I think we need to be mindful of the intended purpose of the photochromic lens: glacier travel. The lens ranges from category 1 (43-80% light transmission) to category 4 (3-8% of light transmission), and Smith states 45%-7% VLT. Although the lens isn’t the best for riding, I’d be proper pissed if I bought eyewear specifically for glacier travel but allowed too much light through.
