Straits Fly Shop is thrilled to be carrying sunglasses by Tonic Eyewear.
All Tonic Eyewear frames are made from TR90 optical grade material. They are all tough and lightweight. Our frames are designed to be comfortable and optimise block out of sunlight. Any non TR90 components are nickel or stainless steel to prevent rusting. Currently the Tonic range features high gloss black, matt black and high gloss tortoise shell designs.
All of 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.
