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
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.
Don't scratch them. It's simple as that. Wash lens with soap. It's as simple as that.
One is SV AS +2.5 sphere 0 cyl duravision platinum uv 1.60 index (guess this is what you’re talking about) uvprotect
The other is the same but 1.25 sphere
Hope it helps
