Pilots - Sunglasses are necessary
For the majority of individuals sunglasses fulfill either both or one of the two purposes: that is it acts as a statement of fashion to look “sleek and trendy and also to protect the eyes from the bright glare of the sunlight. There are wide ranges of choices available for sunglasses today. These sunglasses come from polarized to photo chromic and come in colorful shades and tints.
But, as far as pilots are concerned, sunglasses serve a more important purpose then simply serving as a statement of fashion. Sunglasses are meant to safeguard a pilot’s most vital asset during flight- vision. It is essential to have a good sunglasses pair in cockpit’s environment to increase visual performance.
These help in eliminating the harsh light emitting from the sun, reduces eye wariness, and safeguard ocular tissues from the contact to harmful effect of solar radiation. Furthermore, they help in protecting the eye of the pilot from possible collision with objects like flying debris, or a flying bird strike, or a decompression or from an aerobic maneuver.
There are infinite choices for tint for the sunglasses, but the most sought after tints are brown, gray, and gray-green, any or all three of them would be a good option for an aviator. Experts recommend the color grey tint as grey changes color the minimum. However, many pilots chose to differ, preferring gray-green or brown tints by reasoning that these colors enhance the vividness and reduces scattered violet and blue light, thereby enhancing the contrasts in blurred conditions.
The pilots should choose such a lens that screens out visible light by only 70-80%, and does not specifically distort color. The sunglasses that have tints blocking out 85% or more of visible light rays are dangerous if used by a pilot since it can result in a reduced visual activity, and that could mean a difficulty in looking at flight instruments, printed checklist and data in the area of cockpit.
It is true that lenses which are polarized are the most popular ones in the market, but experts do not recommend it for aviation purposes. It is true that are useful in blocking the light reflected from horizontal surface areas like snow or water, but polarization can result in a reduced or eliminated visibility of instruments used in flight that incorporate antiglare filters such as the latest innovation environment of glass cockpit.
The visibility when seen through the aircraft windscreen can also be interfered by these polarized lenses, as they enhance the striations in the laminated glass which may mask the visibility of another plane, which is hovering in the aircraft’s vicinity, by eliminating the light’s sparkle, which was reflected off the other aircraft’s wings or fuselage. Thus, this could result in an accident, which could otherwise have been avoided.
When exposed to ultraviolet light, the photo chromatic lenses naturally darken, and then revert back to a lighter shade when confronted by a shallow light. The lens takes a maximum of 60 seconds to darken its color, while to come back to its original shade it may take up several minutes. Most of the photo chromatic lenses can become dark as a regular sunglass but warm temperatures of more than 700 F may affect their darkening capacity.
Minimized exposure to ultraviolet light in the cockpit may also have the same effect on them. And most importantly, the photo chromatic lens in a faded state may be unclear and therefore, useless at the time of flying in the clouds or during a nighttime flight.
The choice of frame depends more on your personal taste, but the current rage are the bayonet style as they putting them on or removing them while one is wearing headsets or helmets is totally simple and hassle free. Smaller sized lenses may be impractical as they are unable to prevent an excess of visible light rays and also ultraviolet radiation from passing around the corners of lenses. Lastly, it is advised to use a strap so that the sunglasses do get accidentally dislodged.
In summer, the sunglasses serve a dual purpose- that of adding to the enchantment of the pilot and also protect his eyes from the glare that is connected with bright light, and also the harmful exposure to sun’s radiation. As sunglasses are useful an asset, they should be selected after a careful consideration when selecting the right set for flying.
Ever since the year 1982, the company, Randolph Engineering is the standard issue available for the United States military pilots. These sunglasses are manufactured in the United States of America itself and their quality of material are all more refined than the required standards of military. Therefore, when an astronaut from NASA lifts off from the launching pad to go to the outer space, they take away Randolph with them.
