I have decent vision insurance, but I always just use them to get my vision exam paid for at Pearle Vision, who is a provider of ours. I take my prescription over to Sams Club, Sears Optical or Walmart and get my glasses done there. Pearle Vision and Lenscrafters are so expensive I can wait the week it takes to get my glasses from the others for the few hundred I'm saving!Where can i buy good Glassses in Seattle?
