This summer, the folks at Transitions invited me to get a pair of their glasses and test them out. As someone who has been a long time Transitions Signature lenses wearer, I didn't really "need" new glasses but I was curious about the other photochromatic lens technologies that were offered beyond what I already enjoyed. In particular, while I LOVED the flexibility of Signature... it really didn't eliminate my need for true sunglasses and so I ended up still carrying them with me. Transitions XTRActive however, promised to be darker and work better while driving. To test them out and provide an honest review, I've been wearing them exclusively for the past two months. I'm hooked!
