Re: Incorrect Prism - Any Legal Action?

I have recently found out that my main pair of glasses has something
like a 2.5 diopter prism (I'm not sure of the correct terminology) in
one of the eyes, offsetting the lens centers. My Rx did not call for
this prism, and I have had problems with the glasses since first
getting them - although I thought it was due to a bad fit after about
a week or two. What eventually happened was that they started to
naturally get pushed into "misalignment" by my constant adjusting to
make them wearable, but I still noticed weird double vision when
taking them off and putting them on. However, I have been so busy away
at school I haven't had a chance to ask anyone about it until now -
thought the headaches were stress

I was told that there are certain legal standards that a lens maker
has to follow, and that my values were out of "tolerance" - almost 3mm
when my acceptable level is +/- 1mm. Other than asking the original
vision center to replace the lenses, am I entitled to or should I take
any legal action? Its kind of ironic that I did get into a car
accident two days before learning about the lenses being
incorrect...but I was not at fault.

Any advice would be great. Thanks.

Matt, reading your story I suppose it is a a mismatch in height of the
optical centers.
Also reading your story I suppose your prescription is about 8 (eight)
diopters.
It could be possible your frame is not quite 'horizontal' placed on your
face.
Thats to say on the right side some what lower than it is on your left
side ore vice versa.
When this happens you induce a prism in in height.
Looking at a horizontal line with one eye at a time you might see a
'jump' when you alternated use your right and left eye.
You can try to 'correct 'this by trying to push up or lower down just
one side of the frame when wearing it.
A difference off 3mm is easily reached.
Maybe and again maybe just a re-adjustment of your frame already fix
this problem.

BTW, 1 prisma in height difference is more or less acceptable for the
brains.
But better avoid it.

Hope this helps,

I actually have been wearing one side higher than the other, as it was
a natural way to reduce my discomfort - I wasn't even aware that I was
doing it until I thought to get them adjusted. My prescription is ~5
in each eye. I am wearing my uglier backup pair now, and have gotten
used to how "normal" feels. Its much more comfortable, especially in
the periphery and transitioning between looking through the lenses and
looking up or down without the lens.

Thanks everyone for your clarifications.
