Is there eyeglass substitutes for Windows7?

Software would not work. There is a simple solution. Have
appropriate lenses implanted in your eye balls. I had it done. I am
71 and rarely have to wear eye glasses any more. It is called
cataract surgery.

Now and then someone out there has a bright idea that a person
might not have heard of.

For example, a couple of bright guys figured out a way to build a
camera that "captures the light field."
http://news.bbc.co.uk/2/hi/programmes/click_online/9568340.stm
What this allows the user to do is focus the image a week after
they have taken the picture or to focus on different parts of the
image, all after the picture has been taken. And focus seems to
be what the original poster might be looking for. The camera is
supposed to be available for sale as soon as they get
manufacturing going, and might be now.

And there are things like Fourier transforms that relate the pixels
on opposite sides of a lens. A conventional monitor today might
not have the resolution needed.

But they are claiming holographic resolution monitors will be
available soon.
http://news.bbc.co.uk/2/hi/programmes/click_online/9393762.stm

Suppose you could reproduce "the light field" or a hologram on
demand. Could that do exactly what the original poster was
asking for? Perhaps we need some math describing the optics to
to be able to answer this question.

Now a question for all you folks buying "reading glasses" (glasses
for the far sighted) for a few dollars a pair. Has anyone found a
source for reading glasses for the near sighted for a few dollars a
pair? All I have found in the stores are positive lenses (for the
far sighted) and have been searching for an identical display for
the near sighted. I sent emails to a couple of the companies that
have displays in the stores asking, but didn't get a reply.

Thanks for any tips.

Prescription only......

My optician actually tested both reading and computer monitor distances
with mine and they're fine, even on a wide-screen laptop....

I agree that they can be fine for both, *except* for one important
factor--the angle of view for the different parts of the lenses. For
me to use mine for the computer monitor, I have to tilt my head up to
look through the lower part of the lenses. That's so uncomfortable for
me that I never do it. With my eyes, at the monitor distance, no
glasses work fine.

For Internet cruising I use ctrl+

You might want to try Ctrl plus scrolling the mouse wheel instead.
Also note that that's a Windows standard and it works in many (but not
all) applications, not just your browser.

That's a problem for me even with the single-strength computer glasses
I use, because I'm a creature of habit. I.e., the fault, dear Brutus,
lies not in the optometrist, but in myself.

Because I generally use bifocals, I am in the habit of tilting my head
backwards for close viewing (it seems that the monitor qualifies), and
I can't seem to overcome the habit. It wouldn't be so bad if my neck
worked better :)

Great idea. I'm on it...

The ambiguity was unintentional, but I like it, so it stays :)
You and your language are taking it easy?
^^^^^^^^^^^^^^^
No, no, no. Lie on it. Do not run into it.

OK, I looked online for the PDF manual and I can't find it. Are you
sure about what you say?

Good first name, I say.

Oh, absolutely. Of course, fools who are totally wrong often are
sure, too, so that proves nothing.

Quite, quite. Common enough that there is no problem about how
to say it, but uncommon enough that there is usually only one in an
area, occasionally two.

Then both of you can fit in the shallow end of the Gene pool.

Watch your step. The Gene pool starts at 10' deep.
