Transitions XTRActive gray and GEN 8 Sapphire (review)

Watch my old Transitions XTRActive lenses and my new GEN 8 Sapphire lenses transition side by side then lighten back up in real time. It takes longer than advertisements may suggest. (In the beginning of the video I say the glasses with blue temples have sapphire XTRActive lenses, but that is incorrect as that is something that does not exist. I misspoke.)
