I have a pair of glasses from '96 that I need to know what they are
made out of. The problem is that the store closed several years ago, which
and I can't return there to ask. After going though a couple of pairs of
glasses in '96 that were made out of polycarbonate that where just plain
awful, I returned to Cohen's Fashion Optical in Syracuse, NY where they
explained the problems with polycarbonate. They made a pair of glasses out
of what they referred to as high - R plastic that are great except that
they are now scratched all to hell and my arms are a little short.
When I read without glasses I notice the astigmatism and it's hard to
fill in a crossword puzzle when your face is closer to the paper than the
length of a pencil. My current prescription is
sph cyl axis add
OD -4.75 -3.00 168 +2.00
OS -5.50 -2.50 175 +2.00
This is close to my old prescription except no add.
The place I went to this time said that my old glasses are
polycarbonate
so they made a pair of progressives from polycarbonate. They are horrible
beyond belief. As far as I can see they forgot to put the fish in the bowl
that they gave me as a pair of glasses. If I can determine what my old
glasses are made from I'm going to order a pair of distant glasses and a
pair of close glasses out of the same material and insist that they make
the back curves the same.
The first question I have is, since this is a discount place that I
believe will make the switch for free but that I can't get my money back,
how insistant do I have to be about the material and back curves. The back
curves are important because I've always had enough problems switching
between even identical glasses that I don't have a pair of sunglasses and
a
pair of regular glasses that I switch back and forth between. I expect to
be stonewalled on this with a "we can't do that" or "no that isn't
important" to the implied "your nuts". I'd rather go in with would you
please do it this way because experience has shown me that this is what
works for me. To get it done right I can keep escalating my insistence
until they basically ask me to leave, but I'd much rather be nice than
demanding, but I will have a working solution. Much of this I've learned
from experience. I gave them a chance to do it their way, now they need to
do it my way. I don't trust them to either to be able to figure out what
my
current glasses are made of or to tell the truth unless it benefits them.
I went with them because I know 2 people that have had success with
them , but their prescriptions are relatively simple. The next question
how
do you find an optical place that works without spending huge amounts of
money and time to try each one . I've tried chains, discount places and an
independent, with no more or less success at one or the other. I've had
two
pair of glasses in my adult life that I've really liked. The last one is
12
years old and desperately in need of replacement. It seems that I can't
find large aviator style frames with a saddle bridge and not nose pads. I
hate nose pads. It also seems that someone is making a hell of a lot of
money on polycarbonate and progressive lenses to be pushing them with the
religious fervor that they are. I'm open to ideas.
Most progressive lenses have etchings that identify the lens manufacturer,
model, and material. Many opticians have a publication that explains all the
markings, or you can Google "progressive lens identifier".
Here is one link that has the 2002 version which should be fine for your
1996 lenses.
