NTSB’s investigation hearings of the Jan 15th, 2009 US Airways’ Airbus Flight 1549 bird-strike incident which led to the ditching of the aircraft in Hudson river have generated some potential recommendations – developing an on-aircraft anti-bird technology for rounding-up and wiping-out thousands of Canada Geese. At the hearings, Airbus test pilots supported Captain Sullenberger’s decision; [...] Read more »

Selecting Sunglasses for Pilots

by iflyasa November 5, 2009 » Add the first comment.

While adding to the mystique of an aviator, sunglasses protect a pilot’s eyes from glare associated with bright sunlight and the harmful effects from exposure to solar radiation. Lenses for sunglasses that incorporate 100% ultraviolet protection are available in glass, plastic, and polycarbonate materials. Glass and CR-39® plastic lenses have superior optical qualities, while polycarbonate lenses are lighter and more impact-resistant. The choice of tints for use in the aviation environment should be limited to those that optimize visual performance while minimizing color distortion, such as a neutral gray tint with 15 to 30% light transmittance. Polarized sunglasses are not recommended because of their possible interaction with displays or other materials in the cockpit environment.

I wrote about the basic information about a Pilot’s Sunglasses in one of my posts titled Sunglasses for Pilots (click here), and then I wrote about the Materials that are available today, and how to pick the correct kind in the post titled Aviators’ Sunglasses Lens Material Options (click here). And I had promised that I will write more about the Extra Features that we need to keep in mind when selecting the best Sunglasses for Pilots, and for that matter, anyone who wants the best eye protection and quality vision. Here is the list of those extra features that you need to keep in mind as well:

Aviators’ Sunglasses Lens Material Options

In one of my previous post – Sunglasses for Pilots, we talked about why it is extremely important for a Pilot to be very careful about choosing proper quality and material for the Sunglasses. The American Optometric Association recommends wearing sunglasses that incorporate 99 – 100% UVA and UVB protection. Fortunately, UVC, the most harmful form of ultraviolet radiation, is absorbed by the atmosphere’s ozone layer before it reaches the Earth’s surface. Some scientists believe, however, that depletion of the ozone layer may allow more ultraviolet to pass through the atmosphere, making 100% ultraviolet protection a wise choice when selecting eyewear.

Pilot Vision

Vision is a pilot’s most important sense to obtain reference information during flight. Most pilots are familiar with the optical aspects of the eye. Before we start flying, we know whether we have normal uncorrected vision, whether we are farsighted or nearsighted, or have other visual problems. Most of us who have prescription lenses—contacts [...] Read more »
