Pinhole glasses good for computer work?

Hi all.

I'm shortsighted programmer, wearing glasses with -1.0ph/0.5cyl dioptry on
each eye, and after only 2 hours of working in from of my LCD, my eyes hurt
quite a bit. In fact, they hurt all the time, because they don't have time
to rest properly, even after night sleep.

Now, I heard about this pinhole glasses. I've read a bit about how they
work, and I know they will not improve my eyesight, but I'm curious whether
they will put away strain on my eyes when I work in front of computer?

I know they reduce peripheral vision, but I don't need peripheral vision
when I work with computer.
I know they reduce brightness, but I have enough of brightness (probably too
much) from my LCD, so it doesn't bother me also.

So, could it do me good?
And most importantly, can they harm my eyes somehow?

Regards,
Vjeran

They won't do any harm to your eyes, so by all means give them a go for
a few hours. You'll probably find them so frustrating that you'll give
up on them before long.

Do you currently wear your distance vision specs while using the
computer? If so, try taking them off. Also, try eye drops (artificial
tears). I assume you've had a thorough eye test recently to exclude any
other causes of sore eyes.

why would you even need glasses for the computer? If your a -1 and sit
1 meter(or closer) you will see better without glasses than with! I am
about a -5 but wear -3.25 glasses for the computer and my eyes have
never felt more relaxed! You dont even need to wear your glasses much
except for driving or watching movies

Why don't you try. They come with different pinhole sizes
and patterns. Usually they are the ultima ratio for people
with 20 diopters :-)

For computer work you need glasses with varying focus.
They are expensive and not every optician can make them.
In fact, many sell glasses from cheap manufacturers
and do not know how to handle varying focus glasses at all.
You must specifiy "computer work", and explain what it means
optically, otherwise they will set the upper part of the glasses to
infinity focus, be careful, they are salesmen.
Sometimes you need to look around the office, through the upper
portion of the glass, that is 5 to 7 m distance,
and the shortest distance at the bottom
of the glasses will be keyboard, respectively reading a book,
that is about 40 cm. Set the center to 70 cm or 1 m distance.

I have such glasses and about the same diopters as you.
Can work for hours without problems,
although not the whole day, need to have a walk in the green
sometimes.

Doctor told me that even if I don't have any problems seeing things at close
(because I am shortsighted), I should wear glasses constantly, because
adaptation of eye when taking glasses off is not healthy...

Pinhole glasses to improve vision is simply a scam- they do not work.
Sometimes dedicated computer glasses with ar (anti-reflective)
coating,
a gradient tint can be of help. Also, sometimes using artificial tears
and
looking away from the monitor every 15 minutes or so can reduce eye
strain. But the pinholes are simply a waste of money.

sorry thats not true. In fact using glasses to see from near when you
can see fine without will make vision worse, see pseudomyopia which
eventurally will increase enlongation of the eye.
You have the gift of seeing well from near without glasses, use it!

This statement is not true, at least not completely.
What would "work" mean in such a context.
You probably wanted to say,
pinholes are not adequate replacements for optical glasses.

Of course they work, pinholes are physically functioning optical
elements, and can replace a camera lens
Enter "pinhole" in Ebay:

And when you combine many pinholes you get that:
http://cgi.ebay.at/Pinhole-Glasses-R...QQcmdZViewItem


The effect is surprising,
it is worth trying from a physics standpoint,
and may be useful for certain eye illnesses
although I prefer normal glasses :-)

Pinhole apertures are commonly used in target pistol shooting to improve
the depth of field by simultaneously reducing the blur of the front and
rear sights as well as the target. There is no conventional transparent
lens which can accomplish that. For certain types of eye defects a
pinhole lens can provide better visual resolution than a full aperture
glass lens. The downside of pinhole lenses is Limited field and reduced
image brightness.

"glasses" with multiple pinholes were used in some parts of the world
long before glass lenses came into use. If the angular spacing of the
holes is approximately equal to the angular field of view of one
pinhole and in a hexagonal pattern. They give greatly improved
resolution, particularly for us old folks who have limited focus
accommodation. The "flys eye" effect takes some getting used to.

They work, and they work really well.

My son has a huge cast on his arm. It works really well also. I don't
have such a cast, or want one. I'm sure my HMO would refuse to put one
on.

My wife hurt her foot some time back. She used crutches for a little
time. I don't use crutches. I don't want crutches.
