Love the visibility; no blind spots. Adjustability is great. I bought the ImpactX Photochromic 2 Black lenses. The LTV is supposed to be 9% to 74%. I think these numbers are way off. On sunny days, the lenses are quite a bit brighter than my other sunglasses. Inside, the lenses are almost clear (near 100% LTV). If I had to guess, I would say the LTV is something like 30% to 95%.
