Aviator sunglasses are an iconic eyewear style, initially employed by military pilots in the 1930s and in WWII before making their way to the masses. One factor remains constant for many — dark green lenses, although the design has seen countless iterations in recent decades. As you may guess, the color choice is not just decorative. But before we clarify that, we must go to the start of aviator sunglasses. Bausch & Lomb developed in the 1930s the aviator sunglasses. Pilots wore goggles to protect their eyes in the atmosphere, where optical risks were introduced by high altitudes. Besides the glaring sun temperatures also posed a threat. Goggles were meant to protect pilots. But, a significant issue with these goggles was fog. Temperature differences between the atmosphere inside these goggles’ goggles and out frequently caused the lenses to fog up, obscuring the view of the pilot. If a pilot chose to doff their goggles and expose themselves to the cold or the sun, the problem would be exacerbated. Such was the case with pilot Shorty Schroeder who is eyeballs froze just minutes after he removed his goggles during a record-breaking 33,000-foot high flight. Somehow, he was able to land the airplane safely. His friend would attempt to break his record a month later — at the exact same plane, no less and helped him out of the plane. Macready’s flight was a success, though he discovered that pilot goggles were in blocking light in such high 22, insufficient. He turned to Bausch & Lomb to create a solution. What they came up with was a lightweight metal frame with teardrop lenses that helped provide protection when looking below. But perhaps the most detail was the lenses themselves. Rather than a neutral grey tint, the lenses were really dark green. Because the green tint helped cut out blue light, a considerable issue for pilots flying above the cloud 26, this color choice was practical. Additionally, but green lenses have a tendency to decrease glare whilst also enhancing sharpness and contrast. The men sunglasses have been an immediate success and made their way through the military before finally hitting the scene that is civilian. Bausch & Lomb dubbed the sunnies Ray-Bans, which goes on to become its own pretty successful manufacturer. Now, the green lenses used frequently in aviators have a specific title: G-15. Though the de facto green lens of most sunglasses is your G-15 subsequent versions of this lens comprise even and a G-31 a G-50. Other companies have made their own variations of the G-15 lens, each using the exact same purpose as the original. You may not be a pilot and Even though Bausch & Lomb longer exists, the innovation continues to serve its purpose, both and on the streets.
