Head on over here and fill out the on-page form to get a Free Pair of Transitions Trial Decals! A piece of advice: in Step 2, choose “Average size” in order to be able to have a little room for trimming to adjust the decals to your lenses.
From the site: Simply put, Transitions lenses adapt. They adjust from clear indoors to dark outdoors. But it’s not just about light or dark; it’s about everything in between. No matter where you are, or what situation you’re in, Transitions lenses adapt to the perfect shade so you see with just the right amount of light.
