Review on Kickback Photochromic Adjusting Motorcycle Sunglasses Motorcycle & Powersports by Erick Bowers

But these are not photochromatic lenses. Freeze according to directions for 2 hours, then in direct sunlight. If there was a color change, my eye certainly didn't notice it. They stay yellow. I put them back in the freezer and back in direct sunlight. Drove to see if they have changed and if they are different. For the price, they're comfortable and seem to be built pretty well.
