Amazing experience at Lens Save Optical!! My girlfriend and I saw them on groupon and decided to give it a shot. All I can say is WOW! Got 3 pairs of designer glasses for super cheap, which is nothing I'd compare their practice to be! I've been to a few places in Calgary and the test alone took 45 minutes. 15 minutes here tops with their top of the line equipment! Dr. Kirk was a pleasure to deal with, as was the receptionist and his son who both helped us pick out glasses! Here's the kicker, we put our order in on a Thursday and got all three pairs including prescription Ray Bans on Wednesday the following week; only 6 days!!! Highly, highly recommend this place!
