I went in to the optometrist planning on doing this. I did buy the frames online at least. The guy gave me convincing a spiel about how his lenses were technically better than the machine made online ones were, but about 60% of the reason I didn't buy online was he was White and [aside from his father who will retire soon if he hasn't already] he was the only specialised tradesman in the greater area who still makes them by hand in store, and I wanted to support that over giving a small amount of money to a jew/chink/jeet/whoever runs the online places.
