Problems with pinhole glasses

Hi all,

I've been experimenting with pinhole glasses for a while, but they
don't seem to work for me. (I can still return the glasses.) I'd like
to know if other users have had similar problems and if they did or did
not find a solution.

I'm moderately myopic with some astigmatism. When viewing through the
glasses, I see the grid between the holes fairly clearly, even though I
do my best to look through the holes.

The biggest problem is that when objects move in my field of vision,
they "double" where they move from one hole to another. That is, the
objects double or even triple if they appear in an area of my field of
vision where two or more holes intersect. This is very uncomfortable.

Also, I don't see as clearly as with my prescription glasses. And I see
more clearly if I look through the edge of a hole rather than through
the center of it.

The manufacturer's representative told me that some people's eyes never
get used to the grid, but almost all those whom I've asked to try them
have found the grid distracting, with the same doubling/tripling effect
I've experienced. If you are using pinhole glasses, do you actually see
clearly and without problems with them?

I'd be very grateful for your experiences and advice.

 

Advice- pinhole glasses for any type of "vision improvement" is
just a sham. Pinholes just don't work.
Get your money back if you can and wear
your prescription glasses.

"Pinhole glasses vision improvement" is a scam. Sales have been banned
in the USA.

LB, O.D.

 

I bought some for a quarter at a yard sale. They indeed cleared up my
vision, but at a price -- narrow angle of view and REALLY dark. They're
a gimmick and worth just about what I paid for them.

 

I experience the same thru pinhole glasses. Also they only get me to
20/150. Pinholes are a good idea for children just starting to become
myopic and who wish to avoid stair-case myopia that a minus lens
causes. Those children use pinhole to clearly see the chalkboard and
plus glasses to read. This helps slow or stop their myopia progression.
As for vision improvement, just take your minus glasses off for
reading, use reduced minus for the computer and around the house

 

Mike Tyner:

I am too myopic to get good vision thru pinholes.(20/600 UCVA, 20/150
pinholes, 20/50 tiny hole in a piece of paper, 20/25 with glasses) You
will always see much better with full power prescription glasses than
thru pinholes. Now if I place pinholes over glasses, I see even better!

If you are unable to purchase pinholes, you can simply make your own.
Or you can just move closer to the board or copy someone elses notes. I
wish I had gone without minus glasses as long as possible and if I had
to use them, only for emergencies and driving.

Proof has been shown, but you M.O optometrists believe in what you want
to. I can only hope oneday myopia prevention is taken seriously or
almost everyone is going to become myopic. Already more than 50% of
people in some countries are myopic!

 

"Already more than 50% of
people in some countries are myopic! "

hmm, that is an interesting figure. what countries are we talking
about? are they located here on good old earth, or far, far away in a
galaxy we haven't visited yet?

anyway, mean jokes aside, i would really like to know which countries
you are talking about. seriously, what countries, pray tell???

In the U.S., the prevalence of myopia is about 25 percent of the
population, but in Asian countries such as China or Japan it may exceed
70 percent, and it approximates 90 percent in selected populations,
such as Chinese university students.


Short-sightedness is common in many areas, but it is enormous in such
countries as Singapore. By 18 years of age, 80 per cent of local people
have short-sightedness, 30 years ago there were only 25% of such
people. The police has lack of people with normal eye-sight, in
addition, too many people have too high short-sightedness, they can
become blind because of it.


According to another research, 80 percent of 14-18 year-old male
students in Israel high school majoring in religion, suffer from
myopia. Meanwhile, in the state schools, only 30 percent of young
Israelis have myopia. So, the lifestyle should be blamed for this
disease spreading.

As lifestyle changes, myopia is growing. Currently, half of 12-year-old
Swedish schoolchildren suffer from short-sightedness. When they turn
18, there may be 70% short-sighted among them, NTR.ru reports.

 

I found a website saying the benefits of pinhole glasses are huge!

Ace, that's because they are trying to sell them. Wise up a bit.

Also if you are going to copy and paste from websites as you have done
in your other posts, then you really ought to acknowledge the
source. Have you ever heard of plagiarism?

