Polarized lenses help deal with the reflection on the water. They have a special coating with anti-glare properties that reduce up to 98% of reflected light, ultimately reducing glare. They improve overall clarity making it possible to see more detail in the water.
Photochromic or transition lenses are a special kind of polarized lenses that have varying degrees of visible light transmission(VLT). They are able to adjust to changing light conditions. They respond to the amount of light hitting the lenses and darken or lighten accordingly. They help reduce reflections on the water and eye strain.
Some colored and mirrored lenses also reduce reflections on the water. Gray lenses reduce light transmission thus lessening brightness and glare. Blue and blue mirror tints have a gray base that helps block harsh rays from the sun as well as light reflections. Green mirror and tint lenses improve contrast and vision on sunny days while reducing color distortion.
