I have zeiss lenses on my glasses, they’re terrible. Full of scratches in 1.5 years. Worst money I’ve ever spent, my last no name €80 lenses went for years without a single scratch! Anecdata obviously
What, do you think they scratched them on purpose? Avoiding scratching for thousands of hours isn't actually simple, and if some brand is less scratchable then that's a real benefit.
You can choose the material you put into them. Ray-Ban Scamglasses from the Scam Shop are definitely NOT better. Even Costco glasses aren't better.
