I also agree with the first review. I found 20/20 through Dr Rudavsky, who I also found here on Yelp, and who I also thought was wonderful and thorough and thoroughly professional. And, of course, he is a real doctor, not a sales person like the dork who examined my eyes at the fancy Pittsburgh place.
As for the glasses -- couldn't be happier. Saving up to get a few more pair filled. Barry and Evan are indeed the best. I am a bit of a collector of odd/vintage frames, so I didn't have the same concern as P.D. For me, the prices for lenses alone at 20/20 were so good that I had two other pairs of frames fitted with different prescriptions.
And when one of them didn't work out for me -- through no fault of theirs, let me hasten to add -- they replaced the lenses and wouldn't let me pay.
Please read that last sentence again. Happy happy.
