I respectfully must disagree with all of the claims here regarding zenni and costco, unpopular as it may be. They are only comparable at the low end but have no matching product at the high end. I bought a pair of glasses at costco for $200 as a backup to my daily rimless wearers. First, costco and zenni don’t have any rimless options. Second, the lenses I did buy ( partial frame) were their lightest but still significantly heavier than what I replaced. Third, the lenses just didn’t have the same clarity and sharpness as my oakleys. They just don’t offer the same quality coatings and I paid for their best. After a couple of months, I caved and went back to lenscrafters for a replacement. My new Ray Bans, although expensive, are like night and day compared to Costco. Light as a feather, outstanding clarity and sharpness, extremely scratch resistant, on the whole simply remarkable to wear. Side by side comparison, exact same prescription, there’s no contest. None.

Luxottica may be overcharging, but truth is the discount brands do not carry a comparable product. Certainly you can save money at those places, but the product isn’t the same. In some sense you are getting what you pay for. You can get even better lenses from Zeiss and Nikon if you go beyond Lenscrafters, but I haven’t walked that path yet as it’s a bit beyond my budget (read: insurance), although I’ve heard excellent things.

Edit: Grammar.
