SOS Polarized Sunglasses 100% UVA/UVB Protection - Featuring one-piece MLF Multi-Layer Filtration lenses that provide distortion free, ophthalic quality and extreme eye comfort. There are no laminates to separate and nothing to degrade the polarization as with laminated films. Laminated polarized 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 polarized sunglass lenses. SOS Multi-Layer Filtration blocks vertically-reflected light by horizontally aligning the crystalline structure of the lens. This makes them ideally suited for use around water, snow, and for driving. Avoid cheap polarized sunglasses, because hazy lenses may result in eye strain.

For years, polarized sunglasses have been used by boaters and fisherman to reduce glare from the water that they spend so much time on. In the past few years, however, the benefits of polarized sunglasses have been realized by a variety of other outdoor sports enthusiasts as well as by drivers and general use wearers. Thus, the popularity of polarized sunglasses has increased dramatically, as has availability.

The activities that utilize the benefits of polarized sunglasses the most include, water sports, skiing, golfing, biking and jogging. For these activities they offer a clearer view and eliminate glare.

They are also recommended for driving in daylight and in fact can reduce the glare that comes off a long, flat surface such as the hood of the car or a highway. Polarized sunglasses can also be used indoors by light-sensitive patients or by those exposed to bright light through windows. Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses. The result is a reduction in annoying and sometimes dangerous glare.