Dear Feathered One,

MYOPIA PREVALENCE IS ALWAYS HIGHER THAN 90 PERCENT
FOR TAIWAN MEDICAL STUDENTS


Re: Changes in ocular refraction and its components
among medical students - a 5-year longitudinal study", Optom.
Vis. Sci., 73:495-498, 1996) found that in a study of 345
National Taiwan University medical students, the myopia
prevalence increased from 92.8% to 95.8%! over the five year
period.

******************


1) In Singapore, the vision of 421,116 males between the ages of
15 and 25 was examined. In 1974-84, 26.3% were myopic; in
1987-91, 43.3% were myopic. Both the prevalence and severity
of myopia were higher as the level of education increased.
The prevalence rate was 15.4% in males with no formal
education and increased steadily through the education levels
to reach 65.1% among the university graduates in 1987-91. The
authors state that their findings confirm indications from
other sources that the association between the prevalence and
severity of myopia and education attainment is real (M.T.
Tay, K.G. Au Eong, C.Y. Ng and M.K. Lim, "Myopia and
Educational Attainment in 421,116 Young Singaporean Males,"
Ann Acad Med Singapore, 1992, Nov;21(6):785-91).

2) Regarding the prevalence of myopia in Asian countries, Lam and
Goh (Lam, C.S. and Goh, W.S., "The incidence of refractive
errors among schoolchildren in Hong Kong in relationship with
the optical components", Clin. Exp. Optom., 74:97-103, 1991)
found that in 383 school children from ages 6 to 17 years, the
prevalence of myopia increased from 30% at ages 6-7 years, to
70% at ages 16-17 years.

3) Lam and Yap (Lam, C.S. and Yap, M. "Ocular dimensions and
refraction in Chinese Orientals", Proc. Int. Soc. Eye Res.,
6:121, 1990) found that in a group of optometry students at
The Hong Kong Polytechnic University, the prevalence of myopia
was 75% in females and 69% in males.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

CRITICAL TRUTH:

4) Goh and Lam (Goh, W.S. and Lam, C.S., "Changes in refractive
trends and optical components of Hong Kong Chinese aged 19-39
years," Ophthal. Physiol. Opt., 14:378-382, 1994) found that
in 2000 first-year students at the University of Hong Kong,
the prevalence of myopia was 87.5%.

that is a total copy and paste from the article you referenced in
another thread, but it is posted as if it is your own words,
weird...........

also, since the article you found is a short summary of data supposedly
collected from around the world, condensed and presented for review,
but, pray tell, where did these figures come from, what clinical study,
sources and links to verify the informations contained therein so we
can see how this data was compiled......

Again, your shortsightedness is showing, no, it is glaring.

The only thing good about your copy and paste is the spelling is
usually much better than your normal prose...........................

If he quoted there wouldn't be any original material and
people wouldn't think he is as smart as they do now...
well, maybe not. lol

update, another thread provided the data summarized with his copy and

What is the "grid between the holes"? Is that what you mean to say?

By it, I simply mean the opaque black material (that appears as a
"grid" or "honeycomb") between the holes. The sales representative said
one should not be visually aware of the opaque part when seeing through
the holes, but practically everyone who has put the glasses on has seen
it.

The image doubling or tripling has also been experienced by all who
have put the glasses on. The reson for this is probably simple:

The holes in the pinhole glasses are, well, separate from each other.
When an object seen through the holes crosses from one hole in the
field of view to another, it "jumps" or "doubles" (obviously so, as the
holes are some distance from one another).

I guess the idea is that one's eyes should stop seeing the opaque
material between the holes, ie that it disappears and one starts to see
in the same way as when using normal prescription glasses. It just
doesn't seem to happen.

Excellent. I forwarded the site address to the US FTC as a complaint
meriting investigation as fraud.

Too bad I can't have them investigate YOU as a fraud.

LB, OD.

 

They have broke no laws, pinhole glasses dont require a prescription.
They are legal and anyone can buy them.
