Like dentists, the trick with opticians is to find a good one, and to come back.
TL:DR - I've found a good one, and will keep coming back here.
I'm very happy with the test, my prescription and my new frames.
I was with an optician in Highlands Ranch for many years, but the 30 minute drive got to be too much. This is about 5 minutes, and they're just as good, if not better.
There was a problem with the frames they ordered for me - they gave me a loaner pair in a different color, and ordered a replacement - AND an alternate colorway for me to try. Can't beat that kind of service.
New customer for life!....or until I move too far away ;)
Thoroughly recommended.
Incidentally, I checked frame and lens prices online, and they're pretty competitive, plus there's someone to fix any problem that might arise.
