Polarisation: With Tonic Eyewear's lenses anglers have polarisation and our custom made light filtration system that delivers unsurpassed clarity and colour enhancement. The Tonic Gen2 range features all new filter systems that now deliver enhanced light transmittance and colour separation.

Crystalite Glass: Tonic is the only fishing sunglass in Australia using Crystalite Glass: the clearest glass lens currently available. Our Gen2 range now features the remarkable SLICELENS. At only 1.3mm and 60% lighter in weight than the industry norm, the SLICE is the thinnest and lightest polarised glass lens every made. So truer than ever, 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’s Four Colour Spectrum Filter: Our four colour integrated polarising filter system in the back of the lens: we have green which retains colour, yellow which gives high contrast when ambient light is low, brown and copper mix to give high definition.

Tonic’s Three Spectrum Filter: Our three colour integrated polarising filter system in the back of the lens is a unique feature of our grey lens: we have grey to give a “natural eye” viewing experience, green and aqua which give high definition and vibrant colour absorption.

Clik-Strap: Removable and adjustable safety strap.

Custom Nose Bridge: Adjustable Nose Bridge comes with our RISE, TRAKKER & YOURANIUM styles.

The photochromic copper lens is a high contrast copper bronze. This lens is photochromic so it darkens or lightens depending on ambient light conditions. This lens has been developed to give the highest quality optics in fresh water and salt water conditions. The Photo Copper can be comfortably worn all day in all light conditions.

The Neon lens is the lightest fishing lens on the market in Australia today. It brightens things up like a neon light. It picks up the reds, blues, greens and yellows and has a very broad light spectrum which allows you to see very early in the morning or late in the evening.

The grey glass has three colours integrated into the lens: grey, green and aqua. Where most grey lenses tend to flatten colour out, the Tonic grey lens defines colour. That is a big difference between Tonic and any other grey lens on the market. Just like all the Tonic lenses, the clarity is unbeatable. Our Gen2 Grey is now photochromic, adding even more versatility.

With great clarity and optics our new mirrors look and feel fantastic. With copper based green and grey based red and silver, we have all water types covered. Tonics mirrors offer high definition glare reduction and they deliver high contrast in low light conditions and a very high result when fishing. The mirror itself has been applied inside the lens and so cannot be scratched off.

Tonic’s polycarbonate lens is a great entry level to high quality optics. Extremely lightweight and hardwearing, our polycarbonate lenses are a decentred injected mould lens with anti-reflective coating on the back surface and an anti-scratch coating applied to the front and back surface.
