Zenni has the best intention but just to difficult to provide service from long distance. Wife filled a prescription a year ago with Zenni. Just recently went to her doctor. They checked her Zenni glasses for the prescription and found it was not the one provided by the doctor a year ago. Wife called and was advised to send glasses in for checking by Zenni. Really can't do that as she can't go without any glasses. So we are done with Zenni. Just be aware of doing business from long distance.
