Our Diamond range represent the pinnacle of sunglass lens technology and optical excellence. Every Diamond lens is manufactured from optical grade Polyamide – an incredibly durable material with the clarity of glass. All have an exclusive Anti-Reflective (AR) coating on the inside to reduce bounce back and an ultra-tough outer hardcoat, to help with scratch prevention. Whether classic Onyx black and Burnt Umber brown or our sophisticated Gradient Rose, Hazel and French Blue, this exclusive range has a lens to compliment your frame with technical specifications and performance to match. If nothing but the best will do, you simply can’t do better than an SFx Diamond lens. (Please see individual lens detail for information on polarization, coatings and category.)

SFx G15 Gradient
One of the strongest, lightweight and durable lenses made. All SFxUltra lenses integrate a Japanese polarization film with 99.9% efficacy rating - making it one of the best anti-glare lenses available. SFxUltra lenses are available in a wide variety of tints and gradients and can also incorporate both subtle (flash) or solid mirroring. Choose a black gradient for everyday or an extreme black silver flash, with 95% light block, for glacier skiing. These polarised lenses are the definition of style and function.
Safe, durable, lightweight with crystal clear HD performance. These non-polarized lenses are coated with a protective layer that resists scratching and repels water & sweat. All SFxEdge Lenses are made from a unique, flexible polymer that has unbelievable optical clarity. In fact, laboratory testing ranks our lenses with glass - but ours are a third of the weight, don't break, are safer and easier to install.

Great service! My lenses arrived in less than the expected time and they were so easy to fit. They are so clear compared to my old scratched lenses. Not just a cheaper way to make old scratched sunglasses as good as new but it saves the environment and has meant I can still wear my old favourite sunglasses which I can’t even replace as they do not make them any more!!!!
