Overall I always enjoy my experience at this eye clinic. The only thing is it would be nice to receive a full prescription including the PD for my eyes. This was not given to me because the Dr. didn't want to be responsible for that number if I was ordering glasses online. Definitely a way to try and strong arm customers into buying (very expensive) glasses there. Pretty sure PD is the same no matter where I order from...also had issues with my contacts prescription in the past because again I ordered those online so was told to convert my glasses prescription by myself which was then still missing all the eye measurements. Great place but they try to get you to spend your money on their very expensive glasses and contacts.
