Silverfish is a pioneering manufacturer and designer of sunglasses for surfing, with patents granted in the U.S., Australia and South Africa. They provide "in-the-water" protection from the sun when surfers need it the most, in the reflecting water. Silverfish's eyewear is also well suited for other water sports, including windsurfing, kiteboarding and kayaking. Prescription surf sunglasses are a specialty of theirs.
