Great Video! I have a pair of Essilor Varilux Lens with Transitions XTRActive and a Fire Red Mirror Coating. XTRActive Grey with Fire Red Mirror Coating Pros + All visible light wavelengths activate the XTRAactive vs. UV activates the Transitions Gen8 + Great for outdoor sports and driving, use them everyday for walking and running outside + Become much darker than Transitions Gen8, even more so when below 70 F outside + Better than Transitions Gen8 for outdoor activities and driving + Quick to darken and lighten, still work great after 1 year of daily use Cons - Prefer not to use indoors, too much light attenuation and too many internal reflections from indoor light sources - Try not to use these outside at night because of internal reflections from vehicle lights, street lights, etc. - Still usable after dusk, but prefer to wear Transitions Gen8 or non-Transitions lenses

What powder that using? I'm curious about that
