The optometrist at our Costco kept over-intensifying my prescription, so now I go back to my old eye doctor and just get my glasses at the Costco vision center.
I got my first eye exam in 4 years at my local Costco after my insurance no longer covered my ophthalmologist, and it was great. The appointment was quick and professional.
I went with one optometrist at a Costco, and the procedures were very basic. A few years later, at a different Costco, the optometrist was super thorough and caught a potential problem that required a visit to an ophthalmologist.
