If you purchase glasses at Costco Optical, verify that your prescription is filled correctly. The selection and price of men's frames is good and the opticians are very helpful and patient. However, my recent purchase of single vision glasses at Costco Optical, Sanatoga, PA, in December 2018, was not a good experience. The prescription was done incorrectly three times. I had blurry vision while wearing the glasses, so they weren't even close to being made correctly. I went back to Costco three times to have my glasses remade. Upon my return, the optician verified each time that they were made incorrectly. However, they never offered a reason or explanation as to why this kept happening. Again, the price was great for the glasses (~ $130), and they were made correctly the fourth time. But, it wasn't worth the hassle to keep returning to the store to have them remade. I'll be going back to Visionworks for all future glasses purchases, because they are always made correctly the first time and have great sales and post-sales support. It's worth the additional cost vs. Costco Optical.
