Sure. But advertising that they improve vision or prevent myopia is a sure
way to get the FTC knocking on your door.

The smarter way is to find nitwits who will advertise for them.

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

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.

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.

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

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...........................

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%.

Enjoy,

Otis

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?
