    Photochromic lenses, AR coating

    I have 2 questions:

    1. Are 1.67-index lenses any worse than CR-39 in working with Transitions (gray color) photochromic tint? Or does 1.67 plastic darken as well as CR-39?

    2. Does the addition of premium AR coatings (like Crizal or Vivix) diminish the darkening ability of Transitions photochromic lenses on 1.67 plastic or CR-39?

    Probably you can drop your questions to Sponsored Forum "Smart Lens Technology By Transitions Optical".
