Not available in all states, but if you live in one of the states where it is, it's worth it and saves money.

It's also available for a few provinces in Canada.

How do you know if they ship to your province?

Now I really only see one problem with this. When I go and get new glasses I try on 20+ pairs to make sure which ones look the best on me. The only downfall with this site is you have to guess that it's going to look good and not make you look like a tool.

Have you tried them? Someone told me about this website the other day...I'm going to order a pair to use as a backup. If this thread is still around I'll post my opinion of them.

I just ordered a pair of sunglasses from the them yesterday.

If you buy glasses online not only can you not try them on you then have to go to an optician anyway and pay to have them fitted.

Or you can look on your current pair of glasses and they have numbers on them that tell you different measurements. On the bridge should be two numbers which is your lens width and your bridge length. On the left arm there should be the same two numbers as on the bridge plus a 3 digit number close to the left lens. The third number is your arm length. Get as close as that to possible.

You might have to take them in to have them shaped around your ears, but at least you're not spending $300 or $400 to get a pair of glasses.
