Wiley X is a leading provider of protective sunglasses and ballistic eyewear products for the U. S. Military, outdoor sports participants, and for the safety and shooting enthusiasts. Wiley X sunglasses are also the go-to choice for service members who require sunglasses that can provide both unsurpassed protection and all-day comfort. And while Wiley X sunglasses are the standard issue with the FBI, DEA, Army Rangers, Navy SEAL Teams, and Military Special Forces, their sleek designs and ANSI- and ballistic-safety ratings make them popular with civilians and weekend warriors as well.These sunglasses are available with polarized lenses on certain colors. Polarized lenses have a filter within the lens that blocks the wavelengths of light that cause glare. They can greatly enhance contrast and allow for greater depth of vision, especially in water. They are ideal for any situation where glare reduction is necessary, like driving or playing sports.
