Ive had mine for 14 months. Expensive to buy and are not nearly as scratch resistant as coated lenses that Ive had for years. I have two other pairs that are at least 5 years old, and they have fewer scratches than these Crizals at a little over 1 year. I also need to wash them daily, so there goes the claim that they stay cleaner. Ill never spring for them again. Money down the drain, so Ill go back to my old type lenses in the future.
