Whether you enjoy sailing, diving or surfing, the eyewear you choose for your water sports should provide 100 per cent protection against harmful UV-A and UV-B rays. For sunglasses without prescription lenses, look for the CE mark and EN 1836:1997 label to ensure you are properly protected. To achieve glare-free vision, experts recommend an integrated polarization filter and suitably coated lenses that are as hard-wearing and resistant to breakage as possible. The frame should be durable and robust, too, and preferably made of a strong, lightweight and shatter-proof material. Sunglasses with ZEISS Skylet® lenses are a great choice for virtually all types of water sport: available in a wide range of tints and functional designs that have been carefully tailored to activities including swimming, surfing and sailing, they offer the perfect basis for a pair of water sports glasses.
