Perhaps I didn't elaborate enough.  Let me try this again.  Yes, I
realize that it's an unusual  problem.  I've had it for 10 years, and
it's taken me that long to figure out that my vision changes too much
as the level of light changes.

With these glasses:
R: +1.75 +1.25 x 162 deg
L: +1.00 + 1.50 x 177 deg

*Distant* objects are in focus at low levels of light, i.e., driving
outdoors at night.  But as the level of light increases these glasses
become increasingly too strong to see distant objects.

But with these glasses:
R: +.75 +.79 x 179 deg
L: +.50 +1.00 x 007 deg

*Distant* objects are in focus outdoors during the daytime.  But as
the light level decreases these glasses become increasingly too weak
for me to see distant objects.

In both cases I can still focus on nearby objects by looking through
the middle or lower segments *because* I can position my head at the
proper distance from those objects without having to move my body
closer to those nearby objects.

Obviously this is impossible to do with the distant objects.

Here's the pattern with the stronger glasses at higher levels of light
(like outdoors in the daytime):

The maximum distance that  I can still focus properly on objects
through the upper (distance) segment is 5'.  This should be farther
away, like infinity.

The maximum distance that I can still focus properly on objects
through the middle segment is 16".  This should be farther away.

The maximum distance that I can still focus properly on objects
through the bottom (reading) segment is 8".  This should be farther
away.

But at lower light conditions, I can focus on infinity, and can focus
on nearer objects through the appropriate middle or lower segments, at
the proper distance.

So the darker the environment becomes, the more in focus the image
becomes through all 3 segments, and it's the best at night.

With the weaker glasses everything is in focus at too far of a
distance through all 3 segments.  I can move my head farther away from
the nearby objects and still bring them into focus, but the distant
objects will still be out of focus.

I don't think this violates the laws of physics.  In a moderately
farsighted person without corrective lenses, when  the pupil dilates,
the focal length changes, so the image is focused past the retina.
But  the brain sees the slightly out of focus image and sends a
message to the ciliary muscles to change the shape of the lens, which
causes the image to become properly refocused because the this causes
the focusing point to be moved farther forward to the retina.

In my case, I think that the pupils are becoming the proper size for
the lumens of light, but that the focusing mechanism is just too weak.

Because the focusing distance of the glasses is fixed and the pupil
size has been set to a fixed position for that level of light  by the
brain, the image will only become focused directly on the retina at
"x" distance.  That " x"  distance is now determined only by the size
of the pupil because the focusing mechanism isn't strong enough.

So it's like a camera with a faulty, weak, focusing mechanism.  You
can still change the size of the aperture, but the object won't be in
focus unless you're at the proper distance.

I'm trying to determine a way to use the stronger glasses outside
during the day by using some sort of tinted flip-up shades to reduce
the light level.  I'm thinking that because I can see very well out of
them at night when the pupil is larger, I might be able to make the
pupil larger during the day.

I would really appreciate it if someone could make some suggestions.
It's like I need a dozen pairs of glasses to cover the different
levels of light.

Sorry for the long post.  But I just didn't think I was getting the
point across.
