I wear my glasses all of the time, both old and new prescription.

How much do you wear this prescription?  All/some of the time? That may be a
clue.

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?
