I went to acupuncture today, then picked up my new prescription sunglasses. There's something a little off with the prescription. I agreed to try them for a week, then bring them back if my eyes don't compensate. They're guaranteed, but I get so tired of having to complain about things. My old Rx was a difficult one to get right, but this one isn't. These were covered by insurance, so I got a good price, but don't know if it's a quality lab.
