Where It All Began Military sunglasses are often referred to as aviator sunglasses as they were first used by aviators back in the 1930's.
The large lenses were designed to give optimal vision to pilots, and the polarized lenses provided the maximum protection from the glare of the sun and its damaging UV rays.
Other military and law enforcement groups soon discovered the benefits of this style of eyewear with the wide area of coverage helping to keep the dirt and dust out of their eyes.
They were soon adopted as a standard piece of kit.
The Fashion Statement Their popularity increased dramatically after the release of the hit movie Top Gun, and suddenly all the guys wanted to look like Tom Cruise.
It seemed the girls just couldn't resist a guy wearing military sunglasses, and soon sales began to rocket.
Camouflage prints and oversized sunglasses hit the catwalk and everyone wanted to make their own fashion statement.
This type of eyewear was a perfect choice for creating the right look.
Top name designers realized the potential in offering updated versions of this eyewear.
Boutiques offer the latest versions and military surplus stores offer original designs.
Changing Designs Today's designs are much more lightweight than their predecessors due to the availability of modern materials, such as aluminum and plastic.
Lenses can be made from polycarbonate which is much lighter than glass.
Most lenses provide a 400 SPF to protect against dangerous UVA and UVB rays.
They also come in a wide range of colors.
The Hollywood Factor The 'Top Gun effect' has been replicated over and over, with fans wanting to look like their favorite movie stars.
