\nThese high performance Sunglasses are designed to suit a wide range of sporting activities but are specifically aimed at Watersports, delivering excellent eye protection with outstanding optical clarity and wrap around Polycarbonate lenses, which are Polarised and scratch resistant.
\nThe TR 90 Military Style frame is very light, comfortable and robust. It features a ventilated frame design to reduce misting in cold weather and has removable lenses, so you can have prescription lenses fitted if you desire to do so.
\nIn our tests, the ability to float in both Fresh and Salt water is unaffected with plastic prescription lenses up to - 4 Dioptre. We feel that you would be able to go well beyond this and still have no problem with them floating, but would always recommend conducting your own buoyancy test in shallow water after any different lenses are fitted, before going into deeper water.
