The technology used in our Interchangeable lenses is exactly the same as that used in our regular fixed lenses. The difference is that each frame comes with three sets of easy-to-change lenses, in different shades and colours. This allows you to choose one frame that fits you best without being concerned with whether or not you chose the right lens colour for your activities. A zipper case and a lens carrying pouch is included, so you can pack your extra lenses when you head out on longer adventures.

ONE FRAME INCLUDES 3 SETS OF LENSES:
· dark lens for medium to bright conditions
· contrast lens to increase contrast and depth perception in medium to low light conditions
· clear lens to protect against the elements in low to very low light conditions

LIGHT CONDITIONS: designed for medium to very bright light

COLOUR EFFECT: darkens colours without changing hue or contrast

VISIBLE LIGHT TRANSMISSION: 14%, category 3

UV PROTECTION: 100% UVA, UVB, UVC and harmful blue light to 400nm

FLASH COATING: This is a slight mirror coating that provides a technical look without the intensity of a full mirror. The practical purpose of this coating is to slightly reduce the intensity of direct sunlight or glare by reflecting the light before it reaches your eye.

LIGHT CONDITIONS: designed for very low to low ligh

COLOUR EFFECT: gives the illusion of more light and increases contrast by reducing blue hues

UV PROTECTION: 100% UVA, UVB, UVC and harmful blue light to 400nm

Polycarbonate is the extraordinarily durable thermoplastic that’s used in bulletproof glass, riot shields and astronaut helmets. It’s the ideal material for performance eyewear because of its high impact resistance, inherent UV protection and light weight. All of our lenses are made of polycarbonate.

All of our lenses block 100% of UVA, UVB, and UVC rays, and harmful blue light to 400nm. These harmful rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes—all great reasons to block them out.

All of our lenses are shatterproof, meaning they won’t break up into dangerous little shards when impacted. An extremely strong impact may damage the lens, but it will never shatter. If astronauts trust this material to keep their heads from exploding while on a 17,000 mph space walk, you’ll have nothing to worry about on your adventures, no matter how fast you’re going.

The lenses in all of our sunglasses are made by injecting molten polycarbonate into a mold that is specially shaped to eliminate distortion. This process makes the lenses optically correct, increasing comfort and minimizing eye fatigue.

We apply a scratch-resistant coating to all of our lenses. Though this process makes the surface of the lens considerably harder than the base lens material, it’s impossible to make the lenses completely scratch proof (short of making them from diamonds) so please care for them properly as they may still scratch under certain conditions.

A Swiss technology, this thermoplastic is the material used in all of our sunglasses (with the exception o
