Purchased the ImpactX Photochromic 2 Laser Brown lenses with a prescription insert. Great for road, gravel, and MTB. Very fast light to dark transition.
I used the old insert for my rydon frames years ago and thought it was a great solution back then. Decided to upgrade a few months ago and this new insert paired with cutline sunglasses was by far the most comfortable for biking and running.
The quality and price point is incredible especially for them being recycled options
