TONIC Sunglasses

The clearest lenses available on the market!
Made for Southern Hemisphere conditions.
All TONIC styles feature:

Polarisation: With Tonic Eyewear’s lenses anglers have polarisation and our custom made light filtration system that delivers unsurpassed clarity and colour enhancement.
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 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.

TONIC Glass Photochromic Copper and Glass Blue Mirror lenses also feature:

Tonic’s Four Colour Spectrum Filter: Tonic's four colour integrated polarising filter system in the back of the lens: They have green which retains colour, yellow which gives high contrast when ambient light is low, brown and copper mix to give high definition.
