.  I don't have a lot of history with eyeglasses. I am in my
40s and have only needed them for about 7-8 years now, and even then
I
really only like to wear them at work in front of the computer and
sometimes going to the movies or in front of the TV.  I don't need
them for driving or for reading.  Basically one eye is quite blurry
but the other one is fine.

My current pair was scratchy so I went to the local optician to get
an
updated prescription and new glasses.   The saleswoman asked me what
I
use them for and I explained exactly what I stated above.  I do the
eye exam with the optician and a week later pick up my glasses.  I
put
them on at home in front of the TV and everything is blurry.  I call
up the sales woman and she tells me "you said you didn't need glasses
for distance".   Long story short she said to bring them back and
they'll replace them, but I am still confused.

The past two times I got glasses (at a different place), they
provided
me with glasses that essentially restored my vision to 20/20.  I can
use them at work and when I get up from my desk I can leave them on
and still see everything fine.  With these glasses, everything is
blurry unless it is up close.  Is there a different prescription if
you say you only want glasses for up-close? I didn't know I had to
specify, as I never did before.  She didn't do a good job of
explaining this to me, so I am still confused.
