SOS Polarized Sunglasses: 100% UVA/UVB Protection - Featuring one-piece MLF MultiLayer Filtration lenses that provide distortion free, ophthalmic 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 sun glass lenses. SOS MultiLayer 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. Survival Optics Polarized Sunglasses are backed by a lifetime warranty.

SOS Technical Information

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 polarises in the lenses. The result is a reduction in annoying and sometimes dangerous glare.
