Professional fishermen choose the Smith Passage. Trustworthy tapered lenses, made from glass not plastic, eliminate distortion to offer crisp vision. Polarchromic technology adjusts to changing light and shadows that might otherwise hide the catch of the day. Glare from flat water and blazing sun is absorbed within the Passages polarization. When reeling in a big one, your glasses will stay put via non-slip Megol pads. Optimum coverage for large faces blocks more sun, so you can see the one that wont be getting away.
