Bearing the name of a device used to reflect sunlight in a fixed direction, the Oakley Heliostat Prizm Deep Water Polarized adult sunglasses are crafted with that goal in mind. They feature a wraparound design for increased coverage as well as a lightweight and durable O Matter™ frame with tall temples to help block light on the sides. In addition to protecting your eyes from the sun, this accessory comes with Prizm Deep Water Polarized lenses that are engineered to boost colours that water absorbs and minimise glare to help you see what is going on beneath the surface so you can fully enjoy your time on the water, fishing or practising your favourite water sports.
