.

Ok questions:

Can you see 20/20 without correction, if not, how close?
How blurry are things from near(16 inches) without your reading
glasses?
Why are you wearing glasses?

So you have to ask questions? Why did you give me your considered
opinion before asking?

Yes, I can read 20/20 without correction. In fact, better.

At sixteen inches, things are clear, but not necessarily sharp.
Fractionally, marginally things are a little, shall we say,
"anti-aliased" lightly around the edges.

Why am I wearing glasses?

Im not.

In May 2005, I went for my annual eye test, and was told that things are
fractionally worse than they were the year before at +.75 in one eye,
and that glasses weren't recommended but I could get them if I wanted.

I had a pair made up to see if they would help with eye strain.

They did. They also made things a lot sharper than I could possibly have
expected. But that could also be due to the astigmatism rather than the
hyperopia.

I put them on now, and things still remain sharp. But I don't wear them
all the time. I still suffer from eye strain, but things are manageable.

Ace - 27 Aug 2006 15:06 GMT
Then its the headaches that force you to wear glasses even though your
distance is 20/20 and your near vision is only a little blurred due to
hyperopia and astigmatism.
In your case, your wearing glasses not for good vision, but the big
difference in not having to strain to accomodate your hyperopia. I have
simulated +.75 and even though my vision was still clear, it was a
strain and my eyes and head begin to hurt! So I can see your reason for
part time glasses wear, especially for near. Being myopic, I dont have
the headache problem and I see perfect from near.

Who said anything about headaches?

I didn't.

Again, you're just making stuff up.

Unless you've read differently, not only do help with eye strain at
times of need, but THEY ALSO GIVE ME BETTER VISION AND MAKE EVERYTHING
SHARPER.

Of course, in case you've forgotten, again, I also have a slight
astigmatism. So the glasses also solve that little hurdle as well.

> I have

Eh? So beause that's how it is with you, that's how it must be with
everyone? Don't really care how it makes you feel, Im the patient.

Explain this +.75 simulation? Monkeying around with your lenses again or
something?

> So I can see your reason for
> part time glasses wear, especially for near.

Except you don't, because, as I've already said, although I've had them
made up, I don't wear them, despite the obvious benefits.

The reason why I don't wear them, is because I have acceptable vision,
that I personally feel that I don't need to wear them.

> Being myopic, I dont have

Let me explain again.

Yearly, I go to the optician for a checkup. Im a computer user. I get
told what my values are time after time. Sometimes its plano, sometimes
it's just a slight hyperopia and slight astigmatism (-.50).

Last time, I was checked to be +.75 hyperopia and -0.50 astigmatism.

My optician said that the values were higher, and I'll probably need to
think about getting glasses at some stage, but he said "you don't need
glasses now, unless you feel you have a problem".

I didn't feel that I had a problem.

But I did have a degree of eye strain that was getting me down at the time.

I went to the optician and had them make up a cheap pair of glasses for
me to see how things worked.

So I found that the glasses actually relieved my eye strain at the time.
But on top of that, the glasses actually made things clearer and sharper
to see. I didn't expect that.

It's been a year since I had the glasses made, and six months since I
was told that I had returned to plano. Given my thyroid condition that
seems to affect my vision each time I need an increase in my meds, and
the fact Im plano, I don't wear the glasses so much anymore. I just wear
them as required, such as if my eye strain gets me down or Im having
trouble reading things.

Yes, even now, the glasses would still work. I can look at the text Im
writing now without glasses, and it looks ok here at the moment, it's
fine. But the glasses will just make it a little sharper, as well as
helping with any eye strain.

Do they help? Yes.
Do they help even now? Yes.
Do I need to wear them? No.
Why did I get them? At the time I had a lot of eye strain.
Do I wear them now? As required.

Does that explain it all?

Honestly Ace, you have to learn to read and stop making assumptions,
such as "Oh, you have headaches" when I never said a word!

Ok, have you asked your doctor why your prescription isnt stable? Mine
has been stable for years save for the gradual improvement in the last
18 months, but thats due to addressing the pseudomyopia component.

So you are a latent hyperope and starting to become presbyopic and its
showing in the manifest refraction. Whats your cycloplegic refraction?
That could be the reason you had eyestrain, especially for close work
like computer.

latent hyperope, see above.

Thats normal. I also see clearer from near if I take my glasses off or
put on reading glasses over my full power glasses.

In what way is your thyroid condition affecting vision? Id get a
cycloplegic refraction and find out once for all how hyperopic you are.

Thats hyperopia for ya! Youll need readers, especially as you get

I guess I must have assumed wrong. Thanks for clearing it up. You are a
hyperope with more latent hyperope and at your age, your accomodation
decreasing.

Two schools of thoughts, first there were different testers, and then

Yes, I'd quite like to have a cycloplegic exam done. As for presbyopia,
that only comes after about the age of 40 (usually) doesn't it?

It's normal? Even for people who are plano? Mind you, I suppose part of
the issue with pluses, they work like a magnifying glass don't they?

Have a look for hyperthyroidism. That apparently with thyroid eye
disease can push the eyeball out. I wondered whether being hypo could
have the opposite effect. Certainly being hypo though could encourage
you to lose a certain amount of muscle tone or control, which apparently
is one of the reasons why people who are hypo, get excess acid - or
maybe they don't get excess acid, it just has an easier time of coming
up thereby creating heartburn. So it could be perfectly feasible that
you aren't in control of your eyes as much when you're hypo. Certainly I
think I've found a correlation between my vision and going back down in
the trough of hypo.

Never assume, Ace, it's a dangerous game.

Hope the doctors figure out this baffling case.

