One trick: If you can get the prescription (they're supposed to
give it to you by law when you ask - and you might have to
remind them) - is go to zennioptical.com and play around with
different glasses. I hav...e a high prescription so mine are
$25-30 but regular prescriptions are $10-$20. You put your
numbers in - measuring between your pupils is the hardest part -
order them and wait three weeks and they come in from China. If
you screw it up - oh well, it wasn't much money. I got to play
around with purple glasses, pitch black sunglasses (bad idea
btw) - and all different kinds of frames and tints through the
years."
