Tonic Cove sunglasses are sturdy yet light-weight frames will cut through glare and increase clarity.
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.
