Hi
I've got a very unusual problem.
When I look at any lcd monitor, instead of a whole picture, I see a grid of
individual pixels. It happens from almost all distances, on all kinds of lcd
monitors.
It is a quite big problem for me, becouse I work as a programmer.
I haven't yet met a man, that has a similar difficulties with lcds.
I'm now writing on my laptop, which has a 14.1 screen and a very small pixel
size, but I can still see patterns of pixels instead of a flat picture.
Is it possible, that my vision is too sharp ? How is it possible, that there
are no other people with such a clear and detailed eyes ?
Please write, what do you think about it.
Thanks in advance

thats an odd complaint. I have never heard that one before. i will
talk to some colleagues and respond if i get some useful information.
sorry.

Maybe you just learned to focus on the pixels instead of the picture as
a whole? I can do the same if I tried but ive learned to look at the
whole picture. I think its more of a learning process to condition the
brain to see the big picture. What is your snellen visual accuracy?
Probably 20/15 or therebouts. You should be thankful your vision is so
good!

"Too sharp" is a term we seldom hear.
It sounds like a good reason to trade with someone who has a CRT monitor.

Actually, I was wondering if extra sharp vision might be a factor in
convergence issues. The increased acuity would increase the workload
on the system to keep the eyes perfectly aligned. With less sharp
vision, there'd be more room for slop.

When we're trying to improve alignment, better acuity is usually helpful;
never heard of it hindering fusion.

I am not a health professional.
As I look at my LCD display, I can see raggedness and other artifacts
association with pixels if I choose to do so. And my eyes are not in great
shape. Usually, I just ignore them.
It is like people observing normal floaters when looking at the sky. It is
easy to see them once you know what to look for, but why have them upset
your life.
On the other hand, it is well known that some people make better radar or
sonar operators when looking at oscilloscopic displays. They just seem to
have their nerves and brain wired in unusual ways. If that applies to you,
you may have something to offer those who investigate that kind of
phenomenon.
I would start out with optics, like looking through the wrong end of a
telescope, just to see what your ultimate resolution is. The task would be
to distinguish gray from a black and white checkerboard from a uniform gray.

Back in February 2000, I wrote about some of the first patients treated
by Dr. Prof. Theo Seiler of Germany with the Allegretto laser, using
the Dresden Wavefront Analyzer. Of the first twelve patients treated,
three achieved 20/15, two were 20/10, and one was 20/8. Dr. Seiler said
that that patient was unhappy with her new vision, as she could no
longer watch TV. It seems that rather than seeing a clear picture on
the screen, she could see the raster lines! Others who got 20/8 vision
did not complain about that problem.

And so here we are, more than six years later and "custom LASIK",
wavefront, CustomCornea or whatever you want to call it has turned out
to be nothing more than another marketing pitch. Sure, it allows for a
little better outcomes for some people and allows the procedure to be
acceptable risk-wise for others. But overall, the actual number of
people achieving uncompromised acuity equal to that offered by contacts
or spectacles has not changed.
So much for "hyper-acuity." Hasn't happened. Myth.
The number of poor outcomes has likewise not significantly changed
(controlling for appropriate patient selection, surgical skill and
choice of equipment and software.)
But thanks for the info.

I also read about so called super vision and it has yet to materalize.
Todays technology has too many shortcommings. I did read that by the
year 2010 lasik is supposed to give most people 20/12 or 20/10 vision
but thats overly ambitious. I think anything 20/20 should be considered
excellent, so as long as your quality of vision is fine, especially at
night. Wavefront lasik DOES induces aberrations, just a "reduced"
amount compared to tradational lasik. RGP contacts mask some of your
aberrations so if the best possible vision is what you seek, wear RGPs.
Lasik improves uncorrected vision but will NOT give you supervision or
sometimes even 20/20 vision but it can improve how well u see without
glasses.

I tended to notice the scan lines after lasik. After a couple of hours my
vision just seemed to ignore them.
Thats why there is HDTV. Even with HD, a person with good vision can still
see scan lines. I'm really looking fwd to when everything is broadcast in
1080p!!

I have this problem too... the only logical solution I have is to sit
as far as you can from the screen, I sit about 1m far from the screen.
Best regards,
Eli.

I notice this too, but only on some LCD screens.
I've tried adjusting the refresh rate in display properties but it
didn't help.
So I don't know the answer to your problem but you're not the only one.
I don't let it worry me too much.

What exactly do you see mean by "pixels"? The picture on an LCD monitor consists
of _dots_ of three different colors (red, green and blue) placed alongside each
other in certain pattern. "Pixels" is just a convention by which one can group
those dots together, which is not represented on the LCD screen in any physical
way. In other words, it is not possible to see "a grid of pixels". What is
possible is to see a grid of _dots_.
If that's what you see (dots of _three_ _different_ _colors_) then your vision
indeed seems to be too sharp. If you see something else, then it must be some
other effect, not necessarily caused by "excessive" sharpness of your vision.
For example, some types of LCD monitors display the picture by alternatively
lighting up two different groups of pixels. Each group is organized in a
chessboard pattern. (Imagine a chessboard: first only the white squares are lit
up, then they switch off and black squares are lit up, then white again, and so
on). When one's eyes are fixed at single point on the screen this switching
process is not visible, since it happens pretty fast. However, when one's eyes
are moving across the screen, the chessboard pattern might become rather
apparent. This is sometimes reported as "seeing a grid of pixels on LCD screen".

Have you considered exchanging your LCD monitor for a CRT one? Bring
us your LCD model and we'll give you my wife's CRT monitor. She feels she
would prefer LCD.

Dumb idea, as usual from that poster. I'd have to charge postage
or freight and that'd cost ya.
I should get together a downloadable book about making one's
own eyewash, and sundry elixirs and potions. The first chapter,
about uses of tap water, is almost complete.

The best visual acuity possible with eyes the size of ours is apparently
20/8. Ordinarily a larger-aperture pupil would provide better resolution,
but aberrations cancel this advantage out if the aperture is too large.

I suspect that what you are seeing is jagged fonts on your LCD caused by
not having font smoothing, ClearType, enabled. Try going to Display
Properties (on WinXP right click on the desktop and select properties);
then to the Appearance Tab and then to Effects. And enable font smoothing,
setting the smoothing to ClearType. You are likely to find a tremendous
difference on an LCD screen if clear type was not previously enabled.
