Bison Polar Black Frames
If you have a giant head and are looking for a solid sport/casual crossover, the Bison is your model.
100% UV400 PROTECTION
All of our lenses block 100% of UVA, UVB, and UVC rays and harmful, high energy light to 400nm. These rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes—all great reasons to block them out.
HYDROPHOBIC + OLEOPHOBIC COATING
An altogether misleading name, this coating isn't nearly as scared of water as water is of the coating. In fact, water runs away at first contact, leaving clear lines of sight that are free from droplets and watermarks. The Oleophobic characteristics repel dirt and grease, making the lenses very easy to clean.
All of our lenses are impact resistant, meaning they resist breaking up into dangerous little shards when impacted. If astronauts trust this material to keep their heads from exploding while on a 17,000 mph spacewalk, you’ll have nothing to worry about on your adventures, no matter how fast you’re going.
All of our lenses are made by injecting molten polycarbonate into a mould that is specially formed to eliminate distortion. This process makes the lenses optically correct (also referred to as decentred), increasing long-term 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.
