Dr. Judy,

Yes, my orginal post was WITH bifocals. But in my other posts, I also
described my vision WITHOUT correction, which is my normal everyday
life (I don't wear correction much, except at night for driving and at
work when I have to go on the manufacturing floor).

The truth is, when my DO checked my eyes and gave me the -.75R / -.50
L prescription, he didn't actually test my closeup with a +1.25 add.
Since I rarely wear by bifocals, I never paid attention to the fact
that my left eye doesn't see fine print as well as my right eye does...
*corrected*. This is why I was wondering if presbyopia can be worse in
one eye and not the other.

As for the *corrected* distance vision, my left eye sees slightly
sharper than my right eye. I was told I could go 1/4 diopter stronger
in the right eye, but it would be a bit too strong and my right eye
would see sharper than my left eye (that's when he told me I'm "in
between quarter diopters" in my right eye).

So if I'm understanding you all, I should *not* have such a variation
in corrected closeup vision (bifocal add of +1.25) if my distance
vision was properly corrected (which is seems to be)??

I'm getting confused now. In your original post you were (I thought)
describing your vision with bifocals on, this post seems to be about
vision with glasses off. It is normal for the more myopic eye to be
blurrier at far and clearer at near with glasses off.

Never worry about vision with glasses off. If your corrected (with
bifocals on) vision at near is blurred with the left eye, your last
check up was just a few months ago and the left blur is new since that
check up then you should return to your optometrist to check out
whether the blur is refractive or due to an eye health issue.

It would be consistent with the average at age 42.

But you didn't mention cylinder.

For a more accurate refraction?

I suppose that's possible, especially with presbyopia setting in? I
remember when I had my eyes tested last Dec, I told the DO that, when
corrected for distance (without cylinder and axis correction), my left
eye was a bit sharper than my right eye. And that my *midrange* was
sharper in the right eye than the left eye. He said that my right eye
was probably between quarter diopters, where a -1.00 was a bit too
strong, so he left it at -.75.

Maybe I should see an opthamologist?

Yes, I'm positive about the -.50 and -.75. I'm looking at my
prescription. The astigmatism is supposedly in my left eye only, which
is -.50 cyl and 170 axis. I think the doc is wrong about this because
he is the first eye DO that has ever prescribed a correction for
astigmatism. I have a pair of glasses with the astigmatic correction,
and 2 pairs without. I notice no difference whatsoever in the left
lenses in any of the glasses.

I shudder to admit it but I agree with Aceman. When the prescriptions are
truly within 0.25, the differences between right and left vision are pretty
subtle. You aren't describing a "subtle" difference here:

So I'd guess your prescription has changed over the past few months, with
the left eye growing _less_ nearsighted, closer to plano (zero).

Thats really odd youd find such a big difference between -.5 and -.75
are you sure its correct? How much astigmatism do you have? Give me an
idea of the difference, what is your uncorrected distance vision in
each eye(based on snellen chart)

Oh, I wanted to add... when I wear just my distance lenses (night
driving, mainly), my closeup vision in my left eye is quite awful, and
my right eye sees poorly (like my uncorrected left eye).

I also occasionally wear monovision AV2 contacts -- +.50 left and -.75
right. They work pretty well for me, kind of like reverse of how my
eyes work without correction. I can see a computer screen really well
with the monovision contacts, however, closeup vision in my left eye is
better than no lens, but not terrific. I was going to request a +.75
lens from my eye doctor, but I'm afraid it might mess up my midrange
and computer vision.

I saw some posts about "accommodative spasm" and "accommodative
excess". A couple of years ago, someone bought me a "Magic Eye" book
of those images that become "3D" when you stare at them long enough.
Every time I'd do that, I couldn't see far away for several hours. My
eyes felt like they were "locked". I thought I had damaged my eyes
somehow! Consequently, I never tried those "Magic Eye" pictures ever
again! Could this have something to do with my unusual vision?

Yes, I am more myopic in the right eye, and most of the time I don't
wear my bifocals. However, when I don't wear them, all my closeup
vision is with my right eye... as my left eye can't see clearly at all.

Hi Dr. Judy,

My last check up was this past Dec. My left eye sees really well far
away, and my right eye is poor. Closeup is the exact opposite. I can
still see well closeup with my right eye, but the left is awful.
Printed text look small and unreadable. I still get by without wearing
glasses (which is most of the time). My eyes do a kind of "natural
monovision", I guess.
