I added the Crizal treatment to the glasses I purchased 13 months ago(I have progressive, transitions lenses and when I needed new glasses I added the Crizal treatment). I visited the optical store where I purchased my eyeglasses today because of the fine scratches on both lenses. I was told that the Crizal warranty is only for a year, so there was nothing they could do. I just compared my 13 month old lenses with my previous glasses(which I had for 6 years) and the old glasses don’t have anywhere near the scratches that my new glasses have. I will not pay for the Crizal treatment when I need new glasses(why pay for something that actually results in more scratches than if you don’t order the treatment?)
