Fishing Eyewear.
Tonic EVO Matte Black Slice Glass Lens.
Available with either Photochromic Copper SLICE Glass Lens or Photochromic Grey SLICE Glass Lens. (Non-Prescription).

Features.
Polarisation
: All Tonic Eyewear Styles have Polarised Lenses.

Crystalite Glass
: Tonic is the only fishing sunglass using Crystalite Glass: the clearest glass lens currently available.

1.7mm Lens: At only 1.7mm thick Tonic is comparably lighter than any other lens on the market, where most are 2.0mm thick. So Tonic sunglasses can be worn all day and don't feel heavy.

Decentration: Tonic makes each lens Optically Decentred which is important for viewing true depth and true distance. Decentring eliminates prism or the feeling that you are losing footing when you are walking through streams and over rocks.

Anti-Reflective Coating: Tonic has an anti-reflective coating applied to the back surface of the lens to reduce reflective glare or "bounce back" to the pupil. This is extremely important when sight fishing.