Just ask your optometrist for cyclopentolate, cyclogyl. Presbyopia
starts at birth but usually doesnt become an issue till your mid to
late 30s if you are plano. Because you are hyperopic and may have more
latently, you are feeling the effects earlier. Plus glasses sharpen
things for near. Taking off my minus glasses does the same for me so I
am mildly presbyopic or have reduced accomodation. Ive been told by an
optometrist that myopes dont have as good accomodation because their
eyes have adapted for near by becomming myopic and are used to seeing
from near without glasses.

> It's normal? Even for people who are plano? Mind you, I suppose part of

You are +.75 which means you have to constantly accomodate so things
come in focus behind your retina. This is not a large refractive error
and is why you still see 20/20 distance and only slightly blurry near.
Plus both magnify and sharpen, its the same when I put them over my
full power distance glasses, things get bigger and sharper! Of course I
just take my minus glasses off, tried putting plus just to see how it
works.

Ill have to read into this. If it happens to me, I will end up less
myopic.

More lies and misinformation.  Why don't you pull the plug---on your
useless life.

>Presbyopia

WRONG.  Presbyopia is defined, from the Latin route of the word as "old
sight".  It is a condition resulting from loss of accommodation due to
age-related changes in the eye. Of course YOU might say that you begin
dying the moment you are born.

>Taking off my minus glasses does the same for me so I
> am mildly presbyopic

WRONG. YOU are a child. You do not have presbyopia.

WRONG. ON the retina photoreceptors, NOT behind it.  

And how in hell did you make this up. Complete NONSENSE:

With respect, I wrote that.

I know TED can affect hyperthyroid sufferers.

I suffer from hypothyroidism and wondered if there might at all cause
things to happen the opposite way to TED, some interaction with the eyes
at least.

What gets me wondering, is that my eyes are usually the first thing to
go a bit blurry and tired. After a few months, I find my TSH is high and
I need more thyroxine. Once I've actually got my thyroxine level
adjusted, my eyes seem to miraculously return to plano. That could
explain the rollercoaster eye prescription for myself.

I hypothesised that there might be some issue with muscle control etc,
given that people who have hypothyroidism do have problems with stomach
acid, I've sometimes heard it suggested it's because when hypothyroid,
you can have problems with the lower oesophageal sphincter. If that's
the case maybe it could affect the muscles of the eye and explain
problems with focusing.

I have no idea if it's true, it's a promising idea, but Im not
suggesting people with eye problems have thyroid problems though...

> With respect, I wrote that.

I apologize for the confusion. I should have noticed that the flow of
thinking is more sensible than anything Ace might dream up.  I scanned
and stopped. Sorry.

From what I know of thyroid eye disease, the physiological changes from
Grave's disease (hyper) or Hashimoto's (hypo) thyroiditis occur as an
autoimmune pathology affecting the extraocular muscles.  In rare(r)
cases, the compression of tissues behind the eye can affect the optic
nerve and cause decreased vision. Control of thyroid hormones does not
appear to significantly effect the course of the disease.  AFAIK, there
is no clear rationale for that.  Also, the eye pathology can occur
without clear hormone imbalance and hormone imbalance can occur without
eye pathology.  The internal ciliary muscle is not affected. There is no
model for why visual acuity might fluctuate as a result of hyper/hypo T.

In Grave's, some patients do recover at least some normalcy in the
extraocular muscles following thyroidectomy and careful hormone control
and without surgery.

What YOU decribe seems more like that which occurs with faulty glucose
metabolism as in uncontrolled diabetes.  As diabetes is an autoimmune
disease as is Grave's and Hashimoto's, I think that is where you should
be looking.

That's pretty much all I know off right off without involved research.
Perhaps one of my colleagues might be able to add some additional
insight.

Right, OK, knew there had to be a reason for the "bulging" eyes type of
thing, and of course if you got some stuff going on behind the eye. The
whole TED is something Im not familiar with - having never had it, and
never researching it.

Im still going to think about the "muscle control" aspect when
hypothyroid, although the diabetes is an interesting one, given that I
am overweight and consume lots of sugar. But I have had my blood tested
with the pinprick thing - Is that a blood glucose test? Anyhow, either
way, that came back normal so we pretty much ruled that out, and given
my thyroid problems and regular blood tests every few months, nothing
else has shown up.

> That's pretty much all I know off right off without involved research.

Well, just so the question of my hypothesis isn't lost, what causes this
"rollercoaster"  effect of plano to +0.75 to plano to +0.75 where the
+0.75 seems in my experience to correlate with undercorrection of my
thyroxine levels. I'll leave that for the board.

Cheers

The "pinprick" blood sugar test only measures blood sugar at the instant
the test was done. It is NOT a test for diabetes. You should find out if
you had a GTT (glucose tolerance test--short term sugar reaction) or the
most appropriate test, the hemoglobin A1c test (long term sugar
reaction.)  Both of the fore-mentioned are done to diagnose diabetes.

Dear Ace,

It is true that some people LOVE glasses.

That is fine -- so give them the glasses they love.

We often do not get what we want -- we get
what we deserve.

Think about it.

That's correct Otis and some people SHOULD love glasses, you for instance.

Simon explained clip and clear why he OCCASIONALLY  wear glasses.

Fully agreed.

Free to Marcus Porcius Cato's "Ceterum censeo Carthaginem esse delendam"

In conclusion, I think that the "old plus lens junk recovered by Otis"
should be destroyed.

I've thought about it, and conclude you a selfish arrogant dangerous
cold hearted ignorant manipulative and evil.

To talk like this suggesting people who wear glasses get all that they
deserve.

He did.

Otis would kind of remind me of Herman Munster, oafish buffoon, except,
