I'm trying to decide whether or not $70 high-index aspheric 1.67 lenses are worth
the extra money.

My prescription:

Right:
sphere: -3.250
cylinder: -0.750
axis: 172

Left:
sphere: -1.500
cylinder: -0.250
axis: 180

I went to Costco today to get some eyeglasses. The guy selling the glasses
was pushing for the $70 1.67 lenses. He said that the right lens will look
REALLY thick if I get the $20 regular plastic lenses. He said that since
the frames I brought in were kind of big lengthwise, the thickness of the
right lens would really stand out. Going on his advice, I got the 1.67
lenses.

After a couple of hours, I started having second thoughts about getting the
more expensive lens. I wasn't too sure if the 1.67 lenses were worth the
extra $50. I postponed my order for now on the phone so that I could make a
more intelligent decision. Now I'm trying to decide between regular plastic
lenses (CR-39, I think) and high-index 1.67 lenses.

I plan on getting lenses for the following glasses. The size of the frame
is 50-18-140

I don't know how thick the right lens will end up looking. I plan on getting the
lenses rolled & polished, so that should reduce the thickness a bit. Based
on the prescription above, will the right lens look like a Coke bottle in
the frame I brought in? $50 is a big chunk of change for me, and I need to
decide if that money should be used for the thinner, more expensive lenses.
