SOS Polarised MLF (Multi-Layer Filtration)
SOS high definition polarized MLF (Multi-Layer Filtration lenses are one piece, distortion free, ophthalic quality, high tech polycarbonate. There are no laminates to seperate and nothing to degrade the polarization as with laminated films. Laminated polarised lenses can delaminate due to faulty bonding, aging and exposure to heat. SOS MLF is distributed evenly throughout the lens and not laminated to the lens as found on inferior polarised lenses. SOS Polarised MLF (Multi-Layer Filtration lenses block vertically-reflected light by horizontally aligning the crystalline structure of the lens.

Polycarbonate Lenses
SOS's shatterproof polycarbonate lenses are optically correct for zero distortion to provide outstanding optical performance and enhanced vision in any lighting condition. Polycarbonate is the newest development in lens materials. It is a type of LEXAN from G.E., the same material used for bullet resistant glass in autos. It is such a hard material that a special diamond grinding wheel must be used to cut the lens. To form the glasses the material is melted and then force injected into a special mold. The polycarbonate material is naturally UV absorbing, so even the clear lenses are 100% Ultraviolet protected. Polycarbonite in certain glasses is actually approved for use as safety glasses. Polycarbonate lenses are lightweight, durable, impact-resistant and the most scratch-resistant of the plastics. They are virtually break proof. Polycarbonate eyewear is the only approved eye protection for most major Police & Fire Departments. All Survival Optics Sunglasses are warranted by the manufacturer to exceed Shatter-Resistant Safety Standards. The lenses on all the Military, Sports Wrap and Xchangeable styles are 2.00mm thick as are some of the Goggles and Gripz styles the rest are a minimum of 1.75 thick.  Polarized styles have lenses 1.1mm (0.75 Blue Mirror)

Nose Grips
SOS's nose grips create a non-slip grip that keeps SOS sunglasses securely in place during athletic activity. This self-adjusting material ensures a soft feel and custom fit regardless of head shape or size.

Temples (Earstems)
The temples on SOS models are curved to shadow the contours of your head without putting pressure on your temples.

Hints
If you're in and out of the sun constantly, like a delivery driver, a cord is a must, or you have to be putting your sunglasses away all the time.

Don't leave sunglasses with plastic frames inside vehicles on hot days. You don't want your sunglasses to "melt" and lose their form.

Storage
It's always best to place your sunglasses in a case when you aren't wearing them. Not only will it help in preventing them from becoming scratched, but it will also protect them from accidentally breaking, like someone sitting on them.

Avoid placing your glasses without a case in your purse or pocket. Keys or combs can easily scratch them.

Cleaning
Clean dust and lint from your lenses with a soft cloth. An excellent suggestion is the Micro Fiber cloth or bag which we supply with all purchases. Using a Micro Fiber Cloth will ensure that the lenses do not become scratched.
