Why does a bodyguard need sunglasses?
In spite of obvious reasons such as sun and dust protection sunglasses allow unobtrusively to observe the object without staring on it. This is the main reason to wear them.
Sunglasses hide the eyes through which an experienced person can find out a lot.
In addition hiding eyes prevents memorising of bodyguard’s appearance completely.
However not all sunglasses are suitable for bodyguards’ needs.
It is recommended to use tactical glasses in which lenses are made not from mineral glass but from polycarbonate . These ones are lighter and stronger (200 times).They are not broken into small fragments and some of polycarbonate lenses even can reject fraction.
Some of good lenses used for example in ESS glasses do not distort vision at all.
The minimum and often even absent frame allows you to continue a complete observation from uncomfortable positions such as lying without closing a full picture with a frame.
Sun protection effect allows a bodyguard not to squint losing strength and concentration on his face expression.
Only bonuses? Almost!
Sunglasses usage is not reasonable everywhere and anytime. For example wearing them inside something or in a dark time of the day does not make sense.
An easy recognisable image of a tactical bodyguard wearing shooting glasses is not relevant too. He will be noticed immediately like a bad FBI agent on Aviator.
However such useful accessory must be among bodyguard’s possessions and it is preferably to have some items.
And all drivers of personal security have to have them.
