Transitions Optical’s Vantage lenses shift from virtually clear and nonpolarized indoors to dark and polarized outdoors. (Until 2012, it was thought that polarized lenses could not become clear.) Transitions uses photochromic dyes rather than film to achieve polarization, which varies in the lenses, depending on the amount of UV exposure. I was able to test Vantage while sailfishing in Miami this past December and found them quite comfortable, with more‑than‑adequate polarization, darkness and glare reduction. Transitions says Vantage lenses also offer full UV protection, and they’re a $120 add‑on to prescription lenses.
