Well I'm really only guessing now... maybe your previous specs did have
a small amount of prism which wasn't replicated in your new pair but
should have been? If you are finding that you are not reading as
smoothly, or losing your place when reading, with the new pair, then the
prism may be a factor. As I say, just guessing now.

I'd book in for another test with your optometrist. Remaking the lens
without the cylinder (the -0.50 component of your Rx) and in a standard
optical plastic (i.e. CR39 not polycarbonate) would be a simple thing to
try.

Thanks for everyone's suggestions on what my problem might be.

Yes, Dom, the astigmatism and problem I'm having is in my right eye,
and if I close my left, the problem seems to go away.  I'm almost
wondering if I'm having almost a prism effect, and getting two images
that are close, but not aligned perfectly.  It almost feels as if my
right eye is always accomodating for far vision, no matter where I'm
looking.

My new lenses are polycarbonate right now, although I first had them as
plastic, and they tried changing them to polycarbonate to see if it
helped.  I liked the plastic a little better, but there wasn't much
difference to me.

Colors seem to be the same in both eyes, and print looks the same with
both eyes individually - it's just when I'm looking at them with both
eyes that I really notice it.

Oddly, I find that if I'm in a car, or behind another glass of some
sort, the feeling goes away.  Could I be having a problem adjusting to
a larger amount of light coming through my lens?  My old lenses were a
little scratched up before I replaced them.

2 months is plenty of time to get used to a 0.50cyl change.

Just to confirm: you say the *right* eye never seems to be in focus with
your new glasses, but if you close your *left* eye the problem
disappears? In other words closing your left eye puts your right eye
back in focus?

Are the new glasses made of polycarbonate material?

Do colours appear washed out with your right eye? Does print look black
or more grey with the right eye (compared with the left eye)?

Assuming your lenses aren't made of polycarbonate: you could have a
problem with your retina, or you could even have dry eye. Or the
optometrist could have just made a mistake with your eye test.

Hello there - I'm having problems with a new lens I prescribed, and was
wondering in anyone had any input.  I noticed I was having a blurring
effect out of my right eye, so I went for a check-up and the
optometrist ended up with a prescription that was almost the same as my
previous:

Previous: -2.25 in both eyes
New: -2.25 in the left, -2.00, -0.50 180 in the right

As soon as I put these glasses on, I felt odd.  There was a strong
pulling sensation in right eye, and I could never really seem to focus
it.  After a week I went back, and the optometrist said that people
often take awhile to get used to an astigmatism correction, and I
should wait longer and eventually my eye would feel normal.  However,
it's now been almost 2 months, and while I no longer feel the pulling,
my right even never seems to really be in focus, and I find it hard to
read anything (at any distance).  It's almost like there's no contrast
between foreground and background, so words just smear.  However, if I
close my left eye, the problem almost totally disappears.  I've had the
lens placement checked and rechecked, as well as the lenses, and
everytime everything checks out fine - the lenses are the correct
prescription, and they are centered right over my pupils.

Is it usual to take THIS long to get used to a new lens?
